Solr heap memory

Hi All We are using solr cloud 8.8.1. We are frequently seeing memory and CPU reaching 100%. Can someone please suggest ideal way to define java heap memory. Server memory is 62Gb, swap-7Gb Currently we have defined as below in solr in.sh SOLR_HEAP= 46000m SOLR_JAVA_MEMORY= Xms:1024m, Xmx: 70

Re: Solr heap memory

Try setting you xms and xmx to the same value. You have enough memory to go pretty high so I’d try 31gb, 31000mg. Do not go over 31. Also disable swap on the server Let me know if it helps > On Aug 29, 2021, at 3:56 AM, HariBabu kuruva > wrote: > > Hi All > > We are using solr cloud 8.8.1

Re: Solr heap memory

Thanks for your reply Dave. Is it required to define both the parameters SOLR_HEAP and SOLR_JAVA_MEM. or can i comment SOLR_HEAP and only define SOLR_JAVA_MEM. Also what highest value of Xmx value i can go if i receive OOM with 31gb. I have only solr running on that node. And could you please l

Re: Solr heap memory

Yes. Don’t set those memory restrictions, just xms and xmx, both to 31 gigs. Java has problems past that line and will make the gc go into a bad loop. I can send you a link as to why https://community.datastax.com/questions/3661/why-is-a-32-gb-heap-allocation-not-recommended.html But this is a

Sort results based on alpha at first

Hi, We need to sort the results based on alphabetic followed by numeric. Something like below Current results order: 1test 2test 3test Abctext Bbctext Cbctext Expected results order: Abctext Bbctext Cbctext 1test 2test 3test Please help me to achieve the result ordering

Re: Sort results based on alpha at first

Hi Thamizh You can add a field to the index that acts as a "sortable flag" with e.g. 0 for alpha, 1 for numerical, and 2 for other first character. Then you can sort on both fields, listing the "flag" field first. Thomas Op zo 29 aug. 2021 20:09 schreef : > Hi, > > > > We need to sort the resul
