[Oracle]Plsql连接Oracle

关于plsql连接的教程有很多，其中最重要的就是D:\oracle\product\10.2.0\db_1\network\ADMIN下的listener和tnsnames两个文件。经过反复修改与测试，终于成功了。

Listener文件:

# listener.ora Network Configuration File: d:\oracle\product\10.2.0\db_1\network\admin\listener.ora

# Generated by Oracle configuration tools.

 SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (GLOBAL_DBANAME = orcl)

      (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)

      (SID_NAME = ticelab)

    )

  )

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

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

    )

  )

Tnsnames文件:

 # tnsnames.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.

TICELAB =

  (DESCRIPTION =

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

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = ticelab)

    )

  )

EXTPROC_CONNECTION_DATA =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

    )

    (CONNECT_DATA =

      (SID = PLSExtProc)

      (PRESENTATION = RO)

    )

  )
