strange problem in the work of OrgUnit

[Alex B]

Dear colleagues, 

I have noticed a strange problem in the work of OrgUnit: when establishing more than 3000 relationships of one OrgUnit with different ITEMS, it is impossible to edit this OrgUnit and this OrgUnit loads very slowly on the page.

Is there any way to solve this problem? 

For example, increase the cache of node.js or java?

Please advise a solution.

Best regards,

Alex

Hi Alex,

I have encountered this problem too.
Seems related to the large number of relation schema metadata that is returned by the back-end and displayed in the edit metadata page.
Since they can't even be edited in the Metadata tab (only in the Relationships tab), I ended up creating a themed component for it and filtering them from this page.

Best regards,

A. U. Tavares

Dear Mr.Tavares,

thank you very much for your answer.

Could you please send more detailed information about it (creating a themed component for it and filtering them from this page)?

Best regards,

Alex

Hello,

To create the themed component you will need to check the doc: https://wiki.lyrasis.org/display/DSDOC7x/User+Interface+Customization

However, just today, I was having another problem with entities and created this issue, where you can check the answer by FelixNicol about tilted relations.

Using this solved my problem and also the one in the edit metadata tab.

You just need to change your relationships xml, adding either <tilted>LEFT</tilted> or <tilted>RIGHT</tilted>.

It works like this: if there is a relationship where usually the LEFT type has a bigger count (for example isPublicationOfOrgUnit) you add <tilted>LEFT</tilted>. Same idea for adding <tilted>RIGHT</tilted>.

After changing it, run again the initialize-entities script and do a full Solr indexing.

It will not crash in the edit tab and entities also will load faster in general.
