The DSNDB06 Database

Restriction: This topic applies to Windows environments only.

Every location contains a set of system catalog tables, stored in the DSNDB06 database. The system catalog contains the following security-related tables, which store various types of authorities and privileges:

SYSIBM.SYSDBAUTH (Database Authorization)
SYSIBM.SYSUSERAUTH (User Authorization)
SYSIBM.SYSTABAUTH (Table Authorization)
SYSIBM.SYSCOLAUTH (Column Authorization)

Provided that you have the necessary authority, you can query these tables in the same way you would query any data table.
