UNIX for Dummies Questions & Answers

hi guys

I have a service that depends on some shares (NFS shares ) that need to be mounted before before the service start so the service-app finds the NFS shares and starts correctly...

I am confused here this is what I found but I am not sure what to do in order to change it

BTW is Suse 11

this is rc3.d and rc5.d

Code:

lrwxrwxrwx 1 root root 22 Mar 13 16:03 K01tsminst1_dsmserv.rc -> ../tsminst1_dsmserv.rc
lrwxrwxrwx 1 root root 22 Mar 13 16:03 S01tsminst1_dsmserv.rc -> ../tsminst1_dsmserv.rc

lrwxrwxrwx 1 root root  6 Mar  1 14:39 K04nfs -> ../nfs
lrwxrwxrwx 1 root root  6 Mar  1 14:42 S05nfs -> ../nfs

any idea?

Edit
I found something K - Kill - S - Start for the services
so in this case I just need to start tsm(S01) after nfs(S05) since it looks like the shutdown process is OK TSM is shutdown first (K01) and NFS after (K04)

so in my case I need change just the start order so NFS start first than TSM

thanks a lot

I don't know what TSM is on your system or whether other items in startup depend on it.
Subject to thorough checking, the general answer is to rename the link S01tsminst1_dmserv.rc to something numerically higher than any of it's prerequisites.
e.g. S90tsminst1_dsmserv.rc .
The rc Start (S) scripts are executed in numeric order of the number after the "S".
On a unix system this is described at length in man rc. I don't know about your Linux system or whether it can deal with numbers above 99. On a unix system I'd spread the startup scripts across a wider range of numbers to fit in with system scripts.

I have some reservation about starting anything dependent on NFS in the main system startup because if the NFS mount is not available for some reason (and you do not have code to deal with this situation) you could end up with a system which hangs on startup.

thanks a lot I was about to post it

I just changed to S06 ad worked OK....

S01tsminst1_dsmserv.rc ----> S06tsminst1_dsmserv.rc so in that way it starts after S05nfs

thanks a lot methyl it was easy as cake
