oracledb resource takes a long time to stop and reports a timeout waiting for processes in RHEL 5 or 6 High Availability clusters with Oracle 11g

Issue

• The resource agent oracledb.sh is not working properly. Every operation that involves the offline of this resource incurs in a timeout
• When I stop an oracledb resource, it always reports a timeout waiting for processes to stop:
