不安装ORACLE使用PLSQL连接

1.安装PLSQL

2.下载oracle instance client，由于我的PLSQL的版本是12.1，只能下载64位版本，老版本一律使用32位

3.在oracle instance client建NETWORK\ADMIN文件夹，配置

ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

4.在PLSQL首选项制定oracle instance client路径和oci.dll路径

5.重启PLSQL输入用户名密码，bingo!!!
