1 ， dataguard 搭建好后，归档日志传输不过去 去查看master库上面的日志 tail –f /data/oracle/diag/rdbms/test_m1/powerdes/trace/alert_powerdes.log，显示信息如下： Sun May 08 00:34:17 2016 Error 1034 received logging on to the standby PING[ARC
1，dataguard搭建好后，归档日志传输不过去
去查看master库上面的日志
tail –f /data/oracle/diag/rdbms/test_m1/powerdes/trace/alert_powerdes.log，显示信息如下：
Sun May 08 00:34:17 2016
Error 1034 received logging on to the standby
PING[ARC2]: Heartbeat failed to connect to standby 'test_m2'. Error is1034.
2，tnsping earch_m2是通的

[oracle@azure_test_dbm1_3_111 admin]$ tnsping test_m3

3，去standby备库上，Check检查下service_name，看到service_names确实是test_m2
看起来service_name也没用错，如下所示：

4，在master库、standby库，通过sqlplus登录报错
|
# 主库登录sqlplus报错 [oracle@azure_test_dbm1_3_111 admin]$ sqlplus sys/testsys@test_m2 as sysdba

都报错：ORA-12514:TNS:listener does not currently know of service requested in connect descriptor，这个问题一般就涉及到的是tnsnames.ora里面的service_name没有写对了。
5，替换service_name，问题解决
回忆这个备库的搭建过程，我刚建库dbca的时候，设置的service_name是powerdes，我在配置dataguard的时候，修改了参数文件initpowerdes.ora，有在里面新设置*.db_unique_name=test_m2，再次create spfile frompfile;然后以新的参数文件启动数据库后，看到service_names变成了test_m2了，而我就在tnsnames.ora里面设置了新的service_names名字test_m2，这个新的test_m2没有生效结果报错ORA-12514了。
因此，我要将没有生效的test_m2换成原来的powerdes，需要换的地方有2个，一个是listener.ora，一个是tnsnames.ora，主库master库和备库standby库都要修改如下所示：
|
#主库master库修改1个文件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) ) )
#备库standby库需要修改2个文件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，然后重启lsnrctl监听服务，再在备库使用sqlplus登录test_m2，登录成功：
|
[oracle@azure_test_dbm1_3_112 admin]$ sqlplus sys/testsys@test_m2 as sysdba

再去看主库master库的后台alert日志，就会发现已经有开始传输归档日志的记录了：

PS：这里问题比较奇怪，我上次这里service_name需要修改成新的参数文件里面的test_m2才能归档日志传输到备库standby上面，但是这次确需要保持原来的service_name。看来这里面还有别的奥妙所在。需要去探索清楚了。
