Hello Saad, If the adjusting permissions is not very helpful, could you check if the free space on the filesystem is not the issue. I vaguely remember having encountered this (low space on either home directory of the oracle id, ORACLE_HOME directory OR dest directories for udump/bdump) a while back and preventing sqlplus connections. Does the alert log show anything ? -Rajeev On Tue, May 19, 2009 at 10:43 AM, Saad Khan <saad4u@xxxxxxxxx> wrote: > Good Morning fellows, > > Thanks. > > Sid >
