Re: java memory size   
Same as on windows -Xmx724M

Which would look like for IDE

eclipse/eclipse -vm /usr/lib/jvm/java-6-sun-1.6.0.06/jre/bin/java -vmargs -Xmx724M -XX:MaxPermSize=128m

(the other one another heap size for string objects which sometimes it is running out of)

Re: java memory size   
Yes it is an argument to qde found in eclipse folder (after -vmargs), or you can put it in qde.ini.
If you talking about qde script which is in bin - you need to check if it passes arguments to actual binary.

Re: java memory size   
Aha - but passing -Xmx1024M to qde is accepted - but ignored!

I had to change my system qde.ini to get it to work!

Re: java memory size   
Command-line argument:

    -Xmx<size>

e.g., -Xmx1024M

If this is for an Eclipse-based product, the easiest way to specify this
is by appending this arg on a new line in the ini file (e.g., qde.ini or
eclipse.ini) following the -vmargs line.

HTH,

Christian
