主要原因是,gc的知识库是通过drop user 方式删除的,而不是通过正常的RepManager dropall 删除,因此sysman_mds模式的相关记录没有清除导致.

解决办法:
   登陆emrep数据库,检查以下结果:
SQL> select comp_name from SCHEMA_VERSION_REGISTRY;
COMP_NAME
--------------------------------------------------------------------------------
Metadata Services


执行以下命令删除即可:
SQL> delete from SCHEMA_VERSION_REGISTRY where COMP_NAME='Metadata Services';
SQL> commit;


再去点gc重试,可以继续.
