DD statements for the DEDB HASH Check option (DFSUDMP0 JCL)
These DD statements are used only if you enable the DEDB Pointer Checker HASH Check option through the HASH exit of the Image Copy function.
| DDNAME | Use | Format | Required or optional with the HASH Check option |
|---|---|---|---|
| MSGOUT | Output | LRECL=133 | Required |
| REPORTS | Output | LRECL=133 | Required |
| SNAPDPIT | Output | LRECL=133 | Required |
| SORTIN | Output | LRECL=12 | Optional |
| SORTOUT | Output | LRECL=12 | Optional |
| SORTWKnn | Work | N/A | Required |
| SYSOUT | Output | N/A | Required |
- MSGOUT DD
- This statement defines the output data set for DEDB Pointer Checker messages.
- REPORTS DD
- This statement defines the output data set for the Pointer Chain Reconstruction report of the DEDB Pointer Checker. The data set can reside on a direct-access device or printer, or be routed through the output stream.
- SNAPDPIT DD
- This statement defines the output data set for the DEDB CI map or CI dump report. The data set can reside on a direct-access device or can be routed through the input stream.
- SORTIN or SORTOUT DD
- These DD statements define the work data sets used for the subset pointer check function of the DEDB Pointer Checker. If you want to use the data space for the subset pointer check, or if you do not want to use the subset pointer check function at all, you can omit these DD statements.
- SORTWKnn DD
- These DD statements define the intermediate storage data sets used by DFSORT. For more information about SORTWKnn DD statements, see DFS Application Programming Guide. Allocating a space twice the size used by the SORTIN data set is usually adequate for each work data set.
- SYSOUT DD
- This statement defines the output data set for DFSORT messages.
