shareSchema="true" - location of schema.xml?

[Satish Talim]

I have 1000's of cores and to reduce the cost of loading unloading
schema.xml, I have my solr.xml as mentioned here -
http://wiki.apache.org/solr/CoreAdmin
namely:

<solr>
  <cores adminPath="/admin/cores" shareSchema="true">
    ...
  </cores>
</solr>

However, I am not sure where to keep the common schema.xml file? In which
case, do I need the schema.xml in the conf folder of each and every core?

My folder structure is:

     multicore (contains solr.xml)
        |_ core0
             |_ conf
             |    |_ schema.xml
             |    |_ solrconfig.xml
             |    |_ other files
           core1
             |_ conf
             |    |_ schema.xml
             |    |_ solrconfig.xml
             |    |_ other files
             |
           exampledocs (contains 1000's of .csv files and post.jar)

You don't say which platform you are on but have you tried links (with ln on linux/unix) ?

Would it work to just (relative) path the schema
file for your cores with the "schema" parameter?

I am experimenting Solr on Windows, for now.

I have 300 cores so I feel your pain :-)

What we do is use a relative path for the file.  It works if you use ../../common/schema.xml for each core, then just create a common directory off your solr home and put your schema file there.

I found this works great with solrconfig.xml and all of it's dependencies as well.

Another choice is to look at the sharedLib parameter, which adds some directory to your classpath.  I played with this for a little bit and couldn't get it working, so I went with the relative path solution.
