tnsping测试下来也都是通的，这就比较奇怪了，但是ORA-12514错误很明显是指监听方面的问题，导致服务名无法解析，由于主备库采用的是同一个实例名，因此两边的instance_name用的都是prd，乍一看好像很正常，但是解析确实出现了问题，那么怎么办呢？
之前仅仅只是给服务器配置了一个动态监听，内容如下：
--主库监听listener.ora # listener.ora Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora # Generated by Oracle configuration tools.
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1) (PROGRAM = extproc) ) )
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = prd)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0)) ) )
--主库监听listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora # Generated by Oracle configuration tools.
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1) (PROGRAM = extproc) ) )
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = std)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0)) ) )
可以看到，区别仅仅是主机名不同而已，一个是prd，另一个是std，静态监听并未配置，即SID_LIST_LISTENER这一项里面的栏目，那么现在为主备库都配置一个监听。静态监听可以用netmgr配置，这里为了方便，不再进入图形界面执行该命令，而是直接通过修改listener.ora文件来达到目的，其效果是一样的，在原来的listener.ora文件中的SID_LIST_LISTENER中添加如下内容（红色部分）：
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = prd) (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1) (SID_NAME = prd) ) (SID_DESC =
