Multiple Solr-instance share same solr.home
Hi, Is it possible to have two solr instances share the same solr.home? I've two Solr instances running on the same box and I was wondering if I can configure them to have the same solr.home. I tried it, but looks like the second instance overwrites the first one's value in the solr.xml (I'm using multicore for both instances). This is just for convenience so I don't have to manage multiple solr index directory locations - I can have all the indexes written into the same location and do the clean up from one place itself. If this is not supported then it's not a big deal. Thanks, -vivek

Vivek - no, unless you want trouble - only 1 writer can write to a specific index at a time.

Re: Multiple Solr-instance share same solr.home
Both Solr instances will be writing to separate indexes, but can they share the same solr.home? So, here is what I want, 1) solr.home = solr/multicore 2) There is a single solr.xml under multicore directory 3) Each instance would use the same solr.xml, which will have entries for multiple cores 4) Each instance will write to different core at a time - so one index will be written by only one writer at a time. not sure if this is a supported configuration.

Re: Multiple Solr-instance share same solr.home
as long as you make sure there are never two applications writing to the same index, you *should* be ok. But tread carefully...

I think this should work, but it surely sounds unusual... which always makes one wonder why.
