DATAGURAD主库
系统：solaris 10
数据库：10.2.0.4   RAC ASM

备库：
物理备库
其注册在11G的监听上。
注：该备库主机上有一套11GRAC还有10G的备库。

以下是详细处理过程：
1、重做日志不能同步至备库，ALERT日志中报如下错：
Tue May  6 09:34:50 2014
Errors in file /oracle/admin/dbrac/bdump/dbrac1_lns1_23898.trc:
ORA-12170: TNS:Connect timeout occurred
LNS: Failed to archive log 32 thread 1 sequence 206745 (12170)
Tue May  6 09:38:55 2014
Error 12170 received logging on to the standby
Tue May  6 09:38:55 2014
Errors in file /oracle/admin/dbrac/bdump/dbrac1_arc3_8899.trc:
ORA-12170: TNS:Connect timeout occurred
FAL[server, ARC3]: Error 12170 creating remote archivelog file 'dbrac_standby'
FAL[server, ARC3]: FAL archive failed, see trace file.


2、通过排查，备库IP能通，TNS配置正常，由于备库的监听HANG住，
a、查看备库监听状态发现监听HANG住
bash-3.00$ lsnrctl status

bash-3.00$ 

b、将监听进程予以kill重启后，重做日志能正常同步至备库。
bash-3.00$ ps -ef |grep lsnr

备库监听恢复正常，检查主库ALERT日志，主库重做日志传输正常，详细如下:
