HomeDatabaseMysql Tutorial本地没有装Oracle,PL/SQL远程访问Oracle数据库配置

去Oracle网站下载Instant Client,需要的人留言,给你发网盘链接。然后安装,我是直接安在了PL/SQL的安装目录里面,目录为:C:\p

之前写过一篇关于Oracle数据库远程连接的博客:Oracle数据库——服务端配置远程连接 。

在那篇文章中操作推荐过别人的一篇博客,就是本博客的这个话题。但是最近要用了,于是就翻自己的博客,却发现那个博客已经限制访问了,在网上又找了好久,才找到这个,于是果断自己写一下,以备今后自用以及方便他人。

1、安装PL/SQL,这个过程还是比较容易的,就不再多说了,我的目录为:C:\plsql

2、去Oracle网站下载Instant Client,需要的人留言,,给你发网盘链接。然后安装,我是直接安在了PL/SQL的安装目录里面,目录为:C:\plsql\odac_client。

3、在此目录中新建一个名为tnsnames.ora的文件,打开定入如下内容:

ORCL =

(DESCRIPTION =

(ADDRESS_LIST =

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

)

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

4、添加名为TNS_ADMIN的环境变量,值为tnsnames.ora文件的路径

5、打开PL/SQL,直接点取消,就会进入主界面。选择Tools中的Preference,在里面设置Oracle Home为C:\plsql\odac_client,OCI Library为C:\plsql\odac_client\oci.dll。

6、配置完成后重启PL/SQL。

7、可能会碰到乱码的问题,只需要用下面命令查一下编码:

select userenv('language') from dual;

只需要添加一个环境变量NLS_LANG,值为上面语句查到的结果,就不会有乱码问题了。

最后,个人建议,我用的是有道笔记,对于看到的功能性博客(比如此篇),就收藏到里面,只是单纯的收藏一个地址还是不那么靠谱的,写此篇文章,只为提出一点建议,另自己的学习更加高效。

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.
