It;s better not to cross post whenever possible...

Not sure to ask your question, but a good starting point would be Red
Hat Documentation main page:
https://access.redhat.com/knowledge/docs/Red_Hat_Enterprise_Linux/

Some of RHEL 6 guides:
Security-Enhanced Linux
Managing Confined Services (with SELinux)
SystemTap Beginners Guide
SystemTap Tapset Reference

and there are many others related to Virtualization, Clustering,
Resource Mgmt (Control groups), Identity Mgmt...

Tipically they are a very good starting point and are well written.
Don't forget that you can also submit a Documentation Bug, so that you
can participate in improving documentation itself for others

Then you can buy for example JBoss Developer subscription for less
than 100$ / year and experiment (it includes the OS and RHN access):
https://www.redhat.com/apps/store/developers/jboss_developer_studio.html

Or go through CentOS if the budget is a constraint for you or you want
to try all the possible technological solutions (Cluster, Cluster
Storage, XFS, ecc..).
