There is a memory dump do analyse the raw-file is about 10.7 GB.
First approach was to run post processing on the server but there is not enough memory.
Following error message was issued:
Errors occurred druing Post-Processing:: dumpname: dynaTrace Analysis Server does not have enough memor for post-processing, need 8,421 MB, having 4,058 MB
Found the description how to configure the server
https://apmcommunity.compuware.com/community/display/DOCDT42/Analysis+Server+Configuration
but unfortunatly it is not possible to increase the memory at that amount.
The second approch was to do the analyses offline with Client/Viewer application. The problem here ist that these applications only support 32bit an a maximumd of 1.4GB (Xmx). So no change to analyse it offline.
Are there 64bit versions of client/viewer availabel. Could not find any in download section.
Is there another possibility to analyse such large heap dumps. E.g. using 3rd party tool.
On the forum i have also found that a conversion to hprof is not possible, is this still valid? (https://apmcommunity.compuware.com/community/pages/viewpage.action?pageId=46628919)

I have my 5.5 Analysis server running on a 64bit machine. I gave it a Terabyte of drive space. The heap size for the analysis server is set to 28GB. I'm trying to post process a 25GB heap I get an error dialog box after 4 hours of post processing. Any help or ideas would be appreciated.
thanks
Tahir

Note that you can install and run the Analysis server on any machine, you can configure its location in the dynatrace Server configuration under Services. This way you can use any machine powerful enough.

Hi Christoph,
The dynaTrace Client does not do any Memory Analysis. It is either done by the dynaTrace Server (pre-production only and not typically recommended) or the dynaTrace Analysis Server. The dynaTrace Analysis Server must have a heap size > the size of the Application Heap. That's what the error message you are getting is indicating.
The only solution is to increase the heap size of the dynaTrace Analysis Server.
thanks,
ted
Actually you can export raw memdumps, import them into a client offline and then postprocess there, however with the 32-bit limitation mentioned above.
