CICS IA CIU2293W CINC Collector is already active for userid shared CIUCNTL file

The code in CIUACM60 in the INIT proc does an EC ASSIGN for the USERID, APPLID and SYSID. The MAIN proc reads the CINCUSER record from the CIUCNTL control file and if it finds the record (which it will if the CIUCNTL is shared by multiple CICS regions) and the AUCR_CMDF_FLAGS byte in the AUCR_CMDF_ACTIVE field is set on, the CIU2293W message is issued. There is no checking to see if this is for this same CICS region. The CINCUSER record key (AUCR_KEY) only consists of the AUCR_CMDF_USERID for the key. There is no applid or sysid qualifier to only read the user record for the current region.

After review with the CICS IA development team, the documentation for the CIU2293W message will be amended to state:

Explanation
The Command Flow collector is already active for a user when an attempt to start the Command Flow collector for the same user is made. If the CIUCNTL control file is shared across the CICS regions then only one Command Flow collector can be active for a given user at any given time in any of the shared regions.

System action
The second collector start request is terminated because only one active collector at a time is permitted for each user.

User response
Press F7 (Statistics) on the CICS IA Command Flow Options panel to find out on which regions the Command Flow collector is already running for the user.
