今天在手工配置Oracle 11g的EM时总是报如下错误：
WARNING: ORA-00001: unique constraint (SYSMAN.PARAMETERS_PRIMARY_KEY) violated
ORA-06512: at "SYSMAN.EMD_LOADER", line 4986
ORA-06512: at line 1
以Metalink上也没有找到解决办法，以下是我的解决过程：
1、 数据库版本
SQL> select * from v$version;
BANNER

2、 配置EM时的步骤
[oracle@Core-Nbu-Rollback ~]$ emca -config dbcontrol db -repos recreate
