Specifying the input database

Allowable ddnames for the data sets corresponding to the input database are INDD1 through INDD255. The input data sets must be numbered consecutively. For example, if 25 input data sets are provided, they must be assigned ddnames INDD1 through INDD25. The utility processes the input data sets until a number is omitted. You must provide at least one input data set (INDD1). Specify the real names of the data sets; do not specify aliases.

The only considerations in ordering the input data sets (that is, which data set you assign to INDD1, which to INDD2, and so on) are the following:

The utility copies the ICB, templates, and segment table from the input data set defined by INDD1 to all output data sets.
The ICB of the master primary data set contains the setting of the current RACF® options. If you want these options copied, INDD1 should be the master primary data set.
If you do not allow duplicate names in the DATASET class or if duplicate entries exist within any other class, the utility copies the entry from the input data set identified by the lowest-numbered ddname.
Ensure that each input data set is correctly formatted for the RACF database.
The IRRUT400 utility does not copy empty data sets; the index must contain valid profile entries for the utility to copy the data set.
