autofixup alter table upgrade including data -- can this be run on production database when users ar
I have another question on upgrading from 11.2.0.3 to 18.4 ... when i run the preupgrade tool -- one of the required actions is an AUTOFIXUP ... and says you must upgrade Oracle-Maintained tables usig prior versions of evolved types. Use ALTER TABLE . . . UPGRADE INCLUDING DATA... Can i run the preupgrade_fixups.sql on a production database while users are working ... and it will still be sometime before i can do the actual upgrade? or must i do the preupgrade_fixups.sql on a quiet database immediately prior to upgrading?
thanks in advance
