- 从 Oracle 集群到单节点环境（详细记录一次数据迁移过程）之一：生产环境与目标服务器详情
- 一、操作系统环境
- 二、Oracle 数据库基本信息（节点1）
- 三、数据文件信息
- 四、日志文件信息
- 五、Oracle 数据库总数据量
- 六、数据文件总大小
用户有一个双节点 Oracle 集群，由于工作需要，需要对生产库中的数据进行测试。基于数据安全考虑，测试方提出把生产库中的数据导出，然后导入一个单机测试环境进行数据测试。
生产数据环境为 Oracle11g 双节点集群，服务器操作系统为 Centos7.3，目标服务器为单节点服务器，服务器操作系统为 Centos7.5，详细情况如下：
一、操作系统环境
# 1、生产服务器操作系统环境（节点1）
[root@his01 bak0921]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
# 2、目标服务器操作系统环境
[root@node1 oradata]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
二、Oracle 数据库基本信息（节点1）
