Question:
How can I find out which TPX user exits are active?
Is there a simple way to check if the TPX region has customer written user exits loaded and active?
Answer:
TPX 5.4 published solutions RO88385 & RO88384 introduced the ability to display the status of user exits as well as quiesce (deactivate) a user exit via TPX Operator (TPXOPER) commands:
- D EXIT
- Q EXIT=userexit
Complete details have been added to the TPX 5.4 documentation wiki:
You can also verify the version of a load module by checking the time stamp in the TPX LOG.
All the load module names of TPX exits start with TPXU.
Check the TPX LOG for the TPXL0003 load messages at the beginning of the log for following names:
TPXUGACB - ACB Selection Exit TPXUPSYM - ACL Parameter Exit TPXUCMND - Command Exit TPXUCSIM - Command Simulation Exit TPXUENDE - Encrypt/Decrypt Exit TPXUERR1 - Error Processing Exit TPXULOGW - LOG Writer Exit TPXULOGN - Logon Exit TPXUMAIL - Mail Exit TPXUMENU - Menu Exit TPXUPBNR - Print Banner Exit TPXUPSEL - Printer Selection Exit TPXUQRSP - Query Response Exit TPXUQUEU - Queue Exit TPXURECV - Receive Exit TPXUROUT - Route Exit TPXUSEND - Send Exit TPXUSIST - Session Initiation/Termination Exit TPXUSNSF - Signon and Signoff Exit TPXUSWIN - Switch-in Exit TPXUTOOO - Timeout Option Override Exit TPXUVIEW - View Security Access User Exit
The TPXL0003 message will usually include the assembly time stamp. This can be compared to the known values for the delivered version of the module for your release.
Example 1:
Our distributed TPX load library contains a TPXUSNSF exit module:
TPXL0003 TPXUSNSF-07/25/13-11.25 in TPX 5.4
TPXL0003 TPXUSNSF-09/22/09-10.19 in TPX 5.3
TPXL0003 TPXUSNSF-12/27/06-12.39 in TPX 5.2
- If you see above TPXL0003 message with this date/time stamp then you are running our distributed TPXUSNSF exit which basically implements profile assignment for dynamic users.
- If you see a TPXL0003 message for the TPXUSNSF exit with a different date/time stamp then you are running your own written exit.
Example 2:
Similarly, the distributed TPX load library also contains a TPXUENDE exit module. The TPXL0003 message shows as:
TPXL0003 TPXUENDE- blanks rather than a date/time stamp
This module implements a CA proprietary encrypt/decrypt algorithm for storing passwords in memory so that they can be used in ACL/E programs and in session data.
Via this exit you can implement other encrypt/decrypt algorithms.
