1 ， dataguard 搭建好后，歸檔日志傳輸不過去 去查看master庫上面的日志 tail –f /data/oracle/diag/rdbms/test_m1/powerdes/trace/alert_powerdes.log，顯示信息如下： Sun May 08 00:34:17 2016 Error 1034 received logging on to the standby PING[ARC
去查看master庫上面的日志
tail –f /data/oracle/diag/rdbms/test_m1/powerdes/trace/alert_powerdes.log，顯示信息如下：

看起來service_name也沒用錯，如下所示：

都報錯：ORA-12514:TNS:listener does not currently know of service requested in connect descriptor，這個問題一般就涉及到的是tnsnames.ora里面的service_name沒有寫對了。
回憶這個備庫的搭建過程，我剛建庫dbca的時候，設置的service_name是powerdes，我在配置dataguard的時候，修改了參數文件initpowerdes.ora，有在里面新設置*.db_unique_name=test_m2，再次create spfile frompfile;然后以新的參數文件啟動數據庫后，看到service_names變成了test_m2了，而我就在tnsnames.ora里面設置了新的service_names名字test_m2，這個新的test_m2沒有生效結果報錯ORA-12514了。
因此，我要將沒有生效的test_m2換成原來的powerdes，需要換的地方有2個，一個是listener.ora，一個是tnsnames.ora，主庫master庫和備庫standby庫都要修改如下所示：
#主庫master庫修改1個文件tnsnames.ora # tnsnames.ora文件 [oracle@azure_test_dbm1_3_111 admin]$ vim tnsnames.ora test_m2 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.112)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = powerdes) ) ) #備庫standby庫需要修改2個文件listener.ora、tnsnames.ora # listener.ora文件 [oracle@azure_test_dbm1_3_112 admin]$ vim listener.ora SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/dbhome_1) (PROGRAM = extproc) ) (SID_DESC = (SID_NAME = powerdes) (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/dbhome_1) ) ) ADR_BASE_LISTENER = /oracle/app/oracle # tnsnames.ora文件 [oracle@azure_test_dbm1_3_112 admin]$ vim tnsnames.ora test_m2 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.112)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = powerdes) ) ) |
修改完配置后，然后重啟lsnrctl監聽服務，再在備庫使用sqlplus登錄test_m2，登錄成功：
[oracle@azure_test_dbm1_3_112 admin]$ sqlplus sys/testsys@test_m2 as sysdba SQL*Plus: Release 11.2.0.4.0 Production on Sun May 8 09:34:51 2016 Copyright (c) 1982, 2013, Oracle. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options SQL> |
再去看主庫master庫的后臺alert日志，就會發現已經有開始傳輸歸檔日志的記錄了：

PS：這里問題比較奇怪，我上次這里service_name需要修改成新的參數文件里面的test_m2才能歸檔日志傳輸到備庫standby上面，但是這次確需要保持原來的service_name。看來這里面還有別的奧妙所在。需要去探索清楚了。
