Log File Problems in tomcat
hi
Using tomcat 5.5.27 on Linux machine .
Whenever i am deleting log files(catalina,localhost etc log files) from
tomcat_home\logs path.These are not auto genrating .Everytime i need to
restart tomcat to get thise files i dont want this.Any solution to this?
Same problem with my application logs i am using SLF4J and logback to
genrate logs.once application log files removed i need to restart tomcat to
regenrate.
Problem with Linux only window not alow to delete log files in use.please
update if anything i can configure to overcome this

That is how unixes work. See "man unlink" e.g. here [1] or the POSIX
spec. The actual deletion happens only when all applications that are
reading or writing the file have closed it.
[1] http://linux.die.net/man/2/unlink
You can truncate the file though, without deleting it.
I think the following will work:
cat /dev/null > yourfile

Thanks for reply. I was also thinking in that way but after all i need
same user to delete(for eg old log deletion or manual deletion) also.So want
to avoid restarting tomcat just to create new logs.
Looking for some solution at tomcat level so my tomcat always run even if
current log files are deleted it should able to genrate new log file
automatically.

You could get someone to configure Tomcat to run under an account you
don't have permission to access, this would prevent anyone from doing
something so silly as to delete the log files while Tomcat is using them.

Yes: stop deleting the log files.

You should configure SLF4J to perform log file rolling for you, instead
of trying to (evidently) do it yourself.

Step 1: stop logging things to stdout/stderr
Step 2: configure Tomcat's loggers to roll on whatever schedule you like
http://tomcat.apache.org/tomcat-7.0-doc/logging.html
Step 3: configure your application loggers to roll on whatever schedule
you like
