    Hi,

    >> here i am unable to login through sysdba

    >> when i enter the password it says invalid username and password

    Which command are you using... please post it here... normally if you are on the same machine and in the dba group you don't need to enter a password.

    >> if i login with nolog and connect /as sysdba it takes me in too.

    Please post this procedure, too.

    Regards

    Stefan

    • Hello,

      >> sqlplus

      >>user-name = sysdba

      >>password = default password

      This is wrong. The "sysdba" is not a user... it is a privilege..

      You can connect with sqlplus "/ as sysdba" directly from the shell.

      If you don't specify a user (which is done with "/ as sysdba"), you authenticate with the OS user and the dba group.
