oracle有很多特性在lightdb无法使用，使用该工具可以即时扫描某个在线数据库或本地文件夹中有哪些不兼容特性，-a -x对oracle不兼容特性有所区别，扫描范围可参考后续表格。

0、使用限制

1. 默认扫描存储过程，函数及包
2. 默认仅支持oracle数据库扫描
3. 默认排除系统用户'SYS', 'SYSTEM', 'SYSMAN'

1、环境配置

用户需要下载安装oracle客户端：instantClient-basic-Windows.x64-11.2.0.4.0.zip

  并将其加入path环境变量中，如‘D:\工具\instantclient-basic-windows.x64-11.2.0.4.0\instantclient_11_2’。

2、配置oracle连接字符串

检查并配置./conf/DBconfig.ini文件，必须有 'oracle' 节点，且有 'connectstring' 键值对。

将CheckUnsupportOracle\conf\DBconfig.ini中connectstring的取值替换为你需要的字符串。

OWNER字段：可选，大小写不敏感，用户不存在时会忽略该用户，多用户之间用逗号或者空格分割。

 

3、支持本地文件夹扫描

如果需要支持本地文件扫描，需要将待扫描的文件都放入到同级的files目录下即可，扫描结果参考log文件。

如果该文件夹没有，新建该files目录即可。

右键以管理员身份运行CheckUnsupportOracle.exe

 

 

等待执行结束，新增如下文件：

 

 

也可以从logs目录的文本文件中去查看不兼容扫描结果说明
