You can configure your IBM® Content
Classification system to support addresses
and URLs that adhere to the IP version 6 (IPv6) protocol. After you
enable support for IPv6 addresses, IBM Content
Classification will no longer use IPv4
addresses for any socket communications. Support for the IPv6 protocol
is certified on Windows.
About this task
The Internet Explorer and Mozilla Firefox browsers handle
IPv6 addresses differently:
- Mozilla Firefox
- To run the Content Classification web
applications, you can specify either the IPv6 address or the host
name in the URL. For example:
http://[9842:6a52:086d::1]:19000/EntryPoint/
http://localhost:2121/ClassificationCenter/
- Internet Explorer
- To run the Content Classification web
applications, you cannot specify the IPv6 address in the URL. You
must specify the host name in the URL and ensure that the host name
is mapped to the IPv6 address in the Domain Name System (DNS). For
example:
http://jk_enterprises.com:19000/EntryPoint/
http://localhost:2121/ClassificationCenter/
If you specify
an IPv6 address in the URL, the message Invalid syntax error or Internet
Explorer cannot open the page is displayed.
To set up your Content Classification system to use only
IPv6 socket addresses:
Procedure
- Configure your operating system to support the IPv6 protocol. Ensure that the following mapping exists in the hosts file:
::1 localhost
For
further instructions, consult the documentation for your operating
system.
- On all servers where you installed a Content Classification component, create a
permanent system environment variable named ICM_IPV6 whose
value is 1.
- Edit the Management Console startup
script (ManagementConsole.bat on Windows or ManagementConsole.sh on AIX®, Linux,
or Solaris) in the Classification_Home\Bin\ManagementConsole directory. Add the Djava.net.preferIPv6Addresses=true and Djava.net.preferIPv4Stack=falsefollowing arguments
before the existing arguments, as follows:
start /min ..\..\Java60\jre\bin\java
-Djava.net.preferIPv6Addresses=true -Djava.net.preferIPv4Stack=false
-Xmx128m -cp "ManagementConsole-86.jar;..\..\Lib\Redist\axis-1_4\axis.jar;..\..\Lib\Redist\axis-1_4\wsdl4j-1.5.1.jar;..\..\Lib\Redist\axis-1_4\commons-logging-1.0.4.jar;..\..\Lib\Redist\axis-1_4\jaxrpc.jar;..\..\Lib\Redist\axis-1_4\commons-discovery-0.2.jar;..\..\Lib\Redist\axis-1_4\log4j-1.2.8.jar;..\..\Lib\Redist\axis-1_4\saaj.jar;"
-Dlog4j.configuration=managementconsole.ini com.banter.bsmc.console
- Restart all Content Classification servers
on which you enabled IPv6 support.
