Hallo Georg,
Thank you for your answer.

I do know that page and have read it before, just reread it again.

What bothers me is:
If I have a snapshot, how long will it be around? It will have a weak reference, when a new snapshot is created (5.2 and later). Does that mean it will eventually be garbage collected even if the editingContext it resides in is not garbage collected? Or does it need to be decremented to 0 until it is released? How many snapshots of the same table data does it need for one snapshot to be decremented to 0/released/ freed for garbage collection?


Perhaps I'm not seeing the trees in the wood, but I do have to get memory usage down and this could be a possibility why emory usage is so high in the first place, perhaps.

Regards,

Ute

Hi Ute,

have a look at http://en.wikibooks.org/wiki/Programming:WebObjects/EOF/Using_EOF/ Caching_and_Freshness
(Yes, I just posted it before Mike Schrag could do so :-)
This will give you some insights how to treat this very common kind of problem.


Regards,
Georg

Hallo,
Does anyone know whether WebObjects will keep old snapshots in his memeory, i.e. I have a very log timestampLag. So WebObjects has some data fetched, then the data is needed again and fetcht again... will it keep the first fetch/snapshot or will it get rid of that or repopulate it?



Thanks for some clarification,

Regards,

Ute
