DB2 administration server (DAS) Java virtual computer setup - IBM DB2 9.7 for Linux, UNIX, and Windows

The jdk_path configuration parameter specifies the directory under which the IBM® Software Developer's Kit (SDK) for Java to be used for running DB2® administration server functions is installed. The environment variables used by the Java interpreter are computed from the value of this parameter.

About this task

The scheduler requires a Java virtual computer (JVM) in order to use the tools catalog database. It is necessary to have this setup before the scheduler can be successfully started.

There is no default value for this parameter when working with UNIX platforms. You should specify a value for this parameter when you install the IBM Software Developer's Kit (SDK) for Java.

The IBM Software Developer's Kit (SDK) for Java on Windows is installed under %DB2PATH%\java\jdk (which is the default value for this parameter on Windows platforms). This should already be specified to the DAS. You can verify the value for jdk_path using:

   db2 get admin cfg

This command displays the values of the DB2 administration server configuration file where jdk_path is one of the configuration parameters. The parameter can be set, if necessary, using:

   db2 update admin cfg using jdk_path 'C:\Program Files\IBM\SQLLIB'

This assumes that the DB2 database manager is installed under 'C:\Program Files\IBM\SQLLIB'.

The IBM Software Developer's Kit (SDK) for Java on AIX® is installed under /usr⁄java130. The parameter can be set, if necessary, using:

   db2 update admin cfg using jdk_path /usr/java130

Note: If you are creating or using a tools catalog against a 64-bit instance on one of the platforms that supports both 32- and 64-bit instances (AIX, Sun, or HP-UX) use the jdk_64_path configuration parameter instead of the jdk_path parameter. This configuration parameter specifies the directory under which the 64-bit version of the IBM Software Develop's Kit (SDK) for Java is installed.
