Question

How do I know which version of ThingWorx is stable?

I have come across several (diverse) issues with the ThingWorx Platform which seems mainly related to the H2 version, but I have also found problems with the PostgresSQL version.

I always use Ubuntu 14.04 LTS since it is certified and the prescribed versions of Java, Tomcat and PostgresSQL.

I appreciate that there is a lot of development and we all contribute towards logging issues and squashing bugs.

However, when needing to deploy a production build, how do we know which version and combinations of Java / Tomcat / OS is MOST stable?

This becomes even more challenging if we start adding extensions and the EMS.

I would appreciate some guidance or even a rule of thumb if someone has found one that is reasonably reliable.

Thanks!

Not for now,

We had been stick on 6.5.13 for one year and a half, and doing a lot of tests in order to move on 7.X for 6 months - starting at 7.0, we expect to move on 7.3.3 when it's released....

Neither 6.5.13 on Neo4j was super stable, Yesterday we moved on 6.5.3 PostgreSQL

Thanks Charles,

Can you elaborate on OS, PSQL, Tomcat and Java versions that you are running on 6.5.3?
