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

目录

  • 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）

db_unique_name			         string	      HISDB
global_names			         boolean	 FALSE
instance_name			         string	     hisdb1（节点1的实例名）
lock_name_space 		         string
log_file_name_convert		     string	     /oradata/dghisdb/onlinelog/, +DATA/hisdb/onlinelog/
processor_group_name		     string
service_names			         string	      HISDB
