Hibernate version: 3.0
We are using hibernate 3.0, spring 2.0.6 and trying to connect to an Oracle 10G database.
Following are the connections.xml file details.
Code:
<bean id="coreDataSource"
class="com.mchange.v2.c3p0.ComboPooledDataSource"
p:driverClass="${core.jdbc.driver}"
p:jdbcUrl="${core.jdbc.url}"
p:user="${core.jdbc.user}"
p:acquireIncrement="10"
p:acquireRetryAttempts="0"
p:initialPoolSize="5"
p:maxIdleTime="3600"
p:maxIdleTimeExcessConnections="300"
p:minPoolSize="5"
p:maxPoolSize="200">
<property name="password">
<bean class="com.docfinity.util.encryption.SpringStringDecrypter"
p:decryptFlag="${core.jdbc.decryptPasswordFlag}"
p:encryptedString="${core.jdbc.password}" />
</property>
</bean>
The connection properties associated with it.
Code:
core.jdbc.driver=oracle.jdbc.driver.OracleDriver
core.jdbc.url=jdbc:oracle:thin:@spider-man:1521:testplan
core.jdbc.user=docfinity10Dev
core.jdbc.password=XXXX
core.sql.dialect=org.hibernate.dialect.Oracle9iDialect
core.jdbc.type=jdbc:oracle
core.jdbc.server=spider-man
core.jdbc.name=testplan
core.jdbc.decryptPasswordFlag=false
core.jdbc.maxRows=0
We keep getting the following exceptions while our code is running.
Code:

Has anyone ever faced similar issue with Oracle? Do we need to tune oracle server properties? If so which ones?
