Cause: There are several causes for this message. It could be just an informational message and not an error message if the user canceled the Format operation.
Action: Check the EPC_ERROR.LOG for other underlying error messages, for example, failure to resolve database service name supplied to the formatter. (This could mean that the TNSNAMES.ORA file on the local node where the format code is executing does not contain an entry for the specified format database.) If the collection ID given in the error message is less than 0, then format processing probably did not get as far as accessing the format database. Retry the Format command and specify the -f parameter (that is, full rather than partial format) to reformat data that had already been formatted before the abort took place.
