The -gu database server option controls who can execute file administration statements. You can use this option to specify which users are able to execute certain administration tasks. See -gu server option.
There are four levels of permission for the use of file administration statements:
|-gu option||Effect||Applies to|
|all||Anyone can execute file administration statements||Any database including utility database|
|none||No one can execute file administration statements||Any database including utility database|
|DBA||Only users with DBA authority can execute file administration statements||Any database including utility database|
|utility_db||Only the users who can connect to the utility database can execute file administration statements||Only the utility database|
To prevent the use of the file administration statements, start the database server using the none permission level of the -gu option. The following command starts a database server and names it TestSrv. It loads the mytestdb.db database, but prevents anyone from using that server to create or delete a database, or execute any other file administration statement regardless of their resource creation rights, or whether they can load and connect to the utility database.
dbsrv11 -n TestSrv -gu none c:\mytestdb.db
To permit only the users knowing the utility database password to execute file administration statements, start the server by running the following command.
dbsrv11 -n TestSrv -su secret -gu utility_db
The following command starts Interactive SQL as a client application, connects to the server named TestSrv, loads the utility database, and connects the user.
dbisql -c "UID=DBA;PWD=secret;DBN=utility_db;ENG=TestSrv"
Having executed the above command successfully, the user connects to the utility database, and can execute file administration statements.
