Print Deltas button of Metadata Comparison tool freezes NWDS

[Former Member]

I have been trying to analyze the conditions under which the Compare Meta Data / MetamodelMerge functionality causes NWDS to crash when creating the XML report, and I suspect file size may have something to do with it. A project with four conflcts can successfully print the XML deltas report, but a comparison with 23 conflicts will output an empty XML file and freeze NWDS.

Is there a connection between the amount of data being output and the success of creating the XML file? Does anyone know what the size restrictions are (if any) and if they can be modified in some startup parameter setting or class file?

Hi,

Try starting your NWDS with -XX:MaxPermSize=512m. Probably too many arrays being generated.

NWDS still freezing after changing -XX:MaxPermSize=512m. Any other ideas? Are there any guidelines for setting VM parameters for NWDS?

You could also try to add "--vmargs -Xmx512" or similar. But I would recommend to open an OSS message on component BC-DWB-WD-JAV.

I already bumped up the VM memory arguments and it didn't help.

Thanks for identifying the object for me - I'll pursue an OSS message.
