    Connection pool problem jboss 5.1 + hibernate oracle 11.2.3.0 DB,Hibernate 3.3.2.GA

    shirish maurya Newbie

      issue with connection management for jboss 5.1 + hibernate, my hibrenate uses jndi name define for connection pooling,

       

      below is the hibernate configuration

      03:29:45,068 INFO [SettingsFactory] Automatic flush during beforeCompletion(): disabled

      03:29:45,068 INFO [SettingsFactory] Automatic session close at end of transaction: disabled

      i have also made a connection release mode to on close and track transation track statement  but no where it helps

       

      ds file config

       

      min-pool-size>8</min-pool-size>

      <max-pool-size>100</max-pool-size>

      <blocking-timeout-millis>50000</blocking-timeout-millis>

      <use-strict-min>true</use-strict-min>

      <track-statements>true</track-statements>

      <metadata>

      <type-mapping>Oracle11g</type-mapping>

      </metadata>

      </local-tx-datasource>

      </datasources>

       

       

      after certain duration of time say 30 mins the connection problem arises, this happens as i increase the concuurent users. the connection are getting closed out from the code.

      also i see a lot of inactive session at DB end increase duration the test period.
