Sorry for my broken english. This is what actually happening. I connecting HP-UX using SSH on my WIndows PC. I login with user id oracle before I using su root to get to root. I create a shadow file...
With my SSH, my HP-UX cannot login to root. It will come out a message su: unknown id: root. But I can login by user oracle. I also cannot login to console either by using root or oracle anymore....
