Submitting the GFTAXTR JCL for Concatenated Input

To submit the GFTAXTR job to concatenate input, you:

Copy the JCL member, GFTAXTRP, from SYS1.SAMPLIB
Change all references from GFTAXTR to GFTAXTD when making daily or weekly runs, and to GFTAXTF when making the final run. Then, change only the indicated fields
Submit the GFTAXTD or GFTAXTF JCL for execution using the TSO SUBMIT command

For more information on using JCL, see z/OS MVS JCL Reference.

GFTAXTD reads one input data set (SMFIN data set) and one input control statement data set (defined by the XTRCNTL DD statement) and builds a single output data set (XTRCIN data set) which can then be concatenated with other GFTAXTD runs to become the input for the final run (GFTAXTF). Make sure that the output from each GFTAXTD run has a unique name, such as RUN=RUN1, RUN2.

GFTAXTF reads one input data set (SMFIN data set) and one input control statement data set (defined by the XTRCNTL DD statement) and builds a single output data set (XTRCIN data set) which is used as input to GFTAVMA. To include all GFTAXTD data sets for the final run, add these statements after the EXEC statement:

//        EXEC GFTAXTF,SMFIN=,HLQ=...,RUN=...
//XTRACT.SMFIN DD DSN=your.data.set1,DISP=SHR
//             DD DSN=your.data.set2,DISP=SHR
//             DD DSN=your.data.set3,DISP=SHR

These statements nullify the SMFIN statement on the EXEC statement, and a JCL override DD statement, XTRACT.SMFIN, refers to additional data sets.

If you want to process multiple SMF data sets, then perform multiple GFTAXTD runs with each single SMF data set selected in the SMFIN DD statement. The output of each of these GFTAXTD runs is saved in the data set created by the XTRIN DD statement. When all of the GFTAXTD runs have completed for the selected SMF data sets, then perform a final GFTAXTF run.

The GFTAXTF run will use the GFTAXTD XTRIN output data sets in concatenation and specified in SMFIN DD statement to create the final XTRIN output data set that will be ready for a GFTAVMA analysis.

When you are processing just one SMF data set, use GFTAXTR to build a single output XTRCIN data set.
