Session Replication in Tomcat 9

[Samee Mir]

Dear Team,

I have a couple of linux app servers having tomcat 9 installed and we have configured the memcached servers on the same servers configured has node 1 and node 2 in a cluster.

Everything is working fine except when we have to bring down one of app server lets say for the maintenance.  The sessions on that nodes are lost as there is no session replication.

We are using load balancer without session afinity before the app servers.

We are using kony product and as per my discussion with the vendor they are saying memcache doesn't  have a mechanism to replicate the sessions of node 1 on node 2 for HA.

Can someone help me to confirm I cant do the session replication  using memcached or there could be a way?

 

Appreciate your help on this.

Regards,

Samee
