Solution for Cognos test data source xqe-jdb-0004 error

When we test the data source with Cognos, many users encounter errors that cannot be loaded by the database driver. For example, if we're using DB2, that means we can't load com.ibm.db2.jcc.DB2Driver.

The solution is simple:

1. Place the driver file:

Db2jcc4.jar

And

Db2jcc_license_cu.jar

Copy to

<install_cognos_directory>/v5dataserver/lib

And

<install_cognos_directory>/webapps/p2pd/web-inf/lib under

2. Then remember to restart the Cognos service to resolve this issue.
