Are there 3rd party softwares for linux restarting scheduler?

Can you be clearer as to what you're looking for? What do you want to schedule? –  Bill Weiss Jul 14 '10 at 14:58
    
In a previous question, the OP wanted to know how to schedule a reboot. Perhaps this is related. –  Dennis Williamson Jul 15 '10 at 1:11

Scheduled restarts of servers aren't usually a good idea, unless you're closely monitoring it to be sure it comes back up.

Your best option would be to install a monitoring tool like Nagios, but this would require a significant invest of time to setup. If you edit in more details of what you're trying to accomplish perhaps we can come up with a better solution.

Restarting a service, monitoring a service (watchdog/heartbeat), or restarting the server? I thought the question was ambiguous there. –  Bart Silverstrim Jul 14 '10 at 14:08
    
@Bart, good point; I hadn't thought of that. Though I'm still thinking most services probably shouldn't be restarted without some monitoring for the service to come back up. –  Chris S Jul 14 '10 at 14:16

WTF? The scheduler is a core part of the kernel and cannot be managed independently from user-space. Do you mean crond/atd? Something else?

Why does it need to be restarted?

Assuming you have a valid reason for restarting crond, then use crond to schedule an atd job - or if its atd you want to bounce, restart it directly from crond. But I suspect the question you are asking has nothing to do with the problem you are trying to fix.

C.

edit:

And why do you think you need 3rd party software to implement this?
