Operating System Considerations

JCL Coding Considerations

Statistics reports can run either in local mode or under the central version. The JCL to run statistics reports appears in Appendixes A through D for z/OS, z/VSE and z/VM operating systems, respectively. The following considerations apply to coding the JCL for running statistics reports:

The input file containing the statistics records must be defined with ddname/filename/linkname SYS010 (the input file can be either the archived DC/UCF system log file or the output file produced by SREPORT 099).
When SREPORT 099 is run, the output file must be defined with ddname/filename/linkname SYS020.

Input File JCL Modifications

For the input file, modify the JCL in Appendices A through D, as follows:

For z/OS operations systems, modify ddname SYS010 in Appendix A as follows:
```
//SYS010  DD DSN=user.inputfil,DISP=OLD,UNIT=tape,VOL=SER=nnnnnn
```

user.inputfil	data set name of the archived system log file or SREPORT 099 output file
tape	symbolic device name of a disk or tape input file
nnnnnn	volume serial number of the input file

For z/VSE operating systems, modify filename SYS010 in Appendix B as follows:
```
// TLBL  SYS010,'user.inputfil',,nnnnnn,,f
// ASSGN SYS010,X'ttt'
```

user.inputfil	file-id of the archived system log file or SREPORT 099 output file
nnnnnn	volume serial number of the input file
f	file number of the input file
ttt	device assignment (channel and unit) for tape files (files may be disk instead of tape, in which case a device assignment, DLBL and EXTENT information are also required)

For z/VM and z/VM operating systems, modify the SYS010 command in Appendix C, as follows:

For input from the archived system log file:

For tape files: FILEDEF  SYS010 TAP1 SL VOLID nnnnnn
                         (RECFM VB LRECL 280 BLKSIZE bbbb

For disk files: FILEDEF  SYS010 DISK input file a
                         (RECFM VB LRECL 280 BLKSIZE bbbb

nnnnnn	volume serial number of the archived system log file
bbbb	block size of the input file
input file a	filename, filetype, filemode of archived system log file

For input from the file created by SREPORT 099:

FILEDEF  SYS010 DISK input file a
                (RECFM FB LRECL 280 BLKSIZE 8120

input file a

filename, filetype, filemode of archived system log file

SREPORT 099 Output File JCL Modifications

To create a file of statistics records using SREPORT 099, modify the JCL in Appendices A through D, as follows:

For z/OS operations systems, modify ddname SYS020 in Appendix A, as follows:

//SYS020  DD DSN=user.nonprint,DISP=(NEW,CATLG),
             SPACE=(TRK,(10,10)),UNIT=tape,VOL=SER=nnnnnn
             DCB=(DSORG=PS,RECFM=FB,LRECL=280,BLSIZE=8120)

user.nonprint	data set name for nonprint output
tape	symbolic device name of the nonprint output file
nnnnnn	volume serial number of the nonprint output file

For z/VSE operating systems modify file name SYS020 in Appendix B as follows:
```
// ASSGN SYS020,X'ttt'
// TLBL  SYS020,'user.nonprint',15
```

ttt	device assignment (channel and unit) for tape files (files may be disk instead of tape, in which case a device assignment, DLBL, and EXTENT information are also required.)
user.nonprint,15	file-id and retention period for nonprint/nonpunch output

For z/VM and z/VM operating systems, modify the SYS020 command in Appendix C as follows:
```
FILEDEF  SYS020 nonprint file a (RECFM FB LRECL 280 BLKSIZE 8120
```

nonprint file a

filename, filetype, filemode of nonprint output
