The information provided here is for example purposes only. We recommend that you refer to the product documentation for definitive information about installing and configuring the product.

Users and groups

Create a group and a user named informix

   groupadd informix
   useradd -g informix -m informix

Installing Informix

You have to have a disk partition (or a separate disk) to run Informix. The partition used for this example is on the UnixWare 7 disk at partition entry 3 (device node /unixware/dev/rdsk/c0b0t0d0p3). Change owner and group for this partition to informix, and. mode to 666.

Mount the CD under /cdrom

   mount -F cdfs -r /dev/cdrom/cdrom1 /cdrom

Become a Linux user by typing linux, and install the Informix server
```
   rpm --nodep --install /unixware/cdrom/XPS/XPS_SERVER/xps-8.31.UC1-1.i386.rpm
```
The --nodep switch is necessary because of a dependency on an older libncurses library.

Install the binaries as the UnixWare 7 root user:

   cd /opt/informix
   export INFORMIXDIR=/opt/informix
   ./installonline

Create an /opt/informix/etc/informix.rc file with the contents:

   export INFORMIXDIR=/opt/informix
   export INFORMIXSERVER=systemname.1
   export ONCONFIG=onconfig.std
   export PATH=$PATH:/opt/informix/bin

In /opt/informix/etc, edit edit onconfig.std so that the modified lines read:

   ROOTPATH        /unixware/dev/rdsk/c0b0t0d0p3
   DBSERVERNAME    systemname

Edit sqlhosts so it contains this one line This is for shared memory communication
```
   systemname.1 onipcshm        systemname   systemname.1
```
Login as the informix user
```
   /linux/bin/su - informix
```
Then run the initialization program for the database
```
   xctl -C oninit -iy
```
You can check installation progress by looking at the last entries in the log.
```
   tail -f /opt/informix/online.log
```
And confirm Informix is running by typing
```
   xctl onstat
```
(use xctl onstat --help to view other possible commands.)
To shut down the database use:
```
   xctl onmode -ky
```
There is a log file in /opt/informix/online.log, and sometimes a file called stdout.#.1 or stdout.systemname.1 in /linux. Also /INFORMIXTMP is created.
