I am new to Oracle (coming from a SQL Server world). This is going to probably be some simple newbie question. I just did a fresh install of Oracle 12c Express. The install was successful, but now I can't, for the life of me, figure out how to log in.

According to Oracle's documentation, I should be able to log in using SYSMAN as the username and the password I entered during installation. I have tried to log into the web interface. It says Login denied; invalid username/password. I also tried to log in using Oracle SQL Developer and had the same issue. Finally, I tried logging in using SQL*Plus from the command line. Same issue.

Can someone please tell me how to initially log in after a fresh install of Oracle 12c?

  • first question would be, did you create a database or just install the oracle software? Jun 4 '15 at 8:37
  • try 'SYSTEM' user Jun 4 '15 at 13:50
  • @davegreen100 - Yes, I installed both.
