[jboss-user] [JCA/JBoss] - re-authentication and pooling

[dimonv]

Hello,

I have seen several topics in the JCA forum discussing different issues, which could be solved by the re-authentication feature. I guess in our situation this is also the case.

We are using a third party JCA resource adapter providing connections to the CORBA services. The CORBA services have different interfaces. We have to authenticate the user requesting a connection and using then the  authentication mechanism:

  | <security-domain-and-application>
  | 

which causes that the connections are pooled by the Subject and their types. Now regarding the connection pool size. For example:
500 application users (different identities)
70 different connection types
20 max pool size (each sub-pool)
1 min pool size (each sub-pool)

The result of this scenario is that the pool can grow up to 500*70*20=700000 connections.

Well, at the moment our pool size do not achieve this level, but the number of application users tend to grow.

Considering this scenario the re-authentication would allow to have just one common pool for all connections and re-use them for every identity.

I would very appreciate if the re-authentication is considered by the pooling implementation in JBoss. Since JCA does not restrict the number of the types/interfaces of the connections provided by a resource adapter, I can imagine that there could be many other resource adapters and their users, which will surely benefit from this feature.

Thanks and kind regards,
Dmitri
