#   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, eg:
#   
#   $ ln -s /sbin/init.d/informix /sbin/rc3.d/S900informix
#   $ ln -s /sbin/init.d/informix /sbin/rc2.d/K020informix

# Note: You can set the Informix environment several ways.
#   You can hardcode it here - or else you can set it using a file.
#   If you hardcode it here, it would look something like this...
#
#export INFORMIXDIR=/opt/informix
#export INFORMIXSERVER=myserver_shm
#export ONCONFIG=onconfig.myserver

# If you  set it using a file, it might look like this...
