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/oraclecd 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
