Hello, I had installed Oracle EBS 12.1.1 on RedHat Enterprise Linux 64 bit. When i was trying to apply a patch i was getting error related to relinking, so I raised SR with Oracle. They suggested me to source my environment file and then execute adrelink.sh force=y "ad all" Now when i am trying to do adpatch a error message comes adpatchnew does not execute. Same is case with adadmin. Since adadmin is not working i am unable to take system out of maintenance mode. Can any one please help.
