  • Peter gave feedback on the dc.rights proof of concept that I had sent him last week
  • We don’t need to distinguish between internal and external works, so that makes it just a simple list
  • Yesterday I figured out how to monitor DSpace sessions using JMX
  • I copied the logic in the jmx_tomcat_dbpools provided by Ubuntu’s munin-plugins-java package and used the stuff I discovered about JMX in 2018-01

  • Uptime Robot noticed that CGSpace went down and up a few times last night, for a few minutes each time
  • I didn’t get any load alerts from Linode and the REST and XMLUI logs don’t show anything out of the ordinary
  • The nginx logs show HTTP 200s until 02/Jan/2018:11:27:17 +0000 when Uptime Robot got an HTTP 500
  • In dspace.log around that time I see many errors like “Client closed the connection before file download was complete”
  • And just before that I see this:
Caused by: org.apache.tomcat.jdbc.pool.PoolExhaustedException: [http-bio-127.0.0.1-8443-exec-980] Timeout: Pool empty. Unable to fetch a connection in 5 seconds, none available[size:50; busy:50; idle:0; lastwait:5000].
  • Ah hah! So the pool was actually empty!
  • I need to increase that, let’s try to bump it up from 50 to 75
  • After that one client got an HTTP 499 but then the rest were HTTP 200, so I don’t know what the hell Uptime Robot saw
  • I notice this error quite a few times in dspace.log:
2018-01-02 01:21:19,137 ERROR org.dspace.app.xmlui.aspect.discovery.SidebarFacetsTransformer @ Error while searching for sidebar facets
org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'dateIssued_keyword:[1976+TO+1979]': Encountered " "]" "] "" at line 1, column 32.
  • And there are many of these errors every day for the past month:

  • Generate list of authors on CGSpace for Peter to go through and correct:
dspace=# \copy (select distinct text_value, count(*) as count from metadatavalue where metadata_field_id = (select metadata_field_id from metadatafieldregistry where element = 'contributor' and qualifier = 'author') AND resource_type_id = 2 group by text_value order by count desc) to /tmp/authors.csv with csv;
