Description:

If Event Manager was improperly removed from CAPC or restored from a backup and you try to add or sync Event Manager back with CAPC you may get an error like:

"Adding Data Source Failed Data source is already registered to another Performance Center instance"

Solution:

To resolve this, follow the steps below:

  1. From Admin UI, remove EM datasource
  2. Remove all NPC related property from em.general table by running the following from the CAPC server:

    mysql -P3308 em

    DELETE from general where Attribute LIKE '%NPC.%';

  3. Restart the Event Manager service by running:

    /etc/init.d/caperfcenter_eventmanager restart

  4. Manually add Event Manager again by going to "Admin->Data Sources' and selecting "New"
  5. Allow Event Manager to sync with CAPC
