I had configured WLM so the MQ started tasks (CSQ*) were defined as a low priority STC.

But I could see from SDSF, that the CSQ9CHIN’s SrvClass was STCHIM, and CSQ9WEB’s was STCHIM. It took me a couple of hours digging to find out why.
Higher up the list, the WLM definitions had

There is a definition for ONLPRD (online production), a group of transaction names (Transaction Name Group).
From option 5 Classification Groups, of the main WLM panel it displays
Classification Group Menu
Select one of the following options.
__ 1. Accounting Information Groups 14. Plan Name Groups
2. Client Accounting Info Groups 15. Procedure Name Groups
3. Client IP Address Groups 16. Process Name Groups
4. Client Transaction Name Groups 17. Scheduling Environment Groups
5. Client Userid Groups 18. Subsystem Collection Groups
6. Client Workstation Name Groups 19. Subsystem Instance Groups
7. Collection Name Groups 20. Subsystem Parameter Groups
8. Connection Type Groups 21. Sysplex Name Groups
9. Correlation Information Groups 22. System Name Groups
10. LU Name Groups 23. Transaction Class Groups
11. Net ID Groups 24. Transaction Name Groups
12. Package Name Groups 25. Userid Groups
13. Perform Groups 26. Container Qualifier Groups
Most of these had no definition, but option 24. Transaction Name Groups gave me

and these names match what is in the classification rules section above.
Option 3 to modify ONLPRD, gave
Modify a Group Row 1 to 8 of 8
Command ===> ____________________________________________________________
Enter or change the following information:
Qualifier type . . . . . . . : Transaction Name
Group name . . . . . . . . . : ONLPRD
Description . . . . . . . . . Online Production Subsystems
Fold qualifier names? . . . . Y (Y or N)
Qualifier Name Start Description
%%%%DBM1 ___ DB2 Subsystems
%%%%MSTR ___ DB2 Subsystems
%%%%DIST ___ DB2 Subsystems
%%%%SPAS ___ DB2 Subsystems
CICS* ___ CICS Online Systems
IMS* ___ IMS Online Systems
CSQ* ___ MQ Series
and we can see that MQ started tasks starting with CSQ are in this group.
As this definition is higher in the classification rules list – it will take precedence over any definitions I had defined lower down.
Because there was a definition (within the Started classification)
____ 1 TNG ONLPRD ___ STCHIM ________
Started tasks in the group ONLPRD are classified as STCHIM, and so this explains why the classification of the MQ address spaces were “wrong”.
I had several options
- Change the groups and put MQ in its own group with STCLOM
- Move my CSQ9* specific definitions above the group.
