Ok, a few days ago I posted a question about managing the size of databasepools ( with JBoss 2.4.3). My Tests for it doesn't work...
Now I'm using JBoss 3.0.0. In the default-configuration there is the Hypersonic database "default", which I think is managed by JBOSS-SYSTEM:service=ConnectionFactoryLoader,name=DefaultDS.
ConnectionManagerFactoryLoaderName JCA:service=ConnectionManagerFactoryLoader,name=MinervaSharedLocalCMFactory
ConnectionManagerProperties

MinSize=0
MaxSize=3
BlockingTimeoutMillis=5000
IdleTimeoutMinutes=30
CleanupIntervalMinutes=10
MaxIdleTimeoutPercent=1.0
JndiName: DefaultDS
ManagedConnectionFactoryProperties
ConnectionURL=jdbc:hsqldb:hsql://localhost:1476
DriverClass=org.hsqldb.jdbcDriver
UserName=sa

ResourceAdapterName
ResourceAdapterName
State 3
StateString Started
TransactionManagerName java:/TransactionManager
In this MBean I found:
ConnectionManagerProperties
and there you can set the MaxSize.
(In the actual Docu is written: MaxSize. The maximum number of managed connections in the pool. Requests beyond this will block => so I think only "MaxSize" Connections could be established to the database).
So I tested, whether Database-Connections will be blocked, if the number of connections equals the MaxSize-number. I set MaxSize to 3, but I could open 11 (and more...) concurrent DatabaseConnections (which wrote something to an existing table => I found the validation of this writing in the file /db/default.script)
Is there something wrong?
Thank you!
