Known problems

Up-to-date information about the known problems for Informix 12.10.xC4W1 is available at http://www.ibm.com/support/docview.wss?uid=swg27041880.

At time of publication, the following problems were known:
  • If you uninstall Informix version 11.50, restart the computer before you install another version of Informix

    If you install Informix on a computer where you previously uninstalled Informix version 11.50, the new installation might fail because the Informix database server Message Service (msgserv.exe) does not start.

    To avoid this problem, restart the computer before you install Informix again.

  • Windows firewall exception is needed before installation

    Before you install Informix on Windows operating systems, make a Windows firewall exception for the TCP listening port that is used by Informix. By default, the Informix port is 9088; however, you can specify a different port number during installation.

  • Removing users when you uninstall the database server

    If there are multiple installations of the product on the computer, and you are uninstalling one of the products, be careful when you use the Remove users and groups option. Do not remove users or groups that are required by the other installations of the product. If you remove users or groups that are required by the other products, the other products will not start or they will be inoperable.

  • Starting Informix instances

    To start an Informix instance, use the instance shortcut that is in the Informix program group. To start a 32-bit version of Informix on a 64-bit operating system (such as Windows 7), right-click the shortcut, and click Run as administrator.
