- CGSpace was down for five hours in the morning while I was sleeping
- While looking in the logs for errors, I see tons of warnings about Atmire MQM:

- I see thousands of them in the logs for the last few months, so it’s not related to the DSpace 5.5 upgrade
- I’ve raised a ticket with Atmire to ask
- Another worrying error from dspace.log is:

- The first error I see in dspace.log this morning is:
2016-12-02 03:00:46,656 ERROR org.dspace.authority.AuthorityValueFinder @ anonymous::Error while retrieving AuthorityValue from solr:query\colon; id\colon;"b0b541c1-ec15-48bf-9209-6dbe8e338cdc"
org.apache.solr.client.solrj.SolrServerException: Server refused connection at: http://localhost:8081/solr/authority
- Looking through DSpace’s solr log I see that about 20 seconds before this, there were a few 30+ KiB solr queries
- The last logs here right before Solr became unresponsive (and right after I restarted it five hours later) were:
2016-12-02 03:00:42,606 INFO org.apache.solr.core.SolrCore @ [statistics] webapp=/solr path=/select params={q=containerItem:72828+AND+type:0&shards=localhost:8081/solr/statistics-2010,localhost:8081/solr/statistics&fq=-isInternal:true&fq=-(author_mtdt:"CGIAR\+Institutional\+Learning\+and\+Change\+Initiative"++AND+subject_mtdt:"PARTNERSHIPS"+AND+subject_mtdt:"RESEARCH"+AND+subject_mtdt:"AGRICULTURE"+AND+subject_mtdt:"DEVELOPMENT"++AND+iso_mtdt:"en"+)&rows=0&wt=javabin&version=2} hits=0 status=0 QTime=19
2016-12-02 08:28:23,908 INFO org.apache.solr.servlet.SolrDispatchFilter @ SolrDispatchFilter.init()
- DSpace’s own Solr logs don’t give IP addresses, so I will have to enable Nginx’s logging of
/solr so I can see where this request came from
- I enabled logging of
/rest/ and I think I’ll leave it on for good
- Also, the disk is nearly full because of log file issues, so I’m running some compression on DSpace logs
- Normally these stay uncompressed for a month just in case we need to look at them, so now I’ve just compressed anything older than 2 weeks so we can get some disk space back

- I got a weird report from the CGSpace checksum checker this morning
- It says 732 bitstreams have potential issues, for example:
------------------------------------------------
Bitstream Id = 6
Process Start Date = Dec 4, 2016
Process End Date = Dec 4, 2016
Checksum Expected = a1d9eef5e2d85f50f67ce04d0329e96a
Checksum Calculated = a1d9eef5e2d85f50f67ce04d0329e96a
Result = Bitstream marked deleted in bitstream table
-----------------------------------------------
...
------------------------------------------------
Bitstream Id = 77581
Process Start Date = Dec 4, 2016
Process End Date = Dec 4, 2016
Checksum Expected = 9959301aa4ca808d00957dff88214e38
Checksum Calculated =
Result = The bitstream could not be found
-----------------------------------------------
- The first one seems ok, but I don’t know what to make of the second one…
- I had a look and there is indeed no file with the second checksum in the assetstore (ie, looking in
[dspace-dir]/assetstore/99/59/30/...)
- For what it’s worth, there is no item on DSpace Test or S3 backups with that checksum either…
- In other news, I’m looking at JVM settings from the Solr 4.10.2 release, from
bin/solr.in.sh:
# These GC settings have shown to work well for a number of common Solr workloads
GC_TUNE="-XX:-UseSuperWord \
-XX:NewRatio=3 \
-XX:SurvivorRatio=4 \
-XX:TargetSurvivorRatio=90 \

- I did some basic benchmarking on a local DSpace before and after the JVM settings above, but there wasn’t anything amazingly obvious
- I want to make the changes on DSpace Test and monitor the JVM heap graphs for a few days to see if they change the JVM GC patterns or anything (munin graphs)
- Spin up new CGSpace server on Linode
- I did a few traceroutes from Jordan and Kenya and it seems that Linode’s Frankfurt datacenter is a few less hops and perhaps less packet loss than the London one, so I put the new server in Frankfurt
- Do initial provisioning
- Atmire responded about the MQM warnings in the DSpace logs
- Apparently we need to change the batch edit consumers in
dspace/config/dspace.cfg:
event.consumer.batchedit.filters = Community|Collection+Create
- I haven’t tested it yet, but I created a pull request: #289
2016-12-06
- Some author authority corrections and name standardizations for Peter:
dspace=# update metadatavalue set authority='b041f2f4-19e7-4113-b774-0439baabd197', confidence=600 where metadata_field_id=3 and resource_type_id=2 and text_value like 'Mora Benard%';
UPDATE 11
dspace=# update metadatavalue set text_value = 'Hoek, Rein van der', authority='4d6cbce2-6fd5-4b43-9363-58d18e7952c9', confidence=600 where resource_type_id=2 and metadata_field_id=3 and text_value like 'Hoek, R%';
UPDATE 36
dspace=# update metadatavalue set text_value = 'Hoek, Rein van der', authority='4d6cbce2-6fd5-4b43-9363-58d18e7952c9', confidence=600 where resource_type_id=2 and metadata_field_id=3 and text_value like '%an der Hoek%' and text_value !~ '^.*W\.?$';
UPDATE 14
dspace=# update metadatavalue set authority='18349f29-61b1-44d7-ac60-89e55546e812', confidence=600 where resource_type_id=2 and metadata_field_id=3 and text_value like 'Thorne, P%';
UPDATE 42
dspace=# update metadatavalue set authority='0d8369bb-57f7-4b2f-92aa-af820b183aca', confidence=600 where resource_type_id=2 and metadata_field_id=3 and text_value like 'Thornton, P%';
UPDATE 360
dspace=# update metadatavalue set text_value='Grace, Delia', authority='0b4fcbc1-d930-4319-9b4d-ea1553cca70b', confidence=600 where resource_type_id=2 and metadata_field_id=3 and text_value like 'Grace, D%';
UPDATE 561
- Pay attention to the regex to prevent false positives in tricky cases with Dutch names!
- I will run these updates on DSpace Test and then force a Discovery reindex, and then run them on CGSpace next week
- More work on the KM4Dev Journal article
- In other news, it seems the batch edit patch is working, there are no more WARN errors in the logs and the batch edit seems to work
- I need to check the CGSpace logs to see if there are still errors there, and then deploy/monitor it there
- Paola from CCAFS mentioned she also has the “take task” bug on CGSpace
- Reading about
shared_buffers in PostgreSQL configuration (default is 128MB)
- Looks like we have ~5GB of memory used by caches on the test server (after OS and JVM heap!), so we might as well bump up the buffers for Postgres
- The docs say a good starting point for a dedicated server is 25% of the system RAM, and our server isn’t dedicated (also runs Solr, which can benefit from OS cache) so let’s try 1024MB
- In other news, the authority reindexing keeps crashing (I was manually running it after the author updates above):
$ time JAVA_OPTS="-Xms768m -Xmx768m -Dfile.encoding=UTF-8" /home/dspacetest.cgiar.org/bin/dspace index-authority

- For what it’s worth, after running the same SQL updates on my local test server,
index-authority runs and completes just fine
- I will have to test more
- Anyways, I noticed that some of the authority values I set actually have versions of author names we don’t want, ie “Grace, D.”
- For example, do a Solr query for “first_name:Grace” and look at the results
- Querying that ID shows the fields that need to be changed:
{
"responseHeader": {
"status": 0,
"QTime": 1,
"params": {
"q": "id:0b4fcbc1-d930-4319-9b4d-ea1553cca70b",
"indent": "true",
"wt": "json",
"_": "1481102189244"
}
},
"response": {
"numFound": 1,
"start": 0,
"docs": [
{
"id": "0b4fcbc1-d930-4319-9b4d-ea1553cca70b",
"field": "dc_contributor_author",
"value": "Grace, D.",
"deleted": false,
"creation_date": "2016-11-10T15:13:40.318Z",
"last_modified_date": "2016-11-10T15:13:40.318Z",
"authority_type": "person",
"first_name": "D.",
"last_name": "Grace"
}
]
}
}
- I think I can just update the
value, first_name, and last_name fields…
- The update syntax should be something like this, but I’m getting errors from Solr:
$ curl 'localhost:8081/solr/authority/update?commit=true&wt=json&indent=true' -H 'Content-type:application/json' -d '[{"id":"1","price":{"set":100}}]'
{
"responseHeader":{
"status":400,
"QTime":0},
"error":{
"msg":"Unexpected character '[' (code 91) in prolog; expected '<'\n at [row,col {unknown-source}]: [1,1]",
"code":400}}
- When I try using the XML format I get an error that the
updateLog needs to be configured for that core
- Maybe I can just remove the authority UUID from the records, run the indexing again so it creates a new one for each name variant, then match them correctly?
dspace=# update metadatavalue set authority=null, confidence=-1 where resource_type_id=2 and metadata_field_id=3 and text_value like 'Grace, D%';
UPDATE 561
- Then I’ll reindex discovery and authority and see how the authority Solr core looks
- After this, now there are authorities for some of the “Grace, D.” and “Grace, Delia” text_values in the database (the first version is actually the same authority that already exists in the core, so it was just added back to some text_values, but the second one is new):
$ curl 'localhost:8081/solr/authority/select?q=id%3A18ea1525-2513-430a-8817-a834cd733fbc&wt=json&indent=true'
{
"responseHeader":{
"status":0,
"QTime":0,
"params":{
"q":"id:18ea1525-2513-430a-8817-a834cd733fbc",
"indent":"true",
"wt":"json"}},
"response":{"numFound":1,"start":0,"docs":[
{
"id":"18ea1525-2513-430a-8817-a834cd733fbc",
"field":"dc_contributor_author",
"value":"Grace, Delia",
"deleted":false,
"creation_date":"2016-12-07T10:54:34.356Z",
"last_modified_date":"2016-12-07T10:54:34.356Z",
"authority_type":"person",
"first_name":"Delia",
"last_name":"Grace"}]
}}
- So now I could set them all to this ID and the name would be ok, but there has to be a better way!
- In this case it seems that since there were also two different IDs in the original database, I just picked the wrong one!
- Better to use:
dspace#= update metadatavalue set text_value='Grace, Delia', authority='bfa61d7c-7583-4175-991c-2e7315000f0c', confidence=600 where resource_type_id=2 and metadata_field_id=3 and text_value like 'Grace, D%';
- This proves that unifying author name varieties in authorities is easy, but fixing the name in the authority is tricky!
- Perhaps another way is to just add our own UUID to the authority field for the text_value we like, then re-index authority so they get synced from PostgreSQL to Solr, then set the other text_values to use that authority ID
- Deploy MQM WARN fix on CGSpace (#289)
- Deploy “take task” hack/fix on CGSpace (#290)
- I ran the following author corrections and then reindexed discovery:
update metadatavalue set authority='b041f2f4-19e7-4113-b774-0439baabd197', confidence=600 where metadata_field_id=3 and resource_type_id=2 and text_value like 'Mora Benard%';
