Required Options 

If you do not enter all the required user data as options, or if you were unable to log on to the database instance with that user data, the SAP DB tools will react as follows:

·        Database Manager GUI, SQL Studio
Entry of 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.

·        Database Manager CLI
Only some of the options required to log on to the database instance were entered, or they were incorrect. The Database Manager CLI starts and you are connected to the DBM Server. 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 (for example, help, dbm_version).
You need to connect to the database instance to use all the functions. 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 transferred as options (for example -u) or, if required, as DBM commands (for example user_logon).

You should always start the Database Manager CLI by entering the options -d, -u and, if required, -n when calling the tool (Options (DBMCLI)).

·        LOADERCLI
The minimum required option -d <database_name> for logging on to the database instance and the required option -b <command_file> for specifying the command file were not entered at all, were incomplete, or incorrect. The loader is not started, but displays a list of all possible options.
Log on to the SAP DB Loader again by entering the required options.
Further user data (such as user name and password) can be transferred as options (for example -u) or, if required, as commands (for example use_user).

When you call the tool, you should always start the SAP DB Loader by entering the required options -d and -b (Options (LOADERCLI)).
