      ORA-12547: TNS:lost contact

      The env has been set and everything worked yesterday, but today when i try to connect with this user i get this error. I read that relinking all could solve this problem, but the thing is we cant shut down database now so i have to find another way.

      i can connect with other users from oracle user but not with this user, and yeah i can connect with application user too. As i sad, something went down south today, because yesterday everything was normal.
