Oracel数据库 listener.ora和tnsnames.ora配置

Posted 2020-09-20 亲爱的阿道君

oracel服务经常会出现各种监听问题，很多情况是 listener.ora和tnsnames.ora 的配置有问题  D:\\app\\Administrator\\product\\11.2.0\\dbhome_1 oracel安装路径径参考自己的

listener.ora配置   

# listener.ora Network Configuration File: D:\\app\\Administrator\\product\\11.2.0\\dbhome_1\\network\\admin\\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\\app\\Administrator\\product\\11.2.0\\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\\app\\Administrator\\product\\11.2.0\\dbhome_1\\bin\\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\\app\\Administrator

tnsnames.ora配置

# tnsnames.ora Network Configuration File: D:\\app\\Administrator\\product\\11.2.0\\dbhome_1\\network\\admin\\tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


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

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

重启listener和orcl服务
