Batch, UNIX System Services, and Java considerations

Batch: To launch Encryption Facility for OpenPGP from batch, IBM® provides the IBM JZOS Batch Toolkit for z/OS® (JZOS). For sample code, see Sample JCL and code. For complete information about setting up and using Java™ and the SDK for z/OS and for JZOS, see the z/OS Java home page.
UNIX Systems Services: Use UNIX System Services with Encryption Facility for OpenPGP commands like -g that generate key pairs to serve as the system key for signatures.
Environment variables for the Java JVM: IBM provides sample code in SAMPLIB for the Java environment script to configure any environment variables for the Java JVM. For sample code, see Sample JCL and code.
