Item Counters for Communities and Collections not working well

[Caty]

Hi,

The setting:

webui.strengths.show = true

is not updating the item counter for collections and communitiesin DSpace 7.6/DSpace 7.6.1.

Not even dspace index-discovery -b is not updating the item counters.

Only tomcat restart in updating the counters.

Seetting webui.strengths.cache to false failes DSpace to load collections and communities

The same is on demo dspace:

The collection collection1_test  in this community

 https://demo.dspace.org/communities/dd23e4d3-92fa-460f-a6a9-b612fef7aa79

has 1 item , but displays counter 0:

collection1_test  (0 )

It is not updated in real time, not even hours after adding the item.

In DSpace 6 it was working very well, the counter was updated within seconds after adding items.

So the behaviour of item counters is as described here:

https://github.com/DSpace/dspace-angular/issues/1787

That was the first thing I thought about. I ran dspace index-discovery -b, then re-loaded Solr core but it did not help. The numbers still don't add up.

Also, enabling web.strengths.cache to false causes collections to freak out. What logs should I examine? Not much in dspace logs, not much in Catalina.out 

*******************

We really need this feature..

Could you give a solution, please?

Thank you very much,

Caty

Hi, Is anyone using item counters for Communities and Collections? Are they working well?

Thank you,

Caty

Hi Caty,

It depends on how you define "working well". I just don't expect immediate updates. Not sure how long it takes, but AFAIK the next day the numbers look good. That's well enough for me )

WBR,

Andrew

Hi Andrew,

Thank you for your answer.

My expectation was that item counters have the same behaviour as in version 6, that means immediate update of counters.

In tests I made on dome.dspace.org item counters did not updated immediately, the next day or not even the second day after creating new items, although they appeared immediately in Recent Submissions.

Same on my dspace 7 implementation, where I observed only tomcat restart updated them.

Kind regards,

Caty

Hi Caty

workinq well has many meanings   😂  ... 

 the main factors are  a)  the item-counter is no instantly updated as Andrew points out     b)    any item can have different access  policies.

The latter  means that the item-counter reflects the anonymous´user view of the repository,  (our experiences seems to indicate that, I have not checked the code)  , so expect large discrpancies if the number of restricted items, o even collections, is noticiable

Best

Emilio

Hi Emilio,

I added yesterday an item in the collection https://demo.dspace.org/collections/2dc46bf8-772f-4c44-8abd-a4514c23da96 (Home/Comunidade de teste/Coleção de teste)

This collections has: READ Anonymous ,DEFAULT_ITEM_READ Anonymous, DEFAULT_BITSTREAM_READ Anonymous
and the parent community (Comunidade de teste): READ Anonymous

This collection has 2 items (one existent and one added by me), but it shows collection item counter 1:  "Coleção de teste (1)"

Best regards,
Caty

[Andrew K]

It shows eactly 2 items now...

Hi,

The item counter for collection  https://demo.dspace.org/collections/48d86c8d-4a35-4c79-b7b7-26a41995cc1a

(READ/DEFAULT_ITEM_READ/DEFAULT_BITSTREAM_READ) with 2 items

is stiil 1 :  DDD  (1)  , although the second item has been submitted on the 5th of March, 4 days ago.

Best regards,

Caty

We are seeing the same problematic behavior in our production installation. Incorrect inaccurate item counts, even on publicly accessible collections & items, even days after the most recent submission.

Forgot to add that disabling the cache (setting `webui.strengths.cache=false`) results in "Error fetching collection" and "error.top-level-communities". No communities or collections will load.

From the console & error logs: java.lang.NullPointerException: Cannot invoke "org.dspace.core.DBConnection.getSession()" because the return value of "org.dspace.core.Context.getDBConnection()" is null

Update: restarting Tomcat updates the item counts to the correct number.
