  • RMAN迁移数据库(不改变文件目录)


    1、目标库创建相应目录
    mkdir -p /u01/app/oracle/oradata/orcl
    mkdir -p /u01/app/oracle/fast_recovery_area/ORCL
    mkdir -p /u01/app/oracle/admin/orcl/{a,dp}dump

    2、目标库创建密码文件
    orapwd file=orapworcl password=oracle

    3、原库备份
    RMAN> backup as compressed backupset database plus archivelog;

    4、将原库备份传输到目标库
    在目标库创建目录存放原库传输过来的原库备份
    mkdir –p /home/oracle/bak
    mkdir –p /home/oracle/autobak
    利用scp工具传输,具体不详细介绍。

    5、修改dbid

    [oracle@orcl ~]$ rman target /
    Recovery Manager: Release 11.2.0.3.0 - Production on Mon Nov 5 11:19:38 2018

    Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.

    connected to target database: (not started)
    RMAN> set dbid 238796283
    executing command: SET DBID

    6、恢复参数文件
    RMAN> startup nomount

    startup failed: ORA-01078: failure in processing system parameters
    LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/db_1/dbs/initorcl.ora'

    starting Oracle instance without parameter file for retrieval of spfile
    Oracle instance started

    Total System Global Area 159019008 bytes

    Fixed Size 1343612 bytes
    Variable Size 75501444 bytes
    Database Buffers 79691776 bytes
    Redo Buffers 2482176 bytes

    RMAN> restore spfile to pfile '/u01/app/oracle/product/11.2.0/db_1/dbs/initorcl.ora' from '/home/oracle/autobak/o1_mf_s_991416863_fy03o039_.bkp';

    Starting restore at 05-NOV-18
    using target database control file instead of recovery catalog
    allocated channel: ORA_DISK_1
    channel ORA_DISK_1: SID=19 device type=DISK

    channel ORA_DISK_1: restoring spfile from AUTOBACKUP /home/oracle/autobak/o1_mf_s_991416863_fy03o039_.bkp
    channel ORA_DISK_1: SPFILE restore from AUTOBACKUP complete
    Finished restore at 05-NOV-18

    RMAN> exit


    Recovery Manager complete.

    7、创建spfile

    [oracle@fz-orcl autobak]$ sqlplus / as sysdba

    SQL*Plus: Release 11.2.0.3.0 Production on Mon Nov 5 18:28:15 2018

    SYS@orcl>select status from v$instance;

    STATUS

    SYS@orcl>exit
    Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production
    With the Partitioning, OLAP, Data Mining and Real Application Testing options

    8、恢复控制文件,并将数据库开启到mount状态

    [oracle@fz-orcl autobak]$ rman target /

    Recovery Manager: Release 11.2.0.3.0 - Production on Mon Nov 5 18:29:57 2018

    Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.

    connected to target database: ORCL (not mounted)

    RMAN> restore controlfile from '/home/oracle/autobak/o1_mf_s_991416863_fy03o039_.bkp';

    Starting restore at 05-NOV-18
    using target database control file instead of recovery catalog
    allocated channel: ORA_DISK_1
    channel ORA_DISK_1: SID=19 device type=DISK

    channel ORA_DISK_1: restoring control file
    channel ORA_DISK_1: restore complete, elapsed time: 00:00:01
    output file name=/u01/app/oracle/oradata/orcl/control01.ctl

    Finished restore at 05-NOV-18

    RMAN> alter database mount;

    database mounted
    released channel: ORA_DISK_1

    9、注册备份文件

    RMAN> catalog start with '/home/oracle/bak';

    Starting implicit crosscheck backup at 05-NOV-18
    allocated channel: ORA_DISK_1
    channel ORA_DISK_1: SID=19 device type=DISK
    allocated channel: ORA_DISK_2
    channel ORA_DISK_2: SID=20 device type=DISK

    10、恢复数据库

    RMAN> restore database;

    Starting restore at 05-NOV-18
    using channel ORA_DISK_1
    using channel ORA_DISK_2
