[dspace-tech] DSpace error harvesting

[diegoaraujo]

Hello everyone

We're getting sporadic errors that prevent the complete harvesting 
(import). Usually for large repositories in long processes (+ 100k items)

If increase the servers.xml  parameters maxThreads, 
minSpareThreads e maxSpareThreads the error error appears faster. The same 
occurs with default values and they were tested environments with java 7 or 
8 and Tomcat 7.x or 8.x

Could you give us an idea of what might be happening in our environment?

[dspace-tech] Problem with finding authors

[MaX Verner]

Good day.

When adding an author to a collection (for example Washin), the search 
works very slowly and as a result does not give results.
If I'm looking for Washington. As a result, the author is found, but very 
slowly (about 1 minute).

Someone could help? Thank you in advance.

Hi Jose,

I struggled with this, too - I think it is not documented, but you can 
append the parameter "limit", e.g.


/rest/communities?limit=500

should return 500 entries (I only tried the "communities" and "collections" 
endpoints). There is also a parameter "offset", I think.

Have a look into

When I do RESTapi/items on a browser, I only see a small portion of
items on the display. How do I get a full list of all the items in our

Re: [dspace-tech] how to make dspace run on port 80 rather than 8080

[Shaun donovan]

Hi Harry.

Last time I ran it on Windows was a long time ago, but the process must 
still be the same. In the directory where Tomcat is installed (depends 
on how you installed it), there will be a conf folder, and inside that 
folder will be a server.xml file. If you edit this file and find the 
setting that starts with ''8080 to 80. You will also need to ensure that your firewall allows 
connection in on port 80.


Here is a short tutorial on it as well: 
http://www.ntu.edu.sg/home/ehchua/programming/howto/tomcat_howto.html


Hope that helps.

Shaun.
