Take-up JCL

Take-up JCL can be generated from the dialog. It is recommended that the take-up JCL is incorporated into your SMF Dump process. Sample job CPAHDB in library SCPASAMP provides an example of how to do this. Refer also to Example: Working with Shared Systems.

Step 1 is the SMF Dump process that reads online SMF MANx data sets (or other SMF data) and creates an extract data set of SMF records to be used for reporting purposes.

Step 2 is the CICS PA batch process that can perform the following tasks in parallel:
  1. Take-up to define the systems and SMF file to shared System Definitions.
  2. HDB Load requests to load performance data into Historical Databases.
  3. CICS PA Performance reporting to produce one of more reports for performance analysis.
Note that by combining take-up, HDB load and reporting into a single job step, all CICS® PA functions can be performed by a single pass of the SMF data.
