The predefined situations in this category monitor the Task Class Analysis attributes.
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 re-evaluate 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 XE for CICS on z/OS 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.

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 report 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 XE for CICS on z/OS 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.
