Hi All,
I got an error while trying to connect to the QueueManager using Java interface in bindings mode. When I searched for that error on IBM site, I found the exact same error information in the FAQ. I am pasting that FAQ here.
The only different between this and my problem is I am running on HP Unix and I have JDK 1.4 installed.
FAQ
Question:
Running the MQ Java product on my Compaq (DEC) OVMS system, why do I get the error: Exception in thread main java.lang.UnsatisfiedLinkError: no mqjbnd01 in java.library.path?
A: The most likely cause is having the wrong Java JDK version installed on your system. Currently, version 1.1.8 is the only supported version.
In running MQ Java bindings mode with Compaq JDK 1.2.2 and 1.3, unlike other platforms, the various JDKs supply a shareable image (Java JAVA_SHR.EXE) which is not compatible with the MQ shareable image (MQJBND01) linked with JDK 1.1.8. Use JDK 1.1.8 for bindings mode. It may be possible to use JDK 1.3 for client mode connections yet this has not been tested.
So My questions is,
Does this mean I cannot run a Java application to connect to the Qmanager on HpUnix if I have a javaversion 1.4??
Please correct/clarify my doubt.
thanks
keka

I may be wrong but if you are trying to work with mqjbnd01 it probably means that you have an old version of the MQ Series classes for Java.
You should download and install a newer version of these classes (in support pac MA88).
(If you are working with WMQ 5.3 the MQ Series classes for java are part of the standard package).

I just took a quick look at MA88. It states the following:
Supported Java Development Kit versions:
AIX - IBM Software Development Kit (SDK) 1.3.1
HP-UX 10-20 - HP-UX SDK 1.1.8
HP-UX 11 - HP-UX SDK 1.3.1
iSeries - IBM SDK 1.2.2 and 1.3.0
Linux - IBM SDK 1.3.1
OS/390 or z/OS - IBM SDK 1.3.1
Solaris - Sun SDK 1.3.1
Windows 95, 98, NT, 2000 - IBM SDK 1.3.0
Here is a direct link:

| If you are truly running MQSeries 5.1, then it may or may not work. But it is definitely not supported. You need to move your MQ forward. |

| We have similar problem on AIX 4.3 MQ5.2 with MA88 and JDK 1.3.1 I believe. Binding mode wouldn't work. Call to IBM, response was "It's a bug" with a convoluted work around. Call IBM and if it is the same bug then they will send you the same convoluted work around. We are using client connections as a bandaid until we can decifer and possibly implement IBM's bandaid. This may be a UNIX thing as bindings work fine in the Windows world with MA88 and current JDK. |

I would guess that the bug that you are mentioning is the 'segment 8' problem. Personally, I would have called it a limitation. Regardless, with WebSphere MQ 5.3, you can get around this by using extended shared memory. You'll basically run with EXTSHM=ON set and life will be good.
This problem only showed up on AIX. |

I need to use the EXTSHM=ON; however, I don't understand if this environment variable needs to be set for every user that executes an MQ application, or just the user that starts the queue manager.
The deal is that we have MANY different users that connect programs to queue managers that only start/run under mqm. It would be kind of a pain to go out and set the environment variable for every user's profile.
Alternatively, can we just set it at the system level somehow?
Please let me know what you think if you got a minute...
