    For information about Microsoft service packs and patches, see the Microsoft
    Support web site at

3.  Enable Connections on Windows Vista

    To enable connections between database servers on the Vista operating
    system, you must enable network discovery and NetBIOS over TCP/IP.

    To enable connections:

    1) From the Control Panel, double-click Network and Sharing.
    2) In the Sharing and Discovery section of the Network and Sharing Center,
       click Network discovery and then Turn on network discovery.
    3) In the Network section, click View Status next to the Local Area
    4) In the Local Area Connection Status dialog box, click Properties.
    5) In the Local Area Connection Properties dialog box, choose the
       appropriate Internet Protocol Version and click Properties.
    6) In the Internet Protocol Version Properties dialog box, click Advanced.
    7) On the WINS page of the Advanced TCP/IP Settings dialog box, click
       Enable NetBIOS over TCP/IP and then click OK.
    8) Continue clicking OK or Close until all dialog boxes are closed.

4.  IBM Informix Database Server uses the libraries and utilities provided by
    the IBM Global Security Kit (GSKit) for data encryption and Secure Sockets
    Layer (SSL) communication. The GSKit is bundled with the server and will
    be installed on your machine as part of the server installation process.
    Here are more details on the GSKit:

       a. The GSKit is also bundled with other IBM products and might
          already be present on your machine. If the GSKit was previously
          installed, but is older than version, Informix server will 
          upgrade the GSKit on your machine to version If GSKit is 
          not installed, Informix server will install GSKit in 
          \Program Files\ibm\gsk8 directory on your machine.

       b. The GSKit installation directory must have 25 MB of free disk space.

5.  Using BladeManager 4.20

    If the GUI BladeManager wblademgr.exe is used, Microsoft .NET Framework v2 
    or higher is required to be installed on the system.

Check the following web site for the latest Windows system requirements
for IBM Informix Database Server:

System Configuration
1.  Location of Shared Memory
    The ONCONFIG variable SHMBASE is recommended to be set to the following:
        SHMBASE 0xc000000L

2.  Support maximum shared memory

    The database server can access shared-memory larger than two gigabytes 
    on Windows. However, you must enable this feature with an entry in the 
    Windows boot file.

    To add the entry, edit the boot.ini file (located in the top level, or 
    root directory). You can either add a new boot option or use the currently 
    existing boot option. To enable support for more than two gigabytes, add 
    the following text to the end of the boot line: 


3.  Administrator permission for running server utilities

    On Windows Vista, Windows 2008 and Windows 7, you must run many 
    server utility commands with administrator permission: for example, 
    the 'oninit -iy' command to initialize the server.

    To run Informix utility commands as an administrator, from the Start menu, 
    choose the Informix server name and then choose "Run as administrator". 
    A command prompt with administrator permissions opens.

Feature Notes  (alphabetized by feature)

1.  Informix Interface for TSM

    The Informix Interface DLL for TSM is installed as 

    This interface is built with TSM API version 5.1.6.

    To use Tivoli Storage Manager with Informix databases, refer to IBM 
    Informix Backup and Restore Guide.

2.  Informix Storage Manager (ISM 2.2)

    The product is installed with Informix Server at location of %ISMDIR%. 
    The XBSA shared library name is %ISMDIR%\bin\libbsa.dll.

    To use Informix Storage Manager with Informix databases, refer to IBM 
    Informix Backup and Restore Guide.

3.  IPv6 Support 

    IBM Informix Server supports Internet Protocol Version 6 (128 Bit Internet
    Addresses) as well as IPv4 (32 Bit Addresses).

    In order for the machine name specified in the SQLHOSTS registry to resolve
    to the correct IP address, the name services files on the Operating System
    should be correctly configured.

    For compatibility with older IBM Informix client and server products,
    assign the same hostname with both an IPv4 address and an IPv6 address.
    If the listener needs to be bound to an IPv4 address and the name services
    resolve the name in the order of the IPv6 address followed by IPv4 address,
    then an explicit IPv4 address needs to be put in nodename field of server

4.  J/Foundation (Java in the Server)
    J/Foundation supports the JRE 6.0 release from IBM Corporation.

    The JRE 6.0 is available under %INFORMIXDIR%\extend\krakatoa\jre and
    should be used with J/Foundation.

    To use this JRE, set the value of the ONCONFIG variable JVPJAVAHOME as

        JVPJAVAHOME    <jvphome>/jre
            where <jvphome> is %INFORMIXDIR%\extend\krakatoa

    For IBM Informix Database Server ONCONFIG settings for J/Foundation,
    refer to "onconfig.std" in %INFORMIXDIR%\etc.

    Java Attach API
    There is a known defect (IZ73533) in the IBM Java SE Runtime Environment SR7
    where if the Attach API is enabled, it causes high CPU utilization. In order
    to avoid this behavior, the Attach API has been disabled by setting the
    following server ONCONFIG parameter:

5.  LDAP Authentication 

    This feature is set up and configured like the Pluggable Authentication
    Module (PAM) that is used on UNIX and Linux. Use the LDAP Authentication 
    Support module when you want to use an LDAP server to authenticate your 
    system users.

    The authentication module is a dynamic link library that resides in the 
    %INFORMIXDIR%\dbssodir\lib\security directory. The parameters of the module
    are listed in the %INFORMIXDIR%\dbssodir\pam.conf file. 

    The source code for a fully functional LDAP Authentication Module and 
    samples of the required configuration files are included in the 
    %INFORMIXDIR%\demo\authentication directory. You can modify the code for 
    your specific LDAP Authentication Support module.

6.  Network Protocols

    The following protocol(s)/interface(s) are supported on this platform:
      SOCKETS using TCP/IP
      IPC using named pipe

      To use SOCKETS with TCP/IP:

          a. NETTYPE in the ONCONFIG file and the value data of PROTOCOL in the
             SQLHOSTS registry entry must contain "onsoctcp"

          b. To enable an IBM Data Server Client to connect to Informix Database
             Server, NETTYPE in the ONCONFIG file and the value data of PROTOCOL
             in the SQLHOSTS registry entry must contain "drsoctcp"

             If a CLI or JCC client wants to connect to informix server via 
             DRDA while supporting SQLI connections you could add a 
             DBSERVERALIASES entry to ONCONFIG which corresponds to the 
             SQLHOSTS registry entry.

      To use IPC (interprocess communication) with named pipe:

          a. NETTYPE in the ONCONFIG file and the value data of PROTOCOL in the
             SQLHOSTS registry entry must contain "onipcnmp".
7.  OnLine Backup and Restore (ON-Bar)
    Some of the functions invoked by ON-Bar are in a dynamic link library 
    supplied by third party storage management vendors. For ON-Bar to access 
    these functions, you must specify the library name and location in the 

    For example, if you are using ISM: 

         Set BAR_BSALIB_PATH to %ISMDIR%\bin\libbsa.dll

    For example, if you are using TSM:

         Set BAR_BSALIB_PATH to %INFORMIXDIR%\lib\libtxbsa.dll 

8.  Secure Sockets Layer

    IBM Informix Database Server uses the libraries and utilities provided by
    the IBM Global Security Kit (GSKit) for Secure Sockets Layer (SSL)

9.  Simple Password Communications Support Module

    The name of the IBM Informix dynamic link library for Simple Password CSM
    on Windows is libixspw.dll. This dynamic link library is installed in

Features not supported

1.  Shared Disk Secondary Servers

2.  Mapped users
