Following the update of the Oracle databse or running some oracle scripts, an error occurs ORA-27140: attach to post/wait facility failed
To resolve the problem, please check the 'Sticky bits' on the oracle binary ($ORACLE_HOME/bin/oracle)
How to:
# cd $ORACLE_HOME/bin
# ls -l oracle*
# chmod 6755 oracle
# chmod 6755 oracleO
# chmod 6755 oracleO
After that check:
# ls -l oracle*
