单实例数据库迁移到rac环境(三)

在前两节中，分别介绍了使用expdp/impdp迁移单实例数据库到rac环境的方法，其中包括使用表空间传输的方式，但如果在用户数量多，或者表空间数量多，又或者函数，过程，包等代码对象多的条件下，使用前两种方式迁移未免麻烦且费时，因而在本节中将简要的介绍下使用rman备份的异机恢复来实现迁移单实例数据库到rac环境，这种方式美中不足的地方是数据库需要以open resetlogs方式打开，意味着对数据库做不完全恢复，可能会丢失少量的数据！

环境介绍：
数据库的版本均为10.2.0.5，数据库字符集编码为utf8
操作系统的版本单实例数据库(源库)为rhel5.4 64 bit 数据库名：orcl.yang.com 实例名：orcl
rac(目标数据库)为ceontos4.8 64bit

一：目标数据库准备工作，rman备份的异机恢复要求数据库名要一致，因而需要先删掉原有的racdb数据库和数据文件

[oracle@rac1 ~]$ srvctl stop database -d racdb -o immediate [oracle@rac1 ~]$ srvctl remove database -d racdb Remove the database racdb? (y/[n]) y [oracle@rac1 ~]$ crs_stat -t -v Name           Type           R/RA   F/FT   Target    State     Host        ---------------------------------------------------------------------- ora....SM1.asm application    0/5    0/0    ONLINE    ONLINE    rac1        ora....C1.lsnr application    0/5    0/0    ONLINE    ONLINE    rac1        ora.rac1.gsd   application    0/5    0/0    ONLINE    ONLINE    rac1        ora.rac1.ons   application    0/3    0/0    ONLINE    ONLINE    rac1        ora.rac1.vip   application    0/0    0/0    ONLINE    ONLINE    rac1        ora....SM2.asm application    0/5    0/0    ONLINE    ONLINE    rac2        ora....C2.lsnr application    0/5    0/0    ONLINE    ONLINE    rac2        ora.rac2.gsd   application    0/5    0/0    ONLINE    ONLINE    rac2        ora.rac2.ons   application    0/3    0/0    ONLINE    ONLINE    rac2        ora.rac2.vip   application    0/0    0/0    ONLINE    ONLINE    rac2 节点2上同样需要修改/etc/oratab文件 [root@rac1 ~]# tail -n 1 /etc/oratab +ASM1:/u01/app/oracle/product/10.2.0/db_1:N   [oracle@rac1 ~]$ export ORACLE_SID=+ASM1 [oracle@rac1 ~]$ asmcmd ASMCMD> rm -rf +DATA/RACDB ASMCMD> rm -rf +FRA/RACDB [oracle@rac1 ~]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Tue Jan 3 12:43:13 2012 Copyright (c) 1982, 2010, Oracle.  All Rights Reserved.

二：源库上建一个测试表，由spfile生成pfile

SQL> show parameter name; NAME                                 TYPE        VALUE ------------------------------------ ----------- ------------------------------ db_file_name_convert                 string db_name                              string      orcl db_unique_name                       string      orcl global_names                         boolean     FALSE instance_name                        string      orcl lock_name_space                      string log_file_name_convert                string service_names                        string      orcl.yang.com SQL> create table test1.migrate(a varchar2(20)); Table created. SQL> insert into test1.migrate a values ('successful'); 1 row created. SQL> commit; Commit complete. SQL> create pfile='/home/oracle/rman_bak/initorcl.ora' from spfile; File created.

SQL> select file_id,file_name,tablespace_name from dba_temp_files order by 1;    FILE_ID FILE_NAME                                          TABLESPACE_NAME ---------- -------------------------------------------------- ---------------          1 /u01/app/oracle/oradata/orcl/temp01.dbf            TEMP SQL> select file_name,tablespace_name from dba_temp_files; FILE_NAME                                          TABLESPACE_NAME -------------------------------------------------- -------------------- /u01/app/oracle/oradata/orcl/temp01.dbf            TEMP

三：在源库上使用rman进行全库备份，并将备份复制到目标数据库上

[oracle@server49 ~]$ rman target / Recovery Manager: Release 10.2.0.5.0 - Production on Tue Jan 3 12:10:06 2012 Copyright (c) 1982, 2007, Oracle.  All rights reserved. connected to target database: ORCL (DBID=1299224612) RMAN> backup incremental level 0 2> format '/home/oracle/rman_bak/orcl_%U' 3> database plus archivelog 4> delete all input; RMAN> backup current controlfile format '/home/oracle/rman_bak/migrate.ctl'; RMAN> list backup of database summary; List of Backups =============== Key     TY LV S Device Type Completion Time #Pieces #Copies Compressed Tag ------- -- -- - ----------- --------------- ------- ------- ---------- --- 2       B  0  A DISK        03-JAN-12       1       1       NO         TAG20120103T121503 [oracle@server49 ~]$ scp -rp /home/oracle/rman_bak/ rac1:/home/oracle/

四：在目标数据库上执行恢复
4.1 修改初始化参数文件如下

[oracle@rac1 ~]$ cat /home/oracle/rman_bak/initorcl.ora *.__db_cache_size=79691776 *.__java_pool_size=4194304 *.__large_pool_size=4194304 *.__shared_pool_size=109051904 *.__streams_pool_size=8388608 orcl1.instance_name='orcl1' orcl2.instance_name='orcl2' orcl1.instance_number=1 orcl2.instance_number=2 *.cluster_database=true *.cluster_database_instances=2 orcl1.thread=1 *.compatible='10.2.0.5.0' *.control_files='+DATA/orcl/controlfile/control01.ctl','+FRA/orcl/controlfile/control02.ctl' *.audit_file_dest='/u01/app/oracle/admin/orcl/adump' *.background_dump_dest='/u01/app/oracle/admin/orcl/bdump' *.core_dump_dest='/u01/app/oracle/admin/orcl/cdump' *.user_dump_dest='/u01/app/oracle/admin/orcl/udump' *.db_block_size=8192 *.db_domain='yang.com' *.db_file_multiblock_read_count=16 *.db_name='orcl' *.db_recovery_file_dest='+FRA' *.db_recovery_file_dest_size=21474836480 *.log_archive_dest_1='LOCATION=+FRA/orcl/archivelog' *.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)' *.job_queue_processes=10 *.log_archive_format='%t_%s_%r.arc' *.open_cursors=300 *.pga_aggregate_target=71303168 *.processes=150 *.remote_login_passwordfile='EXCLUSIVE' *.sga_target=213909504 *.undo_management='AUTO' orcl1.undo_tablespace='UNDOTBS1' orcl2.undo_tablespace='UNDOTBS2' 备注：需要格外注意的是，这个时候不能加orcl2.thread=2参数，否则后面无法将数据库启动到mount状态

4.2 创建相关的目录，两个节点上都应该存在相应的目录和密码文件

[oracle@rac1 ~]$ mkdir -p  /u01/app/oracle/admin/orcl/{adump,bdump,cdump,udump} [oracle@rac1 ~]$ cd $ORACLE_HOME/dbs [oracle@rac1 dbs]$ echo 'spfile=+DATA/ORCL/PARAMETERFILE/spfileorcl.ora' > initorcl1.ora [oracle@rac1 dbs]$ orapwd file=orapworcl1 password=123456 [oracle@rac2 ~]$ cd $ORACLE_HOME/dbs [oracle@rac2 dbs]$ echo 'spfile=+DATA/ORCL/PARAMETERFILE/spfileorcl.ora' > initorcl2.ora [oracle@rac2 dbs]$ orapwd file=orapworcl1 password=123456

4.3 利用pfile生成spfile，并保存在ASM实例上，ASM磁盘组中需要存在相应的目录，否则将报错！

[oracle@rac1 ~]$ export ORACLE_SID=orcl1 [oracle@rac1 ~]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Tue Jan 3 13:00:10 2012 Copyright (c) 1982, 2010, Oracle.  All Rights Reserved.

ASMCMD> pwd +DATA/ORCL/PARAMETERFILE ASMCMD> ls spfileorcl.ora SQL> shutdown abort; ORACLE instance shut down.

4.4 将节点1数据库启动到nomount状态，恢复控制文件，重新将数据库启动到mount状态

[oracle@rac1 ~]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Tue Jan 3 13:09:48 2012 Copyright (c) 1982, 2010, Oracle.  All Rights Reserved.
