To work with a database instance, to make data queries or to manage the database instance, you have to open a database session. This can happen as follows:
· The user logs on to the database instance with a user name and password, thus opening a database session. Later, the database session is terminated explicitly by the user or closed implicitly when the timeout value is exceeded.
· A database tool implicitly opens a database session and then closes it again later.
To open a database session implicitly, the Database Manager uses the data for the first DBM operator. For this reason, only those database statements for which the first DBM operator is authorized can be executed.

to display database information, or the

Assistant for liveCache instances.
