SMF decompression (DM1495)

Problem summary
**************************************************************** * USERS AFFECTED: All users of DB2 Version 10 for z/OS who * * generate compressed DB2 SMF records. * **************************************************************** * PROBLEM DESCRIPTION: This PTF provides a SMF decompression * * sample program. * **************************************************************** * RECOMMENDATION: * **************************************************************** In DB2 Version 10 for z/OS, the subsystem parameter SMFCOMP can be used to turn on compression of DB2 SMF records. The default value for SMFCOMP is OFF. This PTF adds DSNTSMFD to V10. DSNTSMFD is a DB2-supplied sample application for decompressing compressed DB2 SMF records. It accepts an SMF data set in standard SMF format and produces an output SMF data set. All SMF record types are accepted, but only compressed type 100 (DB2 Statistics), type 101 (DB2 Accounting), type 102 (DB2 Performance) records generated by DB2 are decompressed. All other records (including uncompressed DB2 records) are copied unchanged to the output SMF data set. ============== About DSNTSMFD ============== DSNTSMFD can process input SMF records that contain records from up to 512 DB2 subsystems. DSNTSMFD accepts SMF records from any release of DB2. Only systems with the z/OS CSCESRV macro available will be able to use DSNTSMFD to decompress records. Only compressed SMF records from DB2 V10 and beyond are eligible for decompression. DSNTSMFD produces an end-of-job summary, which is written to the SYSPRINT DD: * Total SMF records read * Total DB2 records read * Total DB2 compressed records read * Total DB2 compressed records decompressed * Total non-DB2 records read * Aggregate size of all input records * Aggregate size of all input DB2 records * Aggregate size of all input DB2 compressed records * Aggregate size of all output DB2 records * Aggregate size of all DB2 expanded records * Aggregate size of all non-DB2 input records * Percentage saved using compression * Details of records by DB2 subsystem The SYSPRINT DD is also the destination for diagnostic and warning messages generated by DSNTSMFD. DSNTSMFD requires the following DD statements: * SMFINDD (input) The SMFINDD DD must specify one or more data sets that contain DB2 trace records in standard SMF format. All SMF records are acceptable, but DSNTSMFD will only attempt to decompress SMF type 100, 101, and 102 records. * SMFOUTDD (output) The SMFOUT DD specifies the output data set. Non-type 100, 101, and 102 SMF records are written to this data set; if the decompression service (CSRCESRV) is not available, the compressed records are copied and a warning message is produced. * SYSPRINT (output) Contains the end of job summary report plus diagnostic messages for any DSNTSMFD processing exceptions. All messages are documented in the DB2 for z/OS Messages manual. ================ Running DSNTSMFD ================ DSNTSMFD is designed for execution in the z/OS batch process. It has no dependency on DB2 other than as a source of the SMF records. =================== Sample job DSNTEJDS =================== For convenience, sample job DSNTEJDS provides the basic JCL framework needed to assemble and execute DSNTSMFD. DSNTEJDS is not intended to be run as part of the DB2 Installation Verification Procedure (IVP). Note that DB2 does not provide sample SMF records. See the DSNTEJDS prolog for directions on how to customize it for use at your site.
