How to specify JAVA_OPTS for for solr?

Question

I am using on apache solr3.6 (naive user) and have data in the multicore of solr folder.

D:\setup\apache-solr-3.6.0\example\multicore

The current version of tomcat I am using has startup.bat in its bin folder so I specified JAVA_OPTS in it as below:

rem Get remaining unshifted command line arguments and save them in the

set CMD_LINE_ARGS=
:setArgs
if ""%1""=="""" goto doneSetArgs
set CMD_LINE_ARGS=%CMD_LINE_ARGS% %1
shift
goto setArgs
:doneSetArgs

set "JAVA_OPTS=%JAVA_OPTS% -Dsolr.solr.home=D:\setup\apache-solr-3.6.0\example\multicore"

call "%EXECUTABLE%" start %CMD_LINE_ARGS%

:end

However I recently downloaded a new version of tomcat which contains no startup.bat in it but some .exe file (may be tomcat.exe) instead, double clicking which will start the tomcat server.

So how do I specify JAVA_OPTS and -Dsolr now?

Answer 1

As @Bhanu said... Go to tomcat istallation folder, inside Apache Software Foundation\Tomcat 6.0\bin you'll find tomcat6w.exe run it. It will open tomcat configuration window

Open java tab and specify the multicore path inside java options as -Dsolr.solr.home=D:\setup\apache-solr-3.6.0\example\multicore

Answer 2

For setting up Solr Home option with Tomcat refer to details.

Also, more information would be available at SolrTomcat

Answer 3

In newer versions of tomcat say tomcat7, you will find tomcat7w.exe in tomcat/bin. Run it select Java tab and in Java Options pane write your path. It is quite easy compared to JNDI way.
