Recovery Manager Analysis situations

The situations in this category warn you of possible unit-of-work problems, as raised by the CICS Recovery Manager.

CICSplex_RecMgr_Warning
Current Shunted UOW Count greater than 10.

The CICS Recovery Manager is reporting that there are currently more than 10 units of work shunted for Indoubt. This indicates that the CICS region performance will start degrading unless remedial action is taken relating to the reason for the shunted units of work. Use the unit-of-work queries available within OMEGAMON XE for CICS on z/OS to verify whether the cause of failing transactions is related and the related Take Action commands to restore system and application integrity.

Formula

If the value of CICSplex_Recovery_Manager_Details.Current_Indoubt_shunted_UOWs
 is greater than 10
then situation CICSplex_RecMgr_Warning is true.
CICSplex_UOW_DSNFail_Warning
Data set associated with this UOW has been shunted.

The unit of work associated with this alert has been shunted because of a syncpoint failure associated with the specified data set. Note that failures during syncpoint processing may result in locks being retained by the UOW. This may result in system degradation if action is not taken to release the locked resources.

Formula

If the value of CICSplex_Unit-of-work_DSN_Failure_Details.Dataset_name equals blank
then situation CICSplex_UOW_DSNFail_Warning is true.
CICSplex_UOW_Link_Warning
Resynchronization status is UNAVAILABLE or UNCONNECTED.

A distributed unit of work cannot resynchronize itself because the connection to its link partner is either unconnected or unavailable. To allow resynchronization to complete successfully, you must set the connection to the remote system to Acquired.

Formula

If the value of CICSplex_Unit-of-work_Link_Details.Resync_status equals Unavailable
or the value of CICSplex_Unit-of-work_Link_Details.Resync_status equals Unconnected
then situation CICSplex_UOW_Link_Warning is true.
