  • linux 6.4平台利用rman迁移oracle 11g r2数据库


    测试环境分别在虚拟机安装A,B主机
    系统:linux 6.4,
    数据库:oracle 11g r2
    A主机:安装oracle 11g r2数据库
    B主机:只安装oracle 11g r2软件

    第一步,运行下面rman命令备份数据库
    run{
    CONFIGURE CONTROLFILE AUTOBACKUP ON;
    CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u01/app/dbback/config_%F';
    allocate channel c1 type disk format '/u01/app/dbback/full_%U';
    backup database tag 'full_gpodb_data' FILESPERSET 10 PLUS ARCHIVELOG FILESPERSET 20 DELETE ALL INPUT;
    release channel c1;
     }


    [root@bogon ~]# su - oracle
    [oracle@bogon ~]$ rman target /

    5> backup database tag 'full_gpodb_data' FILESPERSET 10 PLUS ARCHIVELOG FILESPERSET 20 DELETE ALL INPUT;
    6> release channel c1;
    7>  }

    RMAN>


    第二步,创建pfile参数文件

    [oracle@bogon dbs]$ sqlplus "/as sysdba"

    Connected to:
    Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
    With the Partitioning, OLAP, Data Mining and Real Application Testing options


    SQL> create pfile from spfile;

    File created.

    第三步,利用scp命令将备份文件,pfile参数文件传输到B主机
    备份文件的目标在/u01/app/dbback,首先在B主机创建dbback目录
    [oracle@bogon app]$ mkdir dbback

    传输pfile文件(这这里将/u01/app/oracle/product/11.2.1/db_1/dbs目录下的文件全部传输到了B主机)
    [oracle@bogon dbs]$ scp * 192.168.1.103:/u01/app/oracle/product/11.2.1/db_1/dbs
    The authenticity of host '192.168.1.103 (192.168.1.103)' can't be established.

    传输/u01/app/dbback目录下的备份文件
    [oracle@bogon dbback]$ scp * 192.168.1.102:/u01/app/dbback
    The authenticity of host '192.168.1.102 (192.168.1.102)' can't be established.

    [oracle@bogon dbback]$ cd ~

    第四步,登陆B主机,创建和A主机相对应的文件夹

    我主机的oracle 文件安装在/u01/app/oracle


    [oracle@bogon app]$ cd oracle
    [oracle@bogon oracle]$ ls        ---------------和A主机对应缺少了diag  flash_recovery_area  oradata admin  cfgtoollogs 文件夹
    checkpoints  product
    [oracle@bogon oracle]$
    [oracle@bogon oracle]$ mkdir diag  flash_recovery_area  oradata admin  cfgtoollogs        --------创建文件夹
    [oracle@bogon oracle]$ cd oradata
    [oracle@bogon oradata]$ ls
    [oracle@bogon oradata]$ mkdir db
    [oracle@bogon oradata]$ ls
    db

    [oracle@bogon oracle]$ cd cfgtoollogs
    [oracle@bogon cfgtoollogs]$ ls
    [oracle@bogon cfgtoollogs]$ mkdir dbca  emca  netca
    [oracle@bogon cfgtoollogs]$

    [oracle@bogon admin]$ mkdir db
    [oracle@bogon admin]$ cd db
    [oracle@bogon db]$ ls
    [oracle@bogon db]$ mkdir adump dpdump  pfile
    [oracle@bogon db]$
    [oracle@bogon oracle]$ cd flash_recovery_area
    [oracle@bogon flash_recovery_area]$ ls
    [oracle@bogon flash_recovery_area]$ mkdir db

    [oracle@bogon app]$ pwd
    /u01/app
    [oracle@bogon archiv]$ mkdir archiv              

    第五步,启动B主机数据库到nomount状态
    oracle@bogon ~]$ export ORACLE_SID=db
    [oracle@bogon ~]$
    [oracle@bogon ~]$ sqlplus "/as sysdba"

    第六步,用rman恢复数据库

    [oracle@bogon admin]$ rman target /
