You delete a component instance by referring to the component's ID that is displayed when you view the component hierarchy.
To delete a component from the component hierarchy, go to EPM_ORACLE_INSTANCE/bin and run the following command:
epmsys_registry deletecomponent #componentID
where componentID is the component's ID that you found when you viewed the component hierarchy.
On UNIX, run:
epmsys_registry.sh deletecomponent \#componentID
Deleting a node does not delete its children.
If you are deleting a product node, first delete all the children of the node and then delete the product node.
Ensure that you delete the correct component.
