When shared memory is initialized

The VPCLASS configuration parameter specifies the number of virtual processors to initialize for a given virtual-processor class. The JVP option of VPCLASS specifies the number of Java virtual processors that the database server should start.

This parameter is required to execute Java UDRs.

Set this option as follows, where number is the number of Java virtual processors:

VPCLASS JVP,num=number

The default value of range is 1. If you set the number of JVPs to zero (0), or if there is no VPCLASS parameter for the JVP class, execution of Java UDRs is disabled.

If you have not correctly installed and configured the software for Java in the server, the JVP fails to start when you start the database server. However, the database server itself continues to initialize normally. The main database log file contains a message that indicates the cause of the JVP failure.
