Setup of distributed cache clear

[Nicolas Mervaillie]

Hi,

I'm currently working on the setup of a load balanced OfBiz infrastructure :
x Apache HTTP servers, x Ofbiz instances, x db instances (just load
balancing, no fail-over through session replication).
Everything goes just fine, the OfBiz installation is a breeze.

OK. Then I change a product label on one of the instances through the admin
tools. The modification does not apply on the other instances (they keep
displaying the cached label).
I guess I have to setup the jms service and the entity engine to handle the
cache invalidation but I didn't find any documentation/posts on this
subject.
I played around with the distributed cache and JNDI parameters without
success so far.

=> Does I need an external JMS server ? How to setup the JNDI services in
OfBiz ? How to setup the entity engine ?

=> In order to get the full system working, are there any issues I am not
aware of ?  (pool configuration for job execution ?)

Any help appreciated.
Thanks in advance.

Quick answer : did you have a look at, distributedClearCacheLineBy* services ?

For the pool(s), as long you don't want to explicitly set it on sepcific server(s) there should not be any problems.

Oops, I meant distributedClearCache* and  distributedCache* (search for strings)

Of course, this does no mean that you could experienced problems if you do so. It's the goal !

Hi Jacques

Thanks for the reply.

Yes, I did have a look to the distributed cache parameters.
Activating the distributed cache causes a JNDI lookup problem on the JMS
connection factory (which seems normal : no JMS server activated and
registered on startup)
I tried to setup the JMS service and register it in JNDI but with no
success.

In fact, what I don't get is that the JMS service use a different JNDI
context (OpenJMS InitialContext)
How does this JNDI interact with the "standard" OfBiz JNDI context ?

About the pools : do you mean that even if I have several OfBiz instances,
no more than one instance will execute a given job ?

No time for that for the moment...

Yes, job status is used for that.
