Eric Ferrer commented on DBCP-196:
----------------------------------
OJB is configured to use DBCP as its pool, the params passed are as follows
<jdbc-connection-descriptor jcd-alias="APPLICATION"
default-connection="true" platform="MsSQLServer" jdbc-level="4.0"
driver="net.sourceforge.jtds.jdbc.Driver"
dbalias="//myDba:8989/myDBA;SelectMethod=cursor"
username="myDBA" password="myDBA"
eager-release="false" batch-mode="false" protocol="jdbc"
subprotocol="jtds:sqlserver"
useAutoCommit="1" ignoreAutoCommitExceptions="false">
<connection-pool maxActive="255" validationQuery="SELECT 1" />
</jdbc-connection-descriptor>
> Unexpected error with DBCP and OJB where OJB was unable to get a connection.
> The root cause appears to be a org.apache.commons.dbcp.SQLNestedException:
> Cannot get a connection, pool exhausted, cause: null
