newsIBM DB2 Will goal Oracle Database developers
IBM this week announced a brand new edition of its flagship DB2 database with software so as to deliver compatibility with functions constructed for Oracle databases.
Embedded in IBM's imminent DB2 9.7, code-named "Cobra" and slated for unencumber in June, is application that gives compatibility with EnterpriseDB Corp.'s Postgres Plus advanced Server database, which helps all Oracle statistics kinds, SQL syntax, semantics and other applications built with Oracle PL/SQL stored techniques. Postgres superior Server is constructed on the open source PostgreSQL database.
"The set of technologies they now have added will support developers of customized functions and packaged functions installation to DB2," spoke of Bernie Spang, director of approach, analytics and information management for IBM's application neighborhood.
For IBM, or not it's the primary time the business has licensed know-how from a provider of open source database application, although EnterpriseDB founder Andy Astor said the software embedded in DB2 is in accordance with proprietary code.
"this is now not an open source play," Astor said. "every little thing else they do is open supply however that is likely one of the techniques they make their funds, by using selling that compatibility know-how both to providers like IBM, in this case, and to users in the sort of Postgres Plus superior Server."
EnterpriseDB features to a couple of shoppers together with FTD and Sony on-line leisure that have migrated purposes developed for Oracle databases to Postgres Plus. The deal with IBM "offers them with confirmed performance for enabling compatibility between DB2 and applications written for Oracle," noted 451 neighborhood analyst Matthew Aslett in an e-mail.
"Database migrations are complicated, time-drinking, costly and rare, so any functionality that makes the system more straightforward goes to be welcomed by means of those organizations that are prepared to make the soar," he delivered.
The licensing pact is the first by means of EnterpriseDB, however Astor pointed out others are being negotiated.
IBM is hoping the circulation will encourage greater customers emigrate to its InfoSphere Warehouse 9.7 commercial enterprise version, a data-cleaning and business analytics platform in line with DB2 and know-how IBM bought from Cognos.
the brand new unencumber is centered at bringing records mining, analytics and cubing to departments of businesses and smaller corporations, Spang noted. also new in DB2 is support for performing simultaneous transactions across XML and relational statistics.

DB2 DBAs have a number of graphical-based tools they can use to manage and administer DB2 data servers. Alternatively, a DBA can also use a script-based approach to administer the data environment using the DB2 tools to create and schedule the scripts. This section briefly details the main graphical tools available with DB2.Control Center
The Control Center is the central point of administration for DB2. The Control Center provides DBAs with the tools necessary to perform typical database administration tasks. It allows easy access to other server administration tools, gives a clear overview of the entire system, enables remote database management, and provides step-by-step assistance for complex tasks.
The All Systems object represents both local and remote data servers. To display all the DB2 systems that your system knows about, expand the object tree by clicking on the plus sign (+) next to All Systems. In Figure 1-17, you can see a DB2 data server called PAULZ contains a DB2 instance called DB2, in which the database TEST is located.
When you highlight an object, details about that object are shown in the Contents Pane.
The main components of the Control Center are:
The Control Center also comes with personality control that you can use to adjust the view and functions available from the Control Center's tree view of your data server. For example, you can limit the Object Pain view to show just Tables or Views, as well as limit the actions you can perform from the context-sensitive right-click menu options. You can customize your Control Center personalities using Tools → Tools Settings → Customize Control Center.DB2 Replication Center
The DB2 Replication Center is a graphical tool that allows DBAs to quickly set up and administer all forms of data replication, including the options offered by WebSphere Replication Server. The main functions in setting up a replication environment can be performed with this tool, including:
You can use the Replication Center to set up all kinds of DB2 replications, as shown in Figure 1-18.Other Tools Available from the Control Center
By using the Control Center tool bar, you can access a host of other graphical administration tools to help you manage and administer databases in your environment:
The DB2 Health Center (Figure 1-19) is the central point of information with respect to managing the health of your DB2 system. When you install a DB2 9 data server, out of the box it automatically monitors 27 (and counting) health indicators that proactively monitor the health of your data server. The DB2 Health Center implements a management-by-exception model whereby alerts are surfaced when Warning or Alarm thresholds are breached. Although DB2 configures these thresholds for you out of the box, you can configure them yourself as well as specify scripted actions to occur in the event of an alert.
You don't have to use the DB2 Health Center to work with DB2's health information or set triggered actions to occur on threshold breaches. You can use a number of SQL-based user defined functions to work with the DB2 health facilities from the command line.
The DB2 Health Center can monitor indicators across the following health categories:
The DB2 Health Center's graphical user interface allows DBAs to select database objects and drill down on its details, current alerts, and the recommended actions. The DB2 Health Center also includes the DB2 Recommendation Advisor that can be used to walk through potential fixes to alerts and alarms raised in this facility.DB2 Configuration Assistant
The DB2 Configuration Assistant (DB2 CA) lets you maintain a list of databases to which your applications can connect, as well as manage and administer those connections. It is mostly used for client connectivity configuration. You can start the DB2 CA by entering the db2ca command from your operating system's command-line shell or from the DB2 folder in the Start menu. Some of the functions available in the DB2 CA are shown in Figure 1-20.
Using the DB2 CA, you can work with existing databases, add new ones, bind applications, set client configuration and registry parameters (also shown in Figure 1-20), test connectivity, and import and export configuration profiles.
The DB2 CA's graphical interface makes these complex tasks easier by means of the following:
The DB2 CA's Discovery feature is very useful because it allows you to add a database connection without having to know the syntax of DB2 CATALOG NODE and DB2 CATALOG DATABASE commands, or even the location information of the remote data server.
As you can see in Figure 1-20, the DB2 CA displays a list of the databases to which your applications can connect from the workstation where it was started. Each database is identified first by its database alias, then by its name. You can use the Change Database Wizard to alter the information associated with databases in this list. The CA also has an Advanced view, which uses a notebook to organize connection information by the following objects:
DB2 comes with a set of Wizards and Advisors to help you with day-to-day tasks. Wizards can be very useful to both novice and expert DB2 users. Wizards help you complete specific tasks by taking you through each task one step at a time and recommending settings where applicable. Wizards are available through both the Control Center and the Configuration Assistant.
There are wizards for adding a database to your system, creating a database, backing up and restoring a database, creating tables, creating table spaces, configuring two-phase commit environments, configuring database logging, updating your documentation, setting up a High-Availability Disaster Recovery (HADR) pair, tuning your performance, and more.
Figure 1-21 shows a portion of the Create Database wizard in DB2 9.
Advisors are special types of wizards that do more than provide assistance in completing a task. Traditional wizards take you step-by-step through a task, simplifying the experience by asking important questions or generating the complex command syntax for the action you want to perform. When a wizard has more intelligence than just task completion and can offer advisory-type functions, DB2 calls them advisors. They operate just like wizards but are intelligent enough (having some pretty complex algorithms) to generate advice based on input factors such as workload or statistics. Advisors help you with more complex activities, such as tuning tasks, by gathering information and recommending options that you may not have considered. You can then accept or reject the advisor's advice. You can call advisors from context menus in the DB2 administration tools, from APIs, and the command-line interface.
Advisors are part of the IBM autonomic computing effort, which aims to make software and hardware more SMART (self-managing and resource tuning). There are three main advisors in DB2 9: the DB2 Configuration Advisor, the DB2 Recommendation Advisor, and the DB2 Design Advisor.
The DB2 Configuration Advisor is automatically run for you whenever you create a new database in DB2 9. It can configure up to 35 instance-level and database-level parameters for you based on responses to high-level questions that describe the data server environment and type of application you plan to support.
The DB2 Recommendation Advisor, as previously mentioned, is closely associated with the DB2 Health Center and is used to offer solutions to raised alerts and alarm breeches in this facility.
The DB2 Design Advisor is used to identify objects such as materialized query tables (MQTs), multidimensional clustering tables (MDCs), indexes, and partitioning keys that could optimize a given SQL workload. The DB2 Design Advisor can also identify indexes that aren't needed as well (shown in Figure 1-22).
When using this advisor it's important to note that the suggestions it provides are based on a submitted workload. If you've left out significant portions of a workload, the answer will not reflect the impact of the missing workload. In addition, the DB2 Design Advisor gives you the ability to heavily weight SQL statements in a submitted workload over others, giving you more control with respect to how the DB2 Design Advisor will recommend the creation of performance objects with respect to your real workload characteristics.The DB2 Command Line Processor
The DB2 Command Line Processor (DB2 CLP) is a component common to all DB2 products. It is a text-based application that can be used to issue interactive SQL statements or DB2 commands. For example, you can create a database, catalog a database, and issue dynamic SQL statements all from the DB2 CLP. Your DB2 statements and commands can also be placed in a file and executed in a batch environment, or they can be entered in interactive mode.
Figure 1-23 shows an example of using the DB2 CLP to enter DB2 commands. The DB2 CLP operates in an "interactive" mode and therefore does not require the db2 prefix associated with entering DB2 commands.
The DB2 CLP is provided with all DB2 and DB2 Connect products. All SQL statements issued from the DB2 CLP are dynamically prepared and executed on the data server. The output, or result, of the SQL query is displayed on the screen by default. All of the DB2 commands that you can enter in the DB2 CLP are documented in the DB2 Command Reference. You learn more about the DB2 CLP and how to enter DB2 commands from an operating system's native CLP in Chapter 2.Visual Explain
Other graphical tools can be used for tuning or monitoring performance. Visual Explain is a graphical utility that provides a visual representation of the access plan that DB2 uses to execute an SQL statement.
Visual Explain can be invoked from the Control Center, the DB2 CLP (though the output in textual and not graphical), the DB2 DWB, or from the Command Editor.
Figure 1-24 shows the type of information that is displayed. You can see that the query is accessing two tables and an approximation of the cost of each step of this query is also provided in the Visual Explain output. The estimated query costs represent the complexity and resource usage expected for a given SQL query. There are many more details and features provided in Visual Explain under the Statement menu option.
Figure 1-24 Using Visual Explain to look at how your query is run by DB2DB2 Query Patroller
DB2 Query Patroller (DB2 QP) is an add-on product that can be used to control and monitor query execution, as well as work with queries to prioritize and schedule user queries based on user profiles and cost analysis performed on each query. Large queries can be put on hold and scheduled for a later time during off-peak hours. Queries with high priority (based on user profiles) are promoted to the top of the schedule.
In addition, DB2 QP monitors resource utilization statistics. DB2 QP can use this information to determine the load distribution of the system, which can allow it to balance the number of users allowed to submit queries at any given time.
DB2 QP greatly improves the scalability of a data warehouse by allowing hundreds of users to safely submit queries on multi-terabyte class data servers. Its components span the distributed environment to better manage and control all aspects of query submission. The services provided by this product act as an agent on behalf of the end user. It prioritizes and schedules queries so that query completion is more predictable and system resources are more efficiently utilized. DB2 QP obtains query costs from the DB2 Optimizer and then schedules them for execution—this means that DB2 QP is tightly integrated with DB2 engine.
DB2 QP can also be used to set individual user and user class priorities as well as user query limits. This enables the data warehouse to deliver the needed results to its most important users as quickly as possible. If desired, an end user can choose to receive notice of scheduled query completion through e-mail.
Finally, as discussed earlier in this chapter, DB2 QP offers the ability to perform charge back for data server usage to specific departments identified by accounting strings on the connection context. For example, if marketing is using the data warehouse three times more than accounting, they should pay three times the charge back. In Figure 1-25, you can see one of many canned reports that come with DB2 QP. This one shows the number of statements run by month. You can drill down into this view to the minute and second interval, as well as access a host of other reports such as average execution time, average wait time, average queue time, and more.
Figure 1-25 Performing charge back with DB2 Query PatrollerDatabase Monitoring Tools
The Snapshot Monitor captures database information at specific intervals. The interval time and data represented in the performance graph can be configured. The Snapshot Monitor can help analyze performance problems, tune SQL statements, and identify exception conditions based on limits or thresholds.
The Event Monitor captures database activity events as defined by the event monitor definition. Event Monitor records are usually stored on disk and then analyzed after the data has been captured. The Event Analyzer graphical tool provided with DB2 can be used to analyze the captured data.
The Activity Monitor help you improve the efficiency of database performance monitoring, problem determination, and resolution. By tracking a set of predefined monitor data, the Activity Monitor allows you to quickly locate the cause of a problem. You can then take direct action to resolve the problem or invoke another tool for further investigation. The Activity Monitor can help you monitor application performance, application concurrency, resource consumption, and SQL statement usage. It can also assist you in diagnosing performance problems such as lock waiting situations (as shown in Figure 1-26), and in tuning queries for optimal utilization of the data server's resources.
Figure 1-26 Using the Activity Monitor to diagnose a lock waiting problemThe DB2 Storage Management Tool
The DB2 Storage Management Tool can be used to monitor the storage state of a database. You can use this facility to take storage snapshots for a database or a table space. When a database or snapshot is taken, statistical information is collected for all the table spaces defined in the given database (you can also snapshot at the table space level).
The Storage Management Tool enables you to set thresholds for data skew, space usage, and index cluster ratio. If a target object exceeds a specified threshold, the icons beside the object and its parent object in the Storage Management view are marked with a warning flag or an alarm flag—similar to the DB2 Health Center.
You can see in Figure 1-27 that the SYSCATSPACE table space is running out of space as it's 98 percent used.

There are two kinds of tools for DB2: those that are free and those that are add-ons that can be purchased separately. The free tools come as part of a DB2 installation and can be launched from the Control Center, the Configuration Assistant, or on their own. A separate set of purchasable tools are available to help ease a DBA's task of managing and recovering data, tuning performance, and more. The DB2 suite of these tools includes (www-306.ibm.com/software/data/tools/mptools.html):

IBM Data Science Experience provides an environment that brings together all of a data scientist’s tools into one location. It includes the most popular Open Source tools and IBM value-add functionality with integration of community and social features to make data scientists more successful.
A wide variety of cloud data sources are easily connected to DSX, or a user could upload data from DB2 on z/OS (by creating a copy) into the environment. However, the ability to access to data in-place on the system of record, has great appeal.
In this guide, I will outline the steps needed to configure DSX to access an on-prem DB2 for z/OS database using JDBC and provide the ability to utilize RStudio to perform advanced analytics operations on this data.
Here is an outline of the steps they will go through in the guide to set up the DSX environment for DB2 for z/OS connectivity:
(Note: The screenshots in this tutorial are from a Mac OSX environment running Firefox. If you are running from Windows or Linux, there may some differences in the appearance of the native dialogs and browser interfaces.)
Once setup with your account, click on the DSX Logo at the top of your screen, and this will take you to the main Community page. Once there, if you click the far left drop-down menu, you will see your project options, including RStudio. Click on the the RStudio option, and this will open up your RStudio instance.
If you have opened DSX RStudio before, the instance opened will have retained any history or enviroment settings that you had saved/autosaved from before. If you are familiar with RStudio and have used a native version of RStudio on Windows/Mac OSX, it will look exactly the same. The only difference is that the underlying infrastucture is running in a Bluemix virtual machine. There is limited access to the underlying operating system, but they can access the filesystem to upload the JDBC driver and license file and configure the connection for DB2 for z/OS.
The RStudio interface should look similar to what is shown below……
(For a complete guide to using RStudio, please see the documentation linked to in the ‘Help’ Section)
Next, they will confirm that the correct packages are installed/loaded that enable JDBC access to their on-prem database.
In the bottom right panel of the RStudio desktop you will see the ‘Packages’ tab, and within that is an ‘Install’ tab. If you click “Install”, you will get a dialog box that allows you to load the required packages from the CRAN repo. You will need to install ‘RJDBC’. If the ‘Install dependencies’ box is checked, you will also be installing ‘rJava’ and ‘DBI’ (which load automatically). Once you install these packages, you should see them in the User Library. If they are unchecked, please check them, and they will be enabled in the environment.
Next, they will need to upload the appropriate DB2 for z/OS data server driver .jar files to the DSX environment. The files they will need are: db2jcc.jar and db2jcc_license_cisuz.jar
If you already have a licensed version of DB2 Connect installed, these driver files are already available on one of your existing client environment setups. Ask your DB2 system administrator for the location of these files in your client environment.
This guide is based on DB2Connect Version 11.1 for Linux, Unix and Windows (client) and DB2 for z/OS Unlimited Edition (server). If you are not currently licensed for DB2Connect, see the Appendix at the end of this guide for instructions on how to obtain the correct data server drivers and license files that are required.
From the RStudio desktop (shown above), go to the lower right panel again, to the “Files” section. Then, click “Upload” and you will get a dialog box that allows you to browse your local file system to upload the driver files. For both db2jcc.jar and db2jcc_license_cisuz.jar, upload these to the current directory of your DSX/RStudio environment.Connecting to the z Server over TCPIP — Secure Gateway
With the JDBC driver files in place, they now need to configure access to the server which is running the DB2 for z/OS instance. The assumption for most IBM customers is that their target z server is running on a secure internal network, which is accessed externally through a VPN or from an internal private network access point. If this is the case, you will also need to set up a Bluemix Secure Gateway, that will allow the Bluemix/DSX cloud app to access your z server through a firewall, using the same VPN/internal network acces point that you use for other client connections from a desktop.
For more general information on Bluemix Secure Gateways, please go to: https://console.ng.bluemix.net/docs/services/SecureGateway/secure_gateway.html
If you do not need to configure a Secure Gateway, you can skip to the “Connecting to DB2/zOS with JDBC” section.
To configure the secure gateway, please go to https://console.ng.bluemix.net/dashboard/services/, log in to Bluemix with the same credentials you are using for DSX, and then use the drop-down menu on the left to go to the ‘Services’ and then ‘Dashboard’ menu.
Once within the Services dashboard, click the “Create Service +” button.
Next, they will go to “Integrate” and then choose the “Secure Gateway” service from the menu.
Leave the service “Unbound” and click “Create”.
And, then “+ Add Gateway’
Choose a name for your gateway, uncheck both of the boxes listed, and then click “Add Gateway”.
Now, they can setup the destination details, and the client. Click on the gateway.
Then click on “+ Add Destination”.
Choose “On-Premises” and click Next.
On the next screen add your host name/IP , and the DB Port of your DB2z Subsystem. Click ‘Next’
Then, select TCP protocol on the next screen, and click “Next” again.
The next screen setting is related to server side authentication. If you typically connect with just a user and password, then choose “None”. If you are not sure whether or not your server requires additional authentication, ask your System Administrator, and you can change this later. Click ‘Next’.
You can skip over the next setting, unless you want to privatize the IP address and port or your connection. Click ‘Next’.
To complete the destination settings for the back-end server, they just need to give a name for their connection. Choose a name for your destination that describes the DB2 Subsystem you are connecting to, and then click “Finish”.
Now let’s install the client for their secure gateway. Choose “+ Add Clients”
Choose your preferred method of hosting the gateway client. For this demonstration, they will be using IBM Installer — Mac OSX version on a laptop that has a VPN connection to access an on-prem z server. The details for different OS installs and Using Docker or IBM DataPower are covered in detail in the online instructions. For specific install details, See the “Bluemix Documentation” link.
At this time, copy the Gateway ID, for input later into the gateway client command-line interface.
After Downloading the client, double-clicking the image, you might have to go to your ‘Finder’ to see the mount point for the image.
Click on the mount-point and then drag the ‘ibm’ folder into the Applications Folder.
Now, they can go into the ‘IBM’ folder within Applicatons, and double-click to run the segw.command to open the CLI for the gateway.
Enter the gateway ID you copied earlier, and then enter ‘none’ for the security token.
Next, note the web address of the gateway interface — localhost:9003/dashboard Enter that web address in your web browser.
Below, they see the gateway web UI. You can see all the details of your secure gateway from this interface. There is one more setting, for the access control list. Please click “Access Control List”, and then enter your destination hostname/IP and port once again.
Below, once you have added the host/IP and port, you can close the browser window, or minimize it.
We are almost done. The Secure Gateway config is complete.
Now they will return to the main Secure Gateway dashboard to copy the cloud hostname/port for the gateway. It will be used for the JDBC connection string in DSX/RStudio. From the Services Dashboard, click on the gateway you created.
On this screen, click on the ‘settings gear’ of the destination server connection details. A dialog box will open.
Copy the ‘Cloud Host : Port’ address to use in your JDBC connection in DSX/RStudio.
Return to the RStudio desktop, and they can setup the JDBC driver and run a query.Connecting to DB2/zOS with JDBC
In the RStudio desktop, they are now ready to enter the JDBC commands at the console prompt to setup the connection to their DB2 for z/OS database. Make sure the RJDBC, DBI, and rJava packages have loaded.
Also, at this time, make sure you are running any VPN connection that is normally required to access your backend system from a desktop client.
Enter the following commands in the RStudio console, noting the results you get for the classpath display:
.jinit() .jclassPath() .jaddClassPath("/home/rstudio/db2jcc_license_cisuz.jar") .jclassPath() drv <- JDBC("com.ibm.db2.jcc.DB2Driver","/home <br> /rstudio/db2jcc.jar") .jclassPath()
(* note the addition of the license file….its position in the classpath is important *)
