DYNALLOC
The DYNALLOC keyword is valid with the BUILD, DBSCAN, RELOAD, REORG, GROUP, COPY, UNLOAD, and OREORG commands.
You can specify this option in the environment setup member (DLIGSET0) or in PLUSIN. The following table describes the Dynamic allocation keyword.
To do this | Specify this in PLUSIN |
|---|---|
Dynamically allocate the database data sets using the data set names specified in the RECON data sets. | DYNALLOC(YES) |
Do not dynamically allocate the database data sets. | DYNALLOC(NO) |
Dynamically allocate all database data sets using the data set names specified in the RECON data sets, and dynamically allocate output (shadow) database data sets with the data set name extension .Z (Online Reorg function and Reorg function). | DYNALLOC(YES,YES,Z) |
Dynamically allocate the output database data sets (valid only when INPUT(UNLDFILE) is specified in Reorg function). | DYNALLOC(NO,YES) |
Use only when INDD/OUTDD is not specified. Valid for full function databases and HALDBs. | DYNALLOC(N,Y,Z) |
Internal default: NO | |
The DYNALLOC keyword allows MAXM Reorg solutions to perform dynamic allocation as follows:
- Unload function—dynamically allocate the database data sets for the database being unloaded or scanned
- Reload function—dynamically allocate the database data sets for the database being loaded
- Index Build function—dynamically allocate database data sets for the database being scanned and the indexes being built
- Online Reorg function and Reorg function—dynamically allocate all necessary database data sets
When you specify the DYNALLOC keyword, DBRC must be active and all databases (including the index databases) must be registered in the RECON data sets. See DBRC-Index-Build-and-Reorg-functions. MAXM Reorg solutions use the data set names specified in the RECON data sets when allocating the database data sets.
If you do not specify DYNALLOC keyword or if you specify DYNALLOC(NO), you must include the database data sets in your JCL.
