reboot without running startup script 1

[hok1man]

Hi guys,

just wondering which files do we need to be commented out so once we reboot, the startup script is not running?

Thanks guys,

I presume you mean one specific startup script? If so, go to the relevant runlevel directory, say /etc/rc3.d, and rename the script from SNNxxxxx[b/] to sNNxxxxx (i.e. change the S to lowercase). That will prevent it from being run.

If you disable all startup scripts you probably will not end up with a usable system.

Which *nix? Anni's solution will be fine except that some varieties (AIX for example) use things like /etc/inittab to read on startup - commenting the entry out of that file will stop the script from running in that event. I believe the variations of Linux also have differing ways of specifying startup scripts.

I want to be good, is that not enough?

My personal answer is to edit the startup script to look for a 'no_run' flag. e.g.

#!/bin/ksh
#Abort if no run flag set
[[ -f /tmp/no_run ]] && exit

We have a system which under normal circumstances starts ~50 Oracle databases plus lots of other things. When we're doing maintenance on it we may need a quick reboot and this saves lots of trouble

Thanks guys,

I believe there's some one configuration files/way that we can commented out...
like in windows there is like msconfig.sys

what about in linux/unix solaris 10?
do they just dump reading the list of files in directory?

 

[Annihilannic]

Yes, that's basically what they do. During the startup phase the scripts that match S* are executed in the same order as they would appear in ls.

Also, since you are using Solaris 10, many services are controlled by the SMF ("Service Management Framework" I think). You would turn those on and off using the svcadm enable and svcadm disable commands.

[hok1man]

does the svcadm work if we want to disable some scripts only?

can you pls show me the sample of this?

Thanks man,
