DD statements for the DEDB HASH Check option
To enable the DEDB Pointer Checker HASH Check option, you must specify in FABJMAIN JCL, the appropriate DD statements for the DEDB Pointer Checker HASH Check option.
The following table summarizes the DD statements for DEDB Pointer Checker.
| DDNAME | Use | Format | Required or optional |
|---|---|---|---|
| HISTORY | Output | LRECL=100 | Required if run with the HISTORY option |
| MSGOUT | Output | LRECL=133 | Required |
| REPORT | Output | LRECL=133 | Required |
| SNAPDPIT | Output | LRECL=133 | Required |
| SORTIN | Work | LRECL=12 | Optional if DEDBPC=S is specified |
| SORTOUT | Work | LRECL=12 | Optional if DEDBPC=S is specified |
| SORTWKnn | Work | Required | |
| SYSOUT | Output | Required |
The following DD statements are applicable when DEDBPC=Y or S is specified.
- HISTORY DD
- This statement defines the output data set that contains historical records. A historical record
is generated for each area if the HISTORY parameter is specified for the DEDBPC keyword.
For more information, see the IMS Fast Path Solution Pack IMS Supplementary Utilities User's Guide.
- 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.
