[Oracle][Data Guard]Oracle11g Active Data Guard#2实战
11g建立过程大多和10g相同,利用rman duplicate快速建立physics standby是最佳选择，最大差异就是rman command
(前面建立过程可参考Oracle 10g DG第五章Create physical standby db by SQL+快速复制数据库-rman Duplicate小弟就不在写了)
连线至auxiliary database
执行 rman command(差异部分小弟用红色highlight起来)
RUN {
allocate channel c1 type disk;
ALLOCATE AUXILIARY CHANNEL ax1 DEVICE TYPE DISK;ALLOCATE AUXILIARY CHANNEL ax2 DEVICE TYPE DISK;ALLOCATE AUXILIARY CHANNEL ax3 DEVICE TYPE DISK;ALLOCATE AUXILIARY CHANNEL ax4 DEVICE TYPE DISK;
duplicate target database for standby from active database dorecover;}
建立完成后测试同步功能
开启standby db redo apply
Check current sequence
alter system switch logfile;
switchlog后primary和standby同步成功。
下篇小弟将实测physics standby db open readonly状态下可否open redo apply services
