Cause

The error is caused by an incorrect Oracle JDBC (ojdbc) connection or a missing .jar file.

Environment

ICN and CM with Oracle Database

Resolving The Problem

  • Make sure the ORACLE_JDBC_DRIVER_PATH is set to the directory where odbc6.jar is located
    e.g. /users/app/nexus/oracle/jdbc/lib/
  • Make sure dms.jar and smplefan.jar exist in this directory.
  • After changing ORACLE_JDBC_DRIVER_PATH or the content of this directory the application server needs to be restarted.

NOTE: Only odbc6 related .jar files exist in the ORACLE_JDBC_DRIVER_PATH directory and odbc5 or odbc7 jar files should not be included.
