Overview of defining the QPF option

QPF is a very flexible tool that can be tailored to address the specific requirements of each IMS system in your environment. This is done by setting the QPF options to fit your needs. However, the flexibility of the product also means that setting the QPF options is a complex task that requires you to analyze each of your IMS systems. Additionally, you need to understand the purpose of each QPF keyword and the implications of the values that you set for each keyword.

This section describes a methodology that you should employ to analyze your IMS systems, develop a plan to resolve identified problems, and build a QPF_OPTIONS command set to implement the plan.

The following subjects are discussed:

• Analysis and planning methodology

  BMC Software recommends that you use the methodology discussed in this section when analyzing your IMS systems and developing a plan to address identified problems.

• Defining QPF options

  A test case is provided as a step-by-step illustration of the analysis and planning methodology. The test case takes you from historical analysis through testing of a QPF_OPTIONS command set.

• Testing a QPF_OPTIONS command set

  Two Message Advisor test applications are provided with the product. You can define the test applications to simulate the conditions that cause the queue overflow problems described in the test case. If you are running a trial of the product or you have just installed it, testing the QPF_OPTIONS command set created in the test case will illustrate how QPF manages message queues.
