解決安裝Oracle本地可以訪問客戶端不能訪問

現象：本地需要修改監聽為localhost --》win+r--》 sqlplus system/123@xxdb 可以登陸，遠程客戶端不能登陸；需要將監聽修改為IP地址，重啟監聽；遠程可以訪問，plsql：192.168.0.111:50000/xxdb,賬號:system密碼123

解決方案：將tnsnames.ora的HOST改為ip，將listener.ora的HOST改為本機計算機名稱。

配置完重啟服務OracleServicexxdb

# tnsnames.ora Network Configuration File: d:\app\orcl\product\12.1.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

xxdb =
  (DESCRIPTION =
    (ADDRESS_LIST =
　　   (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT =1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.111)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = xxdb)
    )
  )

 

listener.ora  配置完重啟監聽

# listener.ora Network Configuration File: d:\app\orcl\product\12.1.0\dbhome_1\network\admin\listener.ora

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = d:\app\orcl\product\12.1.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:d:\app\orcl\product\12.1.0\dbhome_1\bin\oraclr12.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =

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

windows servers 2012控制面板--》系統和安全--》Windows防火牆--》高級設置--》左側 選擇 入站規則--》右側 新建入站規則

規則類型選端口--》TCP 特定端口填1521--》下一步下一步默認，然后填上名稱。
