Solr indexing problem

[Emmanuel Wilson]

Hello all...

I am using dspace 5.2 on debain server and i ave done database migration from 3.2 to 5.2.

After data migration pdf not coming in item window, It shows "INTERNAL SYSTEM ERROR"

Then i tried discovery tools;
/dspace/bin/dspace index-discovery -b
/dspace/bin/dspace filter-media
/dspace/bin/dspace index-discovery
/dspace/bin/dspace index-discovery -o

While using 3 rd command i got this error: Exception: Server refused connection at: http://localhost:8080/solr/search org.dspace.discovery.SearchServiceException: Server refused connection at: http://localhost:8080/solr/search

http://localhost:8080/jspui n xmlui working but http://localhost:8080/solr/search not working. I tried this to tomcat;

<Context path="/xmlui" docBase="/home/user/dspace/webapps/xmlui" allowLinking="true"/>
<Context path="/jspui" docBase="/home/user/dspace/webapps/jspui" allowLinking="true"/>
<Context path="/solr" docBase="/home/user/dspace/webapps/solr" allowLinking="true"/>
<Context path="/sword" docBase="/home/user/dspace/webapps/sword" allowLinking="true"/>
<Context path="/oai" docBase="/home/user/dspace/webapps/oai" allowLinking="true"/>

but still the problems exist...please help me to solve this.

Hi

Are you able to ping your solr server? Try using lynx browser on the server to browse to the solr server:

# lynx http://localhost:8080/solr/search

or try wget

# wget http://localhost:8080/solr/search

and see what error gets thrown to the screen.

I'm guessing localhost resolves because jspui and xmlui are accessible.

[Hayden Young]

What do you get when you try and access:

http://localhost:8080/solr/search/select?q=*:*

It is taking about a minute to reach on the home page of jspui.

xmlui is not accessible (It is returning a white screen)

I have upgraded to version 5.5 from version 4.2.

Your solr server looks to be running. what you've pasted below shows it is correctly querying but you have not indexed any records. If you have records in dspace run from the command line:

# /path/to/your/dspace/bin/dspace index-discovery

xmlui is not accessible (It is returning a white screen)

Have you deployed / configured xmlui in your tomcat?

Also, check both the Tomcat logs and the dspace logs (dspace logs under /path/to/your/dspace/log

Good luck


Hayden

Thanks for the reply.

Yes, I have records in dspace. In dsapce home I am able to see the communities, and name of author, articles written by them. However, I am not able to access pdf of the same. assetstore contains all pdf. on running command dsapce/bin/dspace index-discovery I received following error.

On second query regarding xmlui.

I have deployed the xmlui folder to tomcat/webapps/ successfully still i am failing to access it

tomcat logs file is attached herewith

[Hayden Young]

Is your port address correct? 8082? Not 8080?

[Dr. Pawan Agrawal]

Yes, it is 8082

[Hayden Young]

okay that's a very strange problem. Only other thing I can think of is to explicitly set the port on the solr.xml config.

Back up /path/to/dspace/solr/solr.xml

Open /path/to/dspace/solr/solr.xml

Change:

  <cores adminPath="/admin/cores">

to

  <cores adminPath="/admin/cores" hostPort="8082">

Restart tomcat and see if that fixes the connection refused issue (but the fact that you can get reqults back via http://localhost/solr/search/select?q=*:* makes me think that may do nothing).

Also from the look of your error logs it appears xmlui's not working due to a config issue in your xmlui.xml tomcat7 context.

[Dr. Pawan Agrawal]

Yes, in fact till now i am failing to get solution of the same on web. also tried to optimize the collection using command dspace index-discovery -o which sucessfully worked but dspace index-discovery is not working.

Today i tried to run the same command on the another installation but surprisingly that too showed the connection refused error...

I implemented your suggestions but that worsen the things. After that even jspui was giving homepage with errors....

Any way, many thanks for your extensive help. If you find any solution of the same, please do forward me....
