Bottleneck Analysis workspace

The Bottleneck Analysis workspace displays information for all eligible CICS® transactions.

This predefined workspace contains the following views:

  • CICS Wait Reason Distribution bar chart that shows wait reason descriptions along the Y axis when a display threshold of 10 percent is reached.
  • Bottleneck Analysis table view that identifies the various wait reasons over a 10% threshold encountered by CICS tasks over a fixed time interval

The workspace displays are provided by the CICSplex Bottleneck Analysis attribute group.

By default, the Bottleneck Analysis table view displays information for all eligible CICS transactions. You can limit the display to a single group by adding a " GROUPNUM EQ " predicate to the bottleneck query. The Tivoli® Enterprise Portal Properties page lets you add the Group Number attribute, provided only one group is specified in the predicate.

It is not possible to ask for several groups at one time, while omitting others. For instance, if ten groups have been defined to OMEGAMON®, a query cannot ask for groups 3, 5, and 9. Thus, if the Bottleneck Analysis query asks for more than one group (using multiple predicates or use of something other than an EQ logical operator), an error message is written to the RKLVLOG and the query is ignored. A display of all transactions is obtained by omitting the Group Number predicate from the Bottleneck Analysis query.

In the CICS Wait Reason Distribution bar chart, to replace the wait reason description with a shorthand version of the resource type and name, add the Resource Type/Name attribute to your query using the Tivoli Enterprise Portal Properties page.

This tactic, for example, replaces "FC:Wait for user" with "FCCFQS /(none)" for those accustomed to the OMEGAMON for CICS (3270 Classic) interface. The display threshold is controlled using the Display Threshold attribute supplied in the default query and can be changed to any value you want. Omitting the attribute, or setting its value to zero, results in the display of all defined wait reasons. Users of the OMEGAMON for CICS (3270 Classic) interface and Tivoli Enterprise Portal monitors can set any value they choose.
