XA error: XAER_RMFAIL : Resource manager is unavailable

@10

Hi,
We are getting the below error message in WebLogic 8.1SP6 server logs when sending an order from WLS 10.3.3 to WLS 8.1SP6. These two are integrated using a Message bridge.

<JDBCConnectionPool CapacityIncrement="2"
        ConnectionReserveTimeoutSeconds="60"
        DriverName="oracle.jdbc.xa.client.OracleXADataSource"
        HighestNumWaiters="1000"
        InactiveConnectionTimeoutSeconds="14400"
        InitSQL="SQL SET ROLE WOTSTWTWWOO identified by AYLDTT"
        InitialCapacity="10" MaxCapacity="100" Name="MSLVwliPool"
        PasswordEncrypted="{3DES}jv7hYflFsH0=" Properties="user=app_int"
        ShrinkFrequencySeconds="300" Targets="m6cluster"
        TestConnectionsOnCreate="true"
        TestTableName="SQL SELECT 1 FROM DUAL" URL="jdbc:oracle:thin:@10.113.244.145:23321:prdm6db"/>

Would it make any difference if the below two parameters are enabled?

Test Reserved Connections
Keep XA Connection Till Transaction Complete

Thanks,
