Oracle : Ошибка ORA-34357

"(MXDSS10) %a %s %s\n%1p is not an alias of analytic workspace %2p."
*Cause: User attempted to use AW UNALIAS on a non-existent alias.
*Action: Make sure that the command specified the correct analytic
workspace and alias. The alias must have been assigned (using AW ALIAS)
during the current session and must not have been removed by
a previous AW UNALIAS or AW DETACH command.
