This is an easy install guide of the informix database on raspberry-pi. It is mostly a 1:1 from here.

Download Informix Developer Edition for Linux ARM v6 32. Must be that version and must be ARM enabled.

You can use this link.

• Copy the tar file for installation to your raspberry temporary folder.

scp examplefile yourusername@yourserver:/tmp

I.e. in my case:

scp ids.12.10.UC12DE.linuxARM32v6.tar pi@raspberrypi:/tmp

• Then login into your raspberry and do the following:
• Create a temporary folder for the Informix install files

mkdir /tmp/ifxinstall

• Change directory to that folder:

cd /tmp/ifxinstall

• Extract the Informix tar file - wait a bit until everything is unpacked and do not interrupt:

tar xvf /tmp/ids.12.10.UC12DE.linuxARM32v6.tar

• create a new group informix:

sudo addgroup informix

• (Ref:1) Create a new user informix (with the primary group informix). During this step you will be asked for a password for informix. Please take a note of that password. You will need it later.

sudo adduser --ingroup informix informix

• Make sure to add the user informix to the /etc/sudoers file by adding the following line by using the ‘sudo visudo’ command:

informix ALL=(ALL) NOPASSWD: ALL

• Run the installation script

sudo ./ids_install

Follow the UI and enter the following:

• accept -> 1 RET
• RET
• specify directory where to install the products: /opt/IBM/informix1210UC4DE
• accept -> 1 (wait a long bit and do not interrupt)

• Optional: As soon as the installation has successfully finished, you can delete the ifxinstall folder and the Informix install tar file if you want.

rm -rf /tmp/ifxinstall
rm /tmp/ids.12.10.UC4DE.Linux-ARM6.tar

• Optional, but highly recommended: create the following symbolic link:

sudo ln -s /opt/IBM/informix1210UC4DE /opt/IBM/informix

• Create the folder which will later contain the Informix database files:

sudo mkdir /opt/IBM/ifxdata

• Set its ownership and permissions:

sudo chown informix:informix /opt/IBM/ifxdata
sudo chmod 770 /opt/IBM/ifxdata

• Login as the informix user

  su informix 
      

  And enter your password of (Ref:1).

• Set the $INFORMIXDIR environment variable to point to the Informix install directory (actually to the symbolic link):

  export INFORMIXDIR=/opt/IBM/informix
      

• Extend the $PATH environment variable:

  export PATH=$PATH:$INFORMIXDIR/bin
      

• Set the $INFORMIXSERVER environment variable (you can choose any name here, but let’s use ol_informix1210 for now to keep it simple):

  export INFORMIXSERVER=ol_informix1210
      

• Create a new Informix configuration file:

  cp $INFORMIXDIR/etc/onconfig.std $INFORMIXDIR/etc/onconfig
      

• Create a new Informix hosts definition file:

  cp $INFORMIXDIR/etc/sqlhosts.demo $INFORMIXDIR/etc/sqlhosts
      

• Edit the file $INFORMIXDIR/etc/onconfig (with nano, vi or any other editor)

  I.e. enter the file via the nano editor (or any other editor)

  nano $INFORMIXDIR/etc/onconfig
      

  And apply the following changes (use the search option ^W (control-W)):

  ROOTPATH /opt/IBM/ifxdata/rootdbs
  DBSERVERNAME	ol_informix1210
  LTAPEDEV	/dev/null
  TAPEDEV		/dev/null
  LOGFILES	10
      

  Save the file and exit the editor (Control-O RET; Control-X).

• Edit the file $INFORMIXDIR/etc/sqlhosts

  nano $INFORMIXDIR/etc/sqlhosts
      

  And add the following line:

  ol_informix1210	onsoctcp	localhost	9088
      

  Note: 9088 is the port which will be used by Informix for the client/server communication. You can choose any available port you want. Save the file and exit the editor.

• Create an empty database file and set the correct access mode:

touch /opt/IBM/ifxdata/rootdbs
chmod 660 /opt/IBM/ifxdata/rootdbs

• Now we are ready to initialize Informix for the first time:

  oninit -iv
      

  The first initialization will take a few minutes and it will create a few system databases automatically. You can monitor the pogress by doing the following:

  tail -f /opt/IBM/informix/tmp/online.log
      

  Please wait until you see the following entry in the online.log file before you continue:

  ‘sysadmin’ database built successfully
