IOUG perception: advice for Transitioning to the Oracle Cloud | killexams.com Real Questions and Pass4sure dumps

Apr 17, 2019

Seth Miller

Transitioning to the cloud may also be a daunting thought. Logging into a cloud portal for the first time and never realizing where the rest is or the way to execute probably the most basic projects can elicit self-doubt in even probably the most experienced technologist. For some, it could consider similar to starting over. this article goals to squelch that self-doubt for those getting into the Oracle Cloud by way of presenting enough competencies to get begun with Oracle Cloud Infrastructure Database functions—without delay and with self assurance.

classic Versus OCI

There are two models of Oracle Cloud. The existing “2d generation” platform is known as Oracle Cloud Infrastructure (OCI). When Oracle first entered the public cloud market, the product was referred to as Oracle Public Cloud (OPC). most of the OPC functions are still active and run separately from OCI. In most instances, the way to differentiate between them is to seek the term “classic.” This suggests that the provider is a part of the normal OPC infrastructure. OPC changed into later renamed OCI-classic. anything now not called basic is a component of OCI.

Portals

for those who first sign into your Oracle Cloud account, you're going to doubtless be on the “Dashboard” or “My functions” page. here is the precise-degree portal which has access to each OCI and OCI-classic capabilities. The slide-out pane on the left of the dashboard has a list of the entire capabilities purchasable to your account. opting for a basic service similar to “Compute classic” will bring you to a separate portal for the Compute traditional service. selecting any carrier that isn't a classic carrier similar to “Compute” will convey you to the Compute OCI service web page in the OCI portal. The difference is delicate but crucial. The classic functions have their own isolated portals. The OCI features are all a part of the equal OCI portal.

The slide-out pane on the left changes, counting on the type of portal you are in. The Dashboard portal will display the OCI-classic and OCI functions. when you are in any of the OCI functions, the pane will now not exhibit any OCI-classic capabilities however will encompass the paths to all different OCI services.

Tenancy

The long-established Oracle Cloud, now called OCI-classic, spoke of debts as “identification domains.” but that term hasn’t truly carried over to OCI. as an alternative, everything is in accordance with the theory of a “tenancy” within OCI. For all intents and functions, the tenancy can be considered the “account.”

cubicles

Multitenancy in OCI extends a ways past the database. There are myriad ways of setting apart OCI accessories and one of the crucial maximum tiers is “compartments.” booths are a logical grouping of cloud resources. Privileges (formally called IAM policies) can also be applied at the compartment stage, meaning that there are also purposeful merits of booths beyond logical separation and company. cubicles are a part of OCI handiest. not one of the traditional features will make the most of or be limited through compartments or another OCI governance components.

All OCI provider accessories are remoted by Compartment. that you may see the Compartment wherein you presently live in any provider by way of searching under the “record Scope” header on the left aspect of the reveal. If at any time you don’t see the carrier add-ons you are searching for, make certain the relevant Compartment is chosen.

The route to booths administration will also be present in the left slide-out pane below the “id” menu. A “root” Compartment is created when your account is first provisioned. before you delivery provisioning features, you're going to must create at the least one extra Compartment.

digital Cloud Networks

A digital Cloud community (VCN) is a bunch of networking add-ons used by most OCI capabilities. A VCN intently resembles a normal network, with firewall rules and quite a lot of styles of gateways to talk across internal networks and over the internet.

Most capabilities require a VCN to exist before they can also be provisioned. Some services, such as the Compute service, will supply the alternative of growing the VCN as part of the provisioning system.

The minimal advent of a VCN will handiest provision one of the vital accessories required. The easiest way of constructing bound the VCN has every little thing vital for a useful and accessible instance is to opt for “Create digital Cloud network Plus linked resources” when creating the VCN. this could add a web Gateway to allow entry to your capabilities over the information superhighway, a subnet for every of the supply Domains within the area, DNS resolution, and dynamic IP addresses.

here's where OCI differs from probably the most different fundamental cloud providers. With OCI, you ought to installation at the least one VCN and the linked substances earlier than that you could birth provisioning and the usage of other infrastructure and substances. This contrasts with some other major cloud providers where the community fundamentals are finished instantly or with the aid of default.

SSH Keys

it's required that you create a shared SSH (relaxed Shell) key pair before provisioning an illustration. a typical strategy to try this is to make use of the PuTTY suite of SSH equipment, chiefly the PuTTY Key Generator. lots of the SSH key generator tools do not store the general public key in the structure that OCI functions expect. To create the general public key file, readily copy the textual content from the key generator below the heading, “Public key for pasting into OpenSSH authorized_keys file,” and save it to a file. Don’t overlook to store the inner most key as well.

Compute

With a VCN in region and an SSH key pair created, a Compute example will also be provisioned. OCI goes beyond OCI-basic with the aid of adding the capability to provision naked metal Machines, which gives you a dedicated physical server.

as an example, to create a fundamental Linux virtual computer (VM), choose “cases” below the Compute menu from the slide-out pane on the left. When deciding on the SSH key file, choose the file onto which you copied the OpenSSH formatted public key. the entire networking components should default to the VCN add-ons you created.

It won’t take long for the VM to be in a working state, at which factor that you can log into it with SSH. When developing your SSH connection, be certain to make use of shared key authentication and decide the SSH deepest key file. The username for Oracle Linux compute instances is “opc,” which is likely one of the many remnants left over from the long-established Oracle Public Cloud. The opc consumer has permission to carried out privileged operations the usage of sudo.

Database

The OCI Database provider has must haves similar to the Compute service. here's often as a result of the incontrovertible fact that compute situations are created to assist the database.

select “bare metallic, VM, and Exadata” under the “Database” heading from the slide-out pane on the left. make sure the suitable Compartment is chosen and choose “Launch DB device.”

 “shape” shows the dimension of the compute instance(s) a good way to support the database. The shape quantity suggests the compute potential of the illustration. the primary number shows the hardware platform on which the illustration will run: 1 shows that the example will run on an Oracle X5 server, whereas 2 indicates the instance will run on an Oracle X7 server. The 2d number suggests the variety of CPU cores that could be allotted. making a choice on a shape with a couple of CPU will can help you select up to 2 nodes for an non-compulsory RAC (true software Clusters) database configuration.

 “utility editions” shows that definite database points are enabled. here listing indicates which edition and lines are enabled for each and every choice. each and every commercial enterprise edition includes the aspects of the reduce enterprise editions.

  • commonplace version—Oracle Database regular version 2
  • enterprise version—Oracle Database commercial enterprise version, data covering and Subsetting Pack, Diagnostics and Tuning Packs, and real software testing
  • commercial enterprise excessive efficiency—Multitenant, Partitioning, superior Compression, superior protection, Label safety, Database Vault, OLAP, superior Analytics, Spatial & Graph, Database Lifecycle administration Pack, and Cloud administration Pack for Oracle Database
  • enterprise excessive efficiency—lively records shield, In-reminiscence Database, and RAC
  • special consideration should still be taken when choosing “License type” since the rate change is gigantic. as an example, the usage of “Pay as You Go” pricing for a single intense performance VM, the bring Your own License (BYOL) cost is approximately $0.29 per CPU per hour versus the included license charge of $2.52 per CPU per hour. including the license makes the illustration nearly nine times extra costly.

    The “available Storage dimension” choice is a little misleading because it most effective money owed for a element of what Oracle will really cost for storage for this VM. The “complete Storage size” reflects the whole storage consumed by means of the VM. The purchasable storage dimension is the measurement of the +records ASM disk neighborhood. The +RECO disk community will even be created with 256GB of area. The storage allotted to the OS makes up the leisure. picking 256GB will influence in a total storage allocation of 712GB. choosing a bigger storage size only impacts the measurement of the +records disk neighborhood.

    The obtainable database versions as of February 2019 are 18.0, 12.2.0.1, 12.1.0.2, and 11.2.0.four. except for edition eleven.2, the created database can be a multitenant database, even with no matter if you choose to create a pluggable database (PDB) all through the provisioning manner.

    The direction ahead

    Navigating Oracle Cloud Infrastructure Database functions can be a bit overwhelming in the beginning. besides the fact that children, creating Compute and Database instances in OCI is relatively effortless as Oracle has constrained most of the alternate options purchasable when configuring an Oracle Database gadget. one of the vital terminology may well be unfamiliar however it should now not be difficult to master for a pro Oracle DBA transitioning to a cloud database architect.

    Managing OCI Database situations once they're created poses extra challenges. The next article in this collection will verify database administration and administration projects such as backups, pluggable databases, records defend, and client networking.

    IOUG Insight: Tips for Transitioning to the Oracle Cloud | killexams.com real questions and Pass4sure dumps

    Apr 17, 2019

    Seth Miller

    Transitioning to the cloud can be a daunting thought. Logging into a cloud portal for the first time and not knowing where anything is or how to execute the most basic tasks can elicit self-doubt in even the most experienced technologist. For some, it may feel similar to starting over. This article aims to squelch that self-doubt for those moving into the Oracle Cloud by providing enough knowledge to get started with Oracle Cloud Infrastructure Database Services—quickly and with confidence.

    Classic Versus OCI

    There are two versions of Oracle Cloud. The current “second generation” platform is called Oracle Cloud Infrastructure (OCI). When Oracle first entered the public cloud market, the product was called Oracle Public Cloud (OPC). Many of the OPC services are still active and run separately from OCI. In most cases, the way to differentiate between them is to look for the term “Classic.” This indicates that the service is part of the original OPC infrastructure. OPC was later renamed OCI-Classic. Anything not referred to as Classic is part of OCI.

    Portals

    When you first sign into your Oracle Cloud account, you will probably be on the “Dashboard” or “My Services” page. This is the top-level portal which has access to both OCI and OCI-Classic services. The slide-out pane on the left of the dashboard has a list of all of the services available to your account. Selecting a Classic service such as “Compute Classic” will bring you to a separate portal for the Compute Classic service. Selecting any service that is not a Classic service such as “Compute” will bring you to the Compute OCI service page in the OCI portal. The difference is subtle but important. The Classic services have their own isolated portals. The OCI services are all part of the same OCI portal.

    The slide-out pane on the left changes, depending on the type of portal you are in. The Dashboard portal will show the OCI-Classic and OCI services. Once you are in any of the OCI services, the pane will no longer show any OCI-Classic services but will include the paths to all other OCI services.

    Tenancy

    The original Oracle Cloud, now called OCI-Classic, referred to accounts as “identity domains.” But that term hasn’t really carried over to OCI. Instead, everything is based on the concept of a “tenancy” within OCI. For all intents and purposes, the tenancy can be considered the “account.”

    Compartments

    Multitenancy in OCI extends far beyond the database. There are myriad ways of isolating OCI components and one of the highest levels is “Compartments.” Compartments are a logical grouping of cloud resources. Privileges (officially called IAM Policies) can also be applied at the compartment level, meaning that there are also practical benefits of compartments beyond logical separation and organization. Compartments are part of OCI only. None of the Classic services will utilize or be constrained by compartments or any other OCI governance components.

    All OCI service components are isolated by Compartment. You can see the Compartment in which you currently reside in any service by looking under the “List Scope” header on the left side of the screen. If at any time you don’t see the service components you are looking for, make sure the correct Compartment is selected.

    The path to Compartments administration can be found in the left slide-out pane under the “Identity” menu. A “root” Compartment is created when your account is first provisioned. Before you start provisioning services, you will have to create at least one additional Compartment.

    Virtual Cloud Networks

    A Virtual Cloud Network (VCN) is a group of networking components used by most OCI services. A VCN closely resembles a traditional network, with firewall rules and various types of gateways to communicate across internal networks and over the internet.

    Most services require a VCN to exist before they can be provisioned. Some services, such as the Compute service, will give the option of creating the VCN as part of the provisioning process.

    The minimal creation of a VCN will only provision some of the components required. The easiest way of making sure the VCN has everything needed for a functional and accessible instance is to select “Create Virtual Cloud Network Plus Related Resources” when creating the VCN. This will add an Internet Gateway to allow access to your services over the internet, a subnet for each of the Availability Domains in the region, DNS resolution, and dynamic IP addresses.

    This is where OCI differs from some of the other major cloud providers. With OCI, you must set up at least one VCN and the associated resources before you can start provisioning and using other infrastructure and resources. This contrasts with some other major cloud providers where the network basics are done automatically or by default.

    SSH Keys

    It is required that you create a shared SSH (Secure Shell) key pair before provisioning an instance. A common way to do this is to use the PuTTY suite of SSH tools, specifically the PuTTY Key Generator. Many of the SSH key generator tools do not save the public key in the format that OCI services expect. To create the public key file, simply copy the text from the key generator under the heading, “Public key for pasting into OpenSSH authorized_keys file,” and save it to a file. Don’t forget to save the private key as well.

    Compute

    With a VCN in place and an SSH key pair created, a Compute Instance can be provisioned. OCI goes beyond OCI-Classic by adding the ability to provision Bare Metal Machines, which gives you a dedicated physical server.

    For example, to create a basic Linux Virtual Machine (VM), select “Instances” under the Compute menu from the slide-out pane on the left. When choosing the SSH key file, select the file onto which you copied the OpenSSH formatted public key. All of the networking components should default to the VCN components you created.

    It won’t take long for the VM to be in a running state, at which point you can log into it with SSH. When setting up your SSH connection, make sure to use shared key authentication and choose the SSH private key file. The username for Oracle Linux compute instances is “opc,” which is one of the many remnants left over from the original Oracle Public Cloud. The opc user has permission to performed privileged operations using sudo.

    Database

    The OCI Database service has prerequisites similar to the Compute service. This is mostly due to the fact that compute instances are created to support the database.

    Select “Bare Metal, VM, and Exadata” under the “Database” heading from the slide-out pane on the left. Make sure the correct Compartment is selected and select “Launch DB System.”

     “Shape” indicates the size of the compute instance(s) that will support the database. The shape number indicates the compute capability of the instance. The first number indicates the hardware platform on which the instance will run: 1 indicates that the instance will run on an Oracle X5 server, while 2 indicates the instance will run on an Oracle X7 server. The second number indicates the number of CPU cores that will be allocated. Choosing a shape with more than one CPU will allow you to select up to two nodes for an optional RAC (Real Application Clusters) database configuration.

     “Software Editions” indicates that certain database features are enabled. The following list indicates which version and features are enabled for each option. Each Enterprise edition includes the features of the lower Enterprise editions.

  • Standard Edition—Oracle Database Standard Edition 2
  • Enterprise Edition—Oracle Database Enterprise Edition, Data Masking and Subsetting Pack, Diagnostics and Tuning Packs, and Real Application Testing
  • Enterprise High Performance—Multitenant, Partitioning, Advanced Compression, Advanced Security, Label Security, Database Vault, OLAP, Advanced Analytics, Spatial & Graph, Database Lifecycle Management Pack, and Cloud Management Pack for Oracle Database
  • Enterprise Extreme Performance—Active Data Guard, In-Memory Database, and RAC
  • Special consideration should be taken when selecting “License Type” because the price difference is significant. For example, using “Pay as You Go” pricing for a single Extreme Performance VM, the Bring Your Own License (BYOL) cost is approximately $0.29 per CPU per hour versus the included license cost of $2.52 per CPU per hour. Including the license makes the instance almost nine times more expensive.

    The “Available Storage Size” option is a little misleading because it only accounts for a portion of what Oracle will actually charge for storage for this VM. The “Total Storage Size” reflects the total storage consumed by the VM. The available storage size is the size of the +DATA ASM disk group. The +RECO disk group will also be created with 256GB of space. The storage allocated to the OS makes up the rest. Selecting 256GB will result in a total storage allocation of 712GB. Selecting a larger storage size only affects the size of the +DATA disk group.

    The available database versions as of February 2019 are 18.0, 12.2.0.1, 12.1.0.2, and 11.2.0.4. With the exception of version 11.2, the created database will be a multitenant database, regardless of whether you choose to create a pluggable database (PDB) during the provisioning process.

    The Path Forward

    Navigating Oracle Cloud Infrastructure Database Services can be a little overwhelming at first. However, creating Compute and Database Instances in OCI is relatively easy as Oracle has limited many of the options available when configuring an Oracle Database system. Some of the terminology may be unfamiliar but it should not be difficult to master for a seasoned Oracle DBA transitioning to a cloud database architect.

    Managing OCI Database Instances once they are created poses additional challenges. The next article in this series will examine database management and administration tasks such as backups, pluggable databases, Data Guard, and client networking.


    Oracle Certification Guide: Overview and Career Paths | killexams.com real questions and Pass4sure dumps

    Oracle offers a multitude of hardware and software solutions designed to simplify IT. Perhaps best known for its premier database software, the company also offers cloud solutions, servers, engineered systems, storage and more. Oracle has more than 430,000 customers in 175 countries, about 138,000 employees and exceeds $37.7 billion in revenues.

    Over the years, Oracle has developed an extensive certification program. Today, it includes six certification levels that span nine different categories with more than 200 individual credentials. Considering the depth and breadth of this program, and the number of Oracle customers, it's no surprise that Oracle certifications are highly sought after.

    Oracle Certification Program Overview

    Oracle's certification program is divided into these nine primary categories:

  • Oracle Applications
  • Oracle Cloud
  • Oracle Database
  • Oracle Enterprise Management
  • Oracle Industries
  • Oracle Java and Middleware
  • Oracle Operating Systems
  • Oracle Systems
  • Oracle Virtualization
  • Additionally, Oracle's credentials are offered at six certification levels:

  • Junior Associate
  • Associate
  • Professional
  • Master
  • Expert
  • Specialist
  • Most Oracle certification exams are proctored, cost $245, and contain a mix of scored and unscored multiple-choice questions. Candidates may take proctored exams at Pearson VUE, although some exams are offered at Oracle Testing Centers in certain locations. Some exams, such as Oracle Database 12c: SQL Fundamentals (1Z0-061) and Oracle Database 11g: SQL Fundamentals (1Z0-051), are also available non-proctored and may be taken online. Non-proctored exams cost $125. Check the Oracle University Certification website for details on specific exams.

    Oracle Applications and Cloud Certifications

    The Oracle Applications certification category offers more than 60 individual credentials, covering 13 products or product groups, such as Siebel, E-Business Suite, Hyperion, JD Edwards EnterpriseOne and PeopleSoft. The majority of these certifications apply to Certified Implementation Specialists for some specific application, with various Certified Expert credentials also available. The Application certifications are geared toward individuals with expertise in selling and implementing specific Oracle solutions.

    Oracle's newest certification category is Oracle Cloud, which covers Java Cloud as well as a number of Oracle Cloud certifications, including Oracle Database Cloud. Credentials are offered in seven sub-categories:

  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS), including Data Management, Application Development, Management Cloud and Mobile Cloud Service
  • Software as a Service (SaaS) – Oracle Customer Experience Cloud, including Service, Sales, Marketing and CPQ Cloud

    Oracle Database Certifications

    Certifications in Oracle's Database category are geared toward individuals who develop or work with Oracle databases. There are three main categories: Database Application Development, MySQL and Oracle Database.

    Note: Oracle Database 12c was redesigned for cloud computing (and is included in both the Cloud and Database certification categories). The current version is Oracle Database 12c R2, which contains additional enhancements for in-memory database and multitenant architecture. MySQL 5.6 has been optimized for performance and storage, making it capable of handling bigger data sets. Whenever a significant version of either database is released, Oracle updates its certifications exams over time. If an exam isn't available for the latest database release, candidates can take a previous version of the exam and then an update exam when it becomes available.

    Oracle currently offers the Oracle Database Foundations Certified Junior Associate, Oracle Certified Associate (OCA), Oracle Certified Professional (OCP), Oracle Certified Master (OCM), Oracle Certified Expert (OCE) and Specialist paths for Oracle Database 12c. In addition, Oracle offers the OCA credential for Oracle Database 12c R2 and an upgrade path for the OCP credential. Because many of these certifications are highly popular within the Oracle Certification Program, they provide additional exam details and links in the following sections. 

    Other Various Database Certifications Oracle Enterprise Management Certifications

    The Enterprise Management certifications cover Oracle Enterprise Manager.    

    The Oracle Enterprise Manager 11g Certified Implementation Specialist certification is geared toward Oracle PartnerNetwork members but is available to all candidates. This certification recognizes professionals who implement Oracle Enterprise Manager. You must pass one exam (1Z0-530) to obtain this certification. Interested candidates should note that this exam is slated to retire on May 31, 2018.

    The Oracle Enterprise Manager 12c Certified Implementation Specialist exam (1Z0-457) covers more management functions (for applications, databases, middleware, systems and storage in various environments). In addition, it covers architecture, installation and deployment, implementation and support, reporting and extensibility.

    Oracle Database Foundations Certified Junior Associate

    The Oracle Database Foundation Certified Junior Associate credential targets individuals who have participated in the Oracle Academy program through a college or university program, computer science and database teachers, and individuals studying databases and computer science. As a novice-level credential, the Certified Junior Associate aims at individuals with limited hands-on experience working with Oracle Database products. To earn the credential, candidates must pass the Oracle Database Foundations (novice-level exam) (1Z0-006).

    Oracle Certified Associate (OCA) -- Oracle Database 12c Administrator

    The OCA certification measures the day-to-day operational management database skills of DBAs. Candidates must pass a SQL exam and another on Oracle Database administration. Candidates can choose one of the following SQL exams:

  • Oracle Database 12c SQL (1Z0-071)
  • Oracle Database 12c: SQL Fundamentals (1Z0-061)
  • Oracle Database 11g: SQL Fundamentals I (1Z0-051)
  • Candidates must also pass the Oracle Database 12c: Installation and Administration (1Z0-062) exam.

    Oracle Certified Associate -- Oracle Database 12cR2 Administrator

    To earn the Oracle Database 12cR2 OCA credential, candidates must first earn either the Oracle Database SQL Certified Associate, Oracle Database 11g Administrator Certified Associate, or the Oracle Database 12c Administrator Certified Associate.  In addition, candidates are required to pass the Oracle Database 12cR2 Administration exam (1Z0-072).

    Oracle Certified Professional (OCP) -- Oracle Database 12c Administrator

    The OCP certification covers more advanced database skills. You must have the OCA Database 12c Administrator certification, complete the required training, complete a course submission form and pass the Oracle Database 12c: Advanced Administration (1Z0-063) exam.

    Professionals who possess either the Oracle Database 11g Administrator Certified Professional or Oracle Database 12c Administrator Certified Professional credential may upgrade to the Oracle Database 12cR2 Administration Certified Professional credential by passing the Oracle DBA upgrade exam (1Z0-074).

    Oracle Certified Master (OCM) -- Oracle Database 12c Administrator

    To achieve OCM Database 12c Administrator certification, you must have the OCP Database 12c Administrator certification, complete two advanced courses, and pass the Oracle Database 12c Certified Master Exam (12COCM), complete the course submission form, and submit the Fulfillment Kit request.

    Oracle also offers the Oracle Database 12c Maximum Availability Certified Master certification, which requires three separate credentials, including the Oracle Database 12c Administrator Certified Master, Oracle Certified Expert, Oracle Database 12c-RAC and Grid Infrastructure Administration, and Oracle Certified Expert, Oracle Database 12c – Data Guard Administration.

    Oracle Certified Expert (OCE) -- Oracle Database 12c

    The OCE Database 12c certifications include Maximum Availability, Data Guard Administrator, RAC and Grid Infrastructure Administrator, and Performance Management and Tuning credentials. All these certifications require prerequisite certifications. Performance Management and Tuning takes the OSP Database 12c as a prerequisite, while Data Guard Administrator candidates have the choice of earning either the OCP Database 12c or 11g credential. The RAC and Grid Infrastructure Administrator provides candidates the most flexibility, allowing candidates to choose from the OCP Database 11g, OCP Databases 12c, Oracle Certified Expert – Real Application Clusters 11g and Grid Infrastructure Administration, or OCE Database 10g Real Applications Clusters Administration.

    Once the prerequisite credentials are met, candidates can then achieve Data Guard Administrator, RAC and Grid Infrastructure Administrator or Performance Management and Tuning by passing one exam. Achieving OCP 12c plus the RAC and Grid Infrastructure Administration and Data Guard Administration certifications earns the Maximum Availability credential.

    Oracle Database Certified Implementation Specialist

    Oracle also offers three Certified Implementation Specialist credentials: the Oracle Real Application Clusters 12c, Oracle Database Performance and Tuning 2015, and Oracle Database 12c. Specialist credentials target individuals with a background in selling and implementing Oracle solutions. Each of these credentials require candidates to pass a single exam to earn the designation.  

    Oracle Industries Certifications

    Oracle Industries is another sizeable category, with more than 25 individual certifications focused on Oracle software for the construction and engineering, communications, health sciences, insurance, tax and utilities industries. All these certifications are Certified Implementation Specialists for the various Oracle industry products, which means they identify individuals who are proficient in implementing and selling industry-specific Oracle software.

    Oracle Java and Middleware Certifications

    The Java and Middleware certifications are spread across several subcategories, such as Business Intelligence, Application Server, Cloud Application, Data Integration, Identity Management, Mobile, Java, Oracle Fusion Middleware Development Tools and more. Java and Middleware credentials represent all levels of the Oracle Certification Program — Associate, Professional and so on — and include Java Developer, Java Programmer, System Administrator, Architect and Implementation Specialist.

    The highly popular Java category has certifications for Java SE (Standard Edition), and Java EE (Enterprise Edition) and Web Services. Several Java certifications that require a prior certification accept either the corresponding Sun or Oracle credential.

    Oracle Operating Systems Certifications

    The Oracle Operating Systems certifications include Linux and Solaris. These certifications are geared toward administrators and implementation specialists.

    The Linux 6 certifications include OCA and OCP Linux 6 System Administrator certifications, as well as an Oracle Linux Certified Implementation Specialist certification. The Linux 6 Specialist is geared to partners but is open to all candidates. Both the Linux OCA and Specialist credentials require a single exam. To achieve the OCP, candidates must first earn either the OCA Linux 5 or 6 System Administrator or OCA Linux Administrator (now retired) credential, plus pass an exam.

    The Solaris 11 certifications include the OCA and OCP System Administrator certifications as well as an Oracle Solaris 11 Installation and Configuration Certified Implementation Specialist certification. The OCA and OCP Solaris 11 System Administrator certifications identify Oracle Solaris 11 administrators who have fundamental knowledge of and base-level skills with the UNIX operating system, commands, and utilities. As indicated by its name, the Implementation Specialist cert identifies intermediate-level implementation team members who install and configure Oracle Solaris 11.

    Oracle Systems Certifications­

    Oracle's Systems certifications include Engineered Systems (Big Data Appliance, Ex­­adata, Exalogic Elastic Cloud, Exalytics, and Private Cloud Appliance), Servers (Fujitsu and SPARC) and Storage (Oracle ZFS, Pillar Axiom, Tape Storage, Flash Storage System). Most of these certifications are geared toward individuals who sell and implement one of the specific solutions. The Exadata certification subcategory also includes Oracle Exadata X3, X4 and X5 Expert Administrator certifications for individuals who administer, configure, patch and monitor the Oracle Exadata Database Machine platform.

    Oracle Virtualization Certifications

    The Virtualization certifications cover Oracle Virtual Machine (VM) Server for X86. Oracle offers two Certified Implementation Specialists credentials, one targeting Oracle VM 3.0 for X86 and the other focused on VM 2.0 for X86. Both specialist credentials recognize individuals who sell and implement Oracle VM solutions.  

    The Oracle VM 3.0 for x86 Certified Implementation Specialist Certification is geared toward the intermediate-level team member who is proficient in installing OVM 3.0 Server and OVM 3.0 Manager components, discovering OVM Servers, configuring network and storage repositories and more. Candidates interested in the VM 2.0 credential should note that the exam retires on May 31, 2018.

    Related Jobs and Careers

    The sheer breadth and depth of Oracle's certification program is rife with opportunity for professionals who want to work with Oracle technologies, or who already do and want their skills to be recognized and validated. Although there are many specific Oracle products to specialize on in varying capacities, the main job roles are administrators, architects, programmers/developers and implementation specialists.

    Every company that runs Oracle Database, Oracle Cloud, Oracle Linux or Solaris, Oracle operating systems and so on needs qualified administrators to deploy, maintain, monitor and troubleshoot these solutions. They also need architects to plan and design solutions that meet business needs and are appropriate to the specific environments in which they’re deployed.

    On the development front, ComputerWorld indicates that programmers and developers continue to be "leading players in the IT world." That magazine ranks associated skills as the most sought-after by hiring managers in 2017, tied with help desk support. (Database administration isn't far behind.) A quick search on Indeed.com results in over 12,000 hits for "Oracle developer," which is a great indication of both need and desire. Not only do developers create and modify Oracle software, they often must know how to design software from the bottom up, package products, import data, write scripts and develop reports.

    And of course, Oracle and its partners will always need implementation specialists to sell and deploy the company's solutions. This role is typically accountable for tasks that must be accomplished to get a solution up and running in a client's environment, from creating a project plan and schedule, to configuring and customizing a system to match client specifications.

    Oracle Training and Resources

    It's not surprising that Oracle has an extensive library of exam preparation materials. Check the Oracle University website (education.oracle.com) for hands-on instructor-led training, virtual courses, training on demand, exam preparation seminars, practice exams and other training resources.

    A candidate's best bet, however, is to first choose a certification path and then follow the links on the Oracle website to the required exam(s). If training is recommended or additional resources are available for a particular exam, Oracle lists them on the exam page.

    Another great resource is the Oracle Learning Paths web page, which provides a lengthy list of Oracle product-related job roles and their recommended courses.


    Oracle Exadata 101: Taming the Mammoth | killexams.com real questions and Pass4sure dumps

    Iron Man uses Exadata (Image Source — https://goo.gl/Mwt8mA)

    Whenever I used to hear this term called as “Exadata” — I’d think to myself — What is Exadata anyway? Is it some kind of a database? A storage appliance? An extremely fast server?

    I was under the impression that there’s something very complex and a very technically challenging architecture behind it which probably would be way too difficult to understand.

    Apparently, I was right! ;)

    When I started working first with Exadata, in my first consulting experience, my learning curve was fairly steep and I had to grasp complexities of the project quickly, understand and implement Exadata with a team of DBAs deployed at an aviation client’s environment.

    It could be with your case that you’re currently a DBA and your client may or may not have an Exadata environment. They as DBAs always have an itch to learn and try something new every time there’s a new feature, version or even a product is announced. Thankfully, I had the opportunity to play with Exadata thus I decided to get my hands dirty.

    Disclaimer — Please get used to the following terms when you’re learning Exadata for the first time — they can be used interchangeably to describe the Exadata components (wink wink) — “extreme”,”smart”,”intelligent”,”flash”

    Before I deep dive into architectural components and how and why things have been setup the way they are in Exadata, I’d like to confess that I’m still learning my around with this mammoth of a machine. It’s fairly interesting to see the evolution of Exadata with time.

    <history>- Exadata is an offshoot of Storage Appliance for Grid Environments(SAGE) project, the working name for Oracle Exadata Database Machine, began about three years before the product’s final release in 2008. It’s a database machine designed by Oracle to run Oracle database software and is a combination of compute (database) and storage systems. Starting with version X1, Exadata has come a long way! </history>

    In any typical bare-metal server, the ROI on investments basically depends on how fast can you serve your clients through your applications. For this you definitely need a robust IT infrastructure, most of the servers which are there as of now follow the scale-up architecture, but Exadata follows scale-out architecture. Since everything boils down to one word “performance”.

    I am skipping the hardware configuration part of Exadata, since Oracle itself has shared a lot of information on the current hardware configuration here for Exadata X-6 — http://www.oracle.com/technetwork/database/exadata/exadata-x6-2-ds-2968790.pdf.

    The latest version of Exadata that has been released is X-6. X-6 offers umpteen benefits compared to it’s predecessors, just keep in mind that it’s also an expensive investment. https://cloud.oracle.com/database/exadata/pricing. Just cautionary price sharing. :)

    Exadata is made up following components –

    1) Database Servers aka Compute Nodes — where Oracle database resides.

    2) Exadata Storage Cells aka Storage Nodes — uses a command line utility called as CellCLI to manage storage.

    3) InfiniBand switches — for high speed (read extreme) connectivity between storage and database servers.

    4) PDU and Ethernet Switches — Extra PDUs (Power Distribution Units) in case of any failure for the sake of redundancy.

    (Image Source — https://goo.gl/QSlULs)

    Initially, Exadata offered two flavours of Exadata Storage servers — High Performance and High Capacity but after X5, they changed to High Performance and Extreme Flash storage.

    The advantage of Exadata Storage server Extreme Flash is that it’s performance is orders of magnitude faster than traditional storage array architectures, and is also much faster than current all-flash storage arrays. Oracle also guarantees that the performance of extreme flash won’t wean off with time.

    Now, let’s understand what kind of things to expect when you start working on Oracle Exadata database machine for the first time. In the Database Servers aka Compute Nodes have following software components pre-configured when you get the brand new rack installed on your premises -

    1) OS (Oracle Enterprise Linux Flavour)

    2) Oracle Home (has 2 primary homes — one for the database and another for the grid infrastructure)

    3) RAC and ASM pre-configured

    4) DBFS for sharing the file system for Oracle internal files

    In the Exadata Storage Cells or Servers have following software components pre-configured -

    1) OS (Oracle Enterprise Linux Flavour)

    2) CELLSRV (Cell Server)

    3) Management Server (MS)

    4) Restart Server (RS)

    Following X-5, Oracle introduced Exadata with Extreme Smart Flash Cache. With the X5s, you need to choose between the High Capacity and High Performance cells with regards to the number of Flash cards which come with the configuration. Since the X5s High Performance Storage Servers do not have any hard disks for database storage, the Flash devices will be used to store database files persistently in addition to acting as a storage layer cache for the RDBMS layer I/O requests.

    <MagicSauce> iDB protocol — Oracle developed the iDB protocol to run across the InfiniBand network. The iDB protocol is not available to databases running on non-Exadata hardware. iDB is mainly used for predicate filtering which is the cherry on top offering for query offloading . The iDB protocol used to interact with the Exadata storage cells includes the predicate information in its requests, predicate filtering is accomplished by performing the standard filtering operations at the storage level before returning the data. All ASM disks on Exadata are accessed via the iDB protocol. </MagicSauce>

    I’d discuss the advantages of Oracle Exadata where it scores the most and why you or your client can go ahead with Exadata as an investment for your business.

    1) Time to Market — This is something that every IT organization deals with, from the project kick-off till it’s implementation and production takes a long time. Exadata as being an engineered system which is pre-configured before it’s delivered to you. It does end up saving many man hours on setting up the infrastructure. Also, Exadata can house all your PROD/DEV/TEST environments into one.

    2) RAC Ready — Exadata comes pre-configured with ASM and RAC, which saves your DBA’s time to configure everything from scratch.

    3) Single Vendor — “The buck stops here.” Oracle owns the whole stack so there cannot be and will not be any blame game when there’s any issue. So whether it’s database, hardware or any network issue, Oracle is responsible for 100% of it.

    Lastly, as I am myself preparing for Exadata Certification, I’d like to share that thankfully, Exadata certification track does not yet require one to have a prior OCA/OCP certification.
