Control statements for the Reload task
The control statement block for the Reload task contains the user specifications for controlling the reload process.
Note: If REORGINPUT=ULDS is specified, see REORGINPUT control statement instead
of this topic.
Do not specify the COMPRESS and DATXEXIT control statements. The PARTINIT control statement is always ignored, even for HALDBs. However, a HALDB partition to which no segment was reloaded, is initialized regardless of the PARTITION INIT NEEDED flag in the DBRC registration. The DBRECDIST, RAPCHAIN, and PARTINFO control statements cannot be specified, and because the Reload task does not recognize keywords DBRECDIST, RAPCHAIN, and PARTINFO as control statements, these keywords do not show in the HPSIN Control Statements report (of the Reload task).
In parallel reorganization, DD name DFSUINPT specified in the INPUT control statement has a special meaning; the input identified by the DD name DFSUINPT is passed from Unload task directly.
Tip: If you specify PSINDEXBLD=NO in the (REORG) block, indexes are not
rebuilt in the job. Therefore, you must rebuild them in a separate index building utility job.
However, if you specify the WFPHLQ control statement in the (RELOAD) block, the IPR Reload utility generates WFP work data sets, which can be used as
input to IMS Index Builder jobs to rebuild indexes without
scanning the databases. You can also specify WFPSPACE, WFPUNIT, WFPVOL, and WFPVOLCNT control
statements to set attributes for dynamic allocation of WFP data sets.
The following table shows the control statements you can specify for the Reload task.
| Keyword | Acceptable values | Default | Description |
|---|---|---|---|
| BMSETDSG | n or (n1, ..., n10)
n=value or * |
* | Specifies the threshold value that is used to set the bitmap block. See BMSETDSG control statement. |
| BUFFERNO | 5 - 32767 | (None) | Specifies the number of database buffers that are used for one database data set group when reading or writing the database. See BUFFERNO control statement. |
| BYTELIMIT | DBD NOLIMIT nnnnnnnn |
DBD | Specifies the maximum number of bytes for a database record that can be inserted into the root addressable area. See BYTELIMIT control statement. |
| COMPAUTH | YES or NO | NO | Specifies whether to call the segment compression exit in supervisor state. See COMPAUTH control statement. |
| DBDSNAP | YES or NO | NO | Generates the DBD Snap report. See DBDSNAP control statement. |
| DBIOBUF | 1 - 999 | 30 (for VSAM), 15 (for OSAM) | Sets the number of VSAM/OSAM buffers. See DBIOBUF control statement. |
| DBRLBUF | 1 - 999 | 45 | Specifies the amount (the number of tracks) of database buffers that are used for one database data set group when reading or writing the database. See DBRLBUF control statement. |
| EXTENT | 1 - 120 | 120 | Specifies the maximum number of extensions of the OSAM data set that can be created. See EXTENT control statement. |
| FRSPC | YES or NO | YES | Specifies whether to secure free space factors or not. See FRSPC control statement. |
| ILEDATAC | data_class_name | (none) | Specifies the data class (DATACLAS) for HPSRILEA and HPSRILEB data sets. See ILEDATAC control statement. |
| ILESTORC | storage_class_name | (none) | Specifies the storage class (STORCLAS) for HPSRILEA and HPSRILEB data sets. See ILESTORC control statement. |
| INPUT | DFSUINPT, exitname, lang | DFSUINPT | Specifies the input data set, the user exit routine, and its type of language environment. In parallel reorganization, input data is passed from the Unload task directly. You do not need to code DFSUINPT DD in the JCL. See INPUT control statement. |
| OADSPR | YES or NO | NO | Specifies whether to reduce the usage of data space in processing (P)HDAM overflow area. See OADSPR control statement. |
| PAD | X'00' - X'FF' | X'00' | Specifies the padding character to fill out the segments to adjust to the length that is defined in the DBD definition. See PAD control statement. |
| PARTSTAT | YES or NO | NO | Specifies whether to print the Segment Count Summary report for each HALDB partition. |
| PROGMON | 0 - 999999 | 0 | Monitors the progress of the Reload task. See PROGMON control statement. |
| RAAFORMAT | YES or NO | YES | Specifies whether to format the HDAM RAA or not. See RAAFORMAT control statement. |
| RECNUM | nnnnnnnnnn | (none) | Specifies the number of unload records to reload. See RECNUM control statement. |
| REPAIRILK | NO or YES | NO | Specifies whether to reassign indirect list keys (ILKs). In reassigning ILKs, the IPR Reload utility uses new RBA, partition ID, and reorganization number. See REPAIRILK control statement. |
| SEARCH | integer value between -999 and 999, both inclusive | 3 | Sets the space search boundary. See SEARCH control statement. |
| SEQERROR | ABEND SAVE ACCEPT |
ABEND | Specifies how to handle key sequence errors. See SEQERROR control statement. |
| SORT | YES NO COND |
NO | Specifies whether to run physical sequential sort before the reload process. See SORT control statement. |
| SORTHIDAM | YES or NO | NO | Specifies whether to run the root key sequential sort process before loading HIDAM or PHIDAM. See SORTHIDAM control statement. |
| TWINSTAT | YES or NO | NO | Prints statistics about the twin chained segments in the Segment Statistics report. See TWINSTAT control statement. |
| WF1REC | YES or NO | YES | Specifies whether to create WF1 records that are written to the DFSURWF1 output work data set. See WF1REC control statement. |
| WFPHLQ | hlq | (none) | Specifies the high-level qualifier for WFP data sets. See WFPHLQ control statement. |
| WFPSPACE | CYL or TRK, primary_alloc,secondary_alloc | (none) | Specifies the SPACE parameter for WFP data sets when allocating WFP data sets dynamically. See WFPSPACE control statement. |
| WFPUNIT | unit_name | SYSALLDA | Specifies the device for WFP data sets when allocating WFP data sets dynamically. See WFPUNIT control statement. |
| WFPVOL | volume_name or * | (none) | Specifies the volume names for WFP data sets when allocating WFP data sets dynamically. See WFPVOL control statement. |
| WFPVOLCNT | nnn | (none) | Specifies the volume count for WFP data sets when allocating WFP data sets dynamically. See WFPVOLCNT control statement. |

Note: DBRLBUF and BUFFERNO are mutually exclusive.
