Do you encounter either of these errors --
- unable to attach to shared memory segment
- unable to determine size of shared memory segment
Check permissions on your $ORACLE_HOME/bin/oracle file. You may need to set the sticky bit.
First, run an ls -l $ORACLE_HOME/bin/oracle.
It should look like this --
openlink> ls -l /$ORACLE_HOME/bin/oracle -rwsr-s--x 1 oracle dba 33692568 Aug 18 2009 oracle
If it does not, use the chmod command to alter the permissions like this --
chmod 6751 oracle
