set newname for指导restore和 duplicate,set newname之后如果跟着switch,就是为了把restore出来的镜像拷贝变为数据文件,switch实际上就是alter database rename file '' to '':
  1. run{
  2. set newname for datafile 5 to '/home/oracle/examplettio.dbf';
  3. restore datafile 5;
  4. delete datafilecopy '/home/oracle/examplettio.dbf';
  5. }
复制代码

set newname语法可以在克隆时与 set db_file_name_convert/set log_file_name_convert互相替换。

关于克隆的backup location的语法:
1. 在源头数据库上做:
  1. --源头把备份优化关掉,或用force语法

  2. run {
  3. allocate channel  c1 device type disk format '/home/oracle/backup/%U';
  4. allocate channel  c2 device type disk format '/home/oracle/backup/%U';
  5. allocate channel  c3 device type disk format '/home/oracle/backup/%U';
  6. allocate channel  c4 device type disk format '/home/oracle/backup/%U';
  7. allocate channel  c5 device type disk format '/home/oracle/backup/%U';
  8. allocate channel  c6 device type disk format '/home/oracle/backup/%U';
  9. allocate channel  c7 device type disk format '/home/oracle/backup/%U';
  10. allocate channel  c8 device type disk format '/home/oracle/backup/%U';
  11. backup database plus archivelog force;
  12. backup spfile;
  13. backup current controlfile;
  14. }
复制代码
把源头库上的/home/oracle/backup/完整scp -rp 到目的地机器相同的位置:
在目的机器上写一个只有一行或两行的init.ora:db_name=...  db_domain=...
db_name和db_doamin必须在目的地机器上做静态注册。
开启克隆命令:
  1. run{
  2. duplicate target database to mydb
  3. backup location '/home/oracle/backup'
  4. nofilenamecheck
  5. skip tablespace  'TBS1','TBS2'
  6. spfile
  7. set
  8. control_files='/u01/app/oracle/oradata/mydb/control01.ctl','/u01/app/oracle/oradata/mydb/control02.ctl','/u01/app/oracle/oradata/mydb/control03.ctl'
  9. set
  10. db_file_name_convert='+DATA/orcl/datafile/example.258.880451611','/u01/app/oracle/oradata/mydb/example01.dbf','+DATA/orcl/datafile/users.259.880451615','/u01/app/oracle/oradata/mydb/users01.dbf','+DATA/orcl/datafile/undotbs1.256.880451607','/u01/app/oracle/oradata/mydb/undotbs01.dbf','+DATA/orcl/datafile/sysaux.257.880451605','/u01/app/oracle/oradata/mydb/sysaux01.dbf','+DATA/orcl/datafile/system.265.880451605','/u01/app/oracle/oradata/mydb/system01.dbf'
  11. set
  12. log_file_name_convert='+DATA/orcl/onlinelog/group_1.270.880453135','/u01/app/oracle/oradata/mydb/redo01a.log','+FRA/orcl/onlinelog/group_1.276.880453137','/u01/app/oracle/oradata/mydb/redo01b.log','+DATA/orcl/onlinelog/group_3.272.880453141','/u01/app/oracle/oradata/mydb/redo03a.log','+FRA/orcl/onlinelog/group_3.274.880453141','/u01/app/oracle/oradata/mydb/redo03b.log','+DATA/orcl/onlinelog/group_2.271.880453137','/u01/app/oracle/oradata/mydb/redo02a.log','+FRA/orcl/onlinelog/group_2.275.880453139','/u01/app/oracle/oradata/mydb/redo02b.log'
  13. set
  14. audit_file_dest='/u01/app/oracle/admin/mydb/adump'
  15. set
  16. db_create_file_dest=''
  17. set
  18. db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'
  19. }

如果做dataguard的主备库的口令文件一定要写ignorecase=y
主库改了4个对应的参数:
  1. SQL> alter system set log_archive_config='dg_config=(PROD1,STDBY)';

  2. System altered.

  3. SQL> alter system set log_archive_dest_1='location=use_db_recovery_file_dest';

  4. System altered.


  5. SQL> alter system set log_archive_dest_2='service=STDBY  valid_for=(online_logfiles, primary_role) db_unique_name=STDBY';

  6. System altered.

  7. SQL> show parameter standby

  13. System altered.
复制代码
  1. SQL> conn / as sysdba
  2. Connected.
  3. SQL> alter database enable force logging;

备库的克隆脚本:
  1. run{
  2. duplicate target database
  3. for standby
  4. from active database
  5. nofilenamecheck
  6. spfile
  7. set
  8. control_files='/u01/app/oracle/oradata/STDBY/control01.ctl','/u01/app/oracle/fast_recovery_area/STDBY/control02.ctl'
  9. set
  10. db_file_name_convert='/u01/app/oracle/oradata/PROD1','/u01/app/oracle/oradata/STDBY'
  11. set
  12. log_file_name_convert='/u01/app/oracle/oradata/PROD1','/u01/app/oracle/oradata/STDBY'
  13. set

  17. set
  18. db_unique_name='STDBY';
  19. }
复制代码
备库RMAN命令:
  1. rman target sys/oracle_4U@PROD1 auxiliary sys/oracle_4U@STDBY cmdfile=STDBY.rcv
复制代码

在备库上执行以下命令:
  1. SQL> alter database  recover managed standby database disconnect from session;
复制代码

关掉日志应用的命令:
  1. SQL> alter database  recover managed standby database  cancel ;

  2. Database altered.

  3. SQL> !ps aux | grep mrp
  4. oracle   18755  0.0  0.0   4732   996 pts/2    S+   02:41   0:00 /bin/bash -c ps aux | grep mrp
