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。

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('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','SYS_p550a');

PL/sql procedure successfully completed

sql>commit;

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
