Tomcat Load Balancing and jvmRoute's across multiple ser

Posted by christian.bryan@capita.co.uk on 01-Apr-2019 09:49

Hi All

I am experimenting with tomcat load balancing using PAS instances on multiple servers.

I understand that a part of the sticky session routing relies on the PAS / Tomcat instance name being appended to the Jsessionid so that load balancer can re-direct that session back to the correct PAS.

I can't see how or where you can control how that PAS instance name is set it looks like its based on your directory name e.g. if i created a PAS on one server as oepasForm i can't see to change its alias so that it appends anything other than oepasForm on the end of the sessionid.

This is an issue if i want to keep the same pas instance names across multiple servers.

Instead the only way i can get this to work with the LB and sticky sessions is to have unique PAS instance names on each server.

Am i missing something?

Thanks

Christian.

-N parameter controls instance name.
