Question:

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

Answer:

When you are 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 "z/OS MVS Programming: Sysplex Services Reference" and the z/OS 2.2 Version can be found here: http://www-01.ibm.com/support/knowledgecenter/#!/SSLTBW_2.2.0/com.ibm.zos.v2r2.ieai700/toc.htm

(NOTE: As it is an IBM manual CA technologies does not take any responsibility for the information provided in it)

 

If you do not want those messages written to the TPX Log you can use the Log Writer User Exit.

This exit receives control any time TPX is about to write a message to the TPX Log.

The default Exit we provide in dataset 'hlq.CB0VSRC(TPXULOGW)' does check for these two messages and discards them instead of writing them into the log.

So you only need to link this exit without any change with the name TPXULOGW in order to remove messages TPXL5130 and TPXL5131 from the TPX Log.
