Considerations for STALL condition

Stabilized feature: CICSPlex® SM Real-Time Analysis (RTA) is stabilized. Consider moving to Policy system rules or to a dedicated monitoring product such as IBM OMEGAMON for z/OS. See also Stabilization notices and discontinued functions.

A STALL condition occurs when one or more resources have impacted the processing of a CICS® application. Resource contention impacts task processing. Parameters you specify in the startup JCL determine when a CICSPlex SM STALL message is issued.

You can set the parameters conservatively so that you receive notification while the system is still functioning, even though resource contention is having a serious impact.

Resolution of a STALL condition might prevent a more serious situation (such as an SOS or MAXTASK) from occurring. For example, a lack of temporary storage could prevent a task from completing and trigger a STALL condition.

For more information about the STALL parameters and a list of possible stall conditions, see CICSPlex SM system parameters in EYUPARM data set.
