CGSpace Notes

2020-07-01

• A few users noticed that CGSpace wasn’t loading items today, item pages seem blank
  • I looked at the PostgreSQL locks but they don’t seem unusual
  • I guess this is the same “blank item page” issue that we had a few times in 2019 that we never solved
  • I restarted Tomcat and PostgreSQL and the issue was gone
• Since I was restarting Tomcat anyways I decided to redeploy the latest changes from the 5_x-prod branch and I added a note about COVID-19 items to the CGSpace frontpage at Peter’s request

2020-06-01

• I tried to run the AtomicStatisticsUpdateCLI CUA migration script on DSpace Test (linode26) again and it is still going very slowly and has tons of errors like I noticed yesterday
  • I sent Atmire the dspace.log from today and told them to log into the server to debug the process
• In other news, I checked the statistics API on DSpace 6 and it’s working
• I tried to build the OAI registry on the freshly migrated DSpace 6 on DSpace Test and I get an error:

2020-05-02

• Peter said that CTA is having problems submitting an item to CGSpace
  • Looking at the PostgreSQL stats it seems to be the same issue that Tezira was having last week, as I see the number of connections in ‘idle in transaction’ and ‘waiting for lock’ state are increasing again
  • I see that CGSpace (linode18) is still using PostgreSQL JDBC driver version 42.2.11, and there were some bugs related to transactions fixed in 42.2.12 (which I had updated in the Ansible playbooks, but not deployed yet)

2020-04-02

• Maria asked me to update Charles Staver’s ORCID iD in the submission template and on CGSpace, as his name was lower case before, and now he has corrected it
  • I updated the fifty-eight existing items on CGSpace
• Looking into the items Udana had asked about last week that were missing Altmetric donuts:
  • The first is still missing its DOI, so I added it and tweeted its handle (after a few hours there was a donut with score 222)
  • The second item now has a donut with score 2 since I tweeted its handle last week
  • The third item now has a donut with score 1 since I tweeted it last week
• On the same note, the one item Abenet pointed out last week now has a donut with score of 104 after I tweeted it last week

2020-03-02

• Update dspace-statistics-api for DSpace 6+ UUIDs
  • Tag version 1.2.0 on GitHub
• Test migrating legacy Solr statistics to UUIDs with the as-of-yet unreleased SolrUpgradePre6xStatistics.java
  • You need to download this into the DSpace 6.x source and compile it

2020-02-02

• Continue working on porting CGSpace’s DSpace 5 code to DSpace 6.3 that I started yesterday
  • Sign up for an account with MaxMind so I can get the GeoLite2-City.mmdb database
  • I still need to wire up the API credentials and cron job into the Ansible infrastructure playbooks
  • Fix some minor issues in the config and XMLUI themes, like removing Atmire stuff
  • The code finally builds and runs with a fresh install

2020-01-06

• Open a ticket with Atmire to request a quote for the upgrade to DSpace 6
• Last week Altmetric responded about the item that had a lower score than than its DOI
  • The score is now linked to the DOI
  • Another item that had the same problem in 2019 has now also linked to the score for its DOI
  • Another item that had the same problem in 2019 has also been fixed

2020-01-07

• Peter Ballantyne highlighted one more WLE item that is missing the Altmetric score that its DOI has
  • The DOI has a score of 259, but the Handle has no score at all
  • I tweeted the CGSpace repository link

2019-12-01

• Upgrade CGSpace (linode18) to Ubuntu 18.04:
  • Check any packages that have residual configs and purge them:
  • # dpkg -l | grep -E ‘^rc’ | awk ‘{print $2}’ | xargs dpkg -P
  • Make sure all packages are up to date and the package manager is up to date, then reboot:

# apt update && apt full-upgrade
# apt-get autoremove && apt-get autoclean
# dpkg -C
# reboot

2019-11-04

• Peter noticed that there were 5.2 million hits on CGSpace in 2019-10 according to the Atmire usage statistics
  • I looked in the nginx logs and see 4.6 million in the access logs, and 1.2 million in the API logs:

# zcat --force /var/log/nginx/*access.log.*.gz | grep -cE "[0-9]{1,2}/Oct/2019"
4671942
# zcat --force /var/log/nginx/{rest,oai,statistics}.log.*.gz | grep -cE "[0-9]{1,2}/Oct/2019"
1277694

• So 4.6 million from XMLUI and another 1.2 million from API requests
• Let’s see how many of the REST API requests were for bitstreams (because they are counted in Solr stats):

# zcat --force /var/log/nginx/rest.log.*.gz | grep -c -E "[0-9]{1,2}/Oct/2019"
1183456 
# zcat --force /var/log/nginx/rest.log.*.gz | grep -E "[0-9]{1,2}/Oct/2019" | grep -c -E "/rest/bitstreams"
