Strobe for IMS benefits

Strobe for IMS obtains measurement information to produce the Strobe Performance Profile, a series of reports that provide the following:

• Show CPU activity and wait by load module and control section
• Attribute CPU activity and wait to DL/I requests within application programs
• Identify CPU activity in online DL/I applications by IMS transaction (for Message Processing regions) or by routing code (for Fast Path regions)
• Identify DL/I activity by IMS transaction for all IMS regions running within the IMS subsystem being measured.

Strobe for IMS lets you identify the DL/I application programs and transactions that most affect the performance of your IMS system. Additionally, you can determine which IMS system modules execute on behalf of those application programs and transactions. Using this information, you can decide how to do the following:

• Streamline application code to request DL/I services more efficiently
• Concentrate performance improvement efforts to reduce CPU activity and wait resulting from DL/I database service requests
• Divide transactions across Message Processing and Fast Path regions
• Distribute hardware resources more effectively.

Strobe for IMS identifies CPU activity in IMS system tasks within the Control and DL/I regions by dynamically assigning them pseudo-transaction names.
