虚拟专用恢复目录

一、创建恢复目录
1、建表空间
 create tablespace rc_data datafile '/u01/app/oracle/oradata/ocp/rc_data.dbf' size 50m;


2、建用户
 create user rc_ocp identified by rc_ocp default tablespace rc_data quota unlimited on rc_data;


3、授权
 grant connect,resource,recovery_catalog_owner to rc_ocp;


4、创建目录
 rman catalog rc_ocp/rc_ocp


 create catalog;
 
 5、注册
 rman target sys/oracle@ocp catalog rc_ocp/rc_ocp@ocp


 register database;


 6、查incarnation
  list incarnation;


 二、虚拟专用目录：
   1.先建表空间，用户，授权
  sys@OCP>create user v_user1 identified by v_user1 default tablespace tp1 temporary tablespace temp quota unlimited on tp1;
   
  sys@OCP> grant recovery_catalog_owner to v_user1;
   
  2.用基本恢复目录登录给v_user1用户授权
   [oracle@ocm ~]$ rman catalog rc_ocp/rc_ocp
    grant catalog for database ocp to v_user1;
    grant catalog for database ocm to v_user1;


  3.用虚拟用户登录，建恢复目录
   [oracle@ocm ~]$ rman catalog v_user1/v_user1
    create virtual catalog;
     
     list incarnation


  4.sqlplus v_user1/v_user1
   select * from RC_BACKUP_DATAFILE;


三、备份脚本


      create script datafile_5{
      backup datafile 5;
     }


    run{execute script full_db;}


    rman target sys/oracle@oca catalog rc_admin/rc_admin@oca script datafile_4


     list script names;


     print script datafile_4;


     replace script datafile_4{
       backup format='/backup/rman/full_%U'
       database;
      }


四、常用操作
    delete script full_db;
    resync catalog;
    unregister database;
    upgrade catalog;
    drop catalog;
