How do I remove an IMS system from an existing group Log or History File?
Assume that GRP1 contains IMS systems IMSA, IMSB, and IMSC. You determine that IMSC will no longer be participating in GRP1. IMSC will become a standalone IMS system in another sysplex. You want to remove all details for IMS from the DELTA PLUS Log and History File.
DELTA PLUS provides a batch utility that allows users to remove an IMS system from an existing Group Log and History file. For complete details, see DLPCNTL member DLP#XUT3. Ensure that you review and edit this JCL before execution.
Note
Before executing this utility, ensure that you have a current backup of the Log and History File data sets.
