In linux/solaris, I can specify

And get a logfile named as such
/my/logs/sourcecode-gc-1008-0938.log
with the last time of startup as past of the log filename
But if I try to do something similar in Windows
-Xloggc:c:\my\logs\sourcecode-gc-${NOW}.log
I get a logfile named
c:\my\logs\sourcecode-gc-${NOW}.log
with the variable text as past of the log filename
Does tomcat on Windows not support variables in the GC filename?
I've tried a dozen different combinations
$DATE // ${%DATE%} // $[%DATE%] // $(%DATE%)
${DATE} // $[DATE] // $(DATE) // $DATE // %DATE // %NOW%
`%DATE%` // '%DATE%' // `cmd /c now /t` // 'cmd /c now /t'
%Y // %YYYY
and several other iterations
but the logfilename contains the variable that I was hoping would be
replaced with a timestamp.
and I can't seem to find a solid reference for Windows GC log filenames.
Hi.
1) That's not really a Tomcat question, it's a Java JVM question.
So the question "Does tomcat on Windows not support variables in the GC filename?" is
mis-directed. The "-Xloggc" is not a Tomcat parameter, it is a JVM parameter, interpreted
by the JVM which runs Tomcat. Get the difference ?
2) Under Linux, where is the "NOW" variable set ? (probably in a Tomcat startup shell
script, right ?)
3) How do you start (the JVM which runs) Tomcat under Windows ?
(If it is started as a Windows Service, it doesn't really have a Linux-like shell. It -
or rather the "service wrapper" (which runs the JVM which runs Tomcat) - takes its
parameters from the Windows Registry, not the command-line. No shell = no shell variables
= no "NOW").
