you don't have to create conf dir and schema.xml and solrconfig.xml
for each core separately. keep one instance dir where you have the
conf dir and its contents. pass the instanceDir when you create a new
core.
if you are using 1.3
in the solrconfig.xml , keep the datadir as follows
<dataDir>/data/solr/${core.name}</dataDir>
each core will automatically have a diffferent dataDir
