Connection Reset error on Oracle Native connection pool with Spring

Question

Am using Oracle Native connection pooling with Spring using Thin jdbc driver and noticing the below error

Exception in thread "main" org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLRecoverableException: IO Error: Connection reset

Here is how the data source is configured in spring configuration file

<bean id="datasourceone" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close">
    <property name="connectionCachingEnabled" value="true" />
    <property name="URL">
        <value>jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS=(PROTOCOL=TCP)(HOST=xyz-01) (PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=xyz-02) (PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ABCD)))</value>
    </property>
    <property name="user">
        <value>XYZ</value>
    </property>
    <property name="password">
        <value>XXXX</value>
    </property>
    <property name="connectionCacheProperties">
        <value>
            MinLimit:1
            MaxLimit:5
            InitialLimit:1
            ConnectionWaitTimeout:120
            InactivityTimeout:180
            ValidateConnection:true
        </value>
    </property>
</bean>

Would highly recommend if anyone can provide any recommendations around the same? Would tuning the connection pool help? If yes, is there anything specific that needs to get tuned?

Was it helpful?

Solution

Try using a different connection pool implementation and check if you see the same error.

OTHER TIPS

Try this as the connection string:

jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xyz-01)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=xyz-02)(PORT=1521))(LOAD_BALANCE=on))(CONNECT_DATA=(SERVICE_NAME=ABCD)))

and test again.
