This script installs Informix versions 11.70 and 12.10 in Ubuntu.

You need an installation file of Informix for one of the Informix versions supported (you can download no-charge versions from the [Informix downloads page] (http://www-01.ibm.com/software/data/informix/downloads.html)).

Run the script as root user and pass as the parameter the archive file of the Informix version that you want to install, for example:

$ ./ifx-install.sh iif.12.10.FC4IE.linux-x86_64.tar

The script will create the informix user needed for the Informix server if it does not exist with the password disabled, you can add a password after the installation as root with the command:

$ passwd informix

The Informix installation is done in the directory /opt/ibm/informix/${INFORMIX_VERSION}/ and the data directory (chunks and log files) are created under the informix user home:

/home/informix/
└── ${INFORMIX_VERSION}
    └── data
        ├── dbspaces
        │   └── rootdbs
        └── logs
            ├── online.con
            └── online.log

The ./config directory contains a common configuration file for the installation and a specific file for each version supported, you can change some installation values from these files. By default the TAPEDEV and LTAPEDEV values are set to /dev/null because this script is mainly created with software testing purposes so you will need to modify these values if you want to use the server for a more serious things.

The installation adds one new service to the /etc/services file automatically for each version installed.

$ cat /etc/services
# Local services
ifx1170    9087/tcp
ifx1210    9088/tcp
$

The installation creates a file with the environment variables needed to work with each version installed in /opt/ibm/informix/${INFORMIX_VERSION}/${INFORMIX_SERVER}.env, by default the informix server is ifx1170 and ifx1210 for the versions 11.70 and 12.10 respectively. For starting the server you need to switch to the informix user and load the environment file before use the informix commands:

$ su - informix
$ . /opt/ibm/informix/12.10/etc/ifx1210.env

then you can start the server:

$ oninit
$ onstat -

the last command onstat - gives you information about the status of the server that should be On-Line.

With the environment file loaded use the command:

$ onmode -ky
$ onstat -

now the onstat - command will give you a message like shared memory not initialized for INFORMIXSERVER that means that the server is not running.

No database is created by default. Please refer to the Informix documentation for that: [CREATE DATABASE statement] (http://www-01.ibm.com/support/knowledgecenter/SSGU8G_11.50.0/com.ibm.sqls.doc/ids_sqs_0368.htm).
