JVMJ9GC020E -Xms too large for heap

Question

I am using ${JAVA_HOME}/java -Xms512m

I am getting an error :

---------------------------------------------------
JVMJ9GC020E -Xms too large for heap
JVMJ9VM015W Initialization error for library j9gc23(2): Failed to initialize
Could not create the Java virtual machine.
--------------------------------------------------

we have 32 bit JVM . can this be solved without updating JVM to 64 bit ?

Only `-Xms` and not `-Xmx`? Also, which JVM is that? Oracle's, another one? — fge, Oct 28 '16 at 08:04

You can try also setting a value for Xmx:

${JAVA_HOME}/java -Xms512M -Xmx1024M

From what I read here, the default value of Xmx is usually 256MB, which is less than what you specified for Xms. Xmx controls the maximum heap size, and if Xms were larger than the available maximum, it might explain the error you are seeing.

4GB is the largest address which can be supported by a 32 bit system, but your Xms value is not really close to this.
