Database-administrator privilege

The highest level of database privilege is database administrator, or DBA. When you create a database, you are automatically the DBA.

Holders of the DBA privilege can perform the following functions:
  • Execute the DROP DATABASE, START DATABASE, and ROLLFORWARD DATABASE statements.
  • Drop or alter any object regardless of who owns it.
  • Create tables, views, and indexes to be owned by other users.
  • Grant database privileges, including the DBA privilege, to another user.

Only the user informix can modify system catalog tables directly. If you are user informix, IBM® strongly recommends that you not modify the contents or schema of any system catalog table, because such actions can affect the integrity of the database.
