Reduce CPU utilization by TPFDF data collection

TPFDF open/close routines in UBC0 collect data for ECB resource monitor, CDC, and TPFDF data collection. These collections run constantly but are rarely used. A switch to control these counters would reduce CPU utilization by TPFDF.

Enhance TPFDF Data Events Specification CollectOpen to be a parameter for collectionType=Subfile

collectOpen at the <lrecIncludeAll> or <lrecIncludeList> level means all LRECs in the database must be accounted for if the collectionType = Subfile. If LRECs are added to the database, then the EVSPEC must be kept in sync.

DFDL Generation for JAX-B Processing

Currently the DFDL generated out of the “zudfm decsriptor file-xxxxxxxx” in such a way that when run through JAX-B to generate a Java objects called DFLREC, which contains members for each LREC in the database. The LRECS are generated a single mem...

CRUISE Restore BFA tape roll-in should allow read from multiple drives concurrently

The CRUISE Restore tape roll-in should allow tape reads from multiple drives concurrently. CRUISE should have the option to use more than one tape drive concurrently for the BFA tape roll-in phase. The tape drives can be kept stacked with tapes so...

TPFDF should utilize the RIAT

IBM Standard TPFDF uses generic prototypes for all TPFDF applications per any given pool type. SHARES uses TPFDF for roughly 75% of the database. Using IBM TPFDF standard, hundreds of millions of records per day would issue GET on the same record ...

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 Sup...

Provide a means for CRUISE to recover from a hang or deadlock condition

Provide a means for CRUISE to recover from a hang or deadlock condition. A running CRUISE table has the potential to hang or get stuck in a sort of deadlock situation. The maximum allowed ECB's have already been created. One or more ECB's may need...

CRUISE should provide a facility to execute functions at the system level, e.g. full system CAPTURE

Provide new system level functions, e.g. CAPTURE type. This would scan through the entire ID range from the beginning to the end, to chain-chase each of the ID's in the DBDEF table. This is similar to what RECOUP does. Providing functions for syst...

Enhance the CRUISE cross-reference file processing and handling options

There are several considerations in how the CRUISE cross-reference files are allocated and used. In addition to the need to improving the performance which has been addressed in other RFEs, there are other enhancements that would provide more flex...

Allow CRUISE to reallocate TPFDF database primes using Capture / Restore procedure

To reduce pool chaining in a highly accessed TPFDF database we would like to reallocate the prime records from their 1K face type to a 4K face type.The CRUISE RESTORE can only restore records to the original FARF addresses used by the CAPTURE proc...
