oracle 10 dataguard rman duplicate

说明：oracle 11g dataguard 可以直接用rman duplicate全盘复制，10g的rman duplicate 就just so so 了。
这里把步骤理一下：
主库生成口令文件，改下归档路径，生成pfile：

SQL> alter system set log_archive_format='%t_%s_%r.arc' scope=spfile;

SQL> alter system set log_archive_dest_2='service=standby lgwr valid_for=(online_logfiles,primary_role) db_unique_name=standby';

SQL> alter system set log_archive_dest_1='location=/data/arch1' scope=spfile;

SQL> create pfile='/home/oracle/whty.ora' from spfile;

orapwd file=orapwwhty ignorecase=y password=oracle

备份数据库和控制文件

RMAN> backup database format '/home/oracle/%u';

SQL>alter database create standby controlfile as '/home/oracle/control.ctl';

增加standby redo log

ALTER DATABASE ADD STANDBY LOGFILE 'srl1.f' SIZE 52428800;

ALTER DATABASE ADD STANDBY LOGFILE 'srl2.f' SIZE 52428800;

ALTER DATABASE ADD STANDBY LOGFILE 'srl3.f' SIZE 52428800;

ALTER DATABASE ADD STANDBY LOGFILE 'srl4.f' SIZE 52428800;

启动duplicate
rman target / auxiliary sys/"oracle"@standby
duplicate target database for standby nofilename check;
备库：

修改pfile,如果打开好审计，注意关闭audit

*.audit_file_dest='/opt/admin/standby/adump'

*.audit_trail=NONE

*.background_dump_dest='/opt/admin/standby/bdump'

*.compatible='10.2.0.5.0'

*.control_files='/data/standby/control01.ctl'

*.core_dump_dest='/opt/admin/standby/cdump'

*.db_block_size=8192

*.db_domain=''

*.db_file_multiblock_read_count=16

*.db_name='whty'

*.db_unique_name='standby'

*.fal_client='standby'

*.fal_server='whty'

*.db_recovery_file_dest='/data/flash_recovery_area'

*.db_recovery_file_dest_size=4294967296

*.dispatchers='(PROTOCOL=TCP) (SERVICE=whtyXDB)'

*.job_queue_processes=10

*.log_archive_dest_1='location=/data/arch1'

*.log_archive_dest_2='location=/data/arch2 valid_for=(standby_logfiles,standby_role) db_unique_name=standby'

*.log_archive_format='%t_%s_%r.arc'

*.open_cursors=300

*.pga_aggregate_target=67108864

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=203423744

*.undo_management='AUTO'

*.undo_tablespace='UNDOTBS1'

*.user_dump_dest='/opt/admin/standby/udump'
