How to Load/UnLoad messages from Websphere MQ Queues Using Qload & Unload Utility

(We need to download IBM MQ support pack named “MO03” to perform the below task)

Step 1: Let us assume we have a QMGR named QM1 & 2 queues named LQ1 and LQ2

Step 2:  Backup messages from a Queue to a file:

Command: qload –m QM1 –i LQ1 –f c:\bkpmsg

Step 3: import messages from a file to the queue:

Command: qload –m QM1 –o LQ1 –f c:\bkpmsg

Step 4: Copying messages from a queue to another queue:

Command: qload –m QM1 –i LQ1 –o LQ2

Step 5: Copying certain number of messages from a queue to another queue:

(e.g) we need to copy first 20 messages from a LQ1 to LQ2

Command: qload –m QM1 –i LQ1 –o LQ2 –r#20

“-r” Parameter:

x  =  Process x messages only

x..y  =  Process messages between x and y

X#y  =  Process messages from x to y count

#y  =  Process first y count of messages (just like in e.g)

Step 6: Move entire message from a queue to another queue:

Command: qload –m QM1 –i LQ1 –o LQ2
