Opening queues is very cpu and time intensive compared to puts and gets. Yes, you can open the queue for the day.
-----Original Message----- From: Dean Montevago [mailto:[EMAIL PROTECTED] Sent: Monday, September 20, 2004 2:43 PM To: [EMAIL PROTECTED] Subject: Keeping MQ Queues Open Hi, We have a application that sends data from z/OS to AIX. All the MQ work on z/OS is done from a program that is linked to by a number of CICS programs. There are 5 channels/queues going down to the AIX. The data is spread across the channels/queues via a key in the message. What I'd like to know is, can the queues be opened once and left open for the entire processing day ? and closed at EOD. Now, when the transaction ends the objects are closed. I was curious if repeated opens are costly ? and looking to avoid that. The application folks want to keep the MQ program as simle as possible. We do 7-10 million messages a day, I know there are places that do many times more than this and I'm curious how they handle it. Any input would be greatly appreciated.
