This section describes the CICS® global user exits (GLUE) and user replaceable modules that are used by CICSPlex® SM.
The way these exits are used by CICSPlex SM conforms to the standard described in the CICS Customization Guide. CICSPlex SM uses these exits only to acquire information; the application environment is not altered.
CICSPlex SM uses the dynamic routing program user replaceable module (DTRPROG) as part of workload balancing.
The XMNOUT and XSTOUT exits are used when monitoring services are enabled for a managed application system (MAS).
These exits are used to obtain monitoring and statistics information and always return a "continue processing" return code. They are disabled when a shutdown request for the MAS is received.
The XMEOUT, XDUREQ, XDUREQC, XRSINDI and XDUOUT exits are used when topology requests are enabled for a local MAS. The XMEOUT exit is used to detect short on storage sick and well health events.
