CGSpace Notes

2016-06-01

• Experimenting with IFPRI OAI (we want to harvest their publications)
• After reading the ContentDM documentation I found IFPRI’s OAI endpoint: http://ebrary.ifpri.org/oai/oai.php
• After reading the OAI documentation and testing with an OAI validator I found out how to get their publications
• This is their publications set: http://ebrary.ifpri.org/oai/oai.php?verb=ListRecords&from=2016-01-01&set=p15738coll2&metadataPrefix=oai_dc
• You can see the others by using the OAI ListSets verb: http://ebrary.ifpri.org/oai/oai.php?verb=ListSets
• Working on second phase of metadata migration, looks like this will work for moving CPWF-specific data in dc.identifier.fund to cg.identifier.cpwfproject and then the rest to dc.description.sponsorship

• Since yesterday there have been 10,000 REST errors and the site has been unstable again
• I have blocked access to the API now
• There are 3,000 IPs accessing the REST API in a 24-hour period!

# awk '{print $1}' /var/log/nginx/rest.log  | uniq | wc -l

• Looking at log file use on CGSpace and notice that we need to work on our cron setup a bit
• We are backing up all logs in the log folder, including useless stuff like solr, cocoon, handle-plugin, etc
• After running DSpace for over five years I’ve never needed to look in any other log file than dspace.log, leave alone one from last year!
• This will save us a few gigs of backup space we’re paying for on S3
• Also, I noticed the checker log has some errors we should pay attention to:

• Looking at issues with author authorities on CGSpace
• For some reason we still have the index-lucene-update cron job active on CGSpace, but I’m pretty sure we don’t need it as of the latest few versions of Atmire’s Listings and Reports module
• Reinstall my local (Mac OS X) DSpace stack with Tomcat 7, PostgreSQL 9.3, and Java JDK 1.7 to match environment on CGSpace server

• Looking at some DAGRIS data for Abenet Yabowork
• Lots of issues with spaces, newlines, etc causing the import to fail
• I noticed we have a very interesting list of countries on CGSpace:

• Not only are there 49,000 countries, we have some blanks (25)…
• Also, lots of things like “COTE D`LVOIRE” and “COTE D IVOIRE”

• Move ILRI collection 10568/12503 from 10568/27869 to 10568/27629 using the move_collections.sh script I wrote last year.
• I realized it is only necessary to clear the Cocoon cache after moving collections—rather than reindexing—as no metadata has changed, and therefore no search or browse indexes need to be updated.
• Update GitHub wiki for documentation of maintenance tasks.

• Replace lzop with xz in log compression cron jobs on DSpace Test—it uses less space:

# cd /home/dspacetest.cgiar.org/log
# ls -lh dspace.log.2015-11-18*
-rw-rw-r-- 1 tomcat7 tomcat7 2.0M Nov 18 23:59 dspace.log.2015-11-18
-rw-rw-r-- 1 tomcat7 tomcat7 387K Nov 18 23:59 dspace.log.2015-11-18.lzo
-rw-rw-r-- 1 tomcat7 tomcat7 169K Nov 18 23:59 dspace.log.2015-11-18.xz

• CGSpace went down
• Looks like DSpace exhausted its PostgreSQL connection pool
• Last week I had increased the limit from 30 to 60, which seemed to help, but now there are many more idle connections:

$ psql -c 'SELECT * from pg_stat_activity;' | grep idle | grep -c cgspace
