This product update forwards updates to both software and documentation.
The software update is Release 9.1.0 of CPExpert. The release number
indicates that it is the first release of 1999.
This release (1) provides support for OS/390 Version 2 Release 7 (V2R7),
(2) provides enhanced data selection/reporting options and additional
analysis for the CICS Component, (3) provides additional performance
analysis for the WLM Component, (4) enhances the documentation for
the DASD Component, (5) provide updated documentation on CD-ROM, and
(6) corrects errors that have been reported.
OS/390 Version 2 Release 7.
OS/390 V2R7 was made Generally Available (GA) by IBM at the end of
March. Since Computer Management Sciences is a Partner in
Development with IBM, I normally can provide support for new
releases of MVS within 30 days of GA of the new IBM release.
Update the CICS Component.
The CICS Component has been updated in the following areas:
Update the WLM Component.
The WLM Component has been updated in the following areas:
Add an option to extract only CICS interval statistics files and
variables that are required for analysis of CICS performance
constraints. This option is suitable for sites with extremely
large CICS performance data base.
Add an option to exclude listing of the SIT and rules that are
"turned off" by the CICS Component. This option is suitable for
sites that analyze a very large number of CICS regions and otherwise
might have an undesirably large output from the CICS Component.
Add an option to suppress the analysis and findings of particular
rules, or suppress the analysis and findings only for particular CICS
regions. The desire for this feature typically is caused by (1) an
overall disagreement with the finding, (2) an inability to make a
suggested change, or (3) a decision that a particular finding is
not applicable to a particular CICS region.
Revise the process for specifying guidance for CPExpert to analyze
the TCLASS times at MAXACTIVE.
Add options to analyze the tasks active in a CICS region, as
controlled by the MXT keyword in the SIT.
Add an option to specify unique analysis guidance for individual CICS
regions. This option applies to any user who analyzes multiple CICS
regions during a single execution of the CICS Component. The various
CICS regions typically provide service to different users, the regions
often have different applications, and the regions may even be a
mixture of test regions and production regions. One set of analysis
guidance variables do not always apply to all regions being analyzed.
Consequently, CPExpert now provides the capability to override the
basic guidance on a region-by-region basis.
Add a new rule to analyze whether the Maximum Task (MXT) specification
may be too small.
Add a new rule to analyze whether the Peak EDSA usage is approaching
the EDSALIM value.
Update the DASD Component.
The DASD Component has been updated in the following areas:
Add a new rule to analyze situation when Execution Phase samples for
CICS transaction service class data did not exist in SMF Type 72
records (Work Manager/Resource Manager section).
Add a new rule to advise that the response performance goal may be
Add a new rule to advise that a service class was capped for
discretionary goal management.
Add a new rule to advise that non-DASD I/O activity or delay was
Add a new rule to advise that non-paging DASD I/O activity caused
Correct the code to account for errors discovered in IBM's
Provide documentation on CD-ROM.
This release provides all updated documentation to reflect references
for OS/390 Version 2 Release 7.
Add a description of techniques that are used to generate an IOCP
input data set, using the Hardware Configuration Definition (HCD)
component of MVS.
Add documentation of Rule DAS102 and Rule DAS202 to describe the
rules that have been a standard part of the output (but had been left
out of the User Manual).
Revise the description of installing the modification for MXG if
either the MXG BUILDPDB or SAS/ITSV is used to process SMF data.
The CPExpert documentation is
accessible via Adobe Acrobat Reader, and the CD-ROM contains a free
copy of Adobe Acrobat Reader. The Adobe Acrobat Reader should be
installed on your PC under Windows 3.1, Windows 95/98, Windows for
Workgroups, or Windows NT. Installation of the Reader will require
about 6 megs of space on your hard drive.
There is no additional charge for the CD-ROM versions of CPExpert
documentation. If any user does not have the capability to access
documentation on CD-ROM (or simply prefers to have hard-copy
documentation), please give me a call.
Correct errors that have been reported.
I've added a new member in the CPExpert code titled
GENERR82) which contains a listing of the errors that were
discovered in CPExpert code for Release 8.2, and an acknowledgment
of the user who found the error.
I really appreciate calls from users reporting problems or simply asking questions.
As I said in the original delivery letter for CPExpert, if errors occur with your
please don't waste your time trying to solve the error.
Just give me a call and I will quickly fix the problem!
I suggest that you use the following steps to install Release 9.1.0:
Create a new PDS titled "prefix.CPEXPERT.V91.SOURCE".
Create a new PDS titled "prefix.CPEXPERT.V91.USOURCE".
Install CPExpert into the "prefix.CPEXPERT.V91.SOURCE" using the normal
installation procedures described in the CPExpert Installation Guide.
Copy your old USOURCE members into "prefix.CPEXPERT.V91.USOURCE".
This step should be done so you do not have to recreate all of your unique
parameters. There are no changes to the variables in USOURCE members,
unless you are exercising new options provided with this code.
If you elected to receive updates to CPExpert on a diskette, the software is
distributed on the CD-ROM that contains the CPExpert user documentation.
I have created a BAT file for you so that you can easily upload the new
software. This file is titled "UPLOAD.BAT" and will be located in the
SOFTWARE directory of the CD-ROM. The BAT file was created per your
instructions (i.e., using SEND, etc.).
I would like to say "Thank you" to the following individuals. These folks have
discovered errors, proposed new features, or suggested documentation changes since
the last Update Bulletin:
I particularly appreciate the support provided by users who sent me
data to analyze! While IBM provides data to me (as a part of the
Partners in Development program), it is invaluable for me to have
data from the user community. CPExpert analysis gets better mostly
by users providing data that I can analyze, identify performance
problems, devise solutions, and develop code to automate the process

Please visit my web site (www.cpexpert.com) for information about CPExpert. I post
answers to frequently answered questions, list errors reported by users for the
current release of CPExpert, and provide information about CPExpert components that
you might not license.
Additionally, I've posted several papers on the web site that I've
presented at professional conferences.
Please call, fax, or send me a note on the Internet if you have suggestions, you want
new features, or you would like to see more or different reporting done by CPExpert.
