Question

PE Java Heap Size

  • June 1, 2010

Well, got my 38,000 page book up to PTC to see if they can get it to compile. They got the 13,000 page chapter to PDF stably...something I haven't been able to do yet.

Do any of you have any experience setting the Java heap size for the PE?

Setting Tomcats appears rather straightforward, but that doesn't seem to affect the PE java services.

Thanks

    Hi John-



    Have you tried the "set javavmmemory" setting in your init.acl file on
    PE?

    Nope - thanks!

    Tried that, got Java console up and running and it is showing 3 java processes.

    On the heap memory usage page, Apache is set to 266MB max, Sun to 64MB and Arbortext pe\hc\consumerui.jar to 64MB max...setting javavmmemory=2000 didn't raise any of those max values.

    Will test it again...highly annoying that it takes at least an hour for it to crash.

    Anyone know how to set APTJAVAVMARGS to increase java heap size?

    Something like this in autoexec.bat? The docs just say use it but give zero examples...

    Set APTJAVAVMARGS -Xmx2048m

    Hi John-



    Autoexec.bat isn't really used any more. To set up a persistent
    environment variable, right click the "My Computer" icon, select
    Properties, then select the Advanced tab, click Environment variables,
    and add the variable using the dialog that pops up. (That's XP; it will
    be a little different in Vista, but should be pretty similar.)

    I have an init ACL that says:

    if (!java_init(0)) {
    set javavmmemory=1024
    set javavmargs="-Xss2m"
    }

    Provided by support at one time or another.

    and by "init ACL" I mean an acl file (mine is named set_javavmmemory.acl)
    stored in PE's custom/init folder.

    I should follow my own "style" and split out the javavmargs command into
    its own ACL (set_javavmargs.acl) but I suspect, back when I set it up (and
    the way I'm thinking now), I don't know how timing on those ACLs might
    impact the pair of commands working or not.

    It ain't broke ...

    Thanks

    Looks like back at 5.2 M120 Arbortext set it up so it could go in an environment variable and get it out of init.acl with APTJAVAVMARGS, they just don't bother to say how to use it *beats head on desk*

    I tried it in an init.acl for the doctype but can't tell that it changed anything.

    From what I can tell in a 32-bit environment you are limited to a setting of 1348m. I put 2048m in a system environment variable (ugh, autoexec.bat was great! Thanks Clay...) and Arbortext couldn't start a JVM session. Got down to 1100 and it is still too much.

    Putting it in custom\doctype\production\instance.acl worked like you have it as well as putting it in as an environment variable a la Clay's instructions. Both equally crashed when set too high!

    Hi John-



    Maybe there's an issue with the values you're trying. There might be
    some useful info here:

    The main error is that 2048 isn't valid in a 32-bit environment...I set it to 128m just so I could get back to testing and that's double the default...that works now.

    For one app I worked on we used to routinely set it to 512m, so you
    should be able to go at least that high without any problems.
