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
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.
4. IBM 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 7.0.4.27, IDS will upgrade the
GSKit on your machine to version 7.0.4.27. If GSKit is not
installed, IDS will install GSKit in \Program Files\ibm\gsk7
directory on your machine.
b. The GSKit installation directory must have 25 MB of free disk space.
The GSKit needs to be deployed correctly in using the encryption
functionality on a 64-bit machine. This requires a 32-bit machine to be
used for extracting the GSKit binaries to be deployed on the 64-bit
machine on which IDS was installed. Please follow the instructions below:
1. On a 32-bit machine, perform these tasks:
a. Create a temporary directory, e.g. C:\temp\gskit.
b. Change directory to that temporary directory, and copy
gsk7d_7.0.4.27_win32.exe from %INFORMIXDIR%\gskit directory
on the 64-bit machine.
c. Run this command:
..\gsk7d_7.0.4.27_win32.exe . /D
2. On the 64-bit machine, perform these tasks:
a. Create a directory named temp under the %INFORMIXDIR%\gskit
directory.
b. Copy C:\temp\gskit\* from the 32-bit machine to the
%INFORMIXDIR%\gskit\temp directory on the 64-bit machine.
c. From the %INFORMIXDIR%\gskit directory, run this command:
installgskit.bat GSKIT7

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:
/3GB
Feature Notes (alphabetized by feature)
=============
1. Informix Interface for TSM
The Informix Interface DLL for TSM is installed as
%INFORMIXDIR%\bin\libtxbsa.dll
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 IDS 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
registry.
4. J/Foundation (Java in the Server)
J/Foundation supports the JRE 5.0 release from IBM Corporation.
The JRE 5.0 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
follows:
JVPJAVAHOME <jvphome>/jre
where <jvphome> is %INFORMIXDIR%\extend\krakatoa
For IBM Informix Dynamic Server ONCONFIG settings for J/Foundation,
refer to "onconfig.std" in %INFORMIXDIR%\etc.
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 Dynamic
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 IDS 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
BAR_BSALIB_PATH ONCONFIG parameter.
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 Dynamic Server uses the libraries and utilities provided by
the IBM Global Security Kit (GSKit) for Secure Sockets Layer (SSL)
communication. The GSKit provides iKeyman utility (gsk7cmd, gsk7ikm)
and a non-java utility (gsk7capicmd) for managing digital certificates
necessary for SSL communication.
a. Product prerequisite for iKeyman utility:
The iKeyman utility requires the IBM Java Runtime Environment
(JRE) or IBM Java Development Kit (JDK) version 1.3.1, 1.4.1 or
higher with the Java Cryptography Extension (JCE) security package.
b. Environment for iKeyman utility:
- JAVA_HOME must be set to the JRE/JDK installation directory
- PATH must include <JRE/JDK installation>\jre\bin
- CLASSPATH must include <GSKit installation>\classes\cfwk.zip,
<GSKit installation>\classes\gsk7cls.jar and
<JRE/JDK installation>\jre\lib\ext\ibmpkcs11.jar
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.
