Oracle 冷备份和冷恢复

阅读说明

1.参数说明?
COLD_BACK_DIR: 冷备份目录
SCRIPT_FILE: 此代码所生成的批处理文件路径及文件名称
LOG_FILE: 备份日志文件存放路径及文件名称
INT_PWD: internal用户的口令
保存生成的sql文件。

2.在实际生产环境中参数根据实际情况而定

3.执行cmd cd 到保存生成sql文件的指定目录

4.sqlplus 用户名/密码@数据库实例 @sql文件名

例: sqlplus?system/123@orcl?@oracleremark.sql

5.如何未创建coolback文件夹,oracleremark.sql将不会自动生成,需要手动创建

6.测试环境实在本机或服务器上。
