It is possible to install, configure and run a legacy Informix
Database on OpenServer 6.0.0 if you have Maintenance Pack 3 or
later installed.
This article describes the steps needed to install
Informix IDS 7.31 UC5 for OpenServer 5.0
but these steps can be adapted to install other Informix databases.
Installation of Informix IDS 7.3 can be broken into 3 phases:
1) Configuration of OpenServer 6.0.0 prior to installation of
the Informix Database
2) Installation of the Informix Database
3) Configuration of the Informix Database
4) Initializing the Informix Database
5) Testing access to your Informix Database
The steps for each phase are described below:
1) Configuration of OpenServer 6.0.0 prior to the
installation of the Informix Database.
Before you install the Informix database on your OpenServer
6.0.0 server you must:
- Install Maintenance Pack 3 or later onto your server. You
can download the latest Maintenance Pack for OpenServer 6.0.0
from:
http://www.sco.com/support/update/download/product.php?pfid=12&prid=20
- Log into the server as root
- Using the SCOadmin Account Manager, create a new group
called informix with an id greater than or equalt to 100
- Using the SCOadmin Account Manager, create a new user
called informix and make the group informix the login
group of the informix user
- Edit the root user account /.profile and add the following:
INFORMIXDIR=/u/informix
export INFORMIXDIR
PATH=$PATH:$INFORMIXDIR/bin
export PATH
ONCONFIG=onconfig.std
export ONCONFIG
INFORMIXSERVER=scodb1
export INFORMIXSERVER
- Edit the informix user account .profile (/u/informix/.profile)
and add:
INFORMIXDIR=/u/informix
export INFORMIXDIR
PATH=$PATH:$INFORMIXDIR/bin
export PATH
ONCONFIG=onconfig.std
export ONCONFIG
INFORMIXSERVER=scodb1
export INFORMIXSERVER
These environment variables tell the Informix installation
scripts and utilities:
- where Informix is to be installed (ie /u/informix)
- where to find Informix binaries (ie /u/informix/bin)
- what the name of the Informix configuration file will be
(ie onconfig)
- what the name of the database server will be (ie scodb1)
You are now ready to install the database.
2) Installing the Informix Database
In this section we will describe how to install the Informix
IDS 7.3 database. If you have additional Informix products
that you wish to install (e.g. an Informix 4GL Runtime or
other complimentary product) then these should be installed
before the Informix Dabatase.
Installation of such products is beyond the scope of this
article. Please refer to your Informix product documentation
for steps on installing your additional products prior to
the installation of the Informix IDS 7.3 database.
- Login to the OpenServer 6.0.0 server as root
- Change to the informix directory using:
# cd $INFORMIXDIR
- Informix IDS 7.3 is distributed as a cpio(C) archive.
You will need to copy the cpio archive from your
Informix Distribution media into the $INFORMIXDIR
directory. e.g. Lets assume the cpio archive is called
informix_ids.cpio
and its currently in /tmp on your server. To copy it
run:
# cp /tmp/informix_ids.cpio $INFORMIXDIR
- Extract the cpio archive as follows:
# cpio -icvd -I informix_ids.cpio
- Install the Informix IDS server using the "installserver"
script as follows:
# ./installserver
This script will prompt you for your Serial Number and Key,
it will install and set the correct permissions on
files and directories and on successful completion will
issue the message:
Installation of Informix Dynamic Server complete.
Your Informix server is installed and now needs to be configured.
3) Configuring your Informix Server
Once your have successfully installed your Informix database you
will still need to configure it. To configure the database
do the following:
- Log into the OpenServer 6.0.0 system as root
- Add the following entry for Informix to the /etc/services
(services(SFF)) file using your favourite editor:
kifos 1801/tcp
- Edit the Informix sqlhosts file ($INFORMIXDIR/etc/sqlhosts)
file and add the entries:
scodb1 ontlitcp scopaddy kifos
scodb1_shm onipcshm scopaddy srv_agent
where scopaddy should be replaced by the hostname of your
OpenServer 6.0.0 server.
- Create the Informix Root Database using:
# mkdir /usr1
# touch /usr1/rootdbs
# chmod 0666 /usr1/rootdbs
# chown informix:informix /usr1/rootdbs
NOTE:
We have chosen to create the database in /usr1 but you can
choose any location for the database once you make the correct
changes to the configuration below.
- Using your favourite editor make the following changes to the
Informix Database Configuration File, $INFORMIXDIR/etc/onconfig.std :
ROOTPATH /usr1/rootdbs
ROOTSIZE 102400
PHYSFILE 5000
MSGPATH /u/informix/online.log
ALARMPROGRAM /u/informix/etc/log_full.sh
SYSALARMPROGRAM /u/informix/etc/evidence.sh
SERVERNUM 1
DBSERVERNAME scodb1
DBSERVERALIASES scodb1_shm
NETTYPE ipcshm,1,100,CPU
LOCKS 10000
BUFFERS 20000
SHMBASE 0x82000000L
DRLOSTFOUND /u/informix/etc/dr.lostfound
BAR_BSALIB_PATH /u/informix/lib/libbsa.so
NOTE:
You may wish to modify some of the parameters such as ROOTSIZE,
PHYSFILE, LOCKS and BUFFERS to meet your own requirements.
- Create a symbolic link for one of the Informix libraries using:
# ln -s /u/informix/lib/libbsa.so /u/informix/lib/ibsad001.so
- Copy sm_versions.std to sm_versions using:
cp $INFORMIXDIR/etc/sm_versions.std $INFORMIXDIR/etc/sm_versions
Configuration is now complete.
4) Initialising the Informix Database
Once configuration is complete you can initialise the Informix
Database as follows:
- Log into the Openserver 6.0.0 server as the informix user
- Run the command:
$ oninit -iy
Your Informix Dabatase is now initialised and ready to use.
5) Testing access to the Informix Database
You can verify that you can access your Informix database using
the dbaccess command as follows:
- Log into the Openserver 6.0.0 server as informix
- Run the command:
$ dbaccess
From the menu select "Connection" and then "Connect". If your
database is configured then you will be prompted to
SELECT DATABASE SERVER>> and will be offered two choices:
scodb1
and
scodb1_shm
