Need informix /sbin/init.d/informix startup/shutdown script

[Jack C. Mahaffey]

Anybody got an /sbin/init.d/informix startup/shutdown script for 11.0 to share? We're running informix 7.31 and the previous admin never created any rc scripts for startup/shutdown.

The current ~informix/.profile script includes prompts for whoever is logging onto the informix user account so doing a su - informix will not work. I want to leave the current ~informix/.profile alone.

I want to be sure that root can start the instance AND properly set the environment variables needed for starting/stopping the database. I figure I'll need to do 'su informix ...' commands but know they will fail if I do not have the correct environment variables and PATH's set prior to executing the commands.

Thanks in advance... Jack...

As we are an oracle-only shop, I do not have copy of my own but googling informix resources on the web turned this puppy. Hope it helps

Jack, see the attached scripts.

1. S995dbstart - /sbin/rc3.d

2. rcconfigscript - /etc/rc.config.d/dbstart

Jack, I'll try again here, by inserting the shells:

shell 1:
#file /etc/rc.config.d/dbstartdb ------------------------------------

export INFORMIXDIR=/informix
export INFORMIXSERVER=FOOBARk
export ONCONFIG=onconfig.FOOBAR
export IFMX_HPKAIO_NUM_REQ=5000
export KAIOON=1

# end file /etc/rc.config.d/dbstartdb


shell 2:
# file /sbin/rc3.d/S995dbstart -----------------------------------------

#!/bin/sh
set -x
#
# This script is to be used to startup and shutdown the Informix Server
# Optimized for HP/UX
#
# Installation instructions
#
# Copy this script to /sbin/init.d
# Link it to a start and a stop file in each of the rc?.d directory
# appropriate for the run level for which you wish the engine to be started, e
g:
#
# $ ln -s /sbin/init.d/informix /sbin/rc3.d/S900informix
# $ ln -s /sbin/init.d/informix /sbin/rc0.d/K500informix

Hi,

I'm no Informix admin,
but we have many Informix clusters running.
When I look at our init scripts I have to conclude that starting and stopping an Informix instance is astonishingly simple.
So you can easily create your own script from a copy of /sbin/init.d/template

All it requires is the setting of three environment variables, and issuing one on* command.

In your script export the following:

INFORMIXDIR
this must point to the root dir of your informix instance.

INFORMIXSERVER
this holds the name of your informix instance

ONINIT=onconfig # most of the times
this is the name of your instance's config file

With these set in the environment of the starting process simply run

$INFORMIXDIR/bin/oninit -v
to start your instance

$INFORMIXDIR/bin/onmode -ky
to shut down your instance


Whenever I needed to get my hands dirty with some (surface scratching) DBMS stuff I always admired the elegance and closeness to the UNIX philosophy of Informix.
You can run the most aggregated and involved query or admin tasks from the Unix shell like you are used to from Unix system administration.
I've never seen such with our Oracle DBMSs.

Thanks all.... Very useful info. The best place on the web for HP help. :)
