How to Use

Use an alternate (additional) SYSIN with a DBUTLTY DEFAULT function to control certain defaults. Execute the DEFAULT function using the following command format:

►►DEFAULT ─┬─ INIT_IXX_BLKSIZE=nnnn ─┬──────────────────────────►◄
           └─ INIT_IXX_OLDEP=NO ─────┘

Command

DEFAULT

Invokes the function to control certain defaults.

Use no blank before DEFAULT when you specify it in columns 1-7. Follow DEFAULT with one blank (and use no continue lines).

Required Keywords

INIT_IXX_BLKSIZE=nnnn: INIT_IXX_BLKSIZE=nnnn gives you the ability to specify a user default nnnn for the block size during an INIT function with AREA=IXX used to initialize an index area (IXX or multiple data set index).
INIT_IXX_OLDEP=NO: INIT_IXX_OLDEP=NO gives you the ability to specify a user default for the Old Entry Point support for an index during an INIT function with AREA=IXX used to initialize an index area (IXX or multiple data set index). Only INIT_IXX_OLDEP=NO can be specified. The DBUTLTY default of YES is not valid for the DEFAULT function.

Example

In the case of an INIT_IXX_BLKSIZE=nnnn, the INIT of an index area (INIT AREA=IXX) allows an optional keyword of BLKSIZE= that can be specified as numbers from 4096 through 8192. The DBUTLTY default is 4096 or less, optimized for the device type containing the data set. If you want to replace the default with your own default of, for example, 5555, you could use an additional SYSIN with the following statement:

DEFAULT INIT_IXX_BLKSIZE=5555

For every DBUTLTY execution using this additional SYSIN, if an INIT is done with an AREA=IXX that does not have BLKSIZE= specified, it is given the user default of BLKSIZE=5555.

Consider the following:

The DEFAULT function allows you to override this default. Therefore, if you provided a statement INIT AREA=IXX,BLKSIZE=8182, for that one INIT, the index would be initialized with a block size of 8192.
An individual function has no path to requesting the normal default.
The additional SYSIN can be overridden for any step by having a JOB/STEPLIB pointing to a different DBIN1PR module.
If the DBIN1PR module indicates a data set, the additional SYSIN can be overridden for any step by having a DD statement pointing to a different input.
All DBIN1PR input is echoed to the console without an option, for example: DB10096I - DBIN1PR PROCESSED - DEFAULT INIT_IXX_BLKSIZE=5555.
The use of a default does not force an error.
