PL/SQL连接配置

在Oracle安装目录oracle\product\10.2.0\db_2\NETWORK\ADMIN下修改一下三个文件：

listener.ora，sqlnet.ora，tnsnames.ora

listener.ora：

# listener.ora Network Configuration File: D:\developer\oracle\product\10.2.\db_2\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\developer\oracle\product\10.2.\db_2)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = PC_random)(PORT = ))
    )
  )
#系统自带，不需改变

sqlnet.ora：

# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.

SQLNET.AUTHENTICATION_SERVICES = (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES) 

tnsnames.ora：

test0903 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.107)(PORT = ))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )
test1106_localhost=
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = ))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
 )
