I get a Java Heap space error when updating changes

Eddie Breeveld (61●1●23●30) | 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.

It's all about the answers!
