How to truncate alert log file ??

[SANJAY_G]

Hi,

My alert log file has grown very big and I want to truncate it and start a new alert log file. How can I do this on a unix system while database is up.
Appreciate all the help.

Just
mv alert.log alert.log.save (or what ever). The Oracle server will then create another alert.log and start writing to it.

I have a cron job that goes out and renames all my alert.log files to alert.log.<today's date> at midnight. I then re-touch the alert.log file. This allows me to run a find -mtime and delete a specified number of days of alert.log files.
