CRUISE should allow the aggregation of smaller tables into one large super table or a table of tables

CRUISE should allow aggregation of smaller tables into one large super table or a table made up of other tables. This would allow multiple tables to be run as a single job from start to finish.
Instead of taking REF-ID parameters as input, the Super Table (or System Table) would take other CRUISE Tables as arguments. These tables would then be run serially. When one completes the next one would be started. Appropriate status and completion messages would be displayed at the start and end.
This could be restricted just to CAPTURE or could also be allowed for a VERIFY function.
For the “CAPTURE”, one common set of BFA tapes would be generated. However, there would be a marker or separator record between the end of one individual table and the start of the next. This will allow the RESTORE to work in stages. Each individual table would be restored from start to finish before reading the next set of data records from the BFA tape.
This will result in smaller XREF files and keep them from getting too large and needing a very large allocation. This will improve the performance of the file address exchange phases of the restore (FAD EXCHANGE). When one table restore is finished the XREF files would be initialized.

    Brand - Servers and Systems Software
    Product family - z Systems Software
    Product - z/TPF

    For recording keeping, the previous attributes were:
    Brand - WebSphere
    Product family - Transaction Processing
    Product - z/TPF

    We feel that a lot the functionality described (running multiple CRUISE tables serially) can be achieved today using automation. One of the benefits described is to have smaller XREF files to improve performance. We believe we can make a change to improve the performance of processing the XREF files that will apply to all of CRUISE processing, not just when it is desired that multiple tables are run. We would include that as part of RFE 4908, which specifically targets how CRUISE cross-reference files are allocated and used. The biggest part of the requirement that would not be addressed is the request for a common set of BFA tapes to be used to process multiple tables.

    Due to resources and priority, IBM does not intend to do this in the forseeable future.
