I want to drop the excess schemas that were created with the database.
We don't use any database features or add-ons. Is dropping them be ill advised? The schemas are ANONYMOUS, APEX_040200, APEX_PUBLIC_USER, APPQOSSYS, AUDSYS, CTXSYS, DIP, DVF, DVSYS, ORDSYS, ORDPLUGINS, ORDDATA, FLOWS_FILES, GSMADMIN_INTERNAL, GSMCATUSER, GSMUSER, LBACSYS, MDDATA, MDSYS, OJVMSYS, OLAPSYS, ORACLE_OCM, SYSBACKUP, SPATIAL_WFS_ADMIN_USR, SPATIAL_CSW_ADMIN_USR, SI_INFORMTN_SCHEMA, SCOTT, XS$NULL, XDB, WMSYS, SYSKM, SYSDG.
