                            MACHINE SPECIFIC NOTES
                                    FOR
                IBM Informix Database Server 14.10.FC6 PRODUCT RELEASE
                               ON Windows x64
                               DATE: 07 Jun 2021
                      =================================

OS Information : Built on Windows 2016 x64.. Certified on
		  Windows 2019.

System Requirements
===================

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

        Microsoft Visual C++ 2017

2.  Informix Server uninstallation

    Due to an issue in installer tool, the registry entries created by
    installer will not be automatically removed after Informix server
    uninstall. The work around is to cleanup existing registry entries under
    HKLM->Software->Informix->DBMS.

3.  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 8.0.55.22, Informix server
          will upgrade the GSKit on your machine to version 8.0.55.22. If
          GSKit is not installed, Informix server will install GSKit in
          \Program Files\ibm\gsk8_64 directory on your machine.

       b. The GSKit installation directory must have 35 MB of free disk space.


4.  Installation Prerequisite on Windows 2016 or Later Versions

    User may need to temporarily turn off User Account Control(UAC) security
    before you install IBM Informix.

    For information about how to create groups, add users to groups, and
    turn off User Account Control, see your Windows documentation.

System Configuration
====================

1.  Location of Shared Memory

    The ONCONFIG variable SHMBASE is recommended to be set to the following:

        SHMBASE 0x80000000L

2.  Administrator permission for running server utilities

    On Windows, you must run any 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

        %INFORMIXDIR%\bin\libtxbsa.dll

    This interface is built with TSM API version 5.3.2.

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

2.  IPv6 Support

    The Informix database server supports Internet Protocol Version 6 (128 Bit
    Internet Addresses) as well as IPv4 (32 Bit Addresses).

    In order for the machine name that is 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 earlier version of Informix client and server
    products, assign each host name 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 the IPv4 address, then an explicit IPv4 address needs to be put in the
    nodename field of server registry.

3.  J/Foundation (Java in the Server)

    The IBM Runtime Environment, Java(TM) Technology Edition, Version 8.0
    release is installed in $INFORMIXDIR/extend/krakatoa/jre and should be
    used with the J/Foundation component.

    A Java user-defined routine (UDR) runs in a Java virtual processor. Use
    the VPCLASS configuration parameter to specify the number of virtual
    processors for the server. You configure Java virtual processors in
    the "Java configuration parameters" section of the onconfig configuration
    file. The default onconfig.std file is in the $INFORMIXDIR/etc directory.

    To develop Java UDRs for the server on this platform, use Java Platform,
    Standard Edition Development Kit (JDK) 8 or an earlier version according
    to Java compatibility guidelines. That kit can be downloaded from https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html.

4.  Large Memory Addressability (LMA)

    IBM Informix LMA provides the ability to support system configurations
    with greater than 4GB of RAM.

    The values for the following ONCONFIG parameters are increased from
    32-bit limit by LMA support:

        - The maximum number of buffers in BUFFERPOOL is 2147483647.

        - The maximum of LRU queues for lrus field in BUFFERPOOL is 512.

        - The DS_TOTAL_MEMORY, which is the total memory available for
          decision support memory, is only limited by the amount of virtual
          memory available. The sort memory comes out of the DS_TOTAL_MEMORY
          memory and hence there is no explicit limit on the amount of sort
          memory.

        - The read ahead parameter RA_PAGES is only limited by the number of
          buffers and therefore can be any value less than 2147483647. The
          "chunk" write algorithm is not dependent on the amount of buffers
          or shared memory and can write as many pages in a single I/O as
          possible.

        - The maximum size of any shared memory segment is 4398046511104 bytes.

        - The maximum value for SHMADD is 4294967296 kilobytes.

    Refer to IBM Informix Administrator's Reference manual for the information
    about the related configuration parameters setting.

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

          b. To enable an IBM Informix Data Server Client to connect to the database
             server, the NETTYPE entry 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 the database server
             through DRDA while supporting SQLI connections, you must add a
             DBSERVERALIASES entry to the ONCONFIG file that corresponds to
             the SQLHOSTS registry entry.

      To use IPC (interprocess communication) with named pipe:

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

    Remote 32-bit or 64-bit applications and tools (example: ESQL/C, 4GL, ISQL)
    can only connect to the IBM Informix Database Server using the TCP/IP
    protocol.

    Local 32-bit applications and tools can connect to the 64-bit server using
    either the TCP/IP or the IPC named pipe protocols.

7.  OnLine Backup and Restore (ON-Bar)

    ON-Bar uses the XBSA interface. 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 BAR_BSALIB_PATH parameter in the ONCONFIG file.

    For example, if you are using PSM:

         Set BAR_BSALIB_PATH to %INFORMIXDIR%\bin\libbsapsm.dll

    For example, if you are using TSM:

         Set BAR_BSALIB_PATH to %INFORMIXDIR%\bin\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)
    communication.

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
    %INFORMIXDIR%\bin.

10. XML User-Defined Routines

    You cannot run XML UDRs at large memory segments (VX class) on this
    platform.

    To avoid XML UDR execution failure, configue and adjust the following
    Informix server configuration parameters in the onconfig file:

        PRELOAD_DLL_FILE -
             Specify the path name for a shared library file that is
             pre-loaded when the server is started.

        BUFFERPOOL -
             Adjust the memory field to a lower value.

        SHMVIRTSIZE -
             Adjust it to a lower value.


Features not supported
======================

1.  Rolling upgrades to IDS version 14.10.xC2 and 14.10.xC6 are not supported.

    Rolling upgrades are not supported in IDS version 14.10.xC2 and 14.10.xC6.
    Migration to these versions from a previous version require changes to
    disk structures, and the conversion process is incompatible with a rolling
    upgrade. When upgrading HDR and RSS secondary servers to version 14.10.xC2
    or 14.10.xC6, you must follow the steps listed in the on-line documentation
    under "Migrating an offline cluster to a new major version."

2.  Web Feature Service Database Extension

3.  Mapped users
