DG备库之间互传日志文件的问题

深圳－刀

Windows 2008 + Oracle 10.2.0.4
1主库带2个逻辑备库的DG，其中A备库与主库的网络出现问题，但与B备库的网络正常，要如何设置才能让A备库从B备库中取日志？
目前设置参数如下：

主库：
DB_NAME=usaserver
DB_UNIQUE_NAME=usaserver
LOG_ARCHIVE_CONFIG='DG_CONFIG=(usaserver,usaserver2,usaserver3)'
LOG_ARCHIVE_DEST_1 = 'LOCATION=D:\oracle\product\10.2.0\oradata\archive\arc\

LOG_ARCHIVE_DEST_2='SERVICE=usaserver2 LGWR ASYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)   DB_UNIQUE_NAME=usaserver2'
LOG_ARCHIVE_DEST_3= 'LOCATION=D:\oracle\product\10.2.0\oradata\archive\std\ VALID_FOR=(STANDBY_LOGFILES,STANDBY_ROLE)  DB_UNIQUE_NAME=usaserver'
LOG_ARCHIVE_DEST_4='SERVICE=usaserver3 LGWR ASYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)   DB_UNIQUE_NAME=usaserver3 reopen=600'

刚重启A备库，相关日志如附件。
RSF、ARCH进程的trace文件在备库重启后无相关trace产生。

请将 A备库的 alert.log 和 RSF、ARCH进程的trace文件压缩打包后上传
