[xep-support] Re: Generating DITA PDF from oXygen

By the way, setting memory to 12G ( even if you have it) is about enough
memory to create a 24,000 page document.

If you are trying to create something much smaller than that . this is good
indication that the value you are changing is not actually doing what you
think.

Hi Danny,

Firstly, this is not an XEP issue, it's a DITA-OT and its use of Java issue.
There are plenty of support lists and forums for DITA, and also for oXygen.

To use XEP with the DITA-OT, you need to set both JVM AND maxJavaMemory.

To quote from the thread: The values I used were: maxJavaMemory=1024m and
JVM=-Xmx1536m

You can use the oXygen DITA-OT interface to add maxJavaMemory.

Cranking up JVM to 10G or 12G is what I did, and it's wholly unnecessary.

The default for maxJavaMemory is something like 512m, and it's not enough.

HTH,

David

By forked process I think you mean the setting on the oXygen transformation
under Advanced JVM arguments. I have this set to -Xmx10g

By Java environment, I believe this is the settings that start oXygen, so in
my case the oxygenMac.sh file has this

"${OXYGEN_JAVA}" -Xdock:name="Oxygen XML Editor"\

 -Xdock:icon="$OXYGEN_HOME/Oxygen XML
Editor.app/Contents/Resources/Oxygen.icns"\

 -Dcom.oxygenxml.editor.plugins.dir="$OXYGEN_HOME/plugins"\

 -Dcom.oxygenxml.app.descriptor=ro.sync.exml.EditorFrameDescriptor\

 -Xmx12G\

 -XX:-OmitStackTraceInFastThrow\

 -XX:SoftRefLRUPolicyMSPerMB=10\

 -XX:MaxPermSize=256m\

 -cp "$CP" ro.sync.exml.Oxygen "$@"

I'm using the default xep shell script

There are two settings for maxmemory, one if for the Java environment and
the other is for a forked RenderX process.

What are you setting these to?

One is maxJavaMemory and one is maxmemory.

 When I try and run XEP within the DITA PDF transformation I get the
following error:

I'm able to take the FO that is generated with the transformation and run
XEP on the command line and I get the PDF output. I've bumped the oXygen
available memory up as well as the Advanced tab on the transformation and it
doesn't seem to make any difference. Any idea on how to correct this?
