Mirror transaction does not time out

A task has suspended in CICS® awaiting a response from an ECI client application during an extended LUW.

Symptom

Mirror tasks are left running in CICS.

Probable cause

The default ECI mirror transaction (CPMI or CSMI) uses a PROFILE of DFHCICSA. The profile has an RTIMOUT value of NO. This means that if a request using an extended LUW is suspended in the client application whilst not in an ECI call, the CICS mirror transaction fails to time out.

Action

To enable the mirror transaction set RTIMOUT, in the mirror transaction's profile, to purge extended LUW tasks hanging in the client application. This should ensure that if no response is received from the client application after the timeout period has elapsed CICS purges the mirror transaction and rolls back the associated unit of work. It is the RTIMOUT value that causes CICS to purge the mirror.

See Timeout of the ECI request for more information.
