Temporarily uninstalling Z Abend Investigator

If for any reason you want to temporarily uninstall Z Abend Investigator, then the easiest way is to do the following:

  1. Rename the following invocation exit load modules in data set HFZ.SHFZAUTH, for example, by changing the first character 'I' to an 'O':
    • HFZXCCEE
    • HFZXCEE
    • HFZXCX53
    • HFZXDCAP
    • HFZXTSEL
  2. Issue this MVS™ operator command:
    F LLA,REFRESH
  3. If using z/OS® 2.2 or later, issue this MVS operator command:
    SETPROG EXIT,MODIFY,EXITNAME=IEAVTABX_EXIT,MODNAME=HFZXDCAP,STATE=INACTIVE
  4. If using CICS®, then either bounce all CICS systems, or use the Z Abend Investigator-provided CFA transaction to uninstall all installed CICS invocation exits.

Having done the above, then the exit processes are not able to find the expected load modules, and processing continues without them.

Note: Remember to rename the load modules back to their original names before applying any maintenance.

Reinstallation: To reinstall Z Abend Investigator, do the following:

  1. Rename the load modules in step 1 of the above procedure back to their original names.
  2. Issue this MVS operator command:
    F LLA,REFRESH
  3. If using z/OS 2.2 or later, issue this MVS operator command:
    SETPROG EXIT,MODIFY,EXITNAME=IEAVTABX_EXIT,MODNAME=HFZXDCAP,STATE=ACTIVE
  4. If using CICS, then either bounce all CICS systems, or use the Z Abend Investigator-provided CFA transaction to install all required CICS invocation exits.
