eclipse not accepting set heap size in eclipse.ini

Question

I am using IBM rational performance tester with eclipse and have set “show heap status” in windows>preferences>general in eclipse. But when I run my application/performance test it shows java heap space error.

My eclipse.ini is :

-vm

C:\Program Files\IBM\SDP\jdk\jre\bin\javaw.exe

-startup

plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar

-install

C:\Program Files\IBM\SDP

--launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.2.R36x_v20101222

-vmargs=-Xmx1500m

-Xquickstart

-Xms40m

-Xgcpolicy:gencon

-Xscmx48m

-Xshareclasses:name=IBMSDP_%u

-Xmx1947m

-Xjit:disableValueProfiling

But when I checked the heap status in status bar of eclipse as shown in following figure:

It shows “max:512M” but in eclipse.ini I have set it to “-Xmx1947m” as shown in above eclipse file.

Can anyone please tell me why it is showing max:512M in heap status bar in eclipse when I have set it to 1947M?

Answer 1

-vmargs=-Xmx1500m is not a valid entry in the eclipse.ini.

-vmargs must be on a line by itself or it will not be recognized. Since the -vmargs line is not correct all the VM arguments are being ignored.
