Installation instructions for applying the SSLv3 POODLE fix.

Part 1: For Windows servers where the Agent or Server component is installed.

1. Download the 32 bit IBM Java JRE (file name: ibm-java-jre-60-win-i386.zip, Size: 75 MB).
2. Stop the CccServer, CccQueue and CccAgent Windows services.
3. Rename the <INSTALLDIR>\Common\java directory to <INSTALLDIR>\Common\java.orig
4. Unpack the content of the ibm-java-jre-60-win-i386.zip file to <INSTALLDIR>\Common\java
5. Start the CccAgent, CccQueue and CccServer Windows services.
6. Validate the installation by testing the connectivity to the agent using the CCC Client.

Part 2: For Windows servers where any Commmand Center component is installed.

In addition to the steps described in part 1, please disable SSLv3 for the Windows servers running any IBM Cognos Command Center components. Please refer to Microsoft Security Advisory 300908 <https://technet.microsoft.com/en-us/library/security/3009008.aspx&gt;.

Part 3: For UNIX servers where the Agent component is installed

Please update your Java Runtime Environment to a version that contains a fix for the SSLv3 POODLE vulnerability and reconfigure the Agent installation to use this Java Runtime Environment.

Workarounds and Mitigations

Disable SSLv3 for the Windows servers running any IBM Cognos Command Center components. Please refer to Microsoft Security Advisory 300908 <https://technet.microsoft.com/en-us/library/security/3009008.aspx&gt;.
