The tibdg Commands to Set Permissions on a Table
When data grid permission checking has been enabled, by default, tables created by using the tibdg create table command do not have permissions set on them, meaning no users can have access to the data in the table. Only after users or roles are granted permissions on the table, are users able to read or write data in the table.
The tibdg tool offers two options, grant and revoke to control the permissions given to a user or a role. For convenience, the grant and revoke commands support granting all permissions to a user or role, which is the equivalent to granting or revoking both read and write permissions.
Permissions can be granted to or revoked from a specific user or a role. If a permission has been granted to a role, then any user with that role has that permission.
