Schedule a batch job to issue top line LOAD commands at nonpeak processing periods and only LOAD a few jobs at a time.
The first time that CA WA CA 7 Edition submits a job or if the RELOAD option is Y on the DB.1 panel, a LOAD step is inserted and executes with the JCL. The LOAD step causes the defining to the database of the step, DD, and data set information within the JCL of the job. The execution of many LOAD steps can affect system performance and overall CA7ONL performance.
If you do not use the data set information from the database, you can turn off the adding of data set information. Use the LOADDSNS keyword on the DBASE statement in the initialization file. You can also set a job to never reload by placing an X in the RELOAD field on the DB.1 panel.
Note: XPJOBs and AGJOBs do not use LOAD processing because no data sets are created on the z/OS system.
Business Value:
This best practice produces quicker, more efficient processing of batch work.
