IBM MQSeries Gateway

I would like to connect to IBM MQSeries v.5.3
from an Oracle 9.2.
According to Metalink and Oracle documentation,
I could use PG4MQ
(Oracle Procedural Gateway) or
Messaging Gateway using AQ.
They have different architecture
and different configuration.
Which one is better ?
During the Oracle installation I
have only the PG4MQ option,
so how I could use Oracle Procedural Gateway
Thanks

Dear Yang!
I have the same problem considering the two possibilities to connect ibm with oracle...
Did you get some useful information or do you have some experience now? If yes could you please update the post!
Thanks

Sender JMS adapter configuration for IBM MQSeries

Dear All,
i am doing a IBM MQSeries 5.2.x Message ->sender JMS adapter -> XI server -> receiver RFC adapter -> R/3.
i have deployed the JMS adapter with the required jar files of IBM MQSeries 5.2.x in XI server.
in Sender JMS adapter configuration for IBM MQSeries 5.2.x, i have put following data:
1. Transport Protocol: Websphere MQ - is it okay?
in JMS provider settings:
2. in channel name - what should be there?
3. Transport Network protocol should be TCP/IP or WebsphereMQ - how to decide this thing.
4. JMS Complaint - whether WebsphereMQ or JMS API.
in JMS Settings:
5. JMS Queue user - is this IBM MQSeries 5.2.x Queue User or someother user?
6. JMS Message Selector - what data to take here.
So if anybody has connected IBM MQSeries 5.2.x to XI via JMS adapter, please answer my above queries.
Regards,
Rajeev Gupta

Hi Swaroop,
you can send me those documents at my gmail-id : [email protected]
Hi All,
one more question - to connect XI server to IBM MQSeries via JMS adapter in ID, do we need to have a MQSeries Client installed on XI server - or - just by configuring JMS adapter, we can send messages from IBM MQSeries to XI server without any MQSeries client on XI server?
Why Channel name is required in JMS configuration data?
Thanks,
Rajeev Gupta

Remote queue in XI server for IBM MQSeries

Dear All,
my scenario is IBM MQSeries -> message via sender JMS adapter -> XI -> receiver RFC adapter -> R/3.
now for IBM MQSeries to send a message to XI via a transmission queue in MQSeries - it needs a remote queue name and queue manager name in XI server.
So now where can i find these information regarding remote queue name and queue manager name in XI server. I currently do not know whether in XI server, currently is there any remote queue or not? So how to find this information. If we do not have remote queue manager in XI currently, then how to install a remote queue name and queue manager in XI server.
It is slightly urgent. So i request you all to please reply quickly.
Thanks and Regards,
Rajeev Gupta

Dear Sebastin,
Thanks for your inputs.
I have to connect to MQSeries 5.2.1 to XI server.
am getting the below error in Communicatin Channel Monitoring for my sender JMS adapter:
Error during channel initialization; exception trace: javax.jms.JMSException: MQJMS2005: failed to create MQQueueManager for '<IP_ADRESS>:<MQ_QUEUE_MANAGER>'

at com.ibm.mq.MQClientManagedConnectionFactoryJ11._createManagedConnection(MQClientManagedConnectionFactoryJ11.java:228)
i have written '<IP_ADRESS>:<MQ_QUEUE_MANAGER>' just to hide the data - i am getting <IP_ADRESS> as IP Adress i gave in JMS adapter and <MQ_QUEUE_MANAGER> as Queue Manager i gave in JMS adapter.
i am using the correct IP and 1414 port of MQSeries server. I have used a MQQueueManager defined in MQSeries. i have deployed JMS adapter properly in XI server.
So can anybody suggest what could be the possible reason of this error and how to rectify it. It is slightly urgent.
One more question - should the queue manager in MQSeries server be a local or remote queue manager..........i was not able to create a remote queue manager in MQSeries 5.2.1 as by default it is creating a local queue manager.......
Thanks and Regards,
Rajeev Gupta

Newbie : Problem starting OPG for IBM MQseries: TNS-00530, Error Code 2

Hi All
First of all, if this is the wrong place to post this question, I apologize.
I have installed a new installation of Oracle 9.2.0.1 and at a separate home location the OPG for IBM MQSeries for 9.2.0.1 off the same bits.
The configuration said that the default SID of PG4MQS92 would be setup since I was using a local MQ queue manager but I didnt see any entries in the listener.ora or the tnsames.ora so added the following.
listener.ora
(SID_DESC =
(SID_NAME = pg4mqs92)
(ORACLE_HOME = C:\Software\oracle\pg4mqs92)
(PROGRAM = pg4mqs92)
tnsnames.ora
ORACLE_QM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = testmachine)(PORT = 1521))
(CONNECT_DATA =
(SID = pg4mqs92)
(HS=OK)
When I ran tnsping on ORACLE_QM it was resolved. But when I start the putsample.sql program after importing all the required packages using the pgmdeploy9.sql script I get the following output.
DECLARE
ERROR at line 1:
ORA-04052: error occurred when looking up remote object

ORA-28545: error diagnosed by Net8 when connecting to an agent
NCRO: Failed to make RSLV connection
ORA-02063: preceding 2 lines from PG4MQ
In the listener.log I see the following error
07-DEC-2005 07:34:19 * (CONNECT_DATA=(SID=pg4mqs92)) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.100)(PORT=1271)) * establish * pg4mqs92 * 12500

TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 2: No such file or directory
I noticed that during the install a boot file for the pgm4mqs92 SID was not found anywhere. Is it maintained in the registry, if so where ?
If the boot file is missing is there a sample I can use and where do I need to put it ?
Am running on Windows XP Professional.
Have been stuck with this a while and cannot find any information on this, so any help would be appreciated.
Thanks

JMS versus IBM MQSeries

1. What is the difference between JMS and IBM MQSeries ?
2. If JMS is all about APIs to interact with Message Oriented Middleware (MOM) that IBM MQSeries supports, why not use a simple JAVA program that would import com.ibm. * packages instead of JMS APIs ? What is the benefit we derive from using JMS ?

I think what you are saying is JMS is the preferred
way to communicate with MOM (i.e. MQ) as it is
standard and not vendor dependant. My concern is
this:
If we write a stand alone program to send/retrieve
meessage from MQ then how do we create
ConnectionFactory and connection? Personally I prefer to use Dependency Injection using a library like Spring to configure things like JMS connection factories, JDBC DataSources etc.
http://www.springframework.org/
though the more typical (and some would say official) way of doing it is to use JNDI in your application. So create a JNDI context and pull the JMS ConnectionFactory and destinations out of JNDI.
e.g. like this
http://svn.activemq.org/trunk/activemq/modules/core/src/test/org/activemq/demo/SimpleProducer.java?rev=1&view=auto
Then you need to refer to your JMS provider's documentation on how to configure a JNDI context. Typically its a case of adding a jndi.properties file to the classpath configured to your provider's JNDI provider.
Don't we need MQ
classes to create these objects.Yes, you need the classes from your JMS provider to create connections & sessions. (Its not like EJB remoting where you can create client side proxies from the EJB interfaces).

Message Bus to IBM MQSeries bridging?

Hi,
I need to connect from Azure to IBM MQ series queues. I have found some documentation about a MSMQ->MQSeries bridge which is part of some Hosting software which doesn't exist anymore.
In pratical terms, how to approach this from Azure? What steps to take?

hi Werner,
There is a document about message connection between IBM queues and azure service bus. You could refer to

Why use IBM MQSeries when Weblogic already provides JMS?

i kind of understand that MQSeries works the same as JMS provided by WebLogic, so there is not much a point to use MQSeries, but why do companies still use MQSeries when JMS is already provided by WebLogic?
what are the advantages of using MQSeries over WebLogic provided JMS?

I don't think there's necessarily much reason to adopt MQ, unless perhaps you have very specific messaging extensions or capability requirements. There are performance, manageability, and scalability benefits in using WebLogic JMS, especially when it is integrated with WebLogic applications. There also happen to be benefits in using the Oracle DB's built in messaging (AQ JMS).
There are tens of thousands (if not 100s of thousands) of production WL JMS deployments out in the wild - some of which are "mission critical" and quite large, and some of which have been running for 10+ years. It's not unlikely that you generate multiple WL JMS transactions per day, just going about your daily life (phone, bank, credit card, financials, etc.).
Of course your mileage may vary - and keep in mind that you're posting to WebLogic JMS forum. :-)

Using MDB with IBM MQSeries

          Hi All,
          I want to use MDB with MQSeries as Messaging medium.
          My Weblogic App. server version is 6.0
          I want MDB to get invoked whenever any message comes in MQSeries queue.
          I think 8.1 version provides a option to add external JMS server.
          Is it possible in 6.0 version?
          Please let me know ASAP.
          Waiting for reply!
          Thanks,

Hi Prasanna,
          The best resource is the white-paper, which mentions MQ directly:
          http://dev2dev.bea.com/resourcelibrary/whitepapers/jmsproviders.jsp
          But it does not take into account the following 8.1 feature:

Sending a message to MQSeries using with international characters

Hello
I managed to setup oracle messaging gateway to IBM MQSeries. While sending and receiving English message is Fine, sending international characters (8bit Arabic) is received as ??????. I know how to fix this issues when using normal oracle tools. But for the MGW, i cannot find in the documentation where to find the National Language support setting NLS_LANG

RESOLVED
It had nothing to do gateway setting. Actually, it was my mistake. The client environment setting was not correct.
Once corrected, all went fine

when I run dbms_mgwadm.startup, I get ORA-32830: result code -3 returned by Messaging Gateway agent as the last_error_msg when I query mgw_gateway. There is no log generated in $ORACLE_HOME\mgw\log. If I rerun dbms_mgwadm.startup, the agent is reachable - what could be wrong ?

Hi,
-3...An error occurred creating the MGW log file. Verify that the log directory is writeable. The default location is <ORACLE_HOME>/mgw/log.
In documentations is described the following on the link:
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96587/qfaqs.htm
What if MGW_GATEWAY view shows LAST_ERROR_MSG of "ORA-32830: result code <value> returned by Messaging Gateway agent?"
The result code may be one of the following:
-1...An error occurred starting the Java Virtual Machine (JVM). Check the MGW log file for an entry that contains one of the following lines.
Can't create Java VM Verify that the Java version you are using is correct. Verify that your operating system version and patch level are sufficient for the JDK version. Verify that you are using a reasonable value for the JVM heap size. The heap size is specified by the max_memory parameter of dbms_mgwadm.alter_agent.
Can't find class oracle.mgw.engine.Agent Verify that the CLASSPATH set in mgw.ora contains mgw.jar. For example:
set CLASSPATH=<ORACLE_HOME>/mgw/classes/mgw.jar
-2...An error occurred reading mgw.ora. Verify that the file is readable.
-3...An error occurred creating the MGW log file. Verify that the log directory is writeable. The default location is <ORACLE_HOME>/mgw/log.
-100...The MGW agent JVM encountered a runtime exception or error on startup.
-101...The MGW agent shut down due to a fatal error. Check the MGW log file.
