Grant Management During a Database Upgrade

When upgrading a Db2 for z/OS database that is configured with both an administrator ID and a user ID, CES will automatically execute grant statements to ensure the user ID has the required permissions for all tables and views in the database.


Software and Hardware Requirements

For Topaz for Java Performance software and hardware requirements, refer to the Compuware Web Products Installation and Configuration Guide on the Compuware Support Center website at https://go.compuware.com.


Technical Notes

  A Google Chrome security update prohibits viewing of WebHelp when the help is deployed locally from a file server (as opposed to a Web server). Attempting to view locally deployed help displays a blank help window. Compuware suggests that online help be viewed using Internet Explorer. Alternatively, Chrome's security feature can be turned off by launching Chrome with the command line option --allow-file-access-from-files. This method should only be used when opening local WebHelp that you trust.

  Topaz for Java Performance and Compuware Enterprise Services (CES) must be at the exact same release level -- for example, Topaz for Java Performance and CES Release 19.01.01.

  If you are performing an upgrade installation of Topaz for Java Performance, be sure to do the following in your installation environment before beginning the upgrade:

-- For z/OS UNIX, stop the CES started task.

-- For Linux, stop the CES daemon.

-- For Windows, stop the CES Service.

  During a CES and Topaz for Java Performance installation, the user's specified JDK must be 64-bit.


Known Issues

  When installing CES on Windows, you may encounter an error referring to the Java VM. This is a problem with InstallAnywhere and Java 8. It can be resolved by removing the following entry from the Path variable:

C:\ProgramData\Oracle\Java\javapath

The Path variable is accessed from:

Control Panel>System>Advanced System Settings>Environment Variables>System Variables

  If you specify a temporary directory smaller than that which is required for installation, you may be presented with a message indicating that your evaluation period has expired. You can reallocate space and restart the installation process.
