There are three ways to find out which release and service pack of TPX you are running:
1. TPXOPER session
If you have access to TPXOPER, then logon to that session. In the upper-right corner you will see a string:
'*********** 5.4/00 TEN0200'
The string '5.4/00' represent Release and Service Pack of the TPX region (TEN0200 is the name of this panel.)
2. TPX Joblog
The TPX Joblog contains the message:
TPX0007 TPX STARTING UP AS TPX54PRD , VERSION 5.4 LEVEL 00
This indicates the used release and service pack.
3. Logon screen
When using the standard TPX logon panel, in the upper right of the Logon screen, located right of the large letters 'TPX' this string: "REL 5.4/00". This tells you the release and service pack of the TPX region.
Note: Your installation might use a customized TPX logon panel not containing the release information.
