Unable to connect oracle as sysdba tables have been dropped I have a script which lists all tables belonging to the user and executes DROP for all of them.
By mistake, I logged in oracle with 'sys as sysdba' and ran above script. Due to which all sysdba tables are dropped.
Now i can not startup database instance. In alert log, it gives following error:

Sat Jul 20 15:28:21 2013
Errors in file orcl_ora_4276.trc:
ORA-00942: table or view does not exist
Error 942 happened during db open, shutting down database
USER: terminating instance due to error 942

I tried to flashback one droppd table, but it is giving error:

SQL&gt; alter database open;
alter database open
*
ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced
SQL&gt; FLASHBACK TABLE MAP_OBJECT TO BEFORE DROP;
ERROR:
ORA-03114: not connected to ORACLE

Please suggest if there is any way to restore all these tables.
Or if creating new database is the only way?
This is probably as complete a way of killing an Oracle database as you could wish for. The sys tables contain all the metadata about every object in the database -- objects, segments, extents ... so the database now contains no information on what user tables it stores, including the tables that store the data about that.

New database, I think.

And no more sys connection accidents.
