When trying to add the Event Manager as a Data Source, I receive an error saying

Cause
If the Event Manager Data Source gets deleted from CAPC
(during a CAPC upgrade for instance) you will need to add it back into CAPC.
Performing a Data source test you might get "Data Source Test Successful"
However when you try to save the data Source you get the following error :
Adding Data Source Failed
Data source is already registered to another Performance Center instance
This error is caused by CAPC containing information about the original instance of the EM data source and when you try to add it again, CAPC wants to create a new instance.

Resolution
In order to have PC and EM back in sync, please do the following procedure
mysql em -unetqos -pnetqos
DELETE from em.general where Attribute LIKE '%NPC.%';

- From Admin UI, remove EM data source (if present).
- Remove all NPC related properties from em.general table in mysql:
mysql em -unetqos -pnetqos
DELETE from em.general where Attribute LIKE '%NPC.%';
exit
- Restart EM: service caperfcenter_eventmanager restart
- Manually add the EM data source again.
