The job submission facility collects statistics, generates reports, and executes actions (utilities). We recommend that you become familiar with extract, execution, action, and report procedures. This section contains the following information:
  • Submit - Build JCL Parameters Information
  • Displaying Extract Options During Batch Submission
  • Submission Messages and Codes
  • Submit a Procedure in Batch Mode
  • Customize Execution
  • Recommendations for Procedure Execution
The submission facility revolves around the Submit-Build JCL Parameters panel. From this panel, you can perform the following tasks:
  • Execute a procedure in batch mode.
    • For batch submission, a JCL job is created and submitted to JES for batch execution.
    • For a batch data set, a JCL job is created in a specified data set. You can execute this job at any time or can have it automatically submitted by a job scheduling system.
  • Control which actions, Db2 objects, and reports are executed. You can customize an extract, report, or execution procedure for a specific execution. The contents of the procedure are changed for the execution only.
    For example, you can specify that you do not want to invoke any action procedures tied to an extract procedure. The action procedure connections are severed only for that execution run.
  • Specify the number of concurrent scans to perform during the collection process. If you specify more than one concurrent scan, statistics are collected on multiple Db2 objects concurrently.
  • Specify the number of read-ahead buffers to use for storing VSAM pages from the Db2 objects during processing.
  • Request that progress messages be sent to the system consoles. These messages help the operator monitor the progress of a procedure execution.
The submission process is consistent for all procedures.
