OMS配置不成功，重新安裝時，報以下錯誤：
配置階段期間, 安裝程序將無法在指定的數據庫中創建 SYSMAN_MDS 方案。指定的數據庫已配置了管理資料檔案庫。請指定其他數據庫詳細資料, 或在 Oracle Management Service 的 Oracle 主目錄中通過運行以下命令來刪除 SYSMAN_MDS 方案:
<ORACLE_HOME>/sysman/admin/emdrep/bin/RepManager <databaseHost> <ListenerPort> <SID/ServiceName> -action dropall -dbUser <DBUser> -dbPassword <DB Password> -dbRole <DB User Role> -reposName <Repository Name> -reposPassword <reposPassword> -mwHome <MW HOME> -mwOraHome <MW ORA HOME> -oracleHome <ORACLE_HOME>
Solution:
按照提示進行以下操作：
1、進入<ORACLE_HOME>/sysman/admin/emdrep/bin目錄
2、設置ORACLE_HOME和相應的ORACLE_SID
D:\app\orcl\product\11.2.0\dbhome_1\sysman\admin\emdrep\bin>set ORACLE_HOME=D:\app\orcl\product\11.2.0\dbhome_1
D:\app\orcl\product\11.2.0\dbhome_1\sysman\admin\emdrep\bin>set ORACLE_SID=orcl
3、運行命令：
emdrep\bin>RepManager.bat xxx.xxx.x.x 1521 orcl -action drop
然後按照提示輸入相應的信息，可成功刪除sysman方案
