[Anitha Muppural (amuppura)]

Hi,

 

My name is Anitha Muppural and I work as a software Engineer at Cisco.

 

I have a solr/lucene 3.3.0 installed in I have a single core.

The sorl web application is deployed to websphere application Server 6.1
in a cluster JVM.(2)

I do delta imports programmatically using solrj and application listener
as per the instruction given here 
http://wiki.apache.org/solr/DataImportHandler#Scheduling

 

1.       Here is my sole config setting snippets

  <lockType>simple</lockType>

 

<maxFieldLength>10000</maxFieldLength>

    <writeLockTimeout>60000</writeLockTimeout>

    <commitLockTimeout>60000</commitLockTimeout>

 

 

<requestHandler name="/qis/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">

  <lst name="defaults">

    <str name="config">qiscore-data-config.xml</str>

  </lst>

  </requestHandler>

 

 

2.  Here is the code where I call the delta import inside a timer task

 

SolrServer server = new CommonsHttpSolrServer(solrCore);

            ModifiableSolrParams params = new ModifiableSolrParams();

            params.set("qt", "/qis/dataimport");

            params.set("command", "delta-import");          

            params.set("commit", "true");

            params.set("clean","false");

            params.set("optimize", "true");

            QueryResponse factSummaryResponse = server.query(params);

 

 

3. I have set the timer to run every hour.

Once  the delta import is done I get this error intermittently. I have
to restart the solr war for it to go away.

 

 

3.       I installed solr/lucene in our development environment and
deployed the solr war to WAS but with a single JVM. I do not see this
error there. Not even once.

4.       The difference between my development and stage environment is 

1.       Single to Multiple JVMs.

2.       The owner of the files created in the 2 environments differ in
the sense that development is set to my userd but stage is set a a
generic id.

 

 

I appreciate all your help.

 

Regards,

Anitha Muppural
