Oracle places its 11g database in Amazon’s cloud | Real Questions and Pass4sure dumps

Oracle Corp. is offering its 11g database, Fusion Middleware and business manager products via Amazon web capabilities’ Elastic Compute Cloud (EC2), the vendor announced Monday at the beginning of its OpenWorld convention in San Francisco.

The seller will additionally let shoppers use existing application licenses on EC2 at no additional charge.

To help valued clientele arise and operating on EC2, Oracle has developed a collection of Amazon machine photographs (AMIs). These enable clients to spool up new virtual machines already provisioned with 11g, Fusion Middleware and Oracle commercial enterprise Linux inside a few minutes, the business noted.

Oracle also announced relaxed Backup Cloud Module, a utility kit in response to Oracle at ease Backup that allows for consumers to backup databases to Amazon standard Storage provider. Backups may also be encrypted and the module is integrated with Oracle restoration supervisor and enterprise supervisor.

The bulletins are “a vital, online game-altering flow for both Oracle and Amazon,” Forrester analysis analyst James Kobielus talked about by way of electronic mail Monday. “via allowing database and middleware licenses — and statistics — to be moved to the Amazon cloud with out incurring extra Oracle license expenses, it makes cloud-based hosting an attractive alternative for Oracle’s large, international customer base,” he introduced. “Of course, it remains to be viewed how Amazon will cost to host Oracle applications and databases in EC2 or to backup gigantic facts sets to S3.” protection concerns as well because the declining expenses of scalable, on-premises grid storage products may additionally discourage some customers from tapping the Amazon features, in accordance with Kobielus.

That stated, Oracle’s announcement may still have a macro impact on the market, as it “units the stage for extra virtualization of all leading database, facts warehousing, and storage providers’ product stacks,” Kobielus mentioned. “so far, Oracle is the only one of the main [database/data warehousing] vendors that has moved its relational database to Amazon, so it can be regarded a first-mover in that regard.”

It’s seemingly that Oracle will look to assist different cloud structures besides Amazon in the future, Kobielus mentioned.

but other providers, such IBM or Teradata, can also not are looking to support their shoppers moving database installations to 3rd-birthday party features, and can in its place decide to offer their personal hosted features, in accordance with Kobielus.

Introduction to Oracle enterprise manager 11g | Real Questions and Pass4sure dumps

be taught what's new in Oracle business supervisor 11g, and the way you will benefit by means of gaining knowledge of to make use of it.

For domestic use and gaining knowledge of functions, it’s very normal to create a brand new Oracle database the usage of the Database Configuration Assistant (DBCA). along the manner, probably the most screens in Oracle widely wide-spread Installer gifts you with an option to configure business manager.

Step 4 of 12, Database Configuration Assistantfigure 1 - Step 4 of 12, Database Configuration Assistant

The options shown in figure 1 are standard: you’re going to get Database manage configured at the conclusion, and the business supervisor configuration is relatively lots blown off. So, what does it take to configure enterprise supervisor? A disabled merchandise on the DBCA window suggests that no administration service agent turned into found, and that is a key piece in getting DBCA to respect that enterprise manager is even a chance. youngsters, earlier than that may also take area, there is a very good bit of setup backyard of DBCA executed until now.

with out an agent, what you get with a single database is the Database manage edition of commercial enterprise supervisor. The repository for what is collected statistics-smart in EM is the database you simply created, and the schema or owner is SYSMAN. With an agent (along with other components exterior to the database), your new database may also be managed by means of commercial enterprise supervisor and the repository can are living in different places. during this case, Database handle graduates to Grid control. The illustration beneath suggests the architecture you’re more likely to stumble upon in a fundamental setup.

Installing Oracle Enterprise Manager 11g Grid Controlinstallation Oracle enterprise manager 11g Grid manage

What’s different from a local administration/Database handle installing are the presence of the Oracle administration service (OMS) and the management Agent. moreover, instead of seeing Database control in the internet browser/user interface, you see Grid handle. What’s no longer new or diverse – with a caveat - is the management Repository. When the use of commercial enterprise supervisor/Database control, the repository is put in within the database being created. When using commercial enterprise manager/Grid control, the repository can are living very nearly any place when it comes to being within one more Oracle database.

the first step in an installation is to create the administration repository. That’s fairly straightforward (and should be lined later), and isn’t too distinct from what you can be used to when the use of “emca” to create or recreate a repository. The 2nd step is to installation an Oracle WebLogic Server for the management provider, and the closing step is to installation an entire enterprise manager gadget together with an agent and an OMS.

what's in reality new for OEM free up 11g is the incorporation of Oracle WebLogic Server (WLS). BEA methods changed into the prior owner of WLS. WLS has the distinction of being the primary necessities based Java utility server. For what it’s price, WLS used to function by means of a license key, and your accessible facets have been driven or controlled through this file. BEA had an online license key migration function whereby you could get a brand new key for a new server (e.g., if you wanted to migrate an utility from one server to one more, hardware alternative, etc).

With Oracle business enterprise having bought BEA, that license key migration method is dead and long gone, so you probably have an current WLS installation, your improve path is going to include licensing of WLS from Oracle.

Yet yet another key point of Oracle using WebLogic Server can be present in application administration. WLS is the important thing to Fusion Middleware, and during this context, is THE net server going forward. There are other products where you nonetheless have a choice in terms of which J2EE compliant utility server which you can use. APEX, for example, presents a number of choices, but by means of and massive, it looks all roads (with admire to net servers aiding Oracle items) lead to WLS.

What they understand as commercial enterprise supervisor/Grid handle these days – with its user interface and the way it could actually support you centrally manage one or extra Oracle databases – will develop into (and is in the manner of becoming in other places) the net management interface for no longer best databases, but for a lot of different Oracle items. Put one more approach, any product involving Fusion is going to be managed by way of Oracle commercial enterprise supervisor. in accordance with an Oracle whitepaper, the expertise stack is going to offer “a complete conclusion to end monitoring and administration solution throughout the total spectrum of company transactions, with the ability to diagnose and remediate any issues at all tiers of the application stack.”

What’s in it for you to learn the way to installation and use the Grid handle version of enterprise manager? There are a couple of advantages, each with dazzling payoff in terms of making you extra effective. First, getting sensible on commercial enterprise supervisor Grid control has payoff in terms of being capable of manipulate numerous databases from one interface. The concept or theory of installation an agent, which is used to video display and file to a centralized administration server, is used in rather a couple of different items backyard the area of Oracle. you probably have experience with any of those different products, you’ll suppose right at home with Oracle’s version of this. there is a moderate to negligible hit on performance because of the presence of the agent, however that’s not any distinct than operating Database manage. if you're comfortable with the overhead of AWR on a local database, you won’t mind the presence of an agent.

2nd, and probably the largest reason to get on board with Grid control, is the exposure you’re going to get with WebLogic Server. Oracle utility Server and Oracle HTTP Server, let’s say, served their aim back within the day, but now they have some thing more desirable and extra robust. In a couple of trade reviews (going lower back a few years earlier than the acquisition by way of Oracle), WLS became the leading software server. Getting publicity to an incredible league product can’t be a bad issue.

Third, and finally, given the commentary of path in the white paper, loads of what you understand within the Grid control/database administration area is going to lift over into your ability to manage Oracle Fusion Middleware products. Already being regularly occurring with the person interface/seem-and-believe of Oracle’s internet-based mostly administration equipment will prevent time and power. which you can take what you know from setting up and configuring WLS on the database facet and immediately follow that adventure towards configuring and managing other items or tools (types and reviews, E-enterprise Suite’s Oracle utility manager, and many others.).

in the next article, I’ll cowl the installing of enterprise manager and reveal a way to use and configure brokers for databases installed on a windows 2003 server and on a server the use of Oracle commercial enterprise Linux (both of a good way to run as digital machines on the identical desktop).

Monitoring Oracle Database 11g R2 with Oracle Enterprise Manager | real questions and Pass4sure dumps

Simplify the monitoring of queries in Oracle Database with Oracle Enterprise Manager (OEM). Learn how to analyze query related activity and reach a definitive conclusion of database performance.

This document simplifies the monitoring of queries in Oracle Database with Oracle Enterprise Manager (OEM). The purpose of this paper is to show quickly how they can analyze query related activity and reach a definitive conclusion of Oracle's performance. Active Session History (ASH) is explored to show if the workload on Oracle is beyond its support limit. Query snapshot is explored to show greater detail and to allow us to guesstimate when a given query is likely to complete.


Most of us are familiar with a saying ‘If you do not know where you are going, any road will get you there’. The same thing goes with Oracle Database when it comes to monitoring or troubleshooting. One can spend hours or days without knowing what happened, if they do not focus on the situation at hand. You have probably also heard, "let us throw more CPU and hardware at the problem, all will work well". In general, this can be a valid assumption, but not always. Adding more horsepower to solve a system problem can result in more contention as CPU churns out more data, thereby choking the system. If you have an Oracle query problem, OEM is most likely the answer.

Oracle Enterprise Manager (OEM) is a single interface that greatly enhances their ability to monitor and diagnose queries. A few tools are included within OEM interface that allow us to look deeper to get a better snapshot at a particular query. It is important to know that OEM has changed from Oracle 10g to 11g. OEM query monitoring is straightforward in understanding what is happening at Oracle level. If one is monitoring at a low level, such as byte or block view, third party tools are available in the market, OEM is not the best option in this case.


Start your journey by logging into OEM. I assume that you have Oracle and OEM configured correctly, and everything works as expected. Since this is a web interface, anyone can click through various navigational links to study details. This is not challenging to most of us as they have sufficient database background. In my case, I am using an Oracle Database 11g R2 on a 4-node RAC with 256 Gig on each 24 core CPU, using high end 1 TB of cache at storage, in a DW environment. This is a ‘near’ production environment with high or even higher workload compared to real systems. Though configuration details are irrelevant, statistics that you notice in subsequent sections can be related back to this environment.

At the home page, you can quickly skim through a couple of important particulars.

OEM Home PageFigure 1

On the same page, towards the lower bottom, OEM displays high resource hitters with ADDM findings. These are sorted by total impact to the Oracle environment. Here are two such snapshots taken at different times.

OEM displays high resource hitters with ADDM findingsFigure 2

The snapshot above is quite different from the ADDM findings at a different time. As can be seen below, only two instances are experiencing these symptoms. You can click on the Findings link to see details, but since their focus is on queries, they will skip that part.

OEM Home Page - click on the Findings link to see details

Click on the Performance link on the top of the page, shown below for reference.

Click on the Performance linkFigure 3

This takes us to the next web page. This page has important particulars for monitoring and quick diagnosing across all Oracle instances. If you have not already done so, please spend some time on all sections of this web page. This knowledge is useful in many troubling circumstances. They can go back in time using View Data on the top right corner dropdown box.

My focus always goes first to Average Active Sessions (See Figure 4). This graph is placed appropriately at the center of the page, signifying the high importance of this graph. They first check to see if their system is within the workload. This graph shows a snapshot of the system workload, including what is contributing to performance delays. All factors are stacked together to show if their system is within the workload. Each value that is represented in this graph on the Y axis is derived from values Oracle uses internally. In other words, it is not easy for us to manually calculate the value of Y axis. X axis is time based, they can relate to this easily. This graph shows up to 160 at any time. Why each component (color portion) gets a certain value is not explained by Oracle. This value depends on various factors such as load on the system, CPU and memory utlization, etc. If all stacked factors are within an acceptable range, the graph should be below the red line. Reference A has further discussion on this topic based on extensive work carried by Kyle.

High workload scenario

For illustration purposes, I am using only two nodes effectively, through the creation of a service, yet their system shows the workload beyond the maximum CPU mark. Since their environment is a 4 node RAC, with only 2 nodes in use, that gives 2 x 24 CPU = 48 CPU. In other words, the load is excessively high and it should not cross beyond 48 points on this graph. Oracle arrives at these numbers through internal algorithms that closely related CPU usage and other resources.

the load is excessively high and it should not cross beyond 48 points on this graphFigure 4

In the following picture, the same RAC is shown with a different workload on the system. This is within workload limits.

the same RAC is shown within workload limitsFigure 5

Here is the same four node RAC, operating within its workload limits.

the same four node RAC, operating within its workload limitsFigure 6

We can also monitor other factors such as throughput, I/O activity, parallel execution at node level involving interconnect, services (for instance, 4 node RAC can be divided to support 2 nodes for batch service and other 2 nodes for ad hoc queries) and instance level monitoring. As mentioned above, they want to lead their journey to query monitoring.

monitor other factorsFigure 7

Please click on these links above (from OEM) to see corresponding activity. Reference B is a good source for this area.

Query Monitoring

Towards the bottom of the page, they notice the Query Monitoring link. Just to recap, after logging into OEM, click on the Performance tab to see this link. This link allows us to monitor all active queries, in addition to previously run queries.

the Query Monitoring link

The next screen is where all query details are presented in an easy to understand manner. One can drill down further to reach corresponding pages where additional information is presented. Note that they can either limit to the last five minutes or extend all the way to a day so that they can look at queries in those periods. Likewise, they can stop refresh or adjust refresh of query details. This comes in handy when the system is too busy with heavy ad hoc queries.

Monitored SQL ExecutionsFigure 8

Shown below is one entry in the SQL execution table in this window. Depending on the system load, there can be multiple queries.

one entry in the SQL execution table Figure 9

The above screenshot are the following values:

  • Query status is active, displayed with a green line halo.
  • It has been running for the past 10 hours.
  • Running on instance 4, SQL ID and user name indicated. If running on other instances or nodes, this is where it started.
  • Running with 24 parallel threads, using only one instance. That is, no inter node traffic, in a way.
  • Database time, IO requests, start & end time, and SQL text are indicated in this table.
  • Double clicking on SQL ID, in this case, 8bysvy84skdp3, takes us to their destination. One can certainly travel farther to explore and reach higher enlightenment. For their purpose, they are at their final stage.
  • Degree of Parallelism is set at 24 for this query, at resource manager level. Though you can set this parameter using dbms package commands through sqlplus, I find it very helpful to use the OEM web interface to change this.

    Simplified query plan

    This query does a simple join of four tables, one of which is a big fact table and the rest are dimension or lookup tables. Since all rows are used in all tables (there are corresponding matching rows for each row in the big fact table), it involves receiving data starting from the fact table. Here is a simple flow:

    simple query flowFigure 11

    Steps involved at a higher level:

  • Read from a table: Parallel processing by reading from that table, this is shown at leaf level.
  • Read from another table, if applicable -: Parallel reading with hash joins. This acts as input to the next iteration, if applicable.
  • Keep doing above until there are no more tables.
  • All of the above joins use hash joins, with final level sorting and grouping. Note that there is no WHERE condition for this query. As a general observation, hash joins are extremely popular with data appliances including Teradata. One advantage of the hash join is that typically no ordering or sorting is needed before the join takes place.

    A few important items to look at in this screen shot. Due to page limitations, not all steps in this query are visible.

  • Left column indicates that all operations are parallelized; this is indicated by icons on the left. Blue and orange indicates sender and receiver, based on Oracle parallel processing.
  • We know which step Oracle is processing by a green arrow point on the left and corresponding green flash on the right of most columns.
  • We know how long this query is expected to last based on estimated rows and actual rows columns. This is mostly accurate based on how up to date statistics are and how Oracle optimizer is gathering particulars in its interpretation.
  • Query is indicated in a reverse tree hierarchy. This query as explained above, does not contain a WHERE clause and involves hash joins.

    Oracle to release 86 security patches, including 18 for MySQL | real questions and Pass4sure dumps

    Oracle is preparing to ship 86 patches covering security vulnerabilities in a wide span of its products, with 18 of the fixes aimed at the MySQL database alone.

    Two of the MySQL vulnerabilities can be exploited by an attacker remotely without the need for a user name and password, according to a pre-release announcement posted on Oracle's website. At least one has a "base score" of 9.0 on the CVSS (Common Vulnerability Scoring System), which runs from 1 to 10, with 10 being the most dangerous.

    [ Andrew C. Oliver answers the question on everyone's mind: Which freaking database should I use? | Keep up with the latest approaches to managing information overload and compliance in InfoWorld's Enterprise Data Explosion Digital Spotlight. ]

    The patch batch, which is scheduled for Tuesday, also includes one fix for Oracle's flagship database, including versions 10g R2, 11g R, and 11gR2. While the vulnerability in question also has a CVSS base score of 9.0, it can't be exploited remotely without credentials, according to the announcement.

    But another five patches will be shipped for Oracle Database Mobile/Lite Server, and all of them are remotely exploitable without requiring authentication, Oracle said. This grouping's highest CVSS base score is 10.0, according to Oracle.

    Various components of Oracle Fusion Middleware, including WebLogic Server and Access Manager, will receive seven patches.

    Some 13 patches concern Oracle Enterprise Manager Grid Control. All are exploitable remotely without credentials.

    The remaining fixes set to ship Tuesday cover Oracle applications such as E-Business Suite and JD Edwards, as well as the Sun Storage Common Array Manager and Oracle's virtualization technology.

    Oracle's last patch release, which came in October, fixed 109 problems.
