Language Environment runtime options

The JZOS batch launchers are built to specify Language Environment® runtime options that are designed to match their Java™ command-line launcher counterparts.

Changes to these Language Environment runtime options must be made before running the batch launcher. The following example demonstrates how to generate a storage report when the application exits:
//jobname JOB ...
//stepname EXEC PROC=JVMPRC16,
//JAVACLS=’com.ibm.jzos.sample.HelloWorld’,
//LEPARM=’RPTOPTS(ON),RPTSTG(ON)’
//STDENV DD *
...
//

For information about tuning the Java virtual machine, see Performance tuning.

You can use the CEEOPTS DD statement to specify an input file that contains Language Environment runtime options.
