Wait Analysis report

The Wait Analysis report provides a breakdown of wait activity by Transaction ID (or other ordering fields). You can see at a glance which CICS® resources are causing your transactions to be suspended. This report can help you to quickly identify the possible source of a performance response time problem.

To request the report, enter line action S against the Wait Analysis Performance Report on the Report Set panel. If reports of this type have been previously specified, the list of Wait Analysis Reports is displayed. Otherwise, the Wait Analysis Report panel is displayed for you to define your first report of this type.

This panel displays the list of Wait Analysis Reports in this Report Set. You can select (edit), delete, or include/exclude any report, insert new ones, or rearrange them (move/copy).

The options and line actions are the same as those for the Performance List Reports panel, except there is no Report Form. See Performance List report.

To display the Wait Analysis Report panel, enter line action S against the Wait Analysis Performance Report on the Report Set panel, then if the list of previously specified reports is displayed, enter line action S against a particular report in the list.

Use this panel to specify report options and record selection criteria for the Wait Analysis report. The report format is fixed. The only mandatory option is the DDname for the report output. You can let the other options default.

The report options are the same as those for the Performance List Report (see Performance List report), except there is no Report Form and there are additional ordering and processing options:
Order by
Specify the Field names that the Wait Analysis report is to be ordered by. If not specified, the report is ordered by Transaction ID. You can use Prompt (F4) to select from a list of allowed fields: TRAN, START, STOP, APPLID, PROGRAM, TERM, USERID, APPLPROG, APPLTRAN, FCTY, LUNAME, RLUNAME, RPTCLASS, SRVCLASS, TCLASSNM, TCPSRVCE, TERMCNNM, ISIPICNM, WBATMSNM, WBPIPLNM, WBPROGNM, WBSVCENM, WBSVOPNM, WBURIMNM.
Time Interval
The time interval applies when you want to summarize wait activity over time, and is only applicable when one of the Ordering fields is a time stamp (START or STOP). For example, specify 00:15:00 if you want to summarize activity over 15 minute intervals.

Specify a value in the range 00:00:01 (1 second) to 24:00:00 (24 hours). The default is 00:01:00 (1 minute).

A time interval of less than one hour must fit evenly into the hour. CICS PA will round it down to the nearest interval that aligns to the hour. For example, 1.35 is reduced to 00:01:30 minutes which will produce 40 interval report lines for each hour of data.

A time interval of more than one hour must fit evenly into the day. CICS PA will round it down to the nearest interval that aligns to the day. For example, 10.30.23 is reduced to 08:00:00 hours which will produce 3 interval report lines for each day of data.

Minutes take precedence for an abbreviated entry. For example:
1
becomes 00:01:00
1.1
becomes 00:01:00 (rounded down from 00:01:01)
1.1.1
becomes 01:00:00 (rounded down from 01:01:01)

This option generates the INTERVAL(hh:mm:ss) operand.

CICS PA provides a default Report Output DDname in the format WAITnnnn where nnnn is 0001-9999.
