ORA-01552: cannot use system rollback segment for non-system tablespace 'string'
Cause: Tried to use the system rollback segment for operations involving
non-system tablespace. If this is a clone database then this will happen when

attempting any data modification outside of the system tablespace. Only the
system rollback segment can be online in a clone database.
Action: Create one or more private/public segment(s), shutdown and then
startup again. May need to modify the INIT.ORA parameter rollback_segments to
acquire private rollback segment. If this is a clone database being used for
tablspace point in time recovery then this operation is not allowed. If the
non-system tablespace has AUTO segment space management, then create an
undo tablespace.
