Usability improvements have been made to the statistics fields in System Management Facilities (SMF) records on z/OS. The record field names have been enhanced to more easily identify fields. Also, in some sections, more fields have been added to report additional information.
To log statistics records in SMF or to a sequential data set on z/OS, you must specify the STATS statement in the DBMOVER configuration file. Include the SMF parameter to write statistics records in SMF, or include the FILE parameter to write statistics records to a sequential data set.
If you previously logged SMF statistics records to a sequential data set on z/OS, perform the following tasks after you upgrade to 10.1.1:
Create a new data map for accessing SMF statistics records. The new data map must reflect the new record layout. You can use the updated pwxstat.file data map in the
PowerExchange 10.1.1 installation
\examples\datamaps
directory.
Remove the existing sequential data set to which you logged SMF statistics in the previous release. PowerExchange cannot access records of the old format based on the new data map.
Allocate a new sequential data set for SMF statistics. Ensure that the data set is large enough to accommodate the new larger record sizes. For variable length, blocked data sets, the following DCB allocation attributes are usually sufficient: LRECL 5000 and BLKSIZE 27998. Then specify the data set name in the FILE parameter of the STATS statement in the DBMOVER configuration file.
Also, if you have been using SMF statistics records programmatically, verify that the PowerExchange 10.1.1 record content and format changes do not disrupt your programmatic use of these records.
