Oracle RMAN克隆数据库（同主机）

Oracle RMAN克隆数据库（同主机）

介绍

通过使用数据库备份，DBA 可以在同一服务器或其它服务器上建立副本数据库。

这个副本数据库可以和主数据库有相同的名称（拷贝）或与主数据库名称不同（克隆）。

ORACLE 在数据库拷贝和数据库克隆之间唯一不同的是拷贝的数据库不能更改名称。

克隆数据库

创建目录

[oracle@hfzcdb91:/home/oracle]$mkdir /oradata/hfzctest

[oracle@hfzcdb91:/home/oracle]$mkdir -p /oracle/app/oracle/admin/hfzctest/adump

创建pfile文件

[oracle@hfzcdb91:/home/oracle]$cd $ORACLE_HOME

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/dbs]$sqlplus / as sysdba

SYS@hfzcdb> create pfile from spfile;

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/dbs]$mv inithfzcdb.ora inithfzctest.ora

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/dbs]$vi inithfzctest.ora

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/dbs]$cat inithfzctest.ora

*.audit_file_dest='/oracle/app/oracle/admin/hfzctest/adump'  #修改
*.audit_trail='db'
*.compatible='19.0.0'
*.control_files='/oradata/hfzctest/control01.ctl','/oradata/hfzctest/control02.ctl'# 修改  #修改Restore Controlfile
*.db_block_size=16384
*.db_name='hfzctest'    #修改
*.db_recovery_file_dest_size=107374182400
*.db_recovery_file_dest='/archive'
*.diagnostic_dest='/oracle/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=hfzctestXDB)'  #修改
*.nls_language='AMERICAN'
*.nls_territory='AMERICA'
*.open_cursors=300
*.pga_aggregate_target=500m
*.processes=300
*.remote_login_passwordfile='EXCLUSIVE'
*.sga_target=1800m
*.undo_tablespace='UNDOTBS1'
*.db_file_name_convert=('/oradata/hfzcdb/','/oradata/hfzctest/')  #修改
*.log_file_name_convert=('/oradata/hfzcdb/','/oradata/hfzctest/')  #修改【转换的路径】

创建密码文件

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/dbs]$cp orapwhfzcdb orapwhfzctest

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/dbs]$export ORACLE_SID =hfzctest

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/dbs]$sqlplus “/as sysdba”

启动数据库到nomount

[root@hfzcdb91 ~]# su - oracle

修改listener.ora

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/network/admin/samples]$vi listener.ora

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/network/admin]$vi listener.ora

使用rman克隆数据

[oracle@hfzcdb91:/oracle/app/oracle/product/19c/db_1/network/admin]$rman target sys/oracle@hfzcdb auxiliary sys/oracle@hfzctest 【同时连接两个库】
