***IBM has announced transition of IBM Informix Server 12.10 and CSDK 4.10 to IBM Extended Support effective April, 2026. Clients are encouraged to move to the latest version or release of the program or acquire Extended Support.*** 

 

 


Informix Client SDK and Informix Connect run on most systems that have a UNIX, Linux, or Windows operating system.

Starting with version 4.50.xC4, stand-alone installation of the Client SDK requires a minimum version of OpenSSL 1.0.x to be installed on the system. Refer to https://www.openssl.org for more information on OpenSSL.

 

 

Java JRE was removed from the IBM Informix distribution starting with 14.10.FC11 and in 15.0: 

  • Customers will need to pre-install the Java JRE v1.8 or greater for use with 14.10 Informix products
  • Customers will need to pre-install the Java JRE v11 or v17 for use with 15.0 Informix products
  • Java v11 -  v21 is required for InformixHQ 2.4.1 and greater
  • Java v11 is required for Informix 14.10.FC11W1 and greater and 15.0

** Following system libraries are needed for IBM Informix version 14.10.FC9, 14.10.FC10, and 14.10.FC11 to run on Red Hat Linux 9. (This workaround is not needed in 14.10.FC11W1 and later). Higher versions of same libraries are installed on Red Hat Linux 9. As a workaround, symbolic links to those libraries need to be created.

      Libraries needed for Informix:
          libncurses.so.5
          libtinfo.so.5

      Libraries installed on Red Hat Linux 9:
         libncurses.so.6
         libtinfo.so.6

      Workaround:
          Run following commands as root user from /usr/lib64 directory.
               ln -s libncurses.so.6 libncurses.so.5

               ln -s libtinfo.so.6 libtinfo.so.5
