Your current database uses dictionary-managed tablespaces. In running various performance tuning scripts, you have discovered that one of these tablespaces seems to have run out of space long before you calculated that it would. In tracking activity in the tablespace, you discover that the process of tables being created, then dropped and re-created with different storage settings, has been excessive.
