CICSplex Task Class Analysis attribute group

The CICSplex Task Class Analysis attributes provide details about the transaction classes defined to CICS. They enable you to see how close your CICS systems are to the limits set for the number of tasks in a given class. Use the Task Class Analysis attributes in situations to monitor activity for a specific transaction class. If the percentage for a class consistently runs at 100%, it can indicate that tasks defined in a class are not initiated because the maximum number of tasks in a class has been reached. If CICS is under using processor resources, it can be worth considering an increase in the class limits to allow more work to flow through the system.

These attributes provide data for the Task Class Analysis table view.

Note:
The attributes within the CICSplex Task Class Analysis group are stored for historical retrieval within the Tivoli Data Warehouse. Selected attributes within this group are candidates for the TDW's summarization and pruning features.

CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters, and case-sensitive. CICS region names are always in uppercase characters.

Class Limit Indicates the maximum number of tasks allowed to run in the transaction class. The value format is a positive integer, maximum four bytes.

Class Name Indicates the transaction class name. The value format is an alphanumeric string, maximum eight characters.

Current Tasks Indicates the current task count in the transaction class. The value format is a positive integer, maximum four bytes.

Number Queued Indicates the number of transactions that are queued. The value format is a positive integer, maximum four bytes.

Origin Node Is the combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.

When a situation is true, Tivoli Enterprise Portal compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, Tivoli Enterprise Portal changes the status of the item accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.

Peak Tasks Indicates the highest number of active and queued transactions. The value format is a positive integer, maximum four bytes.

Percent of Limit Indicates the number of active tasks in a class divided by the class limit. The value format is a percentage in the range 0-100.

Percent of Queue Limit Indicates the number of queued tasks in a class divided by the queue limit. The value format is a percentage in the range 0-100.

Queue Limit Indicates the maximum number of tasks that can be queued. The value format is a positive integer, maximum 4 bytes.

System ID Indicates the 4-character name that uniquely identifies an active z/OS operating system. The value format is an alphanumeric string, maximum 4 characters, and case-sensitive. z/OS System IDs are always in uppercase characters.

Times at Limit Indicates the number of times the transaction class limit has been reached. The value format is a positive integer, maximum 4 bytes.
