Known problems

Up-to-date information about the known problems for Informix 12.10.xC1 is available at http://www.ibm.com/support/docview.wss?uid=swg27037713.

At time of publication, the following problems were known:

• Restart the computer after uninstalling Informix version 11.50 before you install any version of Informix again

  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 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.
