Title :                   Restore Limited CPU Timer Support

(Short description of what you want the product changed to - include keywords like function, short product name)

Statement of the Problem :    (What?  Detailed description of what you want changed, 400 char.limit)

 

Restore support in the STXIT macro for the cpu timer.  Restrict timer support to the BG partition.  This support was formerly available, but was removed due to a

conflict if the timer was allocated to a CICS partition (if I recall correctly).

                                                                                             

  Benefit :    (Why?  Non-technical business case description, i.e a business case. Do not reword problem statement above. How do you to justify the needed change?  Wwill itrequest benefit the submitter’s your company, and the vendor and others? Business case and benefits to users and vendor which can to justify the needed change?.  Quantify: run time, dollars, manpower, etc. Also, wWhy should is it important for vendor to want to do this for their customer?s)

 

The cpu timer is the most reliable way to time processor performance benchmarks.

Use of other approaches (such as using the low resolution interval timer) produces

inaccurate results.  Use of benchmarking programs allows us to measure the

performance improvement offered by new processor models relative to our company's job mix and also permits us to verify the efficiency of inhouse code.

  Date :       (When?  ASAP, 6 months, one year from now, etc) 

next release

  Impact :    (How?   How will your company’s business be affected if a solution is not delivered.)

 

Estimating processor performance under changing workloads  - in advance - will

continue to be more a matter of educated guesses rather than actual measurement.

 

  Solution :  (optional desired / undesired elements Note: suggest can limit vendor ability to deliver a solution)

 

Do not change JCL - limit cpu timer support to the Background partition only.

  Classification :  (Suggestion=Nice Idea, Long Range=Future, Tactical=ASAP, or Acceptability=I won’t buy the product or will drop the product if solution not provided)
