Are there any SMF record layout changes between CA IDMS R18 and R19 of IDMS?
No, there are no changes to the SMF record layout between CA IDMS release 18.0 and 19.0
however there are a couple of CA IDMS 19.0 PTFs that correct reported problems.
RO89206 Title: INC03 - IDMS INCREMENTAL RELEASE 3 ( EFFECTIVE: MAY 13 2016)
INC03 - SMF4/30 MESSAGES WRITTEN AS 230 RECORDS
This PTF adds an additional parameter to #PMOPT that allows SMF
Type 4 and Type 30 records to be written either with or without
the additional Performance Monitor header.
The possible parameter values are:
SMFHEDR=YES - Default setting. The Performance Monitor header will
be attached and SMF Type 4 and 30 records will be
written as a type matching the SMFRCID field in
#PMOPT (default Type 230).
SMFHEDR=NO - The Performance Monitor header is not attached to
SMF Type 4 and 30 records.
In releases prior to 18.0 SMF Type 4 or Type 30 records
written by Application Monitor did not contain the additional
Performance Monitor header.
If 'SMFHEDR=YES' is used, PMSMFEX can be used to extract SMF Type 4
or Type 30 records.
RO84146 Title: PERFMON SMF HEADER SAYS 1800 FOR 18.5 AND 19.0
(EFFECTIVE: SEP 15 2015)
The 4-character release number which PERFMON inserts into an SMF record
header is being set to '1800' for releases: 18.0, 18.5, and 19.0.
SMF header records generated by PERFMON contain the characters '1800'
as a version number in the header.
PERFMON records extracted from SMF records by the Culprit program
PMSMFEX contain '1800' in the PERFMON header.
Programs which process statistics by release are unable to distinguish
19.0 statistics from 18.0 statistics from 18.5 statistics.
