After creating or recreating an Oracle Database RAC agent (DBO agent), the dashboard is not showing any data, most of the components are showing "There is no data to display".  The following error is found in the DBO logs:

com.quest.qsi.fason.oracle.collection.processor.DBOInstanceProcessor - Failed to run DBOSCWaitEventStatisticsProcessor processor of DBO_Subcategories_Wait collection of DBO-RAC-NODE-host-intance instance.
java.lang.RuntimeException: Failed to execute collection [DBO_Subcategories_Wait], reason=com.quest.qsi.fason.oracle.agent.rac.parent.RacAgent cannot be cast to com.quest.qsi.fason.oracle.asm.agent.ASMAgent

1. Go to Administration | Agents | Agent Status
2. Recreate the ASM agent to have a name that is different from the RAC agent.
3. Select the RAC instance agent | Edit Properties |  Modify the private properties for this agent
4. Look for "ASM agent name" and set it to the new ASM agent name that you have created in step 2
5. Deactivate and activate the agent
