Hi,
We need help as to why this is occurring when we try and runthis program in an AIX environment:
Connecting...

The version os AIX is 5.1 and MQSeries is 5.3 with CSD07.
The program is a very simple java program which just ries and connect to the local QMGR.
So... we have tried many ways of resolving this issue... but with no success.
Please advise.
Thanks.
Regards,
Nancy[/b] |

Nancy:
You have to set the environment variable on AIX
| Code: |
| LD_LIBRARY_PATH=/usr/mqm/java/lib |
That will get rid of the error. |

I beg to differ.
The environment variable on AIX is LIBPATH
The environment variable on Solaris is LD_LIBRARY_PATH
try adding as well:
| Code: |
| LIBPATH=$LIBPATH:/usr/mqm/java/lib/jdbc |
Enjoy  |

What do you mean the "AIX environment" as I also have LD_LIBRARY_PATH set to the following:
ampcst01:miagent:/home/miagent/bin>env LD_LIBRARY_PATH
/usr/mqm/java/lib
Please clarify.
Thanks. |

I also tried this and it didn't work:
ampcst01:miagent:/usr/mqm/java/lib>env LIBPATH
/usr/lpp/cmb/lib:/usr/java14_64/jre/lib:/usr/mqm/java/lib
ampcst01:miagent:/usr/mqm/java/lib>LIBPATH=$LIBPATH:/usr/mqm/java/lib/jdbc
ampcst01:miagent:/usr/mqm/java/lib>export LIBPATH
ampcst01:miagent:/usr/mqm/java/lib>env LIBPATH
/usr/lpp/cmb/lib:/usr/java14_64/jre/lib:/usr/mqm/java/lib:/usr/mqm/java/lib/jdbc
Still getting the same error.
Can you shed some more light on this matter? |

I checked on my AIX machine.
LD_LIBRARY_PATH is not part of my environment in AIX but LIBPATH is.
LD_LIBRARY_PATH is part of my environment on the Sun Solaris machine.

Thanks for the correction. LD_LIBRARY_PATH is for Solaris and Linux. LIBPATH is for AIX. |

OK... I did more testing...
The default java runtime on the AIX machine is java 1.3. I re-compiled my mqtest class using java 1.3 and it worked!
Now, I need to know why it doesn't work with java 1.4? Because I did not want to install java 1.4 on this AIX machine just in case it causes other problems to exiting applications running on it, I just copied the java 1.4 directories onto the AIX machine and include in my PATH the java 1.4. Hence, my mqtest can run with java 1.4. Resulting in the Unsatisfiedlink error with the libmqjbnd05.so file.
Does this mean that I have to install java 1.4 to get my program working? OR do you have any other suggestions? |

You should not require to do anything else use the JDK1.4 JRE. I take it you are executing the hava command <full path to java executable>/java
The libraries being run by the JRE in this case cannot pick up the libmqjbnd05.so. This means the path being searched by the MQ libraries does not contain the executable. I had the same problem running on NT and had to add the path to the library to the PATH variable. I do not know what the PATH is on an AIX box, I hope this give you a pointer to the problem.
The other thing you could try to do is re-compile your classes in 1.4 when running the 1.4 JRE. This should not really make any difference no harm in trying. |

This is really bizare. I compiled on NT in 1.4 being careful to use only 1.3 features(+ Lumberjack). Move the jar to AIX and it works fine.?
Are you sure you have everything you need in the CLASSPATH as well ?

I think so...
Here's the mqtest.class code:
import com.ibm.mq.*;
public class MQTest {
public static void main(String[] args) {
try {
System.out.println("Connecting...");
MQQueueManager queueManager = new MQQueueManager(null);
System.out.println("Connected.");
queueManager.close();
System.out.println("Closed connection.");
} catch (MQException ex) {
System.out.println("MQ Exception caught: " + ex.getMessage());
System.err.println(ex.getStackTrace());
} catch (Exception e) {
System.out.println("Exception caught: " + e.getMessage());
System.err.println(e.getStackTrace());
}
}
}
And this is the shell script I use to run the class above:
#!/bin/sh
CLASSPATH=$CLASSPATH:/usr/mqm/java/lib/com.ibm.mq.jar:/usr/mqm/java/lib/com.ibm.
mqbind.jar:/usr/mqm/java/lib/connector.jar
LIBPATH=$LIBPATH:/usr/mqm/java/lib
echo $CLASSPATH
echo $LIBPATH
java -cp $CLASSPATH MQTest
Please note I want to run it with jre 1.4. I don't know if t's because I haven't actually installed it onto the server that it won't allow me to access the mq libraries. I only copied the 1.4 directories onto this server and added in my PATH to use the 1.4 java instead of the default 1.3 (which is actually installed on the server).
Thank You for any suggestions you can give me. |

I believe you need to have /usr/java1.4.x/bin in your PATH variable.
My guess is that during execution you are mixing up the java versions.
Make sure your path sequence gives you the right jvm first.

Here's some more information:
ampcst01:miagent:/home/miagent/bin>which java
/home/miagent/java14_64/jre/bin/java
That is where I copied the jre 1.4 files. I have been using this. The result is still the same.
Any more suggestions? |

Yes
64 bit jvm has a few "features" you might want to read up on as far as MQ is concerned. I believe you can only use a Client Connection and your server has to be a specific version....
Back to the books.
