Re: How Often Do You Reboot?
We have a substantial amount of Solaris and AIX servers. Whether it be test, QA or production, we almost never reboot. We have been running like this for years and it has caused us no problems.

Re: How Often Do You Reboot?
Title: Message We try to schedule reboot of servers every 4 weeks for a number of reasons. The main reason is to check that the machine will restart. Our Sysadmin's view is that you don't want some piece of equipment (hardware) or software that is critical to a restart but not normal operations to have failed 6 months ago and when you do finally reboot after applying maintenance the box fails and everybody points at the maintenance you've just applied. It's also easier to get downtime for maintenance if there's a regular reboot schedule as you can apply maintenance just before and let the regular reboot take effect. It will also clear out memory leaks, but this is not normally a problem with MQ (CSD03 for MQ5.3 permitting...)

Re: How Often Do You Reboot?
We like to try and reboot our servers on a fairly regular basis mainly to maximise clearing of dirty bits of memory that somehow always seem to hang around even if applications are closed cleanly. Most of our servers would get booted weekly (at weekends outside of normal business hours for us).

Re: How Often Do You Reboot?
It depends. The Solaris machines that we use to host client connections only get rebooted when the Unix admins need to add new hardware. The three of them have been up over 300 days now. We do recycle the queue managers on weekends, though. The Solaris application servers, on the other hand, get rebooted every night. This is because our applications required it in the distant past, and now we have some things that rely on it. But by the end of the year we should be in a position to keep the application boxes up all week, at least. But that makes me nervous. MQSeries has had leaks in shared memory usage at various CSD levels. We could get away with it because a reboot washed away all sins. But in June we were at record transaction levels, and we had a couple MQ outages when we exhausted our shared memory. So we went to CSD6 a couple of weeks ago, which seems to have stabilized things. But I won't really know until later this year. FWIW, the applications on this machine are nearly all Perl, and there are probably some that don't cleanly disconnect before they terminate. This caused a problem when we went to CSD3 a year ago or so (the queue manager would crash after a few hours), and we were forced to back CSD3 off and run on CSD1. But there was apparently a slower memory leak even at CSD1, as we saw in June. So I'm nervous about what I'll see when the app servers stay up around the clock.

Re: How Often Do You Reboot?
Rebecca - In our case we only reboot non OS390 servers when they lock up. This is not an MQSeries issue but a Windows or application issue. I have some Win2000 servers that have ONLY MQSeries on them and they have been up for one year yesterday. Your post reminded me to look at them and everything is just fine. The OS390 QMGRS are only taken down for maintenance or IPL and this is not often.

Re: How Often Do You Reboot?
Rebecca: In most cases you shouldn't have to reboot your systems, unless of course you are talking about Microsoft NT/2000/XP ;-) It was a significant issue with WMQ 5.1 that rebooting the box resolved some problems, but I believe in 5.2 and 5.3 those issues have been resolved. I have worked in several sites were they did not reboot their boxes for months, while other non-critical boxes was "at will". Development boxes can be rebooted as often as you choose, while production boxes should only be rebooted for maintanence purposes.
