Strobe for IMS overview

Strobe is a product that determines where and how time is spent in online applications and batch processing programs. Strobe produces a collection of reports that help you determine how to revise applications to improve their performance.

Strobefor IMS extends the functions of Strobe. With Strobe for IMS, you can measure IMS DB- and DC-dependent regions and evaluate the performance of the following:

• Online DL/I (Data Language/One) applications that execute in Message Processing regions (MPRs), IMS Fast Path regions (IFPs), or Batch Message Processing regions (BMPs)
• Batch DL/I applications (DLBs)
• DL/I applications that access IMS from a CICS/DBCTL environment (when Strobe for IMS is used in conjunction with Strobe for CICS).

You can also measure and evaluate the performance of IMS system modules in the following:

• Control region (CTL)
• DL/I Separate Address Space (DLISAS).

This section describes the benefits of Strobe for IMS, provides an overview of IMS/ESA, and introduces the Strobe Performance Profile for IMS regions.
