Installation instructions
To install the OpenAdmin Tool Community Edition:
  1. Install and set up a working web server that is configured to serve PHP pages. For more information, see the Installation notes section.

    For further help, consult the web server product documentation for installation instructions, or contact the product customer service representatives for assistance.

  2. Update the PHP configuration file (php.ini):
    1. Open the php.ini file for editing.

      If you are using the XAMPP package:

      • Windows: Edit the php.ini file in the apache/bin folder, not in the php folder.
      • Linux: Edit the php.ini file in the /etc folder.
      • Mac OS X: Edit the php.ini file in the /Applications/xampp/etc folder.

      If you are not sure about the location of the correct php.ini configuration file, run the phpinfo() command within a PHP script on your web server to determine the location of the correct php.ini file.

    2. Add the following two lines after the extension=php_pdo.dll line to the "extension" section of the configuration file:
      If these lines are already present, remove any comment indicators from in front of them.
    3. Modify the memory_limit parameter to be at least 256 MB.
  3. Install Informix Connect or Client SDK.
  4. Extract the OAT package into your web server document root directory rootdir/OATINSTALL. For example:
    • Windows: C:\xampp\htdocs\oat
    • UNIX or Linux:/usr/local/apache2/htdocs/oat
    • Mac OS X: /Applications/xampp/htdocs/oat
    Important: For security reasons, set password protection for the OAT administration web pages. For more information and an example, see Providing password protection for the Admin configuration pages: Apache example in the OAT Help or in the Informix information center at
  5. UNIX, Linux, or Mac OS X users: Change the user or group ownership and permissions on the OAT directories.
    1. Determine which user and group run the Apache (HTTPd) server from the httpd.conf file.
    2. Change ownership for each OAT subdirectory to the user and group that run the Apache (HTTPd) server.
    3. Grant write permissions to all OAT subdirectories and files.

      Following is the syntax for changing the ownership and permissions:

      chown user:group OATINSTALL; chmod +w OATINSTALL;

      Where OATINSTALL is the root directory for OAT, which is the same directory where you extracted the OAT package.

  6. In the web server environment, set the INFORMIXDIR environment variable to the Informix Connect or the Client SDK installation location.
    • Windows: In the Control Panel, click System. In the System Properties dialog box, click the Advanced tab, and then click Environment Variables. Add or edit the system variable INFORMIXDIR.
    • UNIX, Linux, and Mac OS X: Set the environment variable in the shell.
  7. Start the web server.

    If you started the web server before you modified the php.ini file or before you set the INFORMIXDIR environment variable in the environment, restart the web server for the changes to take effect.

  8. To start the OAT installer, go to http://SERVERNAME/OATINSTALL/install


    • SERVERNAME is the name of the server where the web server is running
    • OATINSTALL is the location of OAT within your web server document root directory, where you extracted the OAT package.

    For example: http://localhost/oat/install

  9. Follow the instructions in the OAT installation screens:
    1. Read and accept the license agreement.
    2. Verify that all the required PHP modules are installed. If so, click Next; if not, check your PHP installation.
    3. Modify and verify the following configuration parameters:
      • LANG: Specify the default language for the application screens.
      • CONNDBDIR: Set the directory for the connections database.
        Important: For security purposes, specify a secure directory for the connections.db file. Do not use the web server document root directory. Additionally, ensure that the directory in which the connections.db file is located is accessible by the user who runs Apache.
      • BASEURL: Specify the root URL used to start OAT: http://SERVERNAME/OATINSTALL

        For example: http://localhost:8080/OAT

      • HOMEDIR: Verify the directory into which you extracted the installation package.
      • SECURESQL: Specify whether to prompt for login credentials when you use the SQLToolbox.
      • INFORMIXCONTIME: Specify the number of seconds that OAT waits to connect to the database server before OAT returns an error.
      • INFORMIXCONRETRY: Specify the number of times that OAT attempts to connect to the database server during the connect time that is specified by the INFORMIXCONTIME configuration parameter.
    4. To create the connections database, click Next. The connections database is created. Click Next to continue.
    5. Select the plug-ins to install and accept the plug-in license agreements.
  10. Optional: To access a database with a locale that is not included in Client SDK, install the locale by using the IBM Informix International Language Supplement (ILS). OAT requires the UTF-8 locales for all the databases that you access through OAT. After you install OAT, install ILS on the computer where OAT is installed, in the Informix Connect or Client SDK directory. Use ILS to install the additional locale, including the UTF-8 version, in the Informix Connect or Client SDK directory that OAT is using. The database name must be in English characters.
  11. When the installation is completed, go to the OAT root URL: http://SERVERNAME/OATINSTALL.
  12. On the Login page, select Admin and then expand Manage Connections to add an Informix 11.10 (or later) connection to the default group, or to create a group.

    If you are using an Informix Connect or Client SDK version earlier than V3.0, for each new connection that you add, ensure that there is a corresponding SQLHOSTS entry for that connection on the web server.

    To connect to a server, after a connection is created, click Login. Click Get Servers to retrieve the list of connections that you created, and then select the server.

Uninstalling OAT after manually installing

Important: If you installed OAT with the Client SDK, see the topic in the Informix information center on Uninstalling the OpenAdmin Tool (OAT) for Informix after installing it with the Client SDK: . Do not remove OAT by manually deleting the files.

To uninstall OpenAdmin Tool Community Edition manually, delete the OATINSTALL directory.

Upgrading from a previous version of OAT

To upgrade to OpenAdmin Tool Community Edition v3.15 from a previous version, uninstall the old version and install the new version in the same directory. OAT v2.20 and later preserves the connection database information.

Installation notes

The following section provides more information about installing and configuring OAT and provides other support resources.
DBSPACETEMP configuration parameter
You must define an appropriate value for the DBSPACETEMP configuration parameter for all the database servers that you want to use for OAT before you use OAT.
Avoiding page timeout errors

Set the Informix Connect or Client SDK variables INFORMIXCONRETRY and INFORMIXCONTIME to avoid page timeout errors for invalid connection information. The recommended settings are:

XAMPP package
For a manual installation, the XAMPP package is an easy-to-install Apache distribution that contains MySQL, PHP, and Perl. You can download the XAMPP package from the following website:

Informix PDO driver
The following IBM developerWorks article contains useful information to assist with building an Informix PDO driver: A step-by-step how-to guide to install, configure, and test a Linux, Apache, Informix, and PHP server:

Configuring connectivity for high availability clusters

If you are using the high availability clusters features from OAT to start and stop secondary servers or to add SD secondary servers, you must configure the following daemons on the Informix server:

  • xinetd or inetd:
    • Linux - xinetd daemon.
    • UNIX - inetd daemon: See your operating system information.
  • idsd daemon: Installed with IBM Informix 11.50 and later. This file is in the $INFORMIXDIR/bin directory. For information and examples for configuring the idsd daemon, see Configuring connectivity for high availability clusters in the OAT HELP or in the Informix information center at

    The idsd daemon requires Informix 11.50 or later. Also, the idsd daemon is not currently available on Mac OS X or Windows. Without the idsd daemon, the high availability cluster management interface is available in OAT, but the feature set is limited.

Adding a plug-in to OAT

You can add plug-ins that are created by IBM or by other organizations to OAT. Plug-ins that are created by IBM are included in the automated and manual installations for OAT. For instructions on installing a plug-in from another organization, see Installing a plug-in for OAT in the OAT HELP or in the Informix information center at .
