Operational Considerations

The output records of IRRDBU00 are determined by the structure of the RACF® database. The utility unloads all profiles in the database. It does not unload all fields in each profile and treats some fields in a special way. Fields containing customer data are unloaded exactly as they appear in the database. Encrypted and reserved fields are not unloaded.

Although the maximum length unloaded for most fields is 255 bytes, all 1023 bytes of data for the FSROOT, HOME, and PROGRAM fields in the user's OVM segment are unloaded.

For the conversion rules of the database unload utility, see z/VM: RACF Security Server Macros and Interfaces.

The database unload utility uses the class descriptor tables (IBM-supplied and installation-defined) as it unloads profiles. If your database is imported from another system, you may also have to import the class descriptor tables (ICHRRCDX and ICHRRCDE). Classes will be unloaded only if there is an entry for them in ICHRRCDE or ICHRRCDX on the system running the utility.

To correlate the RACF profiles with the data unloaded by the utility, see z/VM: RACF Security Server Macros and Interfaces.
