检查REDO日志相关信息并生成HTML文件的脚本
生成HTML格式的文件
内容有：
检查数据库版本、REDO日志组情况，
最近20次日志切换频率检查--日志间的归档时间间隔, 这对查看数据库的IO繁忙时段
统计指定日期当天每小时的归档日志产生量--日期通过手动修改脚本中日期实现
统计最近10天每天的归档日志产生量
脚本如下：
prompt Creating database report.
prompt This script must be run as a user with DBA privileges.
prompt This process can take several minutes to complete.
prompt need Specified date in---------archive log_MB in day
