You can access and communicate with the database instance from the Database Manager administration tool.
If you do not specify a database user for a command for accessing the database instance, the first DBM operator is used as the system default.
You can access the database instance as follows:
Access using a database session
Access using a service session
Note the server authorizations required for the respective DBM commands.
A database or service session must be opened to execute the DBM commands. For more information, see the descriptions of the individual DBM commands.
