We collect the SMF70,89 records throughout the month and submit a Subcapacity
Report each month based on MSU usage; we generally save a few dollars each
month.
We must report on all LPARS defined to our processor; in our case a production
LPAR and a test LPAR.
Our SCRT eligible products are:
"z/OS V1","5694-A01",33
"CICS TS for z/OS V3","5655-M15",33
"MQSeries for z/OS V6","5655-L82",33
"IBM Enterprise Cobol for z/OS and OS/390 V3
In our installation parameters for SCRT Release 19.2 the following IMS products
are eligible for SCRT:
EDIT BDC2.SCRT.V19R2M0.NO89 237 lines dele

000001 * IMS DATA COLLECTOR FOR WEBSPHERE STUDIO APPL MONITOR V3
000002 * TIVOLI COMPOSITE APPLICATION MANAGER FOR IMS V6
****** **************************** Bottom of Data ************************
Suggest install the current SCRTool, collect the data over a month and see what
you get...
If the rolling average for MSU utilization in a given month is lower than the
licensed capacity of your processor you may save a few dollars each month...

Subject: Re: Running a SYSPLEX - what's needed
Thanks for all the responses here and offline. Here are some answers to
questions about our environment:
- The 2096-T01 is our only processor. We are running z/OS 1.11.
- We do not currently use sub-capacity processing. We do not submit monthly
SCRT reports.
- The T01 runs at 100% every night for 10 hours.
- The IMS address space and MPRs are up from 6AM-8PM daily. These address
spaces average LT 3% utilization during this time. The peak for a 30 minute
interval is almost always under 5%.
- There is a small amount batch IMS during the nightly cycle (after 8PM).
- We run IMS TM/DM. Some IMS TM also use DB2.
- We currently use CA-MIM when the TECH LPAR is up - not GRS.
- IMS DM and TM are currently under EWLC pricing.
The main IMS application is critical to our business. It is not scheduled to
be replaced for at least 5 years.
Several folks commented off-line that if we only use a single CEC there is no
possibility of savings.
Planning for Sub-capacity Pricing on z/OS indicates the sub-capacity pricing
metric operates at the LPAR level. I did not see anything about CEC
limitations. Did I miss something?
Are there any small shops out there that have been successful at controlling
IMS costs by creating a separate 'IMS LPAR'?
Thanks for the responses.
