Remarks

This option lets you specify options that the database server uses when launching the Java VM specified by the java_location option. These additional options can be used to set up the Java VM for debugging purposes or to run as a service on Unix platforms. Sometimes additional options are required to use the Java VM in 64-bit mode instead of 32-bit mode.

Example

The following example uses the java_vm_options option to keep the Java VM running on Unix when the database server is started as a service and the user must log out:

SET OPTION PUBLIC.java_vm_options = '-Xrs';

The following example instructs the Java VM to use 64-bit mode on HP-UX:

SET OPTION PUBLIC.java_vm_options = '-d64';
