1、下载instantclient，我的是WIN7，下载的是instantclient-basiclite-nt-12.1.0.1.0.zip
3、编辑文件内容，注意IP和PROT要用远程ORACLE的# tnsnames.ora Network Configuration Fil髫潋啜缅e: C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora# Generated by Oracle configuration tools.ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.176.110)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) )EXTPROC_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) ) (CONNECT_DATA = (SID = PLSExtProc) (PRESENTATION = RO) ) )
4、设置PLSQL，菜单为Tools\Prefrence
5、重新启动PLSQL，可以远程连接了
