=================================
MACHINE SPECIFIC NOTES
FOR
HCL Informix Database Server 14.10.FC10 PRODUCT RELEASE
ON Windows x64
DATE: 10 Mar 2023
=================================
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 Dynamic Server uninstallation
Due to an issue in installer tool, the registry entries created by
installer will not be automatically removed after
Informix Dynamic Server uninstall. The work around is to
cleanup existing registry entries under HKLM->Software->Informix->DBMS.
3. Installation Prerequisite on Windows 2016 or Later Versions
User may need to temporarily turn off User Account Control(UAC) security
before you install Informix Dynamic Server.
For information about how to create groups, add users to groups, and
turn off User Account Control, see your Windows documentation.
4. Informix Dynamic 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 8.0.55.26a, the Informix
server installation will upgrade the GSKit on your machine to
version 8.0.55.26a. If GSKit is not installed, the Informix
server installation will install GSKit in the directory
\Program Files\ibm\gsk8_64 on your machine.
b. The GSKit installation directory must have 35 MB of free disk space.
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
=============
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 the HCL Informix Backup and Restore Guide.
2. IPv6 Support
The Informix Dynamic 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)
HCL 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 HCL 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 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 configuration 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, ISQL)
can only connect to the Informix Dynamic 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. 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 Dynamic Server configuration parameters in the configuration
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.
9. Secure Sockets Layer
Informix Dynamic Server uses the libraries and utilities provided by
the IBM Global Security Kit (GSKit) for Secure Sockets Layer (SSL)
communication.
10. Simple Password Communications Support Module
The name of the HCL Informix dynamic link library for Simple
Password CSM on Windows is libixspw.dll. This dynamic link library
is installed in %INFORMIXDIR%\bin.
Features not supported
======================
1. Web Feature Service Database Extension
2. Mapped users
3. Rolling upgrades to Informix Dynamic Server version 14.10.xC2 and 14.10.xC6
are not supported.
Rolling upgrades are not supported in Informix Dynamic Server version
14.10.xC2 and 14.10.xC6. Migration to this version from a previous version
requires 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."
4. Support for Communication Support Module (CSM) is removed starting
Informix Server 14.10.xC9 . You should use Secure Sockets Layer
(SSL)/Transport Layer Security (TLS) instead.
