Modifying the batch application

When you make modifications to the application, be sure to save a copy of the original file. Modify a copy of an original file that has been renamed. Keep a backup copy of any original file and its modified version. This way, a new copy sent by IBM will not replace it.

Three modifiable model files are shipped with the product. They provide input to ISPF file tailoring, which in turn produces three files needed to run this application. One of these model files, DSQABB2J COPY, is the skeleton file behind the actual job sent to the CMS batch machine. In DSQABB2J COPY, you can modify the following:

• The account number
• The print and punch output limits
• The maximum processor time allowed for a job
• The name of the discontiguous shared segment (DCSS) on the ISPSTART command
• The SQLINIT statement to specify another database if queries are run in some database other than SQLDBA
• The links to the product disks

The two other model files do the following:

• DSQABB2P COPY creates the user's batch procedure.
• DSQABB2S COPY saves a user's query, form, and procedure and punches a job to the CMS batch machine. It also erases any work files that were created.
