Jobs APCYJLST and APCYJLNA - Process CA MAT Measurement

After CA MAT has performed a measurement, CA MAT creates the List Dataset. Job APCYJLST evaluates the CA MAT measurement that resulted from generated measurements. To get the measurement, a program must be called. Job APCYJLNA contains a procedure to do so. Additionally, a program is called to interpret the measurement. Performance Management Assistant saves or discards a measurement depending on the consumption during the step's execution, user defined parameters, and alert reasons. The measurements are kept or deleted as determined by the deete processed sample ds parameter. Job APCYJLST automatically creates and submits APCYJLNA jobs as many times as needed to process all measurements.

Job APCYJLST has the following scheduling considerations:

• Execute early in the morning after the nightly batch runs have been completed. It is also important that the job is not started too soon, which allows Performance Management Assistant to collect more measurement information.
• If you are also using the CICS Feature or IMS Feature, make sure that CICS or IMS measurements have been completed. These are provided by jobs APCCJINV and APCIJINV respectively.
• There should be at least one execution per installation per day.

In order to get the measurement results available in Performance Management Assistant as soon as possible, the Server submits job APCYJLNA any time a measured job step has terminated. If you use this functional benefit, job APCYJLST is needed only for measurements that are not controlled by Performance Management Assistant and for the CICS and IMS/DC measurements.

Since all measurements of CICS or IMS/DC regions must be processed in one APCYJLNA job, job APCYJLST must be provided with the names of the regions. CICS and IMS/DC add monitor invokes for CA MAT. CA MAT creates List data sets from the Monitor data sets and these List data sets are interpreted by job APCYJLST for the regions identified in the following members:

• To identify all CICS regions:

  APCJCIC  DD  DSN=CAMAT.PMA.CNTL(APCCCINV),DISP=SHR  
  

• To identify all IMS regions:

  APCJIMS  DD  DSN=CAMAT.PMA.CNTL(APCICINV),DISP=SHR
  

  The JCL for job APCYJLNA is found at DDNAME INTUPROF of job APCYJLST. It is input to the internal reader. Make sure that the job card of APCYJLNA is customized to fit your environment.

  You can choose any kind of rename for the sample data set, for example, for a test installation.
