说明:在DataGuard的搭建中,运行rman恢复的时候报错ORA-12528的错误; 配置数据库的监听为静态参数步骤:在ORACLE_HOME/network

说明:在DataGuard的搭建中,运行rman恢复的时候报错ORA-12528的错误; 

脚本如下:RMAN>  connect auxiliary sys/Oracle@SCMPRD02 

解决步骤: 

1、检查监听是否启动,脚本:tnsping SCMPRD02 

 方法一:配置数据库的监听为静态参数步骤:在ORACLE_HOME/network/admin 下面检查是否有listener.ora参数文件,,如果没有的话运行netca创建数据库的监听,配置完成的监听文件如下: 

 

LISTENER = 

  (DESCRIPTION_LIST = 

    (DESCRIPTION = 

      (ADDRESS = (PROTOCOL = TCP)(HOST = SCMPRDDB02)(PORT = 1521)) 

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) 

    ) 

  ) 

   

ADR_BASE_LISTENER = /u01/app/oracle
 

方法二:修改tnsnames.ora文件 

 

SCMPRD02 = 
    (DESCRIPTION =
    (ADDRESS =
        (PROTOCOL = TCP)(HOST = WELL)(PORT = 1521))   
          (CONNECT_DATA =     
          (SERVER = DEDICATED)      (
          SERVICE_NAME = SCMPRD02)     
            (UR = A)  //增加该备注// 
              )
                  )
 

总结:ORA-12528: TNS:listener: all appropriate instances are blocking new connections 

Cause:All instances supporting the service requested by the client reported that they were blocking the new connections. This condition may be temporary, such as at instance startup.Action:Attempt the connection again. If error persists, then contact the administrator to check the status of the instances. 

因为我们复制数据库只是在nomount下打开,而数据库并没有mount,在11g下所有的监听都是动态监听,而只有在数据库mount以后,PMON进程起来以后,才能动态注册。所以对辅助数据库没有办法注册,只能被锁住。 

所以修改数据库的监听为静态监听,或者增加(UR=A)即可解决问题;
