Doc Text:	Previous versions of JBoss EAP could fail to start when run in a Windows 32-bit JDK environment with the default memory settings. In this release of the product, the default memory settings have been lowered to ensure a successful start on a wider array of JVMs. Customers who rely on the default JVM settings are advised to review their configuration and adjust JVM parameters based on their requirements.

Description Tomaz Cerar 2013-10-25 12:51:44 UTC

This is bug is related to 956281

We fixed standalone startup scripts but same problem applies to domain mode.

Difference with domain start is that startup scripts are ok, but default settings for server.

this settings are part of domain.xml and are as such platform independent.
I would like to change xms & xmx to 1G for both.

Andy WDYT we should do here? 
"problem" is that this would apply also to all other platforms not just windows.

BZ 956281 is in ASSIGNED status now, it's resolved yet. Fix for Windows 8 which are not supported in EAP.

BZ 956281 claims that we should improve EAP usage on Windows 8 with 32bit JVM for development. 

This BZ is about domain mode which is not used for development. It's used for deployment across large number of nodes + centralized node management. We shouldn't change default JVM values for this mode.


Current status (EAP 6.2.0 ER6) for standalone mode:
standalone mode - Windows             ==> -Xms1G -Xmx1G
standalone mode - Linux/Solaris/HP-UX ==> -Xms1303m -Xmx1303m


Proposed status for domain mode:
domain mode - Windows             ==> <heap size="1000m" max-size="1000m"/>
domain mode - Linux/Solaris/HP-UX ==> <heap size="1000m" max-size="1000m"/>
