Questions still occasionally arise regarding the need to run the SERSET job and the purpose of the SERXPTIK module. To summarise:

- SERXPTIK is a small, executable module that is loaded into CSA on every LPAR hosting ZMF users or batch jobs.

- This module is executed each time a user connects to a ZMF Server started task using the TCP/IP connection method – either explicitly or when technically required (e.g. when connecting across LPARs using Load Balancing Option (LBO) functionality).

- It is used in the generation of a Security Server PassTicket for the connecting user or batch job.

- This PassTicket is validated by the ZMF Server started task at connection time.

- SERXPTIK is automatically loaded into CSA whenever a ZMF Server task is started on an LPAR.

- For LPARs not hosting a ZMF Server task, you must run the SERSET job to load SERXPTIK into CSA before any users or batch jobs attempt to connect to any ZMF Server started task from that LPAR.

- IPLing the LPAR will result in SERXPTIK being removed from CSA.

- Hence SERXPTIK needs to be reloaded into CSA after every IPL.

Further information on SERSET and SERXPTIK can be found in the section named 'Step 6: Add PassTicket Support In Sernet' within the ZMF Installation Guide. The 8.2 Patch 6 version of this manual is currently available here.
