i try to star rockerMQ broker,but i got the error message:
There is insufficient memory for the Java Runtime Environment to continue.
Native memory allocation (mmap) failed to map 8589934592 bytes for committing reserved memory.
An error report file with more information is saved as:
/usr/local/soft/rocketMQ/incubator-rocketmq/distribution/target/apache-rocketmq/hs_err_pid6034.log

and i got something from the error log file about message of memory:
Memory: 4k page, physical 4089840k(551832k free), swap 2621432k(2621432k free)

how can i let the rockerMQ broker working for me
You can reduce the JVM heap size.
Open the distribution/bin/runbroker.sh file of your project and change the following line
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
as
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g"
now broker will only generate a 4G heap .I hope it will solve your problem.Now you can try to build and run.
Try modifying the start shell scripts to make a smaller JVM heap size in your dev/test env

Currently Ignite is taking the default installed OpenJDK 11 JVM heap size. Now, I want to define the JVM initial and max heap size for Ignite Instance. Where exactly I need to define so that it will take the defined JVM heap config to run.
You can use -Xms, -Xmx to set JVM memory parameters.
Here is more information: https://apacheignite.readme.io/docs/jvm-and-system-tuning
and: https://apacheignite.readme.io/docs/preparing-for-production
JDK 11 specific: https://docs.oracle.com/cd/E15523_01/web.1111/e13814/jvm_tuning.htm#PERFM160
In the Ignite logs you could see how much memory was allocated along with other parameters: look for these lines:

I'm using GraphDb Free 8.6.1 in research project, I'm running it with default configuration on linux server having 4GB memory in total.
Currently, we execute quite many CRUD operations in tripplestore.
GraphDB throwed exception in console:
java.lang.OutOfMemoryError: Java heap space
-XX:OnOutOfMemoryError="kill -9 %p"
Executing /bin/sh -c "kill -9 1411"...
Looking into process, GraphDB runs with parameter XX:MaxDirectMemorySize=128G
I was not able to changed, even with ./graph -Xmx3g, process is still running with XX:MaxDirectMemorySize=128G.
I've tried to configure ./grapdh parameter, setting the GDB_HEAP_SIZE=3072m, now process runs with additional -Xms3072m -Xmx3072m parameters, but remains XX:MaxDirectMemorySize=128G.
After update to GDB_HEAP_SIZE=3072m, repository went down again without .hprof file, no exception, nothing suspicious in logs. The following line was flushed into console: Java HotSpot(TM) 64-Bit Server VM warning:
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00007f5b4b6d0000, 65536, 1) failed; error='Cannot allocate memory' (errno=12)
Please, can you help me to properly configure GraphDB tripplestore to get rid of the Heap Space exceptions?
Thank you.
By default, the value of the -XX:MaxDirectMemorySize (off heap memory) parameter in the JVM is equal to the -XMx (on heap memory). For very large repositories the size of the off heap memory may become insufficient so the GraphDB developers made this parameter 128GB or unlimited.
I suspect that your actual issue is actually allocating too much on heap memory, which leaves no space for the off heap in the RAM. When the database tries to allocate off heap RAM you hit this low OS-level error 'Cannot allocate memory'.
You have two options in solving this problem:
Increase the RAM of the server to 8GB and keep the same configuration - this would allow the 8 GB RAM to be distributed: 2GB (OS) + 3GB (on heap) + 3GB (off heap)
Decrease the -Xmx value to 2GB so the 4GB RAM will be distributed: 1GB (OS) + 2GB (on heap) + 1GB (off heap)
To get a good approximation how much RAM GraphDB needs please check the hardware sizing page:

Currently we are encountering an problem, our java application can run smoothly with JRE6, but for JRE7, it will report "Could not create the Java virtual machine" sometimes and failed to start program. we have "-Xmx1024m" option in the launch command line.
after searching in google, people suggest check the max heap size that can be requested in PC. then I tried below ones.
for JRE6,
C:\Users\joey>java -Xmx1214m -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) Client VM (build 20.45-b01, mixed mode)
C:\Users\joey>java -Xmx1215m -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
for JRE7,
D:\Program Files\Java\jre7\bin>java.exe -Xmx930m -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode)
D:\Program Files\Java\jre7\bin>java.exe -Xmx931m -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
And when i close most processes in PC and free memory to 2.5 GB, for JRE7, it will succeed with 1094m, like below.
D:\Program Files\Java\jre7\bin>java.exe -Xmx1094m -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode)
D:\Program Files\Java\jre7\bin>java.exe -Xmx1095m -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
It seems that the max heap size that JVM can request is related with system available memory size, does someone know the exact relationship?
Is there some way to enable tracing logs of JRE when creating JVM?
Thank you!

Joey
I faced the same issue on various Windows OS flavous (Win7, Win2008R2) while having enough free RAM (3-5G), when switching from jre6_20 to jre7_51 (both 32 bit VMs)
Using vm args -Xmx1300m and -XX:MaxPermSize=256m on java 6 the VM is able to start. However, with java7 I had to lower down startup max memory (xmx with 100m or permgen with 100m) in order to be able to start VM.
The interesting part is this: if I restarted my box, the jvm 7 started with original vm args (-Xmx1300m and -XX:MaxPermSize=256m) so I suspect the root cause might be the OS with JVM combination.
I know that on Windows OSes - 32 bit VMs expect to have a single large chunk of memory, but cannot use the maximum process memory size will range from 1.4G to 1.6G (because of additional constraints)
Any troubleshooting pointers? Oracle does not provide any information in java7 release notes (or I could not spot those)
I have a similar problem Windows 7 64bit, no JAVA_HOME set nor in PATH
This fails

Nothing else is consuming a lot of resources (memory, etc, I did have oracle database running locally, but shut it down)

I want to increase the heap size of my Glassfish. For that, I know that I can go up to 4GB:

But I am getting the following error:

The server exited prematurely with exit code 1.
Before it died, it produced the following output:

I found the problem. For some reasons which I do not understand, the "-d32" argument was passed in the command, asking to start in 32 bits mode. When adding
<jvm-options>-d64</jvm-options>
to the domain.xml file, glassfish starts. Please note that this option is not present by default in the file.
you must be using a different Java install when doing the "-version" and from within GlassFish. I can reproduce the same error with the default "java" in Mac OS' path but not when using an absolute path :
% /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Xmx2300m -version

% java -Xmx2300m -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
Could it be that you don't have enough disk space on your system? Reserving 4GB of RAM may require MAC OS to expand swap space, and you may not have the disk space to do this. Unfortunately, this has burned me before :-/
I got this error on trying to get the Java search process UP(start a java process). I am setting the address space using the RLIMIT_AS.
Please help me to get past this error.
I have doubts about the VM Arguements. (See below).
Is there any way to get past this issue without changing the configurations. (VM Arguements)
