Task Class Analysis situations

The predefined situations in this category monitor the Task Class Analysis attributes.

Note: All the attribute names in this group are prefixed with CICSplex_Task_Class_Analysis except where stated.

CICSplex_ClassMax_Warning

Warning threshold exceeded for class MAXTASK.

Generally, your application must add transactions to a transaction class to restrict access to resources in CICS®. If response time is not acceptable, it can be necessary to reevaluate why the task has been placed in a transaction class. If you determine that the class MAXTASK value is too low, you can change it with either OMEGAMON AI for CICS or the CICS CEMT transaction.

Formula: If the value of Percent_of_Limit is greater than 80 and the value of Percent_of_Limit is less than or equal to 90 then situation CICSplex_ClassMax_Warning is true.

CICSplex_ClassMax_Critical

Critical threshold exceeded for class MAXTASK.

Generally, your application must add transactions to a transaction class to restrict access to resources in CICS. If response time is not acceptable, it can be necessary to reevaluate why the task has been placed in a transaction class. If you determine that the class MAXTASK value is too low, you can change it with either OMEGAMON AI for CICS or the CICS CEMT transaction.

Formula: If the value of Percent_of_Limit is greater than 90 then situation CICSplex_ClassMax_Critical is true.

CICSplex_AtClassMax_Warning

Warning threshold exceeded for class MAXTASK limit.

When the limit is reached for a class, a new task belonging to the same class cannot be run until an old task has terminated. Use the Transaction Analysis workspace to determine whether a problem is preventing tasks within the specified class from completing in a timely manner. For example, tasks can be waiting for an enqueue, or CICS itself can be short-on-storage. If you find that the class MAXTASK value is too low, you might change it with either OMEGAMON AI for CICS or the CICS CEMT transaction.

Formula: If the value of Percent_of_Limit is greater than or equal to 100 then situation CICSplex_AtClassMax_Warning is true.

CICSplex_AtClassMax_Critical

Critical threshold exceeded for class MAXTASK limit.

When the limit is reached for a class, a new task belonging to the same class cannot be run until an old task has terminated. Use the Transaction Analysis table view to determine whether a problem is preventing tasks within the specified class from completing in a timely manner. For example, tasks can be waiting for an enqueue, or CICS itself can be short on storage. If you find that the class max task value is too low, you might change it with either OMEGAMON AI for CICS or the CICS CEMT transaction.

Formula: If the value of Percent_of_Limit is greater than or equal to 100 then situation CICSplex_AtClassMax_Critical is true.
