Cloud Control资料数据库的选择

按照规划可以选择单实例或者集群。
OMR可以通过DBCA新建或者EM模板

如果采用DBCA新建实例，可以会在安装12c Cloud Control时遭遇Check the existence of public synonyms， Remove the public synonyms错误，解决方法如下：

1.删除资料库用户：

1. drop user SYSMAN cascade;
2. drop user SYSMAN_MDS cascade;
3. drop user MGMT_VIEW cascade;
4. drop user SYSMAN_RO cascade;
5. drop user SYSMAN_OPSS cascade;
6. drop user SYSMAN_APM cascade;
7. drop user SYSMAN_BIP;
8. drop user CLOUD_SWLIB_USER cascade;
9. drop user CLOUD_ENGINE_USER cascade;
10. drop role MGMT_USER;

2.删除同义词：

1. select ‘drop ‘|| decode(owner,‘PUBLIC‘,owner||‘ synonym ‘||synonym_name, ‘ synonym ‘||owner||‘.‘||synonym_name) ||‘;‘ from dba_synonyms where table_owner in (‘SYSMAN‘, ‘SYSMAN_MDS‘, ‘MGMT_VIEW‘, ‘SYSMAN_BIPLATFORM‘, ‘SYSMAN_APM‘, ‘SYSMAN_OPSS‘, ‘SYSMAN_RO‘) ;

删除之后用如下语句查询一下：

1. select owner,synonym_name from dba_synonyms where table_owner in (‘SYSMAN‘, ‘SYSMAN_MDS‘,‘MGMT_VIEW‘,‘SYSMAN_BIP‘,‘SYSMAN_APM‘,‘SYSMAN_OPSS‘,‘SYSMAN_RO‘) ;

3.删除表空间;

1. select ‘drop tablespace ‘||tablespace_name||‘ including contents and datafiles;‘ from dba_tablespaces where tablespace_name like ‘MGMT%‘;

4.删除对象：

1. delete from SCHEMA_VERSION_REGISTRY where COMP_NAME=‘Metadata Services‘;
2. delete from SCHEMA_VERSION_REGISTRY where COMP_NAME=‘Authorization Policy Manager‘;
3. delete from SCHEMA_VERSION_REGISTRY where COMP_NAME=‘Oracle Platform Security Services‘;
4. commit;

执行以上步骤之后，安装顺利完成！
