The z/OS Batch Runtime is established by launching the Java™ program com.ibm.zos.batch.container.BCDBatchContainer with the proper configuration and environment settings that allows your PL/I, COBOL, and Java programs to be invoked with the correct arguments. The JZOS launcher, a component of the IBM® JDK for z/OS®, is used to establish the environment and pass control to z/OS Batch Runtime which, in turn, will launch your PL/I, COBOL, or Java program and provide necessary services. To facilitate the use of z/OS Batch Runtime, z/OS includes:

• Environment tailoring shell scripts: bcdconfig.sh and bcdconfigend.sh in /usr/lpp/bcp
• A JCL procedure to be invoked by batch jobs: BCDPROC in SYS1.PROCLIB
• A sample batch job to use BCDPROC: BCDBATCH in SYS1.SAMPLIB
