force TomCat to use more than 8gigs of RAM

So, I figured someone out there on the list knows this...

The JSS Setup Utility only allows for a maximum value of 8gigs of RAM set to the JSS for TomCat. Well, I upgraded my server last night to 24gigs of RAM and I want TomCat to use at least 16Gig, if not more. How is this done? Do I have to edit a file?

Also, Jamf, please add this as a feature request in a future release of the JSS Setup Util. I would like to set the Max Packet size for MySQL and more than 8gigs of RAM to TomCat to any value I desire.

Thanks

Tom

    Two things this morning:

    1. In terms of setting the memory usage on TomCat, I would personally send the request to support directly. Perhaps there are reasons why they limit to 8GB in the setup utility, but they will certainly be able to help you do it if they feel it will help at all. There may be limitations within TomCat itself that don’t offer any more performance benefit to doing this, but I’m not a developer and couldn’t tell you that.
    2. You can set the Mac packet Size in the JSS setup utility up to 16MB: Database -> Troubleshooting -> Mac Packet Size

    Cheers,

    Craig,

    Yup, I agree that there may be reasons behind it, but I already know for
    a fact my deployment needs more juice in the JSS. I have issues with
    log files not being able to flush because they get larger than 16megs,
    so I set my max packet size to 128megs using the MySQL GUI tools, but
    you can also set this from the command line or something like
    phpmyadmin.

    I will drop their support an email.

    Thanks

    tom
