ORA-00474: SMON process terminated with error

Hi,

Sometimes you can get ” ORA-00474: SMON process terminated with error ” error.

Details of error are as follows.

Errors in file /<path>/diag/rdbms/<db_name>/<oracle_sid>/trace/<oracle_sid>_smon_<pid>.trc (incident=<NNNNN>):
ORA-00600: internal error code, arguments: [13011], [351384], [146850571], [7], [146850571], [4], [], [], [], [], [], []

ORA-00474: SMON process terminated with error
PMON (ospid: <pid>): terminating the instance due to error 474
Instance terminated by PMON, pid = <pid>

You should rebuild corrupted indexes:

SQL> ALTER INDEX SMON_SCN_TIME_TIM_IDX REBUILD ONLINE;
SQL> ALTER INDEX SMON_SCN_TIME_SCN_IDX REBUILD  ONLINE;

 

Drop index and create them again.

 

SQL> DROP INDEX "SYS"."SMON_SCN_TIME_TIM_IDX";
SQL> DROP INDEX "SYS"."SMON_SCN_TIME_SCN_IDX";
SQL> CREATE UNIQUE INDEX "SYS"."SMON_SCN_TIME_TIM_IDX" ON "SYS"."SMON_SCN_TIME" ("TIME_MP") TABLESPACE SYSAUX;
SQL> CREATE UNIQUE INDEX "SYS"."SMON_SCN_TIME_SCN_IDX" ON "SYS"."SMON_SCN_TIME" ("SCN") TABLESPACE SYSAUX;

Execute the analyze table for SMON_SCN_TIME table.

 

SQL> ANALYZE TABLE SMON_SCN_TIME VALIDATE STRUCTURE CASCADE ONLINE;

Table analyzed.

If this problem is seen during database startup and there are lots of corruption, you should set the following parameters in init.ora parameter file.

*.undo_management='MANUAL'
*._allow_resetlogs_corruption=true
*._allow_error_simulation=true

 

Then startup database again.

If database has been start up, then you can remove the above parameters again.

 

The latest solution is startup or restart instance again.
