Looking for the document that shows memory in UCCX 12.5

[garry.engle]

This has been surprisingly difficult to find. 

What is the java heap memory amount in UCCX 12.5? 

We're on 10 now, about to upgrade to 12, and hoping to leave our java heap memory errors behind by getting a bigger amount than 512MB. I figured something like that would be easy to find in UCCX 12.0/5 documentation, but no dice so far.

Thanks!

I'm not sure it's ever been published in a document, and I've only seen it in a defect back around the early 8x days.

A word of caution, if you are overrunning your heap today, it's likely that you will overrun any heap setting, as poor programming of your scripts will create a memory monster or worse a memory leak.  You should be able to do anything in UCCX you need to do on the current heap settings.  Anyway, just my $0.02 worth of opinion.

I do have access to a variety of versions, and it looks like they bumped to the ~750MB area around the 11.x timeframe and it's held steady since.

You're welcome. By the way, Cisco used to publish a handy little reference for best practices when writing scripts, but it seems like it's fallen by the wayside. I'd like to see Cisco bring this back and modernize it. Or perhaps I'll just write one, however, it wont carry the same weight as an official document.

It looks like the page doesn't exist anymore and you'll need to use the cached version, which is a direct link here:
