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

TNS Ping Utility for Linux: Version 11.2.0.4.0 - Production on 08-MAY-2016 09:13:42

Used parameter files:

Used TNSNAMES adapter to resolve the alias

Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.112)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = test_m2)))

OK (0 msec)

[oracle@azure_test_dbm1_3_111 admin]$

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：

[oracle@azure_test_dbm1_3_112 admin]$ rlwrap sqlplus / as sysdba

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

SQL*Plus: Release 11.2.0.4.0 Production on Sun May 8 09:19:48 2016

ERROR:

ORA-12514: TNS:listener does not currently know of service requested in connect

descriptor

Enter user-name:

# 备库sqlplus登录报错

[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 09:18:39 2016

ERROR:

ORA-12514: TNS:listener does not currently know of service requested in connect

descriptor

Enter user-name:

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

SQL*Plus: Release 11.2.0.4.0 Production on Sun May 8 09:34:51 2016

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

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。
