ARC1232 RESTORE FALLBACK option disabled since re-hashing data
When re-hashing data rows during a RESTORE/COPY operation, ARC does not create fallback subtables (if needed) until the re-hashing phase has been completed. If the user has either explicitly or implicitly invoked the RESTORE FALLBACK option, the option will be disabled for the remainder of processing for this utility statement.
Technically, the RESTORE FALLBACK modifier is not a user-specifiable option on the COPY statement. Instead, COPY usually behaves as if the equivalent RESTORE option were always in effect. In this case, however, the option is disabled. This is a WARNING error.
No problem. ARC will build fallback as soon as all of the primary data has been re-hashed, re- distributed, and sorted.
