I can't help myself. My R & D colleagues directly shut down the plug-in power supply when testing the IBM 3650 server ???
The next day, after some restart, oracle opened the error ORA-00600: internal error code, arguments: [4194], [53], [41], [], [], [], [], []
DBA for help
The absolute solution is to enable undo manual management and recreate the undo tablespace.
The procedure is as follows:
SQL> alter system set undo_management = MANUAL scope = spfile;
SQL> shutdown immediate;
SQL> startup mount;
SQL> alter database open;
SQL> create undo tablespace undotbs2 datafile '+ data' size 16 GB;
SQL> alter system set undo_management = AUTO scope = spfile;
SQL> alter system set undo_tablespace = undotbs2 scope = spfile;
SQL> shutdown immediate;
SQL> startup mount;
SQL> alter database open;
At this point, the database is started normally.
Rebuild the undo tablespace to avoid 4194 events, but the database is in the crash State at any time. To avoid unexpected downtime, export all the data to a new database.
Again, I would like to declare that the O & M SERVER should not think that power-off is easy. It is not a pc, and the pc cannot handle such a problem !!!
