At the risk of appearing foolish to a lot of people… where do I adjust the memory setting in XCode? I’ve gone to the target, and pasted the command line changes into the “pure java” field. But my startup parameters don’t change. Where does it really belong?

There are a number of things that can be done to resolve this.

1. Allow your application to use more memory by increasing the heap size.

[This is good if you are running your app with too little heap space]

2. Make your application use less memory by qualifying your fetches more precisely.

[May not be possible in some cases]

3. Make your application more efficient by using "Raw Row Fetching"

[Uses less memory than "real" objects]

[Makes your code database specific in some cases, but allows "real" fetch limits]

[Can still make "real" enterprise objects from raw rows when needed]

Hello,

My program loads a great deal of data from the database. I process it, then attempt to “free” the memory. My code looks vaguely like this:

For (all objects) {

EOEditingContext tmp = new EOEditingContext();

tmp.invalidateAllObjects();

tmp = null;

System.gc();

}

Even with this, I’m running out of memory. Any hints on making EO throw away everything it knows about?
