Block ping (this will test heuristics).
1. If node 1 is running the service, performing the following on node 1:
# tail -f /var/log/messages
2. On node 2 perform the following:
# iptables -A OUTPUT -d 192.168.1.30 -j REJECT
This will cause node 2 to fail the heuristics test and be declared dead to the cluster manager, which will
cause it to be fenced.
RECOMMENDATIONS
Congure cron job backing up Oracle embedded database. It is recommended that database backups be
performed at a regular interval to maintain integrity. It is advisable to schedule a cron job that performs
a database backup on a nightly basis for immediate recovery.
File system check of shared resources. Due to the shared resource mount points being employed, it is often
recommended that le system checks are performed on LVM partitions.
CONCLUSION
Combining the high availability features of Red Hat Cluster Suite with Red Hat Network Satellite provides
environments with a complete systems management tool with maximum up-time. The above procedure
demonstrates how Red Hat technologies can be combined and implemented in enterprise environment
to meet specic needs.
