z/OS commands

Java™ and Groovy both provide easy mechanisms to create directories, copy files, and even invoke external programs. However, these mechanisms are only for use with distributed operating systems such as Unix, Linux®, and Windows™ that use hierarchical file systems (HFS). There is usually no native support for working with z/OS data sets or invoking z/OS programs and commands. DBB provides the following set of Java classes to be used for issuing z/OS commands:

• CreatePDS
• CopyToPDS
• CopyToHFS
• MVSExec
• ISPFExec and TSOExec
• JobExec (since 2.0.1)
• JCLExec (deprecated)
• UnixExec (since 2.0.2)

This section of documentation is meant to provide an overview of these commands as well as tips on how to use them in your build scripts. For a more detailed look at the Java API specifics for each command, see the Toolkit Javadoc. All of the z/OS command Java classes are located in the com.ibm.dbb.build package.
