Issue/Introduction

How to avoid the messages TPXL5130 and TPXL5131 being written into the TPXLOG?

Environment

TPX® Session Management for z/OS

Resolution

When using TPX as a Generic Resource then you will find messages TPXL5130 and TPXL5131 logging on in the TPX Log for every User:

TPXL5131 <day> <time> CA-TPX CMPL EXIT DRIVEN, RC=00000000, RSN=00000000 
TPXL5130 <day> <time> CF-REQ: Func=0000, Rc=00000008, Rsn=0C1C0825, Lst#=0000, Enty=xxxx 
TPXL5131 <day> <time> CA-TPX CMPL EXIT DRIVEN, RC=00000008, RSN=0C1C0825 
TPXL5130 <day> <time> CF-REQ: Func=0000, Rc=00000008, Rsn=0C1C0825, Lst#=0000, Enty=xxxx

 These messages protocol a request to the Coupling Facility. They are informational if the logon request is successful and are helpful in case a problem occurs.

The Return and Reason Codes are documented in the IBM manual "Abstract for MVS Programming: Sysplex Services Reference Return and Reason Codes". 

1.  Use the Log Writer User Exit if those messages are not required to be written to the TPX Log.
2. This exit receives control any time TPX is about to write a message to the TPX Log.
3. The default Exit provided in dataset 'hlq.CB0VSRC(TPXULOGW)' does check for these two messages and discards them instead of writing them into the log.
4. It is required to link this exit without any change with the name TPXULOGW in order to remove messages TPXL5130 and TPXL5131 from the TPX Log.
