Hi,
We have 2 tomcat servers running behind load balancer and the SSL terminated
at the LB. So far I have working set up of CAS with Ehcache and I could see the
cache being populated/replicated between the 2 nodes. I followed the steps
provided in following wiki page for Ehcache ticket registry :
https://wiki.jasig.org/display/CASUM/EhcacheTicketRegistry
I would like to set up our environment for HA. I would like to know if the
configuration specified in the wiki page enough for making CAS HA with Ehcache?
Is there something else that I need to configure to make CAS HA?
I have attached the ehcache-replicated.xml and the ticketRegistry.xml for our
environment for reference.
Thanks,
Rakesh
