Middleware Technologies: Clearing all messages from a queue through Shell Script

I have written a shell script to find out how many messages are struck in queue and purging/deleting messages from queue.

Download the following script and store it in a location such as /usr/local/bin.

Provide the file permissions and ownership for this script as you see fit. In this example, they are:

$ chmod 755 /usr/local/bin/clear-mq-messages.sh

$ chown mqm:mqm /usr/local/bin/clear-mq-messages.sh

$ ls -l /usr/local/bin/clear-mq-messages.sh

-rwxr-xr-x 1 mqm mqm 1296 Oct 30 14:34 clear-mq-messages.sh

#!/usr/bin/ksh

echo -e "\nPlease enter the \"queuemanager\" !!!"

read queuemanager

echo -e "\nPlease enter the \"input_queue\" !!!"

read inputqueue

struck_message=`echo "DISPLAY QL($inputqueue) CURDEPTH" | runmqsc $queuemanager | grep 'CURDEPTH(' | sed 's/.*CURDEPTH//' | tr -d '()'`

if [ $struck_message = "0" ]; then

echo -e "==============================================="

echo "now no messages in " $inputqueue

echo -e "==============================================="

echo -e "\n\nThank you!!! Bye!!!\n"

exit 0

else

echo -e "==============================================="

echo "the" $inputqueue "CURDEPTH count is" $struck_message

echo -e "==============================================="

echo -e "Would you really like to flush the $inputqueue? <y/N> "

read prompt

if [[ $prompt == "y" || $prompt == "Y" || $prompt == "yes" || $prompt == "Yes" ]]

then

echo -e "************************************************"

echo "clear qlocal($inputqueue)" | runmqsc $queuemanager

echo -e "************************************************"

struck_message2=`echo "DISPLAY QL($inputqueue) CURDEPTH" | runmqsc $queuemanager | grep 'CURDEPTH(' | sed 's/.*CURDEPTH//' | tr -d '()'`

echo "Now the CURDEPTH count is" $struck_message2

echo -e "************************************************"

else

echo -e "\n\nThank you!!! Bye!!!\n\n"

exit 0

Let see how this script will work

while script executing time this script will ask QueueManager name & queue name.

Let see CURDEPTH count only....

If CURDEPTH count is zero, the script will work as below

I hope this information is helpful to you
