Hi, Everybody,
I dealing with WebSphere MQ 6 - ORACLE 10g connection.
I have to PUT / GET messages to / from a remote QM via ORACLE Messaging Gateway.
The Ora scripts are the following:
'
DECLARE
v_options sys.mgw_properties;
v_prop sys.mgw_mqseries_properties;
BEGIN
v_prop := sys.mgw_mqseries_properties.construct();
v_prop.max_connections := 1;
v_prop.interface_type := Dbms_Mgwadm.JMS_QUEUE_CONNECTION; --MQSERIES_BASE_JAVA_INTERFACE
v_prop.username := 'UserName';
v_prop.PASSWORD := 'Password';
v_prop.hostname := '192.168.0.77';
v_prop.port := 1417;
v_prop.channel := 'SYSTEM.DEF.SVRCON';
v_prop.queue_manager := 'QM_GENCS';
v_prop.outbound_log_queue := 'SYSTEM.JMS.D.SUBSCRIBER.QUEUE';
-- Specify a WebSphere MQ durable subscriber queue to be used with the
-- log topic.
-- v_options := sys.mgw_properties(
-- sys.mgw_property('MQ_JMSDurSubQueue', 'ORA_LOG'));
Dbms_Mgwadm.create_msgsystem_link(
linkname => 'mqjms', properties => v_prop, options => v_options );
END;
------------------------
BEGIN
Dbms_Mgwadm.register_foreign_queue(
NAME => 'testmq',
linkname => 'MQJMS',
provider_queue => 'ORA_IN',
domain => Dbms_Mgwadm.DOMAIN_QUEUE);
END;
------------------------
BEGIN
Dbms_Mgwadm.add_subscriber(
subscriber_id => 'sub_aq2mq',
propagation_type => Dbms_Mgwadm.outbound_propagation,
queue_name => 'ADMIN.QUEUE',
destination => 'TESTMQ@MQJMS');
END;
'
The error message in the oramgw*.log (Messaging Gateway log) is the following:
'
>>2007-10-03 17:29:18 MGW Engine 0 EXCEPTION main
java.lang.NoClassDefFoundError: com/ibm/mq/jms/MQConnectionFactory
at oracle.mgw.drivers.mq.jms.MQJmsLink.<init>(MQJmsLink.java:9
at oracle.mgw.drivers.mq.MQLinkParamsNFactory.createMsgLink(MQLinkParamsNFactory.java:339)
at oracle.mgw.engine.MsgLinkMgr.addLink(MsgLinkMgr.java:64)
at oracle.mgw.engine.Agent.initAgent(Agent.java:468)
at oracle.mgw.engine.Agent.start(Agent.java:132)
at oracle.mgw.engine.Agent.agentMain(Agent.java:698)
'
The 'v_prop.channel := 'SYSTEM.DEF.SVRCON';' is OK.? If NOK, which type of channel have to specify?
What is the trouble?
Thanks for the help!

The trouble maybe is that you don't have the MQ client installed on the Oracle machine, and have all the necessary MQ classes on the classpath.

Does the user starting the gateway / oracle have the jars needed on the classpath?

The Oracle database, Messaging Gateway and the Websphere queue manager are in the same host therefore there is not a MQ client in this machine. It is maybe a problem?

You'd still need the client installed if you're trying to establish a client connection.

Hi
I am not sure, whether IBM has come up with the fix pack for 2 Phase commit transactions with Oracle Database.
As there is an issue with MQ 6 at first...

Gayathri - I don't see how that would result in a noClassDefFoundError...

I have an MQ 6 Client on the host.
The question is that the Ora 10 MGW knows the WebSphere MQ V6 or only V5.3?

Sorry Jeff, thats only an information.
CLASSPATH haven't exported properly i believe in this part.
request you to check the proper jar files are present in the respective dir

Sure seems one to me. AFAIK the Oracle Messaging Gateway tries to establish a client connection to MQ...

Thanks for the advices!
I have succeeded in connection the Ora Msg and WS MQ via Srvr Conn channel and java SYSTEM queues.
