                HCL Informix Client-SDK 4.50.FC10 PRODUCT RELEASE
                       HCL INFORMIX-ESQL/C Version 4.50.FC10

                      =================================

OS Information : Built on Windows Server 2016 x64.

Machine Specific Notes
======================

1.  This product supports the following compiler:

        Microsoft Visual Studio 2017

    This product is built on Windows 2016 using the following compiler
    from Microsoft Visual Studio 2017:

        Microsoft Visual C++ 2017

2.  Pluggable Authentication Module (PAM)

    PAM functionality is supported. Use of PAM can be enabled or disabled by 
    the system administrator. By default, IBM IDS will use the traditional 
    authentication mechanism in order to avoid widespread changes required 
    by the users.

3.  IPv6 Support 
  
    IDS 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 HCL 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 the nodename field of the
    server registry. Client applications should also use the same setting.

4.  ESQL/C support for static libraries

    ESQL/C product libraries are supported as both static and dynamic
    libraries. By default the script uses dynamic libraries.
    To use static libraries, the 'esql' script must be invoked with the
    -static option:

        esql -static

    Currently this -static option only works with the Microsoft Compiler.
    The static library name is isqlt09s.lib. This library is installed in
    $INFORMIXDIR/lib.
	
    This version of CSDK is built and certified with Microsoft Visual 
    Studio 2013 Version. Hence its recommended to use compiler version >= 2013.
    If you statically link (-static option) your ESQL/C application 
    with Microsoft Visual Studio Version older than 2013, you may receive 
    undefined symbol __report_rangecheckfailure() error. In order to avoid
    this error, you will need to use Microsoft Visual Studio Version 2013 or later.

5.  Connectivity 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 
       Connection.
    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.

6.  Host Variables (mlong datatype in Windows 64-bit)

    The mlong datatype is mapped to __int64 for Windows 64-bit. In Windows 
    32-bit and 32/64-bit UNIX, mlong is mapped to long datatype.
