Analyzing the current workload

Break down the work to be done into transactions. Develop a profile for each transaction that includes:

Later, transactions with common profiles can be merged, for convenience into transaction categories.

Establish the priority of each transaction category, and note the periods during which the priorities change.

Determine the resources required to do the work, that is:

To determine transaction resource demands, you can make sample measurements on a dedicated machine using the CICS monitoring facility. Use these results to suggest possible changes that could have the greatest effect if applied before system-wide contention arises. You can also compare your test results with those in the production environment.

See Gathering data for performance objectives for more detailed recommendations on this step.
