ORA-LOGIN indicates the user name under which you want to connect to the database system.
Example
To connect to the database with the user name MYNAME, you would specify:
ORA-LOGIN MYNAME
in the configuration file.
If ORA-LOGIN is not set, the runtime will attempt to do an automatic login for you. For autologin to succeed, you must have set up an account OPS$USER where USER is the same as your computer login name.
