EM资料库重建手动删除资料库

由于原来的数据库已经被删除，再重做oem时需要用到监听，此时直接重做报如下错误：

[Oracle@localhost ~]$ emca -repos recreate

提示找不到监听，可是监听确实存在

索性直接创建新的oem

CONFIG: ORA-20001: SYSMAN already exists..

ORA-06512: at line 17

观察生成的日志发现sysman用户已经存在，这是由于用老的em资料库配置数据库导致的，删除该用户

oracle.sysman.assistants.util.sqlEngine.SQLFatalErrorException: ORA-20001: SYSMAN already exists..

ORA-06512: at line 17

at oracle.sysman.assistants.util.sqlEngine.SQLPlusEngine.executeScript(SQLPlusEngine.java:265)

再次执行仍然报错，还没完了。。。

CONFIG: ORA-01921: role name 'MGMT_USER' conflicts with another user or role name

oracle.sysman.assistants.util.sqlEngine.SQLFatalErrorException: ORA-01921: role name 'MGMT_USER' conflicts with another user or role name

登入数据库，这下彻底删除与em有关的用户信息

select grantee, granted_role from dba_role_privs where granted_role = 'MGMT_USER';
drop role mgmt_user;
drop user sysman cascade;
drop user mgmt_view cascade;

SET HEADING OFF;
spool a.sql
SELECT 'DROP PUBLIC SYNONYM ' || SYNONYM_NAME || ';'
FROM ALL_SYNONYMS
WHERE OWNER = 'PUBLIC' AND TABLE_OWNER ='SYSMAN';
spool off
SET HEADING ON;
@a.sql

再次创建资料库就行了
