RE: Maintain sub pools within Commons pool - is it possible

2016-01-28 Thread Krishnakumar Parasuram 
Hi Gruss
Bernd

Though it is REST framework, when it actually connects to our Siebel Server 
which connection object are maintained in the connection pool, it is no more 
REST, it is based on TCPIP

Hello,

You can programmatically create and configure pools at runtime. (At least if 
you skip container infrastructures). You can even dynamically register the 
pools in JNDI. I dont think you need sub-pools for this. (Subpools would be 
more interesting for partitioning connections by transaction or session state).

The only problem I see would be to access the dynamic pools from JPA persitence 
declarations, however thats a problem which is nkt really solved with sub-pools 
either.

Hi Jochen,

 

Thanks for your message.  The difference between to two separate pools is that 
in our framework we don't know exactly how many no of separate pool we might 
require, it is not two, but can scale more than 10, 20 in production 
environment and I think to have so many pools and that to we have to create 
dynamically at runtime, not practical

 

If it was a sub pool, I can always create the sub pool based on demand at 
runtime.  Moreover we have few parameters for each sub pool to maintain a min 
and max connection objects, which parameters can be different for each sub pool 
and cannot be implemented while design as we do not know these value of these 
parameters at design time.

 

Please let me know if this answers your question else let know

 

Regards

Krishnakumar

Could you please explain, what you have in mind technically? What
would be the difference between two separate pools, and
parent/subpool?

Thanks,

You might be able to accomplish your goals using a KeyedObjectPool. 
See the javadoc for that class.

RE: FW: Maintain sub pools within Commons pool - is it possible

2016-01-28 Thread Krishnakumar Parasuram 
Hi Phil,

Thanks for your message.  First , how do I respond to your message. I have 
added the dev@commons.apache.org in this mail.

I am already using the keyedObjectPool, but the keyedObjectPool give me only 
one level of grouping i.e if the Key->A then I can group all the connection for 
A, but I need two levels of grouping i.e.

The ObjectManger1 will contain the connection for A,B,C... so with the existing 
implementation if I query for the Key->A then I will get the connection under 
ObjectManager1->A connection,

But my requirement is I want to have groups like ObjectManager1 with A,B,C ...  
and

  ObjectManaer2 with A,B,C ...

  ObjectManager3 with A,B,C and so on

So when I request for a connection for A, I have the option to choose the A 
from ObjectManager1, ObjectManager2, or ObjectManager3 by selecting 
ObjectManagerX.

Is this kind of implementation possible?

Regards
Krishnakumar
