Oracle監聽器混亂

Question

作爲Oracle 12c的新手，我在修改memory_target設置的同時搞亂了網絡設置，我很奇怪，但知道它發生了什麼。

到目前爲止，SID = oradb2在主機oracle12c.mydomain.com的1538上很好地收聽。現在它不。我不知道1539港口是如何進入圖片的。我希望你能幫助我。

這裏是我的$ ORACLE_HOME /網絡/管理/ listener.ora文件：

LISTENER1 = 
    (DESCRIPTION_LIST = 
    (DESCRIPTION = 
     (ADDRESS = (PROTOCOL = TCP)(HOST = oracle12c.mydomain.com)(PORT = 1538)) 
    ) 
) 

LISTENER = 
    (DESCRIPTION_LIST = 
    (DESCRIPTION = 
     (ADDRESS = (PROTOCOL = TCP)(HOST = oracle12c.mydomain.com)(PORT = 1539)) 
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) 
    ) 
) 

這裏是我的$ ORACLE_HOME /網絡/管理/ tnsnames.ora文件

ORADB2 = 
    (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle12c.omilia.com)(PORT = 1539)) 
    (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = oradb2)) 
) 
LISTENER_ORADB2 = (ADDRESS = (PROTOCOL = TCP)(HOST = oracle12c.omilia.com)(PORT = 1538)) 
LISTENER_ORADB1 = (ADDRESS = (PROTOCOL = TCP)(HOST = oracle12c.omilia.com)(PORT = 1538)) 

現在聯繫oradb2通過端口1539上的JDBC的SID給了我ORA-12505錯誤，並且端口1538甚至沒有在監聽。

tnsping oradb2給

Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = oracle12c.mydomain.com)(PORT = 1539)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = oradb2))) 
OK (10 msec) 

的/home/oracle/app/oracle/admin/oradb2/scripts/init.ora文件包含行

local_listener=ORADB2 

Answer 1

添加(SID = oradb2)您CONNECT_DATA塊在ORADB2 TNS條目：

監聽器入口應該是這樣的：

ORADB2 = 
    (DESCRIPTION_LIST = 
     (DESCRIPTION = 
     (ADDRESS_LIST = 
      (ADDRESS = 
       (PROTOCOL = TCP) 
       (HOST = oracle12c.mydomain.com) 
       (PORT = 1539) 
      ) 
     ) 
    ) 
     (CONNECT_DATA = 
     (SID = oradb2) 
    ) 
    ) 

然後在TNSNAMES.ORA把這個：

ORADB2 = 
    (DESCRIPTION = 
    (ADDRESS = 
     (PROTOCOL = TCP) 
     (HOST = oracle12c.omilia.com) 
     (PORT = 1539) 
    ) 
    (CONNECT_DATA = 
     (SID = oradb2) 
    ) 
) 

你可以做任何你想在這裏的端口。只要確保您在偵聽器和tnsnames條目中使它相同即可。
