  • 配置静态监听解决ORA-12514错误的案例(转)

    今天做Linux下DG配置的时候,遇到一个现象,tnsname.ora文件配置都正常,tnsping也正常,监听也正常,但是仍然报ORA-12514错误:

    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 =
          (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))
        )
      )
     
    注意,加上的内容中,SID_NAME,即instance_name,而GLOBAL_DBNAME,即tnsnames.ora中的SERVICE_NAME,由于tnsnames.ora中的SERVICE_NAME都是prd,因此这里的两个名字是一样的,不会有什么影响,把修改好的文件替换掉原文件,再重新加载监听文件

    原来dest_id=2的那个远程归档路径的ORA-12514的问题解决了,此时归档日志就可以通过网路远程传输到备库相应的归档路径中了,再执行redo apply也不会有任何问题了。
     
    总结:
     
    这个案例是由于主备库都采用了同一个实例名产生的问题,当我们只配置一个默认的动态监听,会发现主库无法监听到远程备库的相应服务,通过静态监听手动添加上与实例名对应的服务,才能解决这个问题。使用静态监听的另一个好处是,当Oracle数据库实例还没有启动的时候,就会先把对应的服务和实例名,通过静态配置的监听文件给启动起来,而不是等启动实例后由pmon进程再去启动,这样速度更快。不用再等待若干秒,我们的客户端就可以通过静态监听立即脸上数据库服务器了,也就是说,可以不依赖服务器进程,完成监听的工作。
