The ORA-00980 means that the synonym exists, but the table or view it
is based on - doesn't exist.
Recreate the view and synonym (just in case):
-- This part needs to be executed by SYS.
-- In case when you are re-creating these views, use "create or
replace view" variation:
create view sys.x_$ksled as select * from x$ksled;
grant select on sys.x_$ksled to PUBLIC;
create public synonym x$ksled for sys.x_$ksled;
create view sys.x_$kslei as select * from x$kslei;
grant select on sys.x_$kslei to PUBLIC;
create public synonym x$kslei for sys.x_$kslei;
