I get a Java Heap space error when updating changes

Eddie Breeveld (6112330) | asked May 22 '15, 8:06 a.m.
(Can't upload an image showing the problem because I don't have enough reputation.  What a waste of time).

We are getting "Problem occurred" errors when changing flow targets.  The dialog says (which I have to type out manually):
'Updating changes' has encountered a problem.  
An internal error occurred during: "Updating changes".

An Internal error occurred during: "Updating changes".
java.lang.OutOfMemoryError: Java heap space
What settings do we need to overcome this problem.  We are running 64-bit laptops with 16GB memory installed.

Client: RTC 4.0.7.  Windows 7.  Server: 4.0.7

Try adding:

-Xmx2048m [ or larger ]

into the eclipse.ini  This will be in this relative path:  jazz/client/eclipse/eclipse.ini ( or jazz\client\eclipse\eclipse.ini if you need that translation )  The beginning of the path depends on how the RTC client was installed.

Very helpful.  Thank you Kevin.  We set it to -Xmx4g, even though the maximum we have seen used is about 1200m.

Nice !
I have my 1st example ( 2g ) in my Eclipse Luna + RTC 5.0.2 and don't run into out-of-memory.
