10g中的EM相对比较简单，如果新建由于种种原因失败，重新创建的时候，很可能sysman用户没有删除，还存在一些role和public synonym....最后通过select *from dba_synonyms where synonym_name like 'MGM%' 来查看关联的MGM相关的public synonym,发现竟然有差不多300多个...public synonym，这些public synonym是无法通过drop user sysman cascade来删除的，只能指定删除。...select 'DROP '||OWNER||' SYNONYM '||SYNONYM_NAME||';' from dba_synonyms where TABLE_owner='SYSMAN';...发现是将近20个这样的public synonym 再次清理，就顺顺利利完成了EM的安装。
