CICSplex Bottleneck Analysis attribute group

The CICSplex Bottleneck Analysis attributes report on the various wait reasons encountered by CICS tasks over a fixed time interval. Use the CICSplex Bottleneck Analysis attributes in situations to determine where bottlenecks are occurring.

These attributes provide data for the Bottleneck Analysis table view.

Note:
The attributes within the CICSplex Bottleneck 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 8 characters, and case-sensitive. CICS region names are always in uppercase characters.

Detailed Long Term Percentage Is the percent of time transactions spent waiting on specific resources during the long-term collection interval. The value format is 0 - 100.

Detailed Short Term Percentage Is the percent of time transactions spent waiting on specific resources during the short-term collection interval. The value format is 0 - 100.

Dispatcher Call Is the specific type of wait performed by the dispatcher on behalf of a wait request. The valid format is an alphanumeric string with a maximum of 9 characters.

Display Threshold Is the filter used to screen out resources that have a low wait percentage. The valid format is an integer, in the range 0-100.

Group Number Is the numeric identifier of the selected OMEGAMON group. If all groups are requested, this value is zero. The valid format is an integer, with a maximum of two digits, in the range 1-30.

Issuing Module Is the name of the CICS module that issues the wait, or MULTIPLE, if more than one CICS module can issue the wait. The valid format is an alphanumeric string with a maximum of 8 characters.

Long Term Elapsed Time Is the amount of time that has passed during the long-term collection interval. The valid format is either seconds, or hh:mm:ss.

Long Term Interval Is the time span over which long-term bottleneck samples are collected. The valid format is either seconds, or hh:mm:ss.

Long Term Sample Count Is the number of transactions that have participated in the long-term collection interval sample. The valid format is an integer.

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, 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.

Resource Name Is the name of the resource on which transactions are waiting. The valid format is an alphanumeric string with a maximum of 8 characters.

Resource Subtype Is the CICS designation for the variable resource type on which transactions are waiting. The valid format is an alphanumeric string with a maximum of 8 characters.

Resource Type Is the CICS designation for the type of resource on which transactions are waiting. The valid format is an alphanumeric string with a maximum of 8 characters.

Resource Type/Name Is the concatenation of the resource type and resource name values. The valid format is an alphanumeric string with a maximum of 17 characters.

Short Term Elapsed Time Is the amount of time that has passed during the short-term collection interval. The valid format is either seconds, or hh:mm:ss.

Short Term Interval Is the time span over which short-term bottleneck samples are collected. The valid format is either seconds, or hh:mm:ss.

Short Term Sample Count Is the number of transactions that have participated in the short-term collection interval sample. The valid format is an integer.

Summary Short Term Percentage Is the percent of time transactions spent waiting on generic resources during the short-term collection interval. The valid format is 0 - 100.

Summary Long Term Percentage Is the percent of time transactions spent waiting on generic resources during the long-term collection interval. The valid format is 0 - 100.

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

Task Type Is the category of tasks that can apply to this type of wait. Valid values are User, System, and Both.

Translated Wait Reason Is a brief outline of the value found in the resource type. The valid format is an alphanumeric string.

Wait Reason Description Is a brief outline of the value found in the resource type. The valid format is an alphanumeric string with a maximum of 20 characters.

Wait Type Is the descriptive rendition of the CICS resource type. The valid format is an alphanumeric string with a maximum of 8 characters.
