[cfaussie] Re: ColdFusion 9 Server Memory Issues
Hi Sean, I notice Java 7 is due for release at end of July. With java 7 you get the released version of UseG1GC garbage collector - rather than experimental option in java 6. Cheers, Carl. Yeah, on 32-bit Windows, 1.4GB is the most you can give it. I pretty much never run CF in production with less than a 2GB heap (usually 2GB min, 3GB max) but of course I don't use Windows in production. On 64-bit servers you can go higher but if you go beyond 4GB, you need to be very careful about the GC configuration you use... Even tho' it's only experimental in Java 6, if you use a large heap, the G1 collector is worth trying (but, as always, it's all about load testing / real live load and constantly tuning the GC configuration to get the best overall performance). -- Sean A Corfield -- (904) 302-SEAN An Architect's View --http://corfield.org/ World Singles, LLC. --http://worldsingles.com/ Railo Technologies, Inc. --http://www.getrailo.com/ Perfection is the enemy of the good. -- Gustave Flaubert, French realist novelist (1821-1880) -- You received this message because you are subscribed to the Google Groups cfaussie group.

[cfaussie] CreateObject of itself
Can anyone suggest a way i can create a new reference to a cfc that i am
already in?
Something like
FooBar.cfc
cfcomponent
cfproperty name=fooProp type=string /
cffunction name=bar output=false
cfscript
LOCAL.tmpArr = [];
for (LOCAL.i = 1; LOCAL.i LTE 10; LOCAL.i = LOCAL.1+1) {
LOCAL.tmpObj = new this;
LOCAL.tmpObj.setfooBar(Some String #LOCAL.i#);
ArrayAppend(LOCAL.tmpArr, LOCAL.tmpObj);
}
/cfscript
/cffunction
/cfcomponent
Obviously new this; wont work.
I want something to replace
LOCAL.tmpObj = createObject(COMPONENT, FooBar);
Ideas?

Re: [cfaussie] CreateObject of itself
Hi Steve
If you're just trying to avoid referencing the component name within
itself, then why not try using
local.metaData = GetMetaData(this);
local.tmpObj = CreateObject(component, local.metaData.fullname).init();
You might want to check the docs to see if fullname is the correct key
to reference, but this sort of idea should allow you to create an
instance of the CFC you're currently in.

Re: [cfaussie] CreateObject of itself
Duplicate works on CFC instances, so Duplicate(this) would work. Of course
it also duplicates the state of the instances variables in 'this', so it
might not be what you want.
Otherwise, try CreateObject(component,GetMetaData(this).name) or
maybe CreateObject(component,GetMetaData(this).fullname). I'm not sure
which is better.

Tho Java 7 being preview it has not been near more vital / loaded CF environments – so early days. For those interested readers a very brief recap on garbage collection. The Java heap is divided into 3 regions: young, tenured/old, and perm. You may also know that young is further divided into eden and two survivor spaces. A minor garbage collection finds all live objects and puts them to one of the survivor spaces. Longer survived objects will eventually move into tenured/old space. Some special objects land in Perm. From what I have gathered the G1 collector memory is divided into multiple regions. Each of these regions will participate in a generation. Some will be young, some to survivor, and others to old. The collector is parallelized (multi-threaded) and will work concurrently with your application (low pause). The minor collection is similar to as current. There is a change to collection of regions that are tenured/old space, there will be no separate collector.
