linux下连接oracle数据库出错：ORA-12514

修改listener.ora 文件：

加：

  (SID_DESC =
      (GLOBAL_DBNAME = hanmi)
      (ORACLE_HOME = /u01/oracle/product/10.2.0/db_1)
      (SID_NAME = hanmi)
    )

修改后为：

 #SID_LIST_LISTENER =
#  (SID_LIST =
#    (SID_DESC =
#      (SID_NAME = PLSExtProc)
#      (ORACLE_HOME = /u01/oracle/product/10.2.0/db_1)
#      (PROGRAM = extproc)
#    )
#
#  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.20.20)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

 

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = hanmi)
      (ORACLE_HOME = /u01/oracle/product/10.2.0/db_1)
      (SID_NAME = hanmi)
    )
  )
