default heap size for solr 5.0? (-Xmx param)
Hello,
I am a solr beginner. Anyone knows how solr 5.0 determines the max heap
size? I can't find it anywhere.
Also, where whould you activate jmx? Would like to be able to use visualvm
in the future I imagine.
I have a custom nssm thing going that installs it as a window service that
simply calls java -jar start.jar
cheers

You could also check the default memory by starting solr with the -V
parameter for verbose output. It will show your output like this.
If your are startinf solr with script present in bin directory using this
command
*./solr -c -V*

Posted by Karl Kildén <ka...@gmail.com>.
Actually the reason I did not use the solr script was that I didn't really
get how to make a window service out of it from nssm.exe. I tried doing a
.bat that called solr with start -p 8983 but seems it just loops my command
rather then run it.
Thanks for the help / Karl

Well, the new way will be the only way eventually, so either you learn
the old way then switch or learn it now ;)...
But if you insist you could start with a heap size of 4G like this:
java -Xmx4G -Xms4G -jar start.jar
Best,
Erick

Thanks!
I am using the old way and I see no reason to switch really?

The default heap size is 512m. This is hardcoded in the bin/solr
script. You can override that with the -m parameter.
If you are not using the bin/solr script and are instead doing the old
"java -jar start.jar" startup, the default heap size is determined by
the version of Java you are running.
Thanks,
Shawn
