SecuritySQL Statements for User Management

Fine-grained System Privileges

In addition to granting users full administrative privileges, system privileges make it possible to grant regular users a subset of administrative privileges that have historically been limited to SYSDBA and administrators only.For example:

Run utilities such as gbak, gfix, nbackup and so on
Shut down a database and bring it online
Trace other users' attachments
Access the monitoring tables
Run management statements

The implementation defines a set of system privileges, analogous to object privileges, from which lists of privileged tasks can be assigned to roles.

It is also possible to grant normal privileges to a system privilege, making the system privilege act like a special role type.

The system privileges are assigned through CREATE ROLE and ALTER ROLE.

Warning

Be aware that each system privilege provides a very thin level of control.For some tasks it may be necessary to give the user more than one privilege to perform some task.For example, add IGNORE_DB_TRIGGERS to USE_GSTAT_UTILITY because gstat needs to ignore database triggers.
