Im looking into performance issues with an application running on CF8.
One of the things Im checking is the GC ,
Does anyone know how to pragmatically invoke GC? I know you can manually
click GC if you have Server Monitor available in CfAdmin (which I did until
the 30 days was up and the Standard Edition limitations kicked in).
I know also through Server Monitor you can create alerts that can be based
on memory stats. and that this alert can invoke GC. Can this alert be
created/managed pragmatically?
Based on the JVM Arguments, CF/Jrun will do GC regardless of such alert
existing or not - correct?
The server has a single 2.40Ghz Xeon3220 proc and 2 gigs of ram
Its running Microsoft Window Server 2003/Web Ed. SP2 / IIS / CF8 Standard
(8,0,0,176276).
Its only use is as a CF8 application server.
Java Version is 1.6.0_01.
The JVM Arguments are:
java.args=-server -Xms1000m -Xmx1000m
-Dsun.io.useCanonCaches=false-XX:MaxPermSize=192m -XX:+UseParallelGC -
Dcoldfusion.rootDir={application.home}/../ -
Dcoldfusion.libPath={application.home}/../lib -
Dcoldfusion.classPath={application.home}/../lib/updates,{application.home
}/../lib,{application.home}/../gateway/lib/,{application.home
}/../wwwroot/WEB-INF/flex/jars,{application.home
}/../wwwroot/WEB-INF/cfform/jars,c:\\coldfusion8\\cfx\\java\\CFX_PDF.jar
Never had to deal with the JVM... so I'll be reading up on it this weekend,
but does anyone see any obvious problems with the JVM Arguments?
