Notes:
1 You can specify any number of input (INDD) and output (OUTDD) data sets for the SMF dump program, IFASMFDP. The input files are dumped in reverse order unless concatenated under one input file. For example, in Figure 21, two input files are specified. After the IFASMFDP program is processed, the output file (user.SMF.DATA) contains the records from INDD2 first, followed by the records for INDD1. Although you probably code the INDD parameter and the associated DD statements to process the data sets in chronological order, the DFHSTUP program produces a correct report if you fail to do so.
For further information about unloading SMF data sets, see the z/OS MVS System Management Facilities (SMF) .
2 The OUTDD parameter refers to an OUTDD1 DD statement defining a disk data set. To rerun this job you need to change the DISP parameter to DISP=(OLD,KEEP). The TYPE parameter specifies the full range of SMF record types, causing IFASMFDP to unload all records. If you want to select only CICS records, change the record type parameter to TYPE(110). Unloading all the CICS SMF 110 records in this way also includes the SMF 110 records from journaling, monitoring, and the CICS Servers (temporary storage, coupling facility data tables and named counter). The DFHSTUP program only process CICS SMF 110 records with record subtype 2, all other SMF 110 records are ignored. If you want to unload just these CICS statistics records processed by DFHSTUP, change the record type parameter to TYPE(110(2)).
3 The DFHSTUP program sorts statistics records in the sequence: specific applid, date (in YYYYMMDD form), and time.
4 The ddname for the input to the DFHSTUP program must be DFHSTATS. This input is the unloaded SMF data set.
5 The ddname for the DFHSTUP work file must be DFHSTWRK. There are six types of statistics records that can be written to the DFHSTWRK data set:
The size of the DFHSTWRK data set required will depend on the largest set of resources, from the above list, being written to the data set.
The following calculation can be used to estimate the size of the DFHSTWRK data set required:
6 The DFHSTUP program sorts the data by means of a link to the MVS™ sort program, DFSORT, to ensure that data is correctly processed in chronological sequence. These sort work files are needed by the DFSORT program.
7 The ddname for the output from the DFHSTUP program must be DFHPRINT, which you can direct either to a data set or printer.
8 The control parameters for the DFHSTUP program can be supplied only in the SYSIN data set.
Each control parameter in the SYSIN data set should start on a new line and is terminated by a blank. If you need to continue a control parameter for more than one line, you must ensure that the line to be continued ends with a comma in column 1 through 71, there is a non-blank character in column 72 of the line to be continued, and start each continuation line in column 16. For example:
//* Column 16 v 72 v
SELECT APPLID=(CICSIDA,CICSIDB,CICSIDC,CICSIDD,CICSIDE,CICSIDF,CICSIDG,/
CICSIDH,CICSIDI,CICSIDJ)
COLLECTION TYPE=ALL
The available parameters are described in Control parameters of the DFHSTUP program.
