If you use Oracle for data source, import source, logging database, or the content store database, you must ensure that there is no conflict with the JDBC driver file. In earlier releases of Cognos 8, Oracle databases required a classes12.jar file. In Cognos 8 Version 8.2, Oracle databases require an ojdbc14.jar file.
To ensure that there is no conflict, check the c8_location\webapps\p2pd\WEB-INF\lib directory on each computer where Content Manager, the Application Tier, Framework Manager, or Metric Studio is installed. If both the classes12.jar file and the ojdbc14.jar file are present, you must delete the obsolete classes12.jar file.
