 ******************************* 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 an IMS 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 by 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 IMS measurements. All entries must have the same user-defined internal ID and the same user-defined system name. The jobnames must be the real jobnames of the IMS startup jobs.

With the IMS 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 IMS regions IMSMPP1, IMSMPP2, and IMSMPP3 are interpreted and calculated by Performance Management Assistant to one logical system IMS01. In the online dialog of PMA, 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 at the online panels for the specific transaction in system MRO as one line of information.

• To have multiple measurements a day for one IMS, you can define an entry for each measurement and determine the time range of the start of the measurement. Use different values other than from 00 to 24 only if you plan to measure an IMS region more than once a day. If you measure one IMS 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 APCIJINV accordingly.
