ORACLE如何清除OEM下的历史警告信息

ORACLE10G如何清除OEM下的历史警告信息
 
问题描述：OEM的HOME页面可以显示ORACLE的报警信息，但报警事件清除后该信息不会自动清除。随着时间的增长，信息量逐渐加大，解决方法是手工予以清除。

严重性	目标名称	目标类型	类别	名称	消息	预警触发时间
	Sample	Cluster Database	Tablespaces Full	Tablespace Free Space (MB)	Tablespace [TEMP] only has [0 megabytes ] free space	2008-12-8 10:24:36
	Sample1	Database Instance	Waits by Wait Class	Database Time Spent Waiting (%)	事件类 "Cluster" 的度量 "Database Time Spent Waiting (%)" 位于 100	2008-12-10 0:45:07
	Sample1	Database Instance	Global Cache Statistics	Global Cache Average Current Block Request Time (centi-seconds)	度量 "Global Cache Average Current Get Time" 位于 .95	2008-12-10 0:45:07
	Sample2	Database Instance	Waits by Wait Class	Database Time Spent Waiting (%)	事件类 "Other" 的度量 "Database Time Spent Waiting (%)" 位于 64.10273	2008-12-10 0:44:42
	Sample	Cluster Database	Invalid Objects by Schema	Owner's Invalid Object Count	WLSN 方案中存在 24 个无效对象。	2008-12-9 9:31:08

 
 
解决步骤：
1、  用下面的语句组装生成清除警告信息的脚本

select 'exec em_severity.delete_current_severity(''' || target_guid ||''',''' || metric_guid || ''',''' || key_value || ''');' from sysman.MGMT_CURRENT_SEVERITY
 
'EXECEM_SEVERITY.DELETE_CURRENT_SEVERITY('''||TARGET_GUID||''','''||METRIC_GUID|
--------------------------------------------------------------------------------
exec em_severity.delete_current_severity('01BA0082955EC11184C650961DC16313','86821B5F0CE858D6E4A7F7390E88B73C',' ');
 
exec em_severity.delete_current_severity('6DB37247A7C97ED3ED8BAA58B26CA47A','C733EA1CFA96377F492528E305462C9D','Other');
 
exec em_severity.delete_current_severity('6DB37247A7C97ED3ED8BAA58B26CA47A','D6438569B496BC9205481E8A70F92F1E','SYS_p550b');
 
exec em_severity.delete_current_severity('6F95E72E3550CDA14CA88B085851A52C','2448AD7604076832840D5B18E562B9C2','ADCPHC');
 
3 rows selected.
 
 
2、以sysman用户login SQLPLUS 后执行上一步生成的脚本（注意是sysman用户，用sys不行）

Connected to Oracle Database 10g Enterprise Edition Release 10.2.0.3.0
Connected as SYSMAN
 

SQL> exec em_severity.delete_current_severity('FC17617395481D6B11DED9FE7CA63BF8','D6438569B496BC9205481E8A70F92F1E','SYS_p550a');
 

PL/SQL procedure successfully completed
 

SQL>
 
可能出现的问题：
ORA-06550: line 1, column 7:
PLS-00201: identifier 'EM_SEVERITY.DELETE_CURRENT_SEVERITY' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
问题原因及处理：可能你用sys登录执行了脚本，必须以sysman登录执行
Oracle中用户的默认密码
system/manager
sys/change_on_install
oem中：
sysman/oem_temp
