Increase memory for jMeter on command line
Solution 1
As far as I understand:
- You made changes to
jmeter
script - You're launching
jmeter.sh
script - You want to know why the changes are not applied?
If you changed jmeter
script why don't you just launch it as ./jmeter
?
If you need to start JMeter via jmeter.sh
for any reason, run it as follows:
JVM_ARGS="-Xms1024m -Xmx2048m -XX:NewSize=512m -XX:MaxNewSize=1024m" && export JVM_ARGS && ./jmeter.sh
See Running JMeter User Manual chapter in particular and The Ultimate JMeter Resource List in general for the relevant documentation.
Solution 2
If you have trouble finding it in the logs, then You can use
ps -ef | grep jmeter
this may give you the details( Not a mac user, but I thing ps -ef would work)
The other option is to use jvisualvm, it ships already with jdk, so no extra tool is required.Run the visualvm and the jmeter, you can guess the name of the application ( entry of jemter ) on the left pane of visualvm , click on it, and all the jvm details will be available.
After this you can confirm whether jmeter is availed with 2GB max Ram. And increase if needed.

I am running jMeter from the command line on a Mac. Today it threw an Out of memory, heap space error....
newbie$ sh jmeter.sh Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space at java.awt.image.DataBufferInt.<init>(DataBufferInt.java:41) at java.awt.image.Raster.createPackedRaster(Raster.java:455)
I know I need to increase the memory allocated to it, but not sure how. I looked at this post Unable to increase heap size for JMeter on Mac OSX and found that jMeter script file in the bin folder it mentions and made the below updates..
HEAP="-Xms1024m -Xmx2048m" NEW="-XX:NewSize=512m -XX:MaxNewSize=1024m"
But I am still getting the out of memory error. Do I just need to give it more or am I changing in the wrong place? Could it be I need to restart my whole machine?
