Enabling Dialog Statistics

Dialog statistics can be collected only if task and transaction statistics collection is enabled. Task statistics are enabled at system generation time. Transaction statistics can be enabled at either system generation or runtime in the following manner:

• To enable transaction statistics at system generation time, use the STATISTICS parameter in the SYSTEM statement, specifying TASK, WRITE, and TRANSACTION.
• To enable transaction statistics at runtime, use the DCMT VARY STATISTICS TRANSACTION command.

The DCMT VARY ADSO STATISTICS command is used to enable or disable dialog statistics and to specify whether individual statistics are collected for selected dialogs or for all dialogs, as follows:

• DCMT VARY ADSO STATISTICS ON ALL DIALOGS enables dialog statistics and specifies that sets of statistics are to be collected for overhead activity and for each dialog that is executed during an CA ADS application.
• DCMT VARY ADSO STATISTICS ON SELECTED DIALOGS enables dialog statistics and specifies that sets of statistics are to be collected for overhead activity and for each selected dialog that is executed during an CA ADS application. One additional set of statistics is collected to accumulate statistics for all nonselected dialogs.
• DCMT VARY ADSO STATISTICS OFF disables the dialog statistics feature.

If no DCMT VARY ADSO STATISTICS command is issued prior to the execution of an application, the runtime system uses the default specification established at system generation.
