CICSplex Intercommunication Summary attribute group

The CICSplex Intercommunication Summary attribute group provides information about the connection status of the CICS regions.

Note: The attributes within the CICSplex Intercommunication Summary group are stored for historical retrieval within the Tivoli Data Warehouse. Selected attributes within this group are candidates for the Tivoli Data Warehouse 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.

CICS SYSIDNT Indicates four character CICS system ID assigned to the CICS region. The value format is an alphanumeric string, maximum four characters, that is case-sensitive. CICS system IDs are always in uppercase characters.

Connection Count Indicates the number of connections among this region and others. This value includes MRO and ISC connections. The value format is an integer of maximum four bytes.

CPU Utilization Indicates the percentage of CPU time consumed by the CICS address space. The value is a percentage in the range of 0-999. When specifying a fractional value, include a decimal point and either zero or one decimal place; for example, 5.2.

The accumulated CPU time for the CICS address space is noted at the beginning and end of a short elapsed-time interval. The difference between these two values is the amount of CPU consumed in the CICS address space during that interval; this difference is then represented as a percentage of the elapsed-time interval. Example: If the:

Accumulated CPU time at the start of the time interval equals 2 seconds.
Length of the interval equals 10 seconds.
Accumulated CPU time at the end of the time interval equals 5 seconds
CPU consumed during the 10-second time interval equals 5-2 seconds, which equals 3.

Then percent of CPU used during the time interval equals 3/10, or 30%.

A low-to-zero value indicates the absence of a workload or non dispatch by the z/OS system. A high-to-100% (or greater) value indicates a heavy workload or a potential loop in either the application or CICS code. If the workload is running on multiple CPUs, the CPU utilization can exceed 100%.

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

When a situation is true, the system 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, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.

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

Transaction Rate Indicates the average number of transactions executed in one minute of elapsed time. The value format is an integer of maximum four bytes.

Example: If the statistics are collected every 10 minutes and the number of transactions during the last 10 minutes is 300, the average number of transactions per minute is 30.

VTAM Applid Indicates the eight character, VTAM applid of the CICS region. Each CICS region has a unique VTAM applid. The value format is an alphanumeric string, maximum eight characters, that is case-sensitive. The VTAM applid is always in uppercase characters.

VTAM Generic Applid Indicates the generic VTAM applid of the CICS region. Each CICS region has a unique VTAM applid. The value format is an alphanumeric string, maximum eight characters, that is case-sensitive. The generic VTAM applid is always in uppercase characters.

Worst Case ISC System Indicates the name of the connection with the highest percentage of ISC links in use. The value format is an alphanumeric string of maximum four characters.

Worst Case MRO System ID Indicates the name of the connection with the highest percentage of MRO links in use. The value format is an alphanumeric string of maximum four characters.

Worst ISC Connection Number of AIDs Indicates the number of AIDs for the worst case ISC system. The value format is an integer of maximum two bytes.

Worst ISC Connection Number of Links Defined Indicates the number of links defined for the worst case ISC system. The value format is an integer of maximum four bytes.

Worst ISC Connection Percent of Links in Use Indicates the percentage of ISC links in use for the worst case ISC system. The value format is a percentage in the range of 0-100.

Worst MRO Connection Number of AIDs Indicates the number of AIDs for the worst case MRO system ID. The value format is an integer of maximum four bytes.

Worst MRO Connection Number of Links Defined Indicates the number of links defined for the worst case MRO system ID. The value format is an integer of maximum two bytes.

Worst MRO Connection Percent of Links in Use Indicates the percentage of links in use for the worst case MRO system ID. The value format is a percentage in the range of 0-100.
