How have you managed to deploy the Site under "ITdbpedia"? Have you
manually changed the configuration after installing the Bundle?
While this might work (if you correctly adapt the configuration for
the ReferencedSite, Cache and SolrYard those will still override the
configurations of the default DBpedia index simple because the OSGI
config files provided by the bundle (2) do have the same name as the
default dbpedia index config files.

This usually happens if the SolrYard "ITdbpediaIndex" is configured
for a SolrCore that is not available. Are you sure that a SolrCore
with the name configured for the "Solr Index/Core" property of the
ITdbpediaIndex SolrYard is available?
Assuming you have configured {solr-core} you will need to (a) extract
the "dbpedia.solrindex.zip" file (b) rename the root folder from
"dbpedia" to "{solr-core}" (c) re-create the ZIP file (d) rename it to
"{solr-core}.solrindex.tzp".

The intended way to change the name of a ReferencedSite created by the
Entityhub Indexing Tool is to change the value of the "name" property
within the
"./indexing/config/indexing.properties" file.
In case of the dbpedia Indexing tool you need to change the
"indexingDestination" from
indexingDestination=org.apache.stanbol.entityhub.indexing.destination.solryard.SolrYardIndexingDestination,solrConf,boosts:fieldboosts
to
indexingDestination=org.apache.stanbol.entityhub.indexing.destination.solryard.SolrYardIndexingDestination,solrConf:dbpedia,boosts:fieldboosts
NOTE the change from "solrConf" to "solrConf:dbpedia". This is
necessary to tell the SolrYardIndexingDestination component that the
SolrCore configuration is called "dbpedia". By default it assumes that
the name is equals to the value of the "name" property.
Before re-indexing you should also delete the "./indexing/destination"
folder as otherwise you will have both the data of the old index
(dbpedia) and the new one {name} in the destination folder.

If you want to create an "installable bundle" without reindexing the
data you can follow the following steps:
0. if there are still files in the indexing/resources/rdfdata folder
remove them as they are already imported into the Jena TDB store
(indexing/resources/tdb)
1. make the changes as described above
2. delete the indexing/destination folder (make sure to NOT delete the
indexing/dist folder!)
3. replace the indexing/resource/incoming_links.txt file with an empty
one (make sure to not delete the current version)
4. start the indexing (this should now complete in some seconds as no
entities are indexed.
After that you should see in the indexing/dist folder 4 files
a. "dbpedia.solrindex.zip"
b. "{name}.solrindex.zip" (this is empty - delete it)
c. "org.apache.stanbol.data.site.dbpedia-{version}.jar" (the old
bundle - delete it)
d. "org.apache.stanbol.data.site.{name}-{version}.jar (the new bundle)
(d) is the patched Bundle that you can use to install your custom
dbpedia index without overriding the default one. However to use this
bundle you need still modify the "dbpedia.solrindex.zip" as described
above: (a) extract the "dbpedia.solrindex.zip" file (b) rename the
root folder from "dbpedia" to "{name}" (c) re-create the ZIP file (d)
renme it to "{name}.solrindex.zip".
I admit that those steps are complex, but they might save you the time
needed to re-create your index.
best
Rupert
