If, when logging on to the database tools, you specify the user data as options, note the following minimum options:
· Database Manager GUI, SQL Studio
Specifying options is not required. These tools are started even if options are not entered, or if options are incorrect or incomplete. Database Manager GUI and SQL Studio always display a logon screen. In the logon screen, enter the user data required to log on to the database instance.
You need to connect to the database instance to use all of the functions of this tool. Enter the option -d <database_name> , if the database instance is on the local computer, and enter the option -n <server_node> as well if the database instance is on a remote computer. Further user data such as user name and password can be specified as options (for example -u) or, if required, as commands (for example user_logon).
If you do not specify the options required to log on to the database instance, or specify only some of them, or the details are incorrect, the Database Manager CLI is still started, and a connection to the DBM server is created, however, you are not logged on to the database instance. In this case, the Database Manager CLI can only be used to call DBM commands that are not related to the database (such as help, dbm_version, and so on).
If you call the Loader without options or only specifying the option -d <database_name>, you must enter the other commands to create a database session in the command file or interactively.
If you specify the option -b, the Loader expects the required commands in the command file. If you do not specify the option –b, the Loader is started interactively.
If you enter the options incorrectly, the Loader is not started, but a list of all possible options is displayed.
