 ******************************* Bottom of data ********************************

The System Control panel shows you the default processing results of job APCYJLNA. APCYJLNA adds a new entry in this list for every new job name of a CICS region that is processed. By default, each new entry is added with a new distinct internal ID and the job name is used as the system name.

When creating system names, consider using appropriate definitions for the later easy use of wildcards for selecting systems that should be included for reporting or other tasks.

The following functions can be performed using the System Control panel:

• The default system name can be changed to a user-defined system name. The system name (whether user defined or default) should be used on other panels to filter the measurement data being accessed.
• New entries can be inserted to allow Performance Management Assistant to aggregate CICS measurements. All entries must have the same user-defined internal ID and the same user defined system name. The job names must be the real job names of the CICS startup jobs.

With the CICS feature, information about measurements can be aggregated to information for a whole online system. To understand this concept, assume the following parameters:

Using the illustration above as an example, all measurements of CICS regions AOR1CICS, AOR2CICS, and AOR3CICS are interpreted and calculated by Performance Management Assistant to one logical system MRO. In the online dialog, the data of the measurements is seen as one although a transaction is called in all three regions. Thus, Performance Management Assistant aggregates the data of three measurements. For controlling transaction performance, look in the online dialog for the specific transaction in system MRO as one line of information.

• To have multiple measurements a day for one CICS, you can define an entry for each measurement and determine the time range of the start of the measurement. Use different values than from 00 to 24 only if you plan to measure a CICS region more than once a day. If you measure one CICS in the morning and again in the afternoon, job APCYJLNA know which measurements belong to which system by interpreting start time information. For example:

Change the parameter or the schedule plan for job APCCJINV accordingly.
