DATAGUARD主庫重做日誌不能同步至備庫 alert日中報ORA-12170故障處理
DATAGURAD主庫
系統：solaris 10
資料庫：10.2.0.4 RAC ASM
備庫：
物理備庫
其註冊在11G的監聽上。
注：該備庫主機上有一套11GRAC還有10G的備庫。
以下是詳細處理過程：
1、重做日誌不能同步至備庫，ALERT日誌中報如下錯：
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、透過排查，備庫IP能通，TNS配置正常，由於備庫的監聽HANG住，
a、檢視備庫監聽狀態發現監聽HANG住
bash-3.00$ lsnrctl status

bash-3.00$
b、將監聽程式予以kill重啟後，重做日誌能正常同步至備庫。
