this error appears when I try to start the server in netbeans
Initial heap size set to a larger value than the maximum heap size
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=192m; support was removed in 8.0
Picked up _JAVA_OPTIONS: -Xms1024M
How can i solve it? this is the error
For this issue you need to edit glassfishes heap size. As of now the max heap size it less then the min heap size.
To do this edit the domain.xml it usialy will be located in C:\Program Files\glassfish-4.1.1\glassfish\domains\domain1\config\domain.xml
Inside it look for Xmx. Edit it the number to be 2048 this increases the max heap size to about 2 Gigabits. As your min size is about 1 Gigabit.

I am trying to get JBoss WildFly 15.0.1 Final to start on a rather small ubuntu 14.04 vServer. The server has only 2 GB of RAM.
I tried to start WildFly many times without success. The JVM seems to require a lot more RAM than I had ever expected.
Here's the console output:
root#t2g55:~# service wildfly start
* Starting WildFly Application Server wildfly
* WildFly Application Server failed to start within the timeout allowed.

As you can see I specified JAVA_OPTS: -server -Xms768m -Xmx1536m ..., which I thought should suffice for a WildFly server to start. Please not, that the standalone.xml has a datasource defined to a MySQL DB.

QUESTION:
Can this be solved with this amount of memory or do I simply have too few RAM?
What else could I probably try?
I don't really want my provider to go up with the mem successively only to find there's some other problem with Java, the JVM or anything...
Thanks
EDIT 1:
The vServer provider uses OpenVZ for its virtualization.
Info: they just pushed my to 4GB, then once, I got JBoss up and running. After reboot WildFly again refuses to start: same thing, not enough memory (even though I switch between Java 8 and Java 11 runtimes).
CMD to start JBoss WildFly: sh /opt/wildfly/bin/standalone.sh &, standalone.xml appears to be OK. I removed the ExampleDS, three entries commented.
It was indeed a server virtualization issue with OpenVZ.

Hi,
the problem was with the user_beancounters, that is with the privvmpages, these were set too low.

I don't know exactly what he did in detail, but that resolved it.
I now run on a 2GB machine without any problems and memory usage of mysqld + standalone.sh (WildFly + webapp) is around 800 MB.
For google certification , we need to run Compatibility test suite on the android device(stb) .
I have done the setup for CTS on a Linux machine.
I am getting below error while running cts-tradefed on the machine.
./android-cts/tools/cts-tradefed
Invalid maximum heap size: -Xmx4g
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Can anyone give the solution for it?
Just open android-cts-[X.X]_[rX]-linux_x86-arm/android-cts/tools/cts-tradefed from any text editor and change line number 131 $RDBG_FLAG -Xmx4g with any memory size which is less than your RAM size e.g. Xmx3g
Also check if you are using Linux 64Bit version. This issue might occur if you are using 32Bit(which is not supported)
I'm getting error messages on Eclipse (Mac):
Invalid maximum heap size: -Xmx5120m-Djavax.net.ssl.trustStore=/usr/local/keystore/JavaKeyStore.jks-Djavax.net.ssl.trustStorePassword=changeit-Dtls.key.store=/usr/local/keystore/JavaKeyStore.jks-Dtls.trusted.store=/usr/local/keystore/JavaKeyStore.jks-Dawsmock.directory=/ijmeang/elis/s3-mock-Dcatalina.base=/usr/local/workspace/workspace-eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0-Dcatalina.home=/Library/Tomcat-Dwtp.deploy=/usr/local/workspace/workspace-eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps-Djava.endorsed.dirs=/Library/Tomcat/endorsed
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
How can I fix this?
Here are the arguments on Eclipse:
-Dcatalina.base="/usr/local/workspace/workspace-eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0" -Dcatalina.home="/usr/local/Tomcat-7.0.6.9" -Dwtp.deploy="/usr/local/workspace/workspace-eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps" -Djava.endorsed.dirs="/usr/local/Tomcat-7.0.6.9/endorsed" -Xss768m -Xmx5120m -XX:MaxPermSize=5120m -DmasterPropertiesLinux
I would suggest trying to decrease your value of -Xmx5120m, as described here:
https://wiki.eclipse.org/FAQ_How_do_I_increase_the_heap_size_available_to_Eclipse%3F
Some JVMs put restrictions on the total amount of memory available on the heap.
It depends on what Java are you using. If you are using 32 bit Java you may not be able to use more than 2GB.
We are running on 32bit windows and since upgrading from 1.4.1 to 2.2.2, we are seeing the following memory in stdout (numbers not exact):
INFO: Database 'BLAH' uses 770MB/912MB of DISKCACHE memory, while Heap is not completely used (usedHeap=123MB maxHeap=512MB). To improve performance set maxHeap to 124MB and DISKCACHE to 1296MB
With 32bit, we can only set a max of Xmx + storage.diskCache.bufferSize ~= 1.4gb without getting OOM or performance issues. Any combination of different sizes of either of these two configurable variables results in a variant of the above message.
Is there a way to suppress the above profiler/memory checker messages?
You can disable the profiler with:
java ... -Dprofiler.enabled=false ...
Set that configuration in your server.sh or in the last section of config/orientdb-server-config.xml file.
I have deployed my java application on jboss and linux 2.6.32 .
The machine has 8 gb of memory, but when I run the application on openjdk using
JAVA_OPTS="$JAVA_OPTS -server -Xms2048m -Xmx2048m -XX:MaxPermSize=700m
-XX:NewRatio=3 -XX:+DisableExplicitGC -XX:+UseParallelOldGC -XX:ParallelGCThreads=4 -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dofbiz.home=adasdfasdf".
It's working fine.
But when i try to run the same on jdk 1.6 its giving me out of memory error as below:
There is insufficient memory for the Java Runtime Environment to continue.
