There are changes to CICS® monitoring and statistics data that could affect user- and vendor-written utilities that analyze and print CICS SMF monitoring and statistics records.
Check your utility programs that process CICS SMF records to ensure that they can process the SMF 110 records correctly. If you have utility programs provided by independent software vendors, you should ensure that these also are able to handle the SMF 110 records correctly.
You can identify SMF 110 records from different releases by using the record-version field in the SMF product section.
Some performance data fields are added to performance class data records. The result of all these additions is that record length of performance class data records has increased significantly, with the maximum record length now up to 1836 bytes per record.
To avoid flooding your SMF data sets with unwanted data, and consequently filling them too quickly, you can reduce the amount of data written to SMF by using a monitoring control table (MCT) to selectively include or exclude specified fields. See the CICS Resource Definition Guide for information about coding an MCT to control data recording using the DFHMCT TYPE=RECORD macro.
For details of all new and changed monitoring fields, see the CICS Performance Guide.
