Shell Programming and Scripting

Note also that we're talking about more data being generated in 5 minutes than can be mailed. If there is data in your log file, it is mailed to you and the log file is cleared in 5 minutes or less.

How much data are you logging every 5 minutes? How big of a mail message can you send?

Thanks Don and peasant , its rare scenario for big log file generation , for example ,

if one record is failed in database there will be 10 lines in the log file , some times 100000 records also will be failed, that time the log file will have
100000 * 10 lines.

In this case if the mail body is have any restriction to hold 100000*10 lines then there will be a problem. please suggest . we can use tivoli tool also to trigger the mail.
