6.1.2 ASG-TMON for CICS TS for z/OS

 
ASG-TMON is an online CICS monitor. It records performance
data and file activity data for later batch analysis.
 
With releases 2.0 and higher of ASG-TMON, the record formats
changed.  The Transaction record (TA) has been updated to
reflect CICS/ESA and later measurements while dropping old XA
measurements that are no longer valid.
 
The TI record that, in previous releases was a system
interval summary, is now an accumulation of the data from the
transaction performance detail records (TA) for tasks that
ended within the time interval of the TI record.  There are,
however, some metrics on this record that do contain system
(region) level information. These include region CPU times
and DL/I resource usage.
 
It is very important that the intervals for the TI and TR
records be the same and something less than or equal to 60
minutes, for example, 60, 30, or 15, in order to populate the
CICS System Activity (CICCSY) file properly.  The data from
the TI and the TR records is merged together by an interval
timestamp.  If there is no matching TI record for a TR
record, the data from the TR record will be dropped.
However, CA MICS normalizes the end timestamp values from
both the TI and TR records in such a way that the end
timestamps will have an exact match in almost all cases.
 
Decompression Load Module Requirement for ASG-TMON
--------------------------------------------------
A decompression module is required to process ASG-TMON data
in compressed format.  You must either copy the appropriate
decompression module supplied by the vendor to
sharedprefix.MICS.LOAD, or concatenate the library containing
the module in DAY040's STEPLIB in the CA MICS DAILY job.
 
When copying the load module, ensure format compatibility;
the CA MICS load data set is delivered with a blocksize of
6160.  Using IEBCOPY with the COPY statement will not reblock
the module.  If the DCB attributes are different, use either
COPYMOD with IEBCOPY, or SAS PROC PDSCOPY to copy the
decompression module.

6.1.3 OMEGAMON II for CICS

The CA MICS Analyzer Option for CICS also processes the type
110 records written by OMEGAMON II for CICS.  The data is
recorded to SMF and is treated by CA MICS the same way as CMF
input.  A data dictionary record is required for each CICS
region being processed by CA MICS. For CICS 2.1, the type 110
records produced by OMEGAMON do not have the same format as
the CMF type 110 records.  Therefore, you must input either
the OMEGAMON data or CMF data in CA MICS, but never both.  An
abend in DAY040 during DAILY processing will occur if both
OMEGAMON and CMF records are encountered in input, because an
incorrect copy of the dictionary record may be used to read
the data records.  This problem does not occur in CICS 3.1.1
and higher releases.
 
The OMEGAMON type 110 record contains multiple user areas to
provide DB2, DL/I, and other database usage information.  The
DL/I user area contains data for both local DL/I and DBCTL
usage.  The CA MICS Analyzer Option for CICS automatically
decodes these user areas and populates the appropriate data
elements that are activated by OPTION OMEGU in the CICGENIN
member in the sharedprefix.MICS.GENLIB data set.

6.1.4 CICS Transaction Gateway SMF Type 111

The CA MICS Analyzer Option for CICS processes the SMF type
111 interval records generated by IBM's CICS Transaction
Gateway. The Gateway Server Activity (CTGGSA) file is created
from these SMF records and provides comprehensive information
about the activity and performance of each Transaction
Gateway address space.
 
Parameters within the IBM CICS Transaction Gateway control
both the recording of SMF type 111 interval records, as well
as the interval duration (default 3 hours), and the
end-of-day time (default 00:00:00 - midnight).
 
We recommend a minimum of 1 hour for interval duration, and
that the end-of-day time be set to 23:59:00 (1 minute before
midnight).  This will ensure that the correct interval
records are summarized into the appropriate HOUR as CA MICS
summarizes the CTGGSA file to the DAYS and higher timespans.
 
Refer to the IBM CICS z/OS Gateway Administration guide for
specific instructions on how to set these SMF recording
related parameters.
