Split WD Components from a DC

[Former Member]

Hello,

I must to migrate some WD Java projects from 7.0 to 7.3; I can migrate all of them, except one.

This DC has 11 WD Components (some of them quite big size); there are no errors within and I should deploy it and test it. The problem becomes when I'm not able to build the DC from NWDS 7.30; the system gives me the following error:

I tried a lot of times... my computer configuration:

- Windows XP

- 3GB RAM memory

What can I do? Is it a machine memory problem? Or is it a server memory problem?

Maybe I should split some WD Components into more DCs... right? How can I do it? Is there some tool for that purpose?

Thanks!!

put this in your nwds configuration file

SapNetweaverDeveloperStudio.ini

-vmargs

-Xmx768m

-Xms768m

-Xmn256M

-XX:ReservedCodeCacheSize=64m

-XX:MaxPermSize=384m

-server

-XX:+UseParNewGC

-XX:ParallelGCThreads=2

-XX:+UseConcMarkSweepGC

-XX:CMSInitiatingOccupancyFraction=60

-Dfile.encoding=UTF-8

-Dosgi.requiredJavaVersion=1.6

-XX:+HeapDumpOnOutOfMemoryError

try to build again.

if not work, delete unrelated dc and build again.
