My catalina.out file has grown to an enormous size. What is the best way to empty it?... If I delete and replace it with an empty catalina.out file, will I need to restart Tomcat?
Inorder to delete it or rename and save it.. first you have to stop server. Then u can delete it or rename it and save(if you want to go through that logs again). When you restart server you will have new catalina.out.
