I am trying to install elastic search in Linux VM but could not able to start the service though it has java installed. I am getting following message while elasticsearch script runs.
[xxxx#ABCWCW0ASMGNJ01A bin]$ java -version
java version "1.7.0_65"
OpenJDK Runtime Environment (novell-2.5.1.2.el6_5-x86_64 u65-b17)
OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)
[xxxx#ABCWCW0ASMGNJ01A bin]$ ./elasticsearch
Error occurred during initialization of VM
Too small initial heap for new size specified
I have downlaoded 2.3.2 from elastic search website. After initial google I did set the ES_HEAP_SIZE=1g in bash_profile but still no luck. Can you thow some light what could be issue.
Thanks
It seems you don't have enough heap space to start elastic. Please go to increase the java heap size permanently? and do the needful.
Depending on the flavor of Linux you are using, you may need to use a text editor to update the following file to increase the heap size.
/etc/sysconfig/elasticsearch
(uncomment the line 'ES_HEAP_SIZE=' and set this to half of the allocated virtual RAM for the VM)--Based on: https://www.elastic.co/guide/en/elasticsearch/guide/current/heap-sizing.html
I will caution you to read this as well afterwards if you see something like "Unable to lock JVM memory" in your elasticsearch application log after starting it up:
https://github.com/elastic/elasticsearch/issues/9357
I ran into problems myself with trying to use the environment variable method on Centos 6 and 7.
You may also want to try using the Kopf plugin (open source) to get some simple visibility:
https://github.com/lmenezes/elasticsearch-kopf
Using the following general instructions of course:
https://www.elastic.co/guide/en/elasticsearch/plugins/current/installation.html
If you don't know where certain things are located for elasticsearch on your system, please use the below defaults listing as guidance:
https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-dir-layout.html
The root cause of the problem you are experiencing is most likely related to the startup script being used to bring up your instance of elasticsearch on the VM and it not utilizing the environment variable as expected. I hope you don't mind the extra information, I'm just trying to help you save some time.

I am running nest project on t2 micro. Initially it was working fine but now after adding some other modules, it hangs while making build and says "Javascript heap out of memory".
Please help me with the possible reasons on why this might happen.
--max-old-space-size can increase heap memory
connect ssh to ec2 and open the .bashrc file using nano like so:
nano ~/.bashrc
The remaining steps are similar with the Mac steps from above, except we would most likely be using ~/.bashrc by default (as opposed to ~/.zshrc). So these values would need to be substituted!

I have a problem compiling FMU's in Jmodelica. for a medium size model I get the following error.
I already chanded the runtime parameter of JAVA in control panel and also tired setting the JVM allocated memory as high as possible using Xmx command. I'm running it on a pc with 128GB RAM.
Does anyone know how can I solve this issue in Jmodelica?
The JVM that is being used from JModelica does not take into account the system settings for the JAVA runtime parameter. You'll need to set it in the compile_fmu command. I.e.
compile_fmu(...., jvm_args="-Xmx10g")
I have followed all the suggestions I can find.
I am running the current version on redis on windows 2008
I can run fin from command line
I can install the service but it doesnt run
I do...
redis-server --service-install redis.windows.conf
and get "redis successfully installed as a service"
Then I try to start the service doing...
redis-server --service-start redis.windows.conf --loglevel verbose
and get Redis service failed to start
I have made sure I have the .net framework 4.5.2 installed, I have tried with the firewall off and have played with security on the folder.
Anyone have any ideas?
(Merry Christmas all)
Start redis server from the command line instead of as a service and it will display a more useful error message. If you are just using the default configuration it is most likely a problem with the maxmemory/maxheap configuration.
C:\redis>redis-server.exe redis.windows.conf

The Windows version of Redis allocates a memory mapped heap for sharing with
the forked process used for persistence operations. In order to share this
memory, Windows allocates from the system paging file a portion equal to the
size of the Redis heap. At this time there is insufficient contiguous free
space available in the system paging file for this operation (Windows error
0x5AF). To work around this you may either increase the size of the system
paging file, or decrease the size of the Redis heap with the --maxheap flag.
Sometimes a reboot will defragment the system paging file sufficiently for
this operation to complete successfully.
Please see the documentation included with the binary distributions for more
details on the --maxheap flag.
Redis can not continue. Exiting.
In my case the default commandline config did not have logging enabled and the service one did. And no place where it complains about that.
Try creating the directory ./Logs.
Old question, but I came across it while trying to get a Win7x64 install working using binaries Redis-x64-2.8.2101. Couldn't get it to start despite fiddling with various options, no meaningful error given when run with the config, and only an apparently spurious disk space error when run natively.
There appears to be a issue on the github related, linked here for future benefit: https://github.com/MSOpenTech/redis/issues/267
when I typed java -Xms2M in AIX ,but I got this kind information , the java version is IBM java 1.6.0
JVMJ9GC020E -Xms too large for heap
JVMJ9VM015W Initialization error for library j9gc24(2): Failed to initialize
Could not create the Java virtual machine.
I am sure the machine has enough memory, it has 63232MB , so I don't know how to fix it. who know how to fix it ? Thank you .George
we missed some system environment properties ,so it caused this error. now it fixed .
I am not an expert on JAVA_OPTS, but I am getting an error in my grails app related to Permgen space. Now I receive a recommendation from grails blog to set JAVA_OPTS to this value:
JAVA_OPTS="-client -Xmx256M $JAVA_OPTS"
I do understand the other values except '-client'. What does it really mean? I can't find the significance of it in books.
The -client and -server options are intended to optimize performance for client and server applications; the default varies by platform, where typically client-oriented platforms (Windows, MacOS) get the client VM by default, and typically server-oriented platforms (Linux, Windows Server) get the server VM by default. More information is available here: http://download.oracle.com/javase/6/docs/technotes/guides/vm/index.html
Basically, the client VM is optimized to start up quickly and use less memory, while the server VM is designed for maximum performance after start-up.
Usually, there is -server and -client,
-client starts faster than -server.
Nowadays, in some versions, like AMD64 version, it does nothing, there is only server version.
