By GC I assume you mean garbage collection? If so, don't muck with
it, let the JVM optimize garbage collection for you. There should
never be a need to call the garbage collector directly from code.

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?
