Use the Ehcache version that comes packaged with with TC 3.7.x - I think its 2.6.x.

I have created a couple of Webcasts to help beginners get started

This one provides samples on how to scale.

In fact, I have sample TC Configs in my Githup site

https://github.com/lalithraj/BigMemory/tree/master/SampleTCConfig

This configuration comes out of the box with Terracotta. Just configure Terracotta with 1 stripe (each stripe consists of an active and mirror) and will give you the "HA" configuration you require

Perhaps someone else has a better answer but why are you rescheduling the same job. Simply create 2 one time jobs that form part of a mini-job cascading workflow and are interlinked. The second job only runs when your business condition is reached. Isnt that simpler?

AFAIK, OSS quartz doesnt handle this OOTB. You probably need to develop something custom for this, but yes, quartz can be configured to handle this.

I dont consider myself a hibernate expert but I found that you get the
org.hibernate.LazyInitializationException when you access what hibernate considers as child elements outside of the hibernate transaction boundaries. One of the tricks I used (in an earlier job) was to simply cache the POJO itself (outside of detaching the hibernate object).
HTH!

I dont understand your design. Why do you have 2 separate Terracotta Servers. If you want HA, that is inbuilt. Just have 1 stripe with an active and passive server as part of that mirror group.

Very tough to debug OOME issues with this info. There are no known issues that I know of Did anything change in your environment? Can you upgrade to the latest version of Ehcache?

Why are you shutting down the instance? Will that be part of your production scenario?

I am not sure of what you are asking but going forward, just use the Express mode. DSO is not longer supported

Its an internal JIRA - you cannot follow it. Just QA your "hack" until the fix is released. It should be out in 2.2.x

OSS Terracotta will be discontinued. See below.

Use free BigMemory Max free - it gives you upto 4 clients free.

You are correct. You need to set the batchTriggerAcquisitionFireAheadTimeWindow to a positive number to enable more than 1 trigger to be acquired.

This will be fixed in the next release. For now, just set the batchTrigger window to a positive number to acquire more than 1 trigger.

Correct - Security is an enterprise only feature. For more info, contact sales@terracottatech.com
