不装Oracle客户端的情况下配置plsql

1,先到Oracle网站下载Instant Client :
HYPERLINK "http://www.oracle.com/technology/global/cn/software/tech/oci/instantclient/index.html"
http://www.oracle.com/technology/global/cn/software/tech/oci/instantclient/index.html
根据你的操作系统选择不同的Instant Client版本
下载回是一个压缩文件,解压之后的文件夹叫:D:\instantclient_11_2.放在你喜欢的目录即可.例如:D:\instantclient_11_2
2.在D:\instantclient_11_2目录下新建目录network,在network目录下再新建admin目录,在admin目录下新建文件tnsnames.ora,使用文本编辑器打开写入如下内容:
MWDB=

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.58)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = 数据库名)

)

)
3.配置plsql
点击“Tool”－－>Preferences



修改两处Oracle配置，重启plsql即可
