## 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

<!--more-->

- 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`:

```
<lockType>${solr.lock.type:simple}</lockType>
```

- And after restarting Tomcat it still doesn't work
- Now I'll try going back to "native" locking with `unlockAtStartup`:

```
<unlockOnStartup>true</unlockOnStartup>
```

- 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
```

- 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

- 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
