SYSTEM.INSTALLAUTH lists all users and authorization groups that have been granted INSTALL authority. ALLBASE/SQL updates SYSTEM.INSTALLAUTH when processing a GRANT INSTALL or REVOKE INSTALL statement, or when dropping a group having INSTALL authority.
SYSTEM.INSTALLAUTH, SYSTEM.COLAUTH, SYSTEM.MODAUTH, SYSTEM.PROCAUTH, SYSTEM.SPACEAUTH, SYSTEM.SPACEDEFAULT, SYSTEM.SPECAUTH, and SYSTEM.TABAUTH, contain the security scheme for the DBEnvironment.
CATALOG.INSTALLAUTH is identical in format to SYSTEM.INSTALLAUTH; it permits users without DBA authority or SELECT authority on SYSTEM.INSTALLAUTH to examine rows to which they have access.
