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.
