In Oracle, as of version 11.2, you can't rename a schema (=user). See this discussion on AskTom for a workaround: you would export the user, reimport with the good name (using FROMUSER and TOUSER). All references (if any) in pl/sql code will have to be updated manually. Grants and public synonyms will have to be recreated separately.

  • @benoit: I was really curious to see if it's possible to rename a schema, but it looked too easy :) – Vincent Mar 8 '11 at 12:52
  • If you think about it, it would be problematic since it would change the how every object in the schema is referenced. For one thing it would have to modify code making it no longer in sync with your source repository. – JOTN Mar 11 '11 at 23:36
