EXEC statement—JCL requirements
The EXEC statement for each utility except the Index Build function and the Prefix Resolution/Update function uses the same format as the EXEC statement that is used for the IMS utilities.
It calls the region controller DFSRRC00 and specifies a ULU region. DBRC parameters can be included on the EXEC statement. You can add the IMSID parameter to override the IMSID specified in the IMS RESLIB.
The MAXM Reorg solutions do not run as an IMS dependent region.
EXEC statements by command
Command | EXEC statement |
|---|---|
REORG (Online Reorg function and Reorg function) | PGM=DFSRRC00,PARM='ULU,DFSURGL0,dbdName' dbdName is the name of the database being reorganized. |
COPY (Copy function) | PGM=DLICPYON |
UNLOAD (Unload function) | PGM=DFSRRC00,PARM='ULU,DFSURGU0,dbdName' dbdName is the name of the database being unloaded. |
RELOAD (Reload function) | PGM=DFSRRC00,PARM='ULU,DFSURGL0,dbdName' dbdName is the name of the database being reloaded. |
BUILD/BUILDALL (Index Build function) | PGM=BMCSIU |
Prefix Resolution/Update function |
|
Image Copy function | The Image Copy function runs under the Online Reorg function and Reorg function only; it cannot run as a stand-alone utility. |
CLONE (Clone function) | PGM=DLIGENTR |
The JCL requirements are similar for all MAXM Reorg solutions. The functions use the commands shown in the following table.
Commands
Function | Command | Description |
|---|---|---|
Online Reorg function | REORG | Reorganize a database while updates are being made by an online IMS or CICS/DBCTL system by using the Reorg function, the Unload function, the Reload function, the Index Build function, and the Image Copy function. |
Reorg function | REORG | Reorganize a database by using the Unload function, the Reload function, and the Index Build function. Prefix resolution and update is also integrated for logical relationships. |
Copy function | COPY |
|
Unload function | UNLOAD | Unload the records in a database. |
Unload function | DBSELECT | Retrieve selected records from a database. For more information, see Database-Selection-facility. |
Unload function | TRACE UNLOAD USERREAD | Use the API. For more information, see API—Unload function. |
Reload function | RELOAD | Reload the records in a database. |
Reload function | SORT | Sort unloaded records before reloading them by using the stand-alone HD Sort utility. For more information, see HD-Sort-utility. To sort and reload a database, specify the HDSORT keyword with the RELOAD command. |
Reload function | USERLOAD | Use the API to load a database initially. For more information, see API—Unload function. |
Index Build function | BUILD BUILDALL XFLD XSCN XLOD | Build indexes (primary, secondary, or both) for a database. The BUILDALL, XFLD, XSCN, and XLOD commands are converted to a BUILD command automatically. |
Index Build function | SPLIT | Split the WF1 file and write index records to one file and logical relationship records to another file. |
Image Copy function | IC AIC | Create output image copies during the database reorganization process. Keywords are specified in the ICPSYSIN data set. |
Image Copy function | GLBL GROUP | Set global and group options for the Image Copy function. Keywords are specified in the ICPSYSIN data set. |
Clone function | CLONE | Create an internally consistent copy of a database or a list of databases. |
