Re: Solrcloud for Java 1.6
i have solrj5 client for 1.7 converted into 1.6 and solr instances running with 1.7.

Solr search and index rate optimization
i wanted to ask that i need to index after evey 15 min with hard commit (real time records) and currently have 5 zookeeper instances and 2 solr instances in one machine serving 200 users with 32GB RAM. whereas i wanted to serve more than 10,000 users so what should be my machine specs and what should be my architecture for this much serve rate along with index rate. my index size is 30GB increases gradually. Thankyou in advance and i am newbee hoping to get response
Re: Solrcloud for Java 1.6
i have solr5.0.0 installed in one machine with JVM specs java 1.7 32GB RAM now from another machine i am sending query request to this machine with specs JAVA 1.6 so what really happening solr5.0.0 (1.7) is communicating with solrj5.0.0(1.6) provide your architecture detail ill further explain it On Fri, Jan 8, 2016 at 10:54 AM, Aswath Srinivasan (TMS) < aswath.sriniva...@toyota.com> wrote: > Thanks for the responses guys. > > >> i have solrj5 client for 1.7 converted into 1.6 > > Can you please explain this part with little more details? > > Thank you, > Aswath NS > > > -Original Message- > From: Aswath Srinivasan (TMS) [mailto:aswath.sriniva...@toyota.com] > Sent: Thursday, January 07, 2016 9:51 PM > To: solr-user@lucene.apache.org > Subject: RE: Solrcloud for Java 1.6 > > Thanks for the responses guys. > > >> i have solrj5 client for 1.7 converted into 1.6 > > Can you please explain in part with little more details? > > Thank you, > Aswath NS > > -Original Message- > From: Zap Org [mailto:zapor...@gmail.com] > Sent: Thursday, January 07, 2016 9:44 PM > To: solr-user@lucene.apache.org > Subject: Re: Solrcloud for Java 1.6 > > i have solrj5 client for 1.7 converted into 1.6 and solr instances running > with 1.7.

Re: Solr search and index rate optimization
thanks for replying currently my machine specs are 32 GB RAM 4 core processor windows server 2008 64bit 500 GB HD 16 GB swap memorey now the already running machine with cpu usage not more than 10% already consumed all the RAM and now started to use swap memorey what my guess is my server will chok when swap memorey will end. i am only running solr and ZK instances there any wild idea what is happening and why memorey consumption is too high. all the field cache and query caches are set to 1GB in solrconfig and along with serving queries i am running delta after every 15 minute.

Re: Solrcloud for Java 1.6
hello shawn yes it is written in a style readble with java 7 what i have done is, altered the syntax into java 6 and then compile and it is 100% working. if you need, i can send you the jar.
