DFHXM0501 applid CICS cannot satisfy request for MXT. Value mxtvalue has been used instead.

Explanation

The value entered for MXT cannot be handled by the system. mxtvalue is the largest value for which CICS has been able to acquire task storage.

The majority of the task storage required is now acquired from CICS DSAs.

System action

The system continues to run with a MXT value of mxtvalue.

User response

Check that the original value entered for MXT was correctly typed. If the value is mistyped, use CEMT to amend the MXT value (you are unlikely to be able to force the value higher). Remember that MXT now only includes user tasks and so it should not need to be set to a value as high as in previous releases.

If the value mxtvalue is acceptable, no action is necessary.

If the value mxtvalue is too small, check to see which programs, apart from CICS, are running in this region. To relieve the storage constraint, either increase the DSALIM or EDSALIM of the system to give CICS more storage for its own use. For further details about storage allocation at initialization, see the Installing CICS TS.
