The false illusion of Cognos due to java_home conflict

Cognos installation and configuration is not very complex, but for the initial installation of the user, still need to pay attention to some details, such as JDK problem, today we will explain this problem

Scenario 1:

As a developer, a lot of people are terrorize master of everything, inevitably already installed in their own Java environment, and configured the JAVA_HOME environment variable, install again

At Cognos, there were some mistakes, like cfg-err-0106.

The reason of course is because of the java_home problem, if you try to delete the Java_home variable, the problem may be solved

Scenario 2:

If the server is public, Java_home cannot be deleted and may experience the following error

The above error is easy to think of as a cryptographic information error, so we took the go to D:\Program Files (x86) \ibm\cognos\c10\configuration directory Delete

Start the Cognos configuration again but the error still exists, using the exclusion method, the problem is obviously not the above reasons, so from the wrong start, from the above error message we can see

To have such a line

So I thought of my own installation of the JDK is missing some of the official Cognos jar, and then entered into the D:\Program Files (x86) \ibm\cognos\c10\bin\jre\7.0\lib\ext directory view, such as

is shown

Return to the Ext directory of the JDK you installed

By contrast, the solution is to copy all the jars under the Ext folder in the Cognos installation directory to the corresponding Ext directory in the local Java path, and if duplicates occur, select overwrite

After the above operation, the problem can be solved
