Thank you for your prompt response Philip

I didn’t have any luck with the plug-in version of TRex. Already played with the –Xmx variable, but Eclipse gets unbearably slow during project buildup.

I tried the standalone installer for TRex and it seems to be working somewhat better. Initially it would crash whilst creating (checkout) the Project (which is too large ~ 1.5GB and 25K files in total)! So, I edited –Xmx and set it to 1500. That allowed me to Checkout the code. Looking at the Task Manager, trex.exe tops at 1.620.000K– which means it’s already utilized the 1500 I allocated to it. I tried setting the –Xmx to a high value e.g. 2000 or more, but Java would through up an error and TRex wouldn’t start. My system has 4GB of RAM, so I should have been allowed to use more e.g. 2000, but the JVM won’t have it L Any workaround to this?

Even though TRex is actually running and sort of it does what I want – it’s very slow; it often crashes after some light-to-moderate usage. Are there any options from within the TRex advanced config that I can safely disable – in order to reduce memory usage?

Regards

Jason

Dear Jason,

from the looks of it, it seems like a memory issue (GC overhead limit exceeded). You mentioned working with admittedly rather large TTCN-3 code base which would also suggest potential memory issues. The general remedy is trying to increase the memory settings even further (-Xmx1024m or more). Your intuition is otherwise correct, this is indeed one of the intended functionalities of TRex. But before you perform any of those actions, you need to make sure that initial processing is finished (depending on the codebase size it may take a few minutes to parse and index all resources).

It could also be a bug of course, and I will have a look at this as far as time permits, but generally memory consumption with large test suites is a known limitation of the current implementation and careful memory selection mostly helps (~2 GB for 200 000+ LOC TTCN-3 code, for example).

Best regards,

Philip

Dear all

I am trying to use the T-Rex build-in functionality “open declaration” and “find references”. Nothing seems to happen and after a while (hanging Eclipse) I get the following errors:

I am using the plugin of T-Rex on Eclipse 3.7.2 . As recommended, I have increased the mem usage to 512m, but still seems to have no effect. I am using Subclipse for my TTCN script repo (which is relative large) and the default Java perspective (if that has anything to do with it).

What I want to do here is to enable Eclipse to ‘resolve’ functions, declarations etc so that I can navigate through the code quicker – without having to manually look where a particular function is stored. I presume T-Rex should allow me to do this, right?

Any thoughts that might help me figure what’s wrong here?

Cheers

Jason
