Rebuilding Installation JCL

The JCL install jobs that move a change package into production must be built using z/OS file tailoring prior to install time. Your ZMF administrator configures the repository to perform this file tailoring automatically — either when the package is frozen or when the final package approval action is received. However, changes to a package may be required after the initial file tailoring is performed, and these changes may require a rebuild of the installation JCL. This may be done on demand using the Rebuild Install JCL function.

The following rules apply to the Rebuild Install JCL function:

  • The package must be in frozen (FRZ) status.
  • The scheduled install date must be in the future.
  • An initial file tailoring of the installation JCL must already have been performed for the change package. Look for file tailoring program CMN_ADSP in the job log (where the underscore represents a ZMF started task identifier) if the prior execution of file tailoring is in doubt.

Refer to the ChangeMan ZMF User’s Guide for more information about file tailoring and rebuilding the JCL install jobs.

Invoking the Job and Viewing Results

The Rebuild Install JCL function is invoked from the following menu in the Serena perspective.

  • In the Serena Explorer view, expand the ZMF Applications node, the node of the relevant application, and the Packages node below it. Right-click on the name of the package for which installation JCL should be rebuilt. When the contextual menu displays, select the Rebuild Install JCL option. See Working with ZMF Packages for more information.

The success or failure of the Rebuild Install JCL request is reported in a dialog window.
