Requirements—Reorg function (Fast Reorg Facility/EP)
- Required. Install the Reorg function (with the prefix resolution and update function) and the versions of the Unload function, Reload function, and Index Build function included on the same tape. If you plan to use the Parallel Image Copy feature, you must install IMAGE COPY PLUS and the BMC load library from the same tape. If you want IMAGE COPY PLUS to invoke POINTER CHECKER PLUS to check pointers during the image copy, install POINTER CHECKER PLUS from the same tape. For instructions, see the the Installation System documentation.
Required. Prepare the databases for reorganization. Each database must be offline or in read-only mode. You can use the AOI feature of the Online Reorg function to accomplish this automatically.
If you are not using the AOI, issue a /STA DB dbdName ACCESS=RD command for each database to change the DBRC access intent.
Issue one of the following commands for each database that is to be reorganized:- If you specify SHARE(YES) to allow read access during the reorganization, issue a /DBD dbdName NOFEOV command for each database.
- If you specify SHARE(NO), issue a /DBR dbdName NOFEOV command for each database.
Issue the /DBD or /DBR commands in a separate step before the reorganization job step. If you specify AUTHERR(WTOR) in the Reorg function job step and you have not issued /DBD or /DBR commands for all databases or you did not use the AOI, the Reorg function issues messages stating which databases must be stopped.
- Required. Create and submit one set of JCL that runs the entire reorganization process. You can use your existing LOADPLUS, FRF, or MAXM Reorg classic JCL and add a few statements specific to the Reorg function. You also need to add IDCAMS statements to allocate the output data sets if you did not specify the IDCAMS keyword. For details, see JCL Requirements—Reorg function (Fast Reorg Facility/EP). The PLUSIN DD statement and the REORG command are required.
- Optional. If you want any special processing, set keywords in the PLUSIN DD statement. For an overview of the keywords, see the table in Keywords—Reorg function (Fast Reorg Facility/EP).
- Optional. If you have logical relationships, see Reorganization-for-logically-related-databases and Logically-related-databases1 for instructions.
- Required for a standard Reorg function reorganization; not valid if you specify INPUT(UNLDFILE). Swap the data set names. If you specified SWAP(YES), SWAP(DELETE), or SWAP(Y,IC) in the PLUSIN data set, the Reorg function automatically swaps the data set names. If you specified SWAP(YES) or SWAP(DELETE) in the PLUSIN data set and you reorganize a full-function database that has logical relationships, the Reorg function automatically invokes the prefix resolution and update function and swaps the data set names. To swap data set names manually, see Overview-of-Post-processing.
