Oracle Error Message

RMAN-06802: too many eligible base catalogs found

Reason for the Error

When trying to create a virtual catalog, more than one base catalog was found that is eligible to be the base catalog for this virtual catalog.

Solution

Revoke privileges so that the current catalog user has privileges on only one base catalog, then re-issue the CREATE VIRTUAL CATALOG command.
