HP UX Reboot timing

[dileep_1]

For a very specific requirement of ours, we need to know if there is any timeframe after which the unix server has to be rebooted. OR, are there any software issues in the HP UX which demands the server to be rebooted periodically. If so, what is the time frame and how do we identify the situation.

Does any Unix (or a clone, or linux) specify that the server has to be rebooted after this time period??
Any specific info about HP UX version 8 is also welcome.

Rgds,

No, is the short and simple answer.
We have had systems up without reboot sfor up to 5 years!

As to version 8 of HP-UX?
Went out of support many years ago.

Hi Dileep,

I concur with Melvin, although we don't have systems running for that long. Maybe because, as a contractor, I never stay that long in a company ;-)

If you apply kernel or network patches, you'll have to reboot thereafter. For that reason, there's no need to plan any other reboot for your servers.

If you still have systems running HP-UX 8, I think that you should consider upgrading because they are out of support for ages...

Best regards,

Dan

I don't think there is definite requirements for rebooting a Unix server periodically, but, it is GOOD PRACTICE for doing so, reasons are

1. through reboot you can re-claim any leaked memory caused by ill-behaved processes.

2. through reboot you can get rid of any zombie (defunc'ed) processes.

3. you'll know if any system changes would caused your server being not able to reboot.

Yes, Unix stability is famous, I'm not any expert but I also got servers that could live without rebooting (provide that I don't make any drastic system changes).
