Automatic cache clear for entity elements when doing CRUD operations?

[Kumaraswamy nandipati]

Hi.,

I am using cache for most of the times for entities (like
ProductCategoryMember, ProductCategory, Product, ShipmentMethod, etc.,) to
increase the application performance interms of database connections(hits).

Now question is
***When create, store or remove operations are done through the Entity
Engine, Does it be able to automatically clear any cache entries that might
contain the updated value???
*
Right now, its not happening to me. If I want to enable this feature, where
I need to change/edit the configurations. Please update me with the process
to implement this.

Thanks in Advance,

Hi Kumar,
UtilCache.clearAllCaches();
delegator.clearAllCaches();
The above methods will be your friends, but method is a shortcut to
completely clear all entity engine caches. For performance reasons this
should not be called very often.
But for sure other methods of UtilCache and delgator object will be of your
help.

Hi Rishi,

My previous question was not clear I think. Please *apologize* for this.
Here, I am writing in clear terms.

I am using 2 instances of ofbiz for one of my web application.
-First ofbiz instance points e-commerce module only.
-Second ofbiz instance used to represent all other modules(catalog, content,
partymgr, ordermgr, webtools etc.)

These two ofbiz instances hosted on different machines. Communications
configured by proxyPass calls at apache.

Here goes my problem, I enabled cache for retrieving ProductCategoryMembers.
Here, when ever I do any CRUD operations on this entity(i.e, *obiviously
happens in second ofbiz instance*), cache gets cleared for second instance
only. Its not getting cleared for first instance of Ofbiz. Otherwise I need
to wait for certain time on first instance(as per cache.properties file)
which is not relevant in this scenario.

To refresh cache in these two ofbiz instances at once what I supposed to do?
Is there any synchronization technique for this??

Hi.,

I am achieving this by using "Socket Connection" and streaming the
GenericValue objects which are need to be cache cleared in the other ofbiz
instance. Anyhow, there is no such strong cause to enable distributed
environment for OfBiz here, so, I chose "Socket Connection with Object
Streaming" decistion.

Please suggest me that, is there any other best way to achieve this??
