1. Re: Clustered CMP Entity Bean
darranl Jul 21, 2003 6:35 AM (in response to masj)As I understand it this feature is not available in any of the production releases of JBoss at the moment.
I know that there was talk of entity bean replication being implemented but I am not sure how far it has got. -
2. Re: Clustered CMP Entity Bean
masj Jul 22, 2003 3:42 AM (in response to masj)If there is no support for clustered entity beans in JBoss, does anyone know how one usually does to achive a similar behaviour?
I have implemented something that I would like to call a hack: calling a BMP entity bean which inserts/updates/deletes the data on all servers in the cluster. It must be possible to do this some other way?
MySQL, which I am using, does not support active-active replication, could this otherwise be used to solve the problem?

3. Re: Clustered CMP Entity Bean
darranl Jul 22, 2003 10:13 AM (in response to masj)I have heard that using a distributed database with active to active replication could quite easily lead to more problems.
The databases will queue up the requests to be replicated and it can aparently be quite easy to start working with old data on a different node. -

sdev Jul 23, 2003 9:21 AM (in response to masj)Is it possible to cluster a Entity Bean that uses CMP and CMR. If so in which version of jboss.
Thnks in Adv. -

Does any version of JBoss support Clustering for an Entity Bean that uses CMP and CMR. -

slaboure Jul 27, 2003 11:07 AM (in response to masj)You never have notions of "clustered entity beans" where the actual state is clustered: this is always delegated to the DB (check with BEA, WS, etc.) Sometimes you can get a distributed cache (such as the one in the forthcoming 4.0). in 3.x, entity beans have clustered proxies, not state.
