Hello guys, I'm new to elasticsearch and i'm following this tutorial ([http://bin63.com/how-to-install-elasticsearch-on-windows](http://bin63.com/how-to-install-elasticsearch-on-windows)) to install it in the windows environment. The JDK/JRE in use is JRockit 1.6 (last version). I faced a problem when running the .bat file, and i can't find a solution: _Unknown option or illegal argument: -XX +UseParNewGC._ _Please check for incorrect spelling or review documentation of startup options._ \* \* _Could not create the Java virtual machine_ \* \* My \*JAVA\_HOME \*is pointing directly to \*C:\Program Files\Java\jrockit-jdk1.6.0\_37-R28.2.5-4.1.0\bin\java \*and my \*Path \*variable is: \* %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0;%JAVA\_HOME% \* Both the erro and my global variables can be found in the attached files.

For JRockit VM, you can safely disable (comment with "REM") the JVM options in elasticsearch.bat starting with "-XX", because they are only valid for HotSpot VM.

Sorry Jorg, what should i do to get it solved? Run REM + elasticsearch.bat? It isnt just a warning message, the engine is not initiating ( [http://localhost:9200/](http://localhost:9200/)) Em quinta-feira, 21 de fevereiro de 2013 10h36min51s UTC-3, Jörg Prante escreveu: > For JRockit VM, you can safely disable (comment with "REM") the JVM > options in elasticsearch.bat starting with "-XX", because they are only > valid for HotSpot VM. > > Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You have to modify the start script. Pick your favorite text editor, open the file %ES\_HOME%\bin\elasticsearch.bat (I hope this is correct Windows syntax), in doubt, open the File Explorer to find the file, it's in the bin direcotry where you installed Elasticsearch. Now, add the letters "REM " in front of the lines with the active JVM options starting with "-XX". "REM" means remark and is marking a comment line in Windows batch files. You will notice there are already lines with -XX options that are marked with REM so it should be very easy.
