Subject RE: Tomcat - Win2k service - GC output
Date Thu, 15 Jul 2004 19:39:07 GMT
Hi,

I searched the entire system for .gc files, but couldn't find any.  Now the
question is, where is Tomcat outputting the gc log?

Thanks
-Manoj Pooleery.

Greetings.

OK, well I believe that the output from the  -verbose:gc flag in 1.3 will
write to a .gc file in your [windows]\system32 dirctory - although I am not
certain about this.

DO a system whide search for a .gc file on your server - the output does not
go to the normal log output file(s).

Carl

Hi,

Thank you for the quick response. I'm using jdk 1.3.1_05 and hence I cannot
use -Xloggc option.

Thanks
-Manoj Pooleery.

Hi.

If you are using JSDK 1.4.x use the following VM flag:

-Xloggc:normal.gc

This will create and write GC log entries to the following location on your
windows server:

[WINDOWS_SYSTEM_DIR]\system32\normal.gc

Regards,

Carl

Subject: Tomcat - Win2k service - GC output

Hi,

I have set up Tomcat 4.1.27 as a service on a Win2k machine using the
following script -

tomcat -install "Apache Tomcat" "%JAVA_HOME%\jre\bin\server\jvm.dll"
-verbose:gc -Djava.class.path="%CATALINA_HOME%\bin\bootstrap.jar"
-Djava.endorsed.dir="%CATALINA_HOME%\common\endorsed"
-Dsun.io.useCanonCaches=false -Dcatalina.home="%CATALINA_HOME%" -start
org.apache.catalina.startup.BootstrapService -params start -stop
org.apache.catalina.startup.BootstrapService -params stop -out
"%CATALINA_HOME%\logs\stderr.log"

I wanted to see the GC ouput, so, I added the -verbose:gc flag.  When I see
the registry, I can see this has gone in as a JVM option.  But in the log
file, I cannot see any GC output at all.  When I try the -verbose:gc in the
console mode(putting it in the catalina.bat file), I can see the GC output
on the console.  Am I doing it correctly?  If not, what am I doing wrong?

Thanks
-Manoj Pooleery.
