ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

 

ORA-12514: TNS

环境：
主库 ：rac2(192.168.0.162)
备库：memberstor-host(192.168.0.182)
两个库已经在broker下建立了dataguard,而且一切正常当中
但是当我尝试用rac2
操作：
dgmgrl>connect sys/******@192.168.0.182
时,就出现了：
Unable to connect to database
ORA-12514: TNS: listener does not currently know of  service requested in connect descriptor


listener.log07-FEB-2012 15:53:14 * (CONNECT_DATA=(SERVICE_NAME=192.168.0.182)(CID=(PROGRAM=dgmgrl@rac2)(HOST=rac2)(USER=oracle))) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.0.182)(PORT=18267)) * establish * 192.168.0.182 * 12514
TNS-12514: TNS:listener does not currently know of service requested in connect descriptor



监听端口都是默认的1521

solve:

connect sys/******@192.168.0.182

easy connection 的连接串形式  ip:port/Servicename

监听日志
listener.log07-FEB-2012 15:53:14 * (CONNECT_DATA=(SERVICE_NAME=192.168.0.182)(CID=(PROGRAM=dgmgrl@rac2)(HOST=rac2)(USER=oracle))) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.0.182)(PORT=18267)) * establish * 192.168.0.182 * 12514


SERVICE_NAME=192.168.0.182  ， 这里因为你的连接串写的 有问题所以把 ip当成servicename处理了， 肯定会出现ORA-12514错误

若要使用easy connection， 修改连接字符串

=================

做个记录，继续了解

 

 

终于知道什么原因了：

1.查看rac1与rac2的tnsnames.ora

rac1：

ORCLRAC2 =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = rac2)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = orcl)

    )

  )

EXTPROC_CONNECTION_DATA =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

    )

    (CONNECT_DATA =

      (SID = PLSExtProc)

      (PRESENTATION = RO)

    )

  )

 

rac2：

ORCLRAC1 =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = orcl)

    )

  )

 

EXTPROC_CONNECTION_DATA =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

    )

    (CONNECT_DATA =

      (SID = PLSExtProc)

      (PRESENTATION = RO)

    )

 

红黑处就是我们要连接的名～～

如下：

rac1$ dgmgrl sys/********@orclrac2

问题解决！！

 

在这里再提一下：

有时候我们不得不修改listener.ora文件，当出现 ORA-12541之类的错误，原因网上都说了一大堆，个人总结是要因为定义的监听未被database注册，我们就可以使用到全局定义:global_nam,在listener.ora文件里面添加：

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (SID_NAME = orclstanl)

      (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)

      (GLOBAL_DBNAME = orclstanl_DGMGRL)

      (Server_name = orclstanl)

    )

    (SID_DESC =

      (SID_NAME = orcl)

      (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)

      (GLOBAL_DBNAME = orcl)

    )

 

 

  )

=================================================

其实这里还是有些不是很明白的，当创建了dataguard后，listener.ora后被添加了

    (SID_DESC =

      (SID_NAME = orclstanl)

      (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)

      (GLOBAL_DBNAME = orclstanl_DGMGRL)

      (Server_name = orclstanl)

    )

里面也有个global_name...到底这个这么回事暂时不很清楚，尝试

$dgmgrl sys/*****@orclstanl,

结果还是TNS-12541~~~

留个脚印，以后再详细查看，不得不感叹oracle是个大家伙
