Re: Get instance names from PIDS?

You can deduce the server number from the shared memory key number - for example, using a script like this: #!/bin/perl -w # # @(#)$Id: shmkeynum.pl,v 1.1 2008/07/03 00:18:57 jleffler Exp $ # # Convert IDS shared memory key to Informix server number # 0x52754803 ==> Server 31 # 0x52754802 ==> Server 31 # 0x52754801 ==> Server 31 # 0x52674805 ==> Server 17 # 0x52674804 ==> Server 17 # 0x52674803 ==> Server 17 sub implausible { my($hex) = @_; return 1 if (($hex & 0xFF00) != 0x4800); return 1 if (($hex & 0xFF000000) != 0x52000000 && ($hex & 0xFF000000) != 0x53000000); return 0; } foreach my $arg (@ARGV) { my ($hex) = hex($arg); my ($num) = (($hex & 0x01FF0000) >> 16) - 0x56; if (implausible($hex) || ($num < 0 || $num > 255)) { printf "Invalid $arg\\n"; } else { printf "%3d $arg\\n", $num; } } Example use: $ shmkeynum 52674805 52564800 53554800 17 52674805 0 52564800255 53554800 $ On Fri, Apr 22, 2011 at 06:21, Fernando Nunes <domusonline@gmail.com> wrote: > I usually have a config file with all the instances and a function to get > all the environments. > So if I had to do that I would go through the list, set every environment, > check if it was up and stop it. > > This is useful for a lot of other situations, so I usually wouldn't bother > in trying tricks that only solve one issue. > Regards. > > > On Thu, Apr 21, 2011 at 2:11 PM, Malc <malcrp@googlemail.com> wrote: > >> Here's one for you: >> HP-UX 11i, IDS9.5 >> Imagine I'm trying to find out which instances are up and running in >> an automated shutdown script,and I have no prior knowledge of the >> setup.
