Re: RAM increase
Hi All, Thanks for your reply.I have a doubt whether to increase the ram or heap size to java or to tomcat where the solr is running Regards, satya
Re: RAM increase
When you start the Tomcat app, you tell it how much memory to allocate to the JVM. I don't remember where, probably in catalina.sh.

Re: RAM increase
Hello Lance, form the command line run: export JAVA_OPTS='-d64 -Xms128m -Xmx5g' eventually changing values of Xms and Xmx. Hope this helps.

You will also need to switch to a 64 bits JVM You might have to add the `-d64` flag as well as the `-Xms` and `-Xmx` - Original Message - From: Gora Mohanty g...@mimirtech.com To: solr-user@lucene.apache.org Sent: Thursday, October 21, 2010 2:34 AM Subject: Re: RAM increase On Thu, Oct 21, 2010 at 10:46 AM, satya swaroop satya.yada...@gmail.com wrote: Hi all, I increased my RAM size to 8GB and i want 4GB of it to be used for solr itself. can anyone tell me the way to allocate the RAM for the solr.
