I want to introduce a delay of some secs in my compute node. i.e. I want to put a message in a Queue after a time delay. Is there a way to do this in ESQL code?
I'm using only MQSI here and ESQL coding. |

This is not a good idea. May I know why do you need to do this in MQSI?

It is very bad!!! idea - you can use miltiple instances of message flow, but how many messages you have at delay time? Becouse your flow will stuck at this period...
If you just want to stop(delay) a processing - try folowing scenario:
1. All messages arive on Q1
2. Message Flow T1 has input node Q1 and output node Q2
3. your regular processing listen to Q2
If you have WMQI 2.1, you can control flow T1 (stop-start).
Otherwise use external application for delay.

You still need some external application (APP) to manage your timeouts.
The concept is using switch - GET INHIBITED/ALLOWED.
1. Create flow T1 as I described in previous message.
2. Q1 is disable (GET INHIBITED) by default
2. APP will sent message which set GET ALLOWED on Q1
3. later (after 10 sec, when Q1 is empty etc) APP will sent message which set GET INHIBITED on Q1.
How APP will switch the parameter?
1. It can sent PCF command to SYSTEM.ADMIN.COMMAND.QUEUE
2. It can sent XML message to MQSI flow (T2), which convert it to PCF command and then transfer it to SYSTEM.ADMIN.COMMAND.QUEUE.
3. If you are not familiar with PCF - visit http://www.kolban.com/mq/ where you can dowload MQDisable node ( http://www.kolban.com/mq/wmqi/wmqi_mqdisable_node.htm ).
I guess it use same concept. Put this node in flow T2.
May be scenario when APP transfers messages from Q1 to Q2 will be more useful in your case...

I am sure you can create it by yourself 
BTW - you need 2 flows: 1 to disable Q with checked node and 1 to open the Q with unchecked node.
Good luck!!!
