Installing enqueue model definitions

CICS® uses ENQMODEL resources with z/OS® global resource serialization to provide sysplex-wide protection of resources that are used by multiple applications. As ENQMODELs usually have the default status of ENABLED, the order of installing ENQMODELs must follow the rules for ENABLING ENQMODELs.

About this task

When you enable ENQMODELs that form nested generic ENQnames, you must do so starting with the most specific, and continue to the least specific.

For example, if you have ENQMODELS that have ENQnames of ABCD*, ABC*, and AB*, enable them in this order:
  1. ABCD* (the most specific)
  2. ABC*
  3. AB* (the least specific)
