同一主机下Duplicate DB实验（含GI）

发布时间：2020-08-08 16:43:04 来源：ITPUB博客 阅读：145 作者：大鲨鱼o0O 栏目：关系型数据库
说明性文字：
           oracle版本11g        操作系统：oracle linux 5
       Main DB（target DB）  ----->连接------>   Duplicate DB

同一主机下Duplicate DB实验（含GI）
----根据主库创建Duplicate DB的目录
----根据主库的参数文件（pfile）创建Duplicate DB的参数文件（pfile），如果在上述路径没有找到的话在主库创建pfile：create pfile from spfile;  然后再到$ORACLE_HOME/dbs路径下ls就能看到了
----图中的vim /etc/hosts是为了添加IP解析
[root@sink ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 sink localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.10.6 sink
同一主机下Duplicate DB实验（含GI）
-----删除 sink.  的行，那是在sink实例下内容，我们这里是在根据sink库创建test库，所以不能存在sink实例的参数信息
-----修改memory_target的大小，最好和原始值有一定的差距，因为那是一个主机运行的内存，如果不修改就会报错，提示无法打开test库
-----如果有db_unique_name需要删掉这一行，不删的话就是一个库，unique是别名的意思，相当于创建辅助库，在手工TSPITR  和 RMAN TSPITR的时候需要设置db_unique_name，这里新设一个库，所以不需要
-----注意control_files的路径，最好设在一个路径下面好修改，当然也可以多路复用，只不过比较麻烦而已，这部分内容我还掌握的不好，不好班门弄斧，这里就设置同一路径吧
-----  esc 到底行命令模式  :%s/sink/test/g  替换所有sink为test
----- 最后 加入 最下面2个 路径转换（数据文件，redo日志文件），最好去主库看一下asm路径，这是只是参考性的路径，您的实际路径肯定和我的不一样
同一主机下Duplicate DB实验（含GI）
----配置了GI之后listener.ora监听就由GI接管了，所以在grid用户网络配置中配置监听
----在duplicate当中test库是必须是nomunt状态的，所以如果要连接监听，就只能是静态注册，所以在默认监听上给test配置静态注册
----下面的tnsname.ora的信息是我截图多出来了，不用理会
----ORACLE_HOME需要特别注意别写错了，我当时就写错了，然后后面的lsnrctl status的时候看到的状态老是BLOCKED，这里踩了一个大坑，最好在命令行下echo $ORACLE_HOME查看一下实际的路径
同一主机下Duplicate DB实验（含GI）
----来到oralce用户，listener.ora信息是截图多出来的不必理会（图片没处理好，请大家见谅，我也只是小白，一知半解，坚持写博客只是为了激发热情，分享感悟）
----到oracle网络配置路径下，配置tnsname.ora，sink（main DB）test（duplicate DB）
同一主机下Duplicate DB实验（含GI）
---默认的是sink实例
----直接 !sql --->  打开 sink（main DB）
同一主机下Duplicate DB实验（含GI）
----export到test实例
----将test库startup nomount
同一主机下Duplicate DB实验（含GI）
---到grid用户下重新启动listener监听
---发现test连接上了，状态信息显示为UNKNOW表示test走的是刚才配置的静态注册，如果为BLOCKED则表示你配置静态注册存在问题，test没有走静态注册
同一主机下Duplicate DB实验（含GI）
-----开始  main DB （sink） -----连接----->  duplicate DB  （test）
-----提示：error 来自 目标库，target DB 是指 main DB （主库 sink）所以下面重启sink库
同一主机下Duplicate DB实验（含GI）
-----重启target DB
同一主机下Duplicate DB实验（含GI）
----重启之后，正常进入了RMAN环境
----duplicate 开始duplicate target DB 到（to） test 库 
同一主机下Duplicate DB实验（含GI）
----这是duplicate命令的结束截图，如图database opened ....表示克隆完成
同一主机下Duplicate DB实验（含GI）
------重新来到克隆好的test库，做一下简单查询，查看test的信息
同一主机下Duplicate DB实验（含GI）
-----好了，感觉成功了

这是最后一步执行克隆的输出信息，留给下次研究，因为我也不知道Duplicate DB的过程中到底是什么样的过程，这里暂且搁置，下次一定补好
