Optimization in production

This section provides procedures for putting the Optimizer into production.

Overview of optimization in production

Before you begin optimization on all data streams in your CICS system, you might want to perform some testing on SUPEROPT. Initially, you might not want to optimize every data stream in your CICS system. If every data stream is not optimized, optimization statistics for SUPEROPT will not be a good indication of the statistics when optimization is performed for all data streams.

For more information about the Erase Input key, see Using.

Selective optimization

You might want to begin selective optimization of certain optimization techniques or to begin optimization of a particular terminal, Transid, or selected group of terminals or Transids. To turn on optimization gradually (after installation has been completed), start with just one Termid and test until you are confident that everything is working as expected. Add a selected group of Termids or Transids (using include/exclude) and test until you are comfortable with the results. Then, remove all excludes or includes that have restricted data stream optimization.

Turning on optimization for one Termid

Summary: In this task, you will turn on optimization for one Termid (after installation has been completed).

To turn on optimization for one Termid, perform the following steps:

1. Issue the Transid that you have chosen, and enter the Monitor.

   The Initialization Options panel is displayed.

2. Select option 1 to enter the Monitor.
3. The Primary Menu is displayed. The Optimizer is not started, but you can view the Monitor panels.

4. To optimize the data streams for just one terminal, type =1.1.1.

   The Global Optimization Control panel is displayed.

5. Include just one Termid.

   Warning

   Note:

   If this terminal is local, turn on optimization for locals from the Local Terminals and Saved TIOA panel, option 1.3.5.

   Message BMC7099I, Optimizer Includes/Excludes changed, is displayed.

6. Press F3 to return to the Primary Menu. The Primary Menu is displayed.
7. Start the Optimizer. The Optimizer status is Active.

8. Test as many transactions as you can from the one Termid, and verify that everything works as it should.

   Transaction results should be as expected.

   Warning

   Note:

   If transaction results are not as expected, contact BMC Software Customer Support.

Turning on optimization for a select group of Termids or Transids

Summary: In this task, you will turn on optimization gradually (after installation has been completed) for a group of Termids or Transids.

After testing from one Termid, select option 1.1.1 and turn on optimization for a select group of terminals or a select group of Transids by performing the following steps:

1. Enter a generic Termid, or create a table of Termids to include the terminals.

2.  Enter a generic Transid, or create a table of Transids to include the Transids.

   Warning

   Note:

   To create a Termid or Transid table, see Using.

Optimization statistics

When you have determined that no problems remain, remove all excludes or includes that have restricted the data stream optimization. You can begin to monitor the optimization statistics for SUPEROPT.
