Here is the command line I am using:
| Code: |
| java -classpath .:/usr/mqm/java/lib:/usr/mqm/java/lib/com.ibm.mq.jar:/usr/mqm/java/lib/connector.jar:/usr/mqm/java/lib/jta.jar:/usr/mqm/java/lib/fscontext.jar:/usr/mqm/java/lib/providerutil.jar -Djava.library.path=/usr/mqm/lib:/usr/mqm/java/lib mq_connector testqm |
Here is the class code:
| Code: |
import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQQueueManager;
import com.ibm.mq.MQQueue;
import com.ibm.mq.MQC;
import com.ibm.mq.MQException;
public class mq_connector
{
public static void main ( String[] args )
{
String qmName = args[ 0 ];
try
{
MQEnvironment.properties.put( MQC.HOST_NAME_PROPERTY, "" );
MQEnvironment.properties.put( MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES );
System.out.println( "connecting to qm " + qmName );
MQQueueManager tempQm = new MQQueueManager( qmName );
tempQm.disconnect();
}
catch( MQException mq_e )
{
System.out.println( "MQErrorCodes( " + mq_e.completionCode + ", " + mq_e.reasonCode + " )" );
mq_e.printStackTrace();
mq_e.getLinkedException().printStackTrace();
}
catch( Throwable t )
{
t.printStackTrace();
}
}
}
|
And here is the errir I am getting:
| Code: |
MQJE001: Completion Code 2, Reason 2059
MQErrorCodes( 2, 2059 )
com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2059

My initial guess is that you are suffering from segment 8 problems. Did you get an FDC file in /var/mqm/errors with a Probe Id of XY341019? If so, I'd suggest doing a search on the site for IPCCBaseAddress. You'll find information on how to get around the error.
If you are suffering from segment 8, an even better solution would be to upgrade to WebSphere MQ 5.3 which uses AIX extended shared memory to get around the problem. |

Awesome ... you reminded me of a fix I had done a while back:
export LDR_CNTRL=MAXDATA=0x40000000
This made the above program work!
Thanks. |

| The fix you mentioned is one of the ways to get around segment 8 problems. |
