--- title: "July, 2019" date: 2019-07-01T12:13:51+03:00 author: "Alan Orth" tags: ["Notes"] --- ## 2019-07-01 - Create an "AfricaRice books and book chapters" collection on CGSpace for AfricaRice - Last month Sisay asked why the following "most popular" statistics link for a range of months in 2018 works for the CIAT community on DSpace Test, but not on CGSpace: - [DSpace Test](https://dspacetest.cgiar.org/handle/10568/35697/most-popular/item#simplefilter=custom&time_filter_end_date=01%2F12%2F2018) - [CGSpace](https://cgspace.cgiar.org/handle/10568/35697/most-popular/item#simplefilter=custom&time_filter_end_date=01%2F12%2F2018) - Abenet had another similar issue a few days ago when trying to find the stats for 2018 in the RTB community - If I change the parameters to 2019 I see stats, so I'm really thinking it has something to do with the sharded yearly Solr statistics cores - I checked the Solr admin UI and I see all Solr cores loaded, so I don't know what it could be - When I check the Atmire content and usage module it seems obvious that there is a problem with the old cores because I dont have anything before 2019-01 ![Atmire CUA 2018 stats missing](/cgspace-notes/2019/07/atmire-cua-2018-missing.png) - I don't see anyone logged in right now so I'm going to try to restart Tomcat and see if the stats are accessible after Solr comes back up - I decided to run all system updates on the server (linode18) and reboot it - After rebooting Tomcat came back up, but the the Solr statistics cores were not all loaded - The error is always (with a different core): ``` org.apache.solr.common.SolrException: Error CREATEing SolrCore 'statistics-2010': Unable to create core [statistics-2010] Caused by: Lock obtain timed out: NativeFSLock@/home/cgspace.cgiar.org/solr/statistics-2010/data/index/write.lock ``` - I restarted Tomcat *ten times* and it never worked... - I tried to stop Tomcat and delete the write locks: ``` # systemctl stop tomcat7 # find /dspace/solr/statistics* -iname "*.lock" -print -delete /dspace/solr/statistics/data/index/write.lock /dspace/solr/statistics-2010/data/index/write.lock /dspace/solr/statistics-2011/data/index/write.lock /dspace/solr/statistics-2012/data/index/write.lock /dspace/solr/statistics-2013/data/index/write.lock /dspace/solr/statistics-2014/data/index/write.lock /dspace/solr/statistics-2015/data/index/write.lock /dspace/solr/statistics-2016/data/index/write.lock /dspace/solr/statistics-2017/data/index/write.lock /dspace/solr/statistics-2018/data/index/write.lock # find /dspace/solr/statistics* -iname "*.lock" -print -delete # systemctl start tomcat7 ``` - But it still didn't work! - I stopped Tomcat, deleted the old locks, and will try to use the "simple" lock file type in `solr/statistics/conf/solrconfig.xml`: ``` ${solr.lock.type:simple} ``` - And after restarting Tomcat it still doesn't work - Now I'll try going back to "native" locking with `unlockAtStartup`: ``` true ``` - Now the cores seem to load, but I still see an error in the Solr Admin UI and I still can't access any stats before 2018 - I filed an [issue with Atmire](https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=685), so let's see if they can help - And since I'm annoyed and it's been a few months, I'm going to move the JVM heap settings that I've been testing on DSpace Test to CGSpace - The old ones were: ``` -Djava.awt.headless=true -Xms8192m -Xmx8192m -XX:+UseConcMarkSweepGC -Dfile.encoding=UTF-8 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=5400 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false ``` - And the new ones come from Solr 4.10.x's startup scripts: ``` -Djava.awt.headless=true -Xms8192m -Xmx8192m -Dfile.encoding=UTF-8 -XX:NewRatio=3 -XX:SurvivorRatio=4 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=8 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 -XX:+CMSScavengeBeforeRemark -XX:PretenureSizeThreshold=64m -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=50 -XX:CMSMaxAbortablePrecleanTime=6000 -XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=1337 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false ``` ## 2019-07-02 - Help upload twenty-seven posters from the 2019-05 Sharefair to CGSpace - Sisay had already done the SAFBundle so I did some minor corrections to and uploaded them to a temporary collection so I could check them in OpenRefine: ``` $ sed -i 's/CC-BY 4.0/CC-BY-4.0/' item_*/dublin_core.xml $ echo "10568/101992" >> item_*/collections $ dspace import -a -e me@cgiar.org -m 2019-07-02-Sharefair.map -s /tmp/Sharefair_mapped ``` - I noticed that all twenty-seven items had double dates like "2019-05||2019-05" so I fixed those, but the rest of the metadata looked good so I unmapped them from the temporary collection - Finish looking at the fifty-six AfricaRice items and upload them to CGSpace: ``` $ dspace import -a -e me@cgiar.org -m 2019-07-02-AfricaRice-11to73.map -s /tmp/SimpleArchiveFormat ``` - Peter pointed out that the Sharefair dates I fixed were not actually fixed - It seems there is a bug that causes DSpace to not detect changes if the values are the same like "2019-05||2019-05" and you try to remove one - To get it to work I had to change some of them to 2019-01, then remove them ## 2019-07-03 - Atmire responded about the [Solr issue](https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=685) and said they would be willing to help ## 2019-07-04 - Maria Garruccio sent me some new ORCID identifiers for Bioversity authors - I combined them with our existing list and then used my `resolve-orcids.py` script to update the names from ORCID.org: ``` $ cat dspace/config/controlled-vocabularies/cg-creator-id.xml /tmp/new-bioversity-orcids.txt | grep -oE '[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}' | sort -u > /tmp/2019-07-04-orcid-ids.txt $ ./resolve-orcids.py -i /tmp/2019-07-04-orcid-ids.txt -o 2019-07-04-orcid-names.txt -d ``` - Send and merge a pull request for the new ORCID identifiers ([#428](https://github.com/ilri/DSpace/pull/428)) - I created a CSV with some ORCID identifiers that I had seen change so I could update any existing ones in the databse: ``` cg.creator.id,correct "Marius Ekué: 0000-0002-5829-6321","Marius R.M. Ekué: 0000-0002-5829-6321" "Mwungu: 0000-0001-6181-8445","Chris Miyinzi Mwungu: 0000-0001-6181-8445" "Mwungu: 0000-0003-1658-287X","Chris Miyinzi Mwungu: 0000-0003-1658-287X" ``` - But when I ran `fix-metadata-values.py` I didn't see any changes: ``` $ ./fix-metadata-values.py -i 2019-07-04-update-orcids.csv -db dspace -u dspace -p 'fuuu' -f cg.creator.id -m 240 -t correct -d ``` ## 2019-07-06 - Send a reminder to Marie about my notes on the [CG Core v2 issue I created two weeks ago](https://github.com/AgriculturalSemantics/cg-core/issues/2) ## 2019-07-08 - Communicate with Atmire about the Solr statistics cores issue - I suspect we might need to get more disk space on DSpace Test so we can try to replicate the production environment more closely
