My application runs on two servers. The existent traffic is 15 tps per server. Also it uses terracotta 2.7.2 server as an active and a passive(hot standby). Two client applications run by connecting to Active terracotta server.
My Installations are :
Virtual Machine : Java HotSpot(TM) Server VM version 11.0-b16
Operating System: SunOS 5.10
Number of processors: 64
I am newbie for tc and need to learn that :
When terracotta server is upgraded from 2.7.2 to 3.4, what should it be done? For example : i detect that dso-boot jar file should be created for new jdk version(1.6.24) by using make-boot-jar.sh. Is there any other requirement? can there be any risky situation? Also my application is on production and there should not be any risky situation.
I'm responsible for product which has been developed via DSO and use terracotta server 2.7.2. We have got some problems cause tc server 2.7.2 so we need to upgrade it from 2.7.2 to tc server 3.4.0 with the smallest change through it is very critical.
1) Could you please explain basic difference between DSO and Express Ehcache?
2) Is Express Ehcache commercial product?
3) Is terracotta server 3.4 backward compatible?
