Introduction to DB2 10
The release of IBM DB2 10 for Linux, UNIX, and Windows introduces new features and enhancements focusing on lowering the total cost of ownership, business-critical reliability, and performance. With multiple editions available, from the no-charge Express-C to the top of the line Advanced Enterprise Edition, there is a DB2 product suitable for every business.
A look at the new features
One of the features introduced in DB2 10 that is geared toward reducing overall operational costs is multi-temperature data management. Multi-temperature storage allows you to designate fast (more expensive) storage options for your "hot" data, and slower (less expensive) storage for your "cold" data. In addition to this new feature in DB2 10, there are numerous enhancements to existing features, such as adaptive compression, which offers improved compression ratios and allows for more data in memory, thereby improving performance.
DB2 10 introduces several new features and enhancements to make the life of developers a bit easier. For example, SQL compatibility enhancements mean that applications written for competitive database systems require very few changes to run on DB2. Other enhancements include DB2 Graph Store for rapid development of applications, row and column access control to provide fine-grained access control to tables, and temporal capabilities with standardized SQL syntax.
To ensure reliability of data, DB2 10 includes enhancements to DB2 pureScale, DB2 Workload Management, and HADR.

Overview of DB2 virtual appliances
What is it, and why should I use it?
A virtual appliance is a pre-configured virtual server environment that greatly minimizes the work required for you to get up and running. There is no need to install an operating system, install software, and perform configuration of the software within the environment. It is pre-configured and ready-to-go. The IBM DB2 Enterprise 10.1 Trial Virtual Appliance can be run either locally on the host computer via VMware Workstation/Player, or remotely on a VMware vSphere environment. Upon initial boot of the appliance, you will need to provide secure passwords for the operating system and DB2 users, and optionally configure the network and time zone of the server. The IBM DB2 Trial Virtual Appliance features DB2 Enterprise 10.1, and an assortment of development and educational tools that are used to do the following.
- Alleviate application installation, configuration, and integration tasks.
- Test new features in DB2 10.1 with included tutorials and demonstrations.
- Develop new applications.
- Create DB2 demonstrations and presentations.
- Develop and test DB2 applications.
- Develop and deploy solutions.
Deploying the IBM DB2 Virtual Appliance starts a SUSE Linux Enterprise Server 11 instance that is configured with DB2 Enterprise 10.1. Table 1 shows you an overview of the software components that are installed in the virtual appliance, as well as driver versions that are applied as part of the deployment.

Table 2. Hardware requirements for DB2 Trial Virtual Appliances.
|Memory on host machine||Minimum: 1.5 GB|
|Disk space on host machine||Minimum: 8.0 GB|
The image is designed to run in VMware Workstation 6.5.x and VMware Player 3.x or later. You can also choose to convert the image to OVF format which is designed to run in all VMware products. You may download the VMware software from the VMware website (see the Resources section for a link).
Get it, extract it, deploy it, and run it on VMware Workstation/Player
To run the virtual appliance (either 32-bit or 64-bit), perform the following steps.
- Download the DB2 Trial Virtual Appliances (see the Resources section for a link).
- Copy the self-extracting package into your desired directory. The
self-extracting package name should be in the form of the following.
- Extract the contents of the package to the desired directory.
- On Linux you can use the following command:
unrar x DB2_ESE_10.1_trial_VA_<bitness>bit.exe(This requires an unrar utility that is supported on your platform).
- On Microsoft Windows you can extract the contents by double-clicking the file and following the prompts.
- On Linux you can use the following command:
- Open VMware on your host operating system.
- Open the VMware image that was extracted in the previous step. You may do this by clicking File > Open, and then browsing to the directory where the files were extracted from within VMware Workstation.
- Start the image by clicking the Power or Play button.
Converting to Open Virtualized Format (OVF) and deploying on an ESX server
To convert the Virtual Appliance to an Open Virtualized Format, you must first download and install the OVF Tool from VMware (see the Resources for a link). Once installed, perform either of the following steps.
- To convert the Virtual Appliance in VMX format to an OVF package, use
the following command:
Listing 1. Converting a VMX to an OVF
ovftool DB2_ESE_10.1_trial_VA_<bitness>bit.vmx DB2_ESE_10.1_trial_VA_<bitness>bit.ovf
- To convert the Virtual Appliance in VMX format to an OVA file, use the
Listing 2. Converting a VMX to an OVA
ovftool DB2_ESE_10.1_trial_VA_<bitness>bit.vmx DB2_ESE_10.1_trial_VA_<bitness>bit.ova
To deploy and run the Virtual Appliance on an ESX server, perform the following steps.
- Open the vSphere Client. From the menu bar, click File > Deploy OVF Template. The Deploy OVF Template wizard appears.
- Once you have converted to OVF or OVA, choose Deploy from File, then click Browse and navigate to the directory on your system that holds the files (make sure to select the correct file type of either OVF or OVA). Otherwise you can deploy the DB2 Virtual Appliance directly from an URL, choosing the option Deploy from URL and type the URL to the OVF file. Click Next to continue.
- The details of the DB2 Virtual Appliance will be displayed. Click Next after reviewing.
- (Optional). You can choose to edit the name of the virtual appliance as it will appear in your vSphere Client. Click Next to continue.
- Select the resource pool and datastore in which to store the DB2 Virtual Appliance, then click Next to continue.
- Review the deployment settings in the last screen of this wizard to ensure the deployment task is correct. Click Finish to start the deployment of the DB2 Virtual Appliance.
Configuring the virtual appliance for the first time
Once the DB2 10.1 Enterprise Trial Virtual Appliance is powered on for the
first time, it will load up the default operating system and configure the
secondary disk for database storage disk. It will be located on
system. No action is required.
When the SUSE boot-up process is complete, you will be greeted with the following set of configuration screens that you need to complete for the customization of the virtual machine.
- A Language & Keyboard screen allows you to customize the display language and keyboard layout for the locale of your choice. It defaults to English locale with a US keyboard layout. These settings can be changed by using the drop-down menus. If you change the language, then it will automatically detect a new keyboard layout, which of course can be changed as well.
- A Welcome screen is shown that explains that there are a few configuration steps to be taken before the virtual image is ready for use.
- The SUSE Linux Enterprise Server 11 SP2 license agreement will be presented. You must read and accept the license agreement; otherwise the virtual machine will halt immediately.
- The DB2 10.1 Enterprise Trial Virtual Appliance license agreement will be shown as well. Again, you must read and accept the license terms and conditions to proceed with using the virtual machine.
- You will be asked if you would like to choose a hostname for the system. The default hostname can be accepted or can be changed at this configuration screen.
- Next, the Network Configuration screen will be shown. It defaults to DHCP IP address. However, it is recommended that a static IP address is chosen at this configuration screen. In order to configure a static IP address, click the Change button at the bottom of the screen to change the default configuration.
- The virtual image will next let you choose a different time zone. The default setting is Canada/Toronto. Using the available menus, the time zone can be changed to match your location.
- Next, you must choose a secure password for the root user. Click Next to continue.
- As a final step in the configuration, you must choose a password for the DB2 instance and fenced users, as well as the Workload Multi-user Driver (WMD) user. Once chosen, click Next to complete the configuration of the virtual machine.
This completes the configuration of the DB2 10.1 Enterprise Trial Virtual Appliance. The virtual appliance will take a few minutes to complete the boot up process and you will be ready to try out all the new features in DB2 10.1.
Note: It is highly recommended that you install the VMware Tools version that comes with your VMware product after the DB2 10.1 Virtual Appliance has been fully configured. VMware Tools bring in many benefits for the use of any virtual environment, including better clock synchronization with the host system, improved file movement between the host and guest OS (if applicable), and improved GUI responsiveness. For more information about VMware Tools, please refer to your VMware product manual.
Adobe Flash Player is not distributed with the virtual appliances, therefore, you will either need to download and install it manually or use a remote browser to access any web pages requiring Adobe Flash Player technology.
Tools for your use
The deployed DB2 Virtual Appliance includes several tools that have been included to ease some of the regular system tasks, such as stopping and starting the DB2 database manager as part of the SUSE boot sequence, as well as stopping and starting the WMD deamon during reboots and shutdowns of the machine.
The DB2 init script that was written for SUSE can be invoked by the root user at any time to stop/start/restart the DB2 database manager as shown in Listings 3 through 6.
Listing 3. Retrieve status of DB2 database manager
# rcdb2 status Instance db2inst1 (50001) (/opt/ibm/db2/V10.1): running
Listing 4. Stop DB2 database manager
# rcdb2 stop Stopping instance db2inst1 (50001) (/opt/ibm/db2/V10.1): done
Listing 5. Start DB2 database manager
# rcdb2 start Starting instance db2inst1 (50001) (/opt/ibm/db2/V10.1): done Activating database SAMPLE for db2inst1 done
Listing 6. Restart DB2 database manager
# rcdb2 restart Stopping instance db2inst1 (50001) (/opt/ibm/db2/V10.1): done Starting instance db2inst1 (50001) (/opt/ibm/db2/V10.1): done Activating database SAMPLE for db2inst1 done
The Workload Multi-user Driver (WMD) deamon init script written for SUSE works a similar way. It is used to start/stop/restart the service that controls the deamon, which in turn is used to run sample workloads that can be monitored via the Technology Explorer for IBM DB2, as shown in Listings 7 through 10.
Listing 7. Retrieve status of WMD deamon
# rcwmd status Status of Workload Multiuser Driver deamon ... running
Listing 8. Stop WMD deamon
# rcwmd stop Stopping the Workload Multiuser Driver ... done
Listing 9. Start WMD deamon
# rcwmd start Starting the Workload Multiuser Driver with user wmd done
Listing 10. Restart WMD deamon
# rcwmd restart Stopping the Workload Multiuser Driver ... done Starting the Workload Multiuser Driver with user wmd done
These tasks can be performed when needed, but you don't need to manually stop or start DB2 or WMD when the system powers on or shuts down. Those services will be taken care of when the proper Linux reboot or shutdown procedures are used.
