oracle小知识点16-诊断事件diagnostic events
诊断事件按作用大概可分为四种:
1.Dump diagnostic information on request立即转储诊断信息,可以是File headers (control file, redo log files, data files),System state dumps,Process state dumps.
它的event name是固定的immediate,trace name是具体转储内容.
立即转储一般使用alter session set events 'immediate trace name level '或者oradebug dump 或者sys.dbms_system.set_ev(sid,serial#,65535,,'').
2.Dump diagnostic information when an error occurs根据指定的错误号触发转储信息.
它的event name是错误号Error#,trace name是固定的errorstack.
错误触发转储一般使用参数文件event = " trace name errorstack level "或者alter session set events ' trace name errorstack level '或者oradebug event trace name errorstack level
3.Change database behavior改变数据库运行行为.
它的event name是事件号Event#,trace name是固定的context.
改变数据库运行行为一般使用参数文件event = " trace name context forever,level "或者alter system set event =" trace name context forever,level " scope=spfile
4.Produce trace diagnostics as the database runs产生数据库运行的诊断信息.
它的event name是事件号Event#,trace name是固定的context.
产生数据库运行的诊断信息一般使用参数文件event = " trace name context forever,level "或者alter session/system set event =" trace name context forever,level "
设定诊断事件的方法也可分为四种:
1.The event initialization parameter在pfile初始化参数文件中设定诊断事件.
在参数文件中设定诊断事件,如果要设定多个事件,可以用多个event,event之间要连续(若不连续,只会最后一个event生效),例如:
event = "10015 trace name context forever"
event = "10046 trace name context forever, level 4"
也可以用一个event,用:隔开,例如:
event = "10015 trace name context forever:10046 trace name context forever, level 4"
2.The ALTER {SESSION|SYSTEM} SET EVENTS command通过alter session/system设定诊断事件.
alter system设定的诊断事件是会写到spfile上的.若要取消可以通过alter system reset event scope=spfile.
3.The sys.dbms_system.set_ev(…) procedure通过dbms_system包设定诊断事件.
sys.dbms_system.set_ev格式execute sys.dbms_system.set_ev(sid,serial#,event,level,action),例如:
execute sys.dbms_system.set_ev(8, 219, 10046, 12, '');
4.The ORADEBUG utility通过oradebug命令设定诊断事件.
oradebug命令功能强大,以下是命令help

when an attempt was made to open the standby database.

Set this event to the appropriate level for log writer debugging.
10469, 00000, "error creating control file backup, no checkpoint"
*Cause: The control file being backed up did not
contain a valid control file checkpoint.
Therefore the control file could not be backed up,
as such a backup would not be usable later for recovery.
A common cause for this situation is that you executed
CREATE CONTROLFILE, which mounts the database,
but not ALTER DATABASE OPEN, to open the database.
The latter operation generates a valid control file checkpoint.
*Action: Open the database with ALTER DATABASE OPEN ...,
which results in a valid control file checkpoint.

scenario will be detected and the database will be crashed in a
recoverable state.
level 1: Generate error when linking buffer
level 2: Generate error when unlinking buffer
10484, 00000, "Enable test move operation"
Enable this event to test datafile move operation

10543, 00000, "Standby Block Media Recovery (bmr) and split brain testing event"
Set this event in order to test the situation where standby bmr
does not have the necessary redo to recover a block or the situation
where a split brain occurs during instancecrash recovery.
10544, 00000, "Inject standby autobmr failures"
Set this event to inject block failures that will trigger standby autobmr.
10545, 00000, "Print standby autobmr messages in alert log"
Set this event to print standby autobmr messages in alert log.
10546, 00000, "Cannot perform block media recovery; standby database does not have requisite redo."
*Cause: An attempt was made to perform block media recovery on the standby
database when the necessary redo was not available.
*Action: Wait until the necessary redo is available and reattempt block
media recovery.
10547, 00000, "Cannot perform block media recovery; standby database is not caught up with primary."
*Cause: An attempt was made to perform block media recovery on the standby
database up to scn %s, which is greater than the highest scn of %s
yet applied at the standby.
*Action: Recover the standby up to scn %s and reattempt block media
recovery.
10548, 00000, "Cannot perform block media recovery on a read-only plugged-in datafile."
*Cause: An attempt was made to perform block media recovery on a read-only
plugged-in datafile.
*Action: Convert the plugged-in datafile to readwrite and reattempt block
media recovery.
10549, 00000, "Cannot perform block media recovery using a read-only plugged-in backup datafile."
*Cause: An attempt was made to perform block media recovery using a backup
of a read-only plugged-in datafile.

10551, 00000, "Internal testing for ORA-1551 error handling"
10552 -10589 reserved for recoverable mediastandby recovery
10553, 00000, "Incompatible UNTIL CONSISTENT clause"
*Cause: RECOVER UNTIL CONSISTENT required database-level recovery with
a backup control file.
*Action: Omit the UNTIL CONSISTENT clause and retry recovery.
10554, 00000, "Media recovery failed to bring datafile %s to a consistent point"

to the specified datafile.
*Action: Restore a backup of the datafile.
10555, 00000, "Disable redo dumping"
10558, 00000, "Disable unkeep marker handling for ADG"

*Action: Investigate why the error occurred and how important is the data
block. Media and standby database recovery usually can continue
if user allows recovery to corrupt this data block.
10563, 00000, "Test recovery had to corrupt data block (file# %s, block# %s) in order to proceed"
*Cause: Test recovery completed.

*Action: See associated error message.
10565, 00000, "Another test recovery session is active"
*Cause: There can only be one test recovery session at any time.
Another test recovery session is active.
*Action: Wait till the other test recovery session completes.

*Cause: Test recovery tests redo in memory. It can no longer proceed
because it has consumed all the memory it can use.
*Action: No action is needed. Test recovery has ended successfully.
See other messages on error stack for a summary result
of the test recovery.
10567, 00000, "Redo is inconsistent with data block (file# %s, block# %s, file offset is %s bytes)"
*Cause: There are two possible causes of this error: (1) A write issued
by Oracle was lost by the underlying OS or storage system.
(2) an Oracle internal error.

*Cause: There were not enough memory to restore recovered datafiles
to consistent state
*Action: This error is just a warning: You may not be able to open the
database with resetlogs immediately after this error. However,
you may continue mediastandby recovery, and that may make the

*Cause: See alert file or other errors on the stack for a cause of the
problem.

1.Dump diagnostic information on request立即转储诊断信息,可以是File headers (control file, redo log files, data files),System state dumps,Process state dumps.
它的event name是固定的immediate,trace name是具体转储内容
立即转储一般使用alter session set events 'immediate trace name
2.Dump diagnostic information when an error occurs根据指定的错误号触发转储信息.
它的event name是错误号Error#,trace name是固定的errorstack.
错误触发转储一般使用参数文件event = "
3.Change database behavior改变数据库运行行为.
它的event name是事件号Event#,trace name是固定的context.
改变数据库运行行为一般使用参数文件event = "
4.Produce trace diagnostics as the database runs产生数据库运行的诊断信息.
它的event name是事件号Event#,trace name是固定的context.
产生数据库运行的诊断信息一般使用参数文件event = "
设定诊断事件的方法也可分为四种:
1.The event initialization parameter在pfile初始化参数文件中设定诊断事件.
在参数文件中设定诊断事件,如果要设定多个事件,可以用多个event,event之间要连续(若不连续,只会最后一个event生效),例如:
event = "10015 trace name context forever"
event = "10046 trace name context forever, level 4"
也可以用一个event,用:隔开,例如:
event = "10015 trace name context forever:10046 trace name context forever, level 4"
2.The ALTER {SESSION|SYSTEM} SET EVENTS command通过alter session/system设定诊断事件.
alter system设定的诊断事件是会写到spfile上的.若要取消可以通过alter system reset event scope=spfile.
3.The sys.dbms_system.set_ev(…) procedure通过dbms_system包设定诊断事件.
sys.dbms_system.set_ev格式execute sys.dbms_system.set_ev(sid,serial#,event,level,action),例如:
execute sys.dbms_system.set_ev(8, 219, 10046, 12, '');
4.The ORADEBUG utility通过oradebug命令设定诊断事件.

10469, 00000, "error creating control file backup, no checkpoint"
*Cause: The control file being backed up did not
contain a valid control file checkpoint.
Therefore the control file could not be backed up,
as such a backup would not be usable later for recovery.
A common cause for this situation is that you executed
CREATE CONTROLFILE, which mounts the database,
