前言

昨天安装一套 EMCC13.5，安装过程中 VNC 卡死导致安装失败，清理目录后重新执行安装，结果安装过程中报错了：

报错信息：The referenced database doesn't contain a valid management Repository

应该是 OMS 数据库在前一次安装过程中已经创建了用户以及一些对象，导致 OMS 数据库不干净了，一般建议重建 OMS 数据库，但是时间比较久，今天介绍一下另一种解决这个问题的方法。

解决方案

删掉 OMS 数据库中已创建的 EMCC 相关用户：

SQL> DROP USER SYSMAN CASCADE;
DROP USER SYSMAN_MDS CASCADE;
DROP USER SYSMAN_RO CASCADE;
DROP USER SYSMAN_STB CASCADE;

删掉 sysman 用户相关的同义词：

DECLARE
  CURSOR l_syn_csr IS
    SELECT 'DROP ' || CASE owner
             WHEN 'PUBLIC' THEN
              'PUBLIC SYNONYM '
             ELSE
              'SYNONYM ' || owner || '.'
           END || synonym_name AS cmd
      FROM dba_synonyms
     WHERE table_owner IN ('SYSMAN',
                           'SYSMAN_MDS',
                           'MGMT_VIEW',
                           'SYSMAN_BIP',
                           'SYSMAN_APM',
                           'BIP',
                           'SYSMAN_OPSS',
                           'SYSMAN_RO');
BEGIN
  FOR l_syn_rec IN l_syn_csr LOOP
    BEGIN
      EXECUTE IMMEDIATE l_syn_rec.cmd;
    EXCEPTION
      WHEN OTHERS THEN
        dbms_output.put_line('===> ' || l_syn_rec.cmd);
        dbms_output.put_line(sqlerrm);
    END;
  END LOOP;
END;
/

删除用户 MGMT_VIEW：

DROP USER mgmt_view CASCADE;

删除 OMS 相关的表空间：

SQL> DROP TABLESPACE mgmt_ecm_depot_ts INCLUDING CONTENTS AND DATAFILES CASCADE CONSTRAINTS;
DROP TABLESPACE mgmt_tablespace INCLUDING CONTENTS AND DATAFILES CASCADE CONSTRAINTS;
DROP TABLESPACE mgmt_ad4j_ts INCLUDING CONTENTS AND DATAFILES CASCADE CONSTRAINTS;

清理注册信息：

SQL> DELETE
FROM
schema_version_registry
WHERE
(comp_name,owner) IN (
('Authorization Policy Manager','SYSMAN_APM'),
('Metadata Services','SYSMAN_MDS'),
('Oracle Platform Security Services','SYSMAN_OPSS')
);

commit;

检查是否还有以下用户存在：

SQL> select USERNAME, ACCOUNT_STATUS
  from dba_users
 where username in ('CLOUD_ENGINE_USER',
                    'CLOUD_SWLIB_USER',
                    'MGMT_VIEW',
                    'SYSMAN_TYPES',
                    'SYSMAN_OPSS',
                    'SYSMAN_STB',
                    'SYSMAN_RO');

如果存在以上用户，则删除：

SQL> drop user CLOUD_ENGINE_USER cascade;
drop user CLOUD_SWLIB_USER cascade;
drop user SYSMAN_TYPES cascade;
drop user SYSMAN122140_OPSS cascade;

重新点击下一步进行 OMS 安装，不再报错：

无需重建 OMS 数据库也可以继续安装，问题解决。
