本文主要是介绍Oracle10g Logical DataGuard 详细搭建过程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
logical standby是在physical standby基础上搭建
Oracle10g Physical DataGuard 详细搭建过程
--停止standby上的日志应用
SQL> alter database recover managed standby database cancel;
Database altered.
--修改主库log_archive_dest_3参数,当切换为备库时在线日志归档路径
SQL> alter system set log_archive_dest_3='LOCATION=/u01/app/oracle/oradata/dbserver/arch valid_for=(standby_logfiles,standby_role) db_unique_name=dbserver';
System altered.
SQL> alter system set log_archive_dest_state_3=enable;
System altered.
--主库执行,alert.log显示Logminer Bld: Done
SQL> execute dbms_logstdby.build;
PL/SQL procedure successfully completed.
--修改备库log_archive_dest_3参数,备库在线日志归档路径
SQL> alter system set log_archive_dest_3='LOCATION=/u01/app/oracle/oradata/standby/arch valid_for=(standby_logfiles,standby_role) db_unique_name=standby';
System altered.
SQL> alter system set log_archive_dest_state_3=enable;
System altered.
--如果备库没有临时表空间需要创建
--在standby端将物理备库转为逻辑备库,最后一个standby是逻辑备库名称
