Re: [dspace-tech] DSpace 6: dewfault for CSV export value separator

Hi Ari,

bulkedit.cfg:
  


# The delimiter used to

However, it seems that default value is comma.

example (dc.contributor.author)
"Hannula, Mikale,Junttila, Matti,Duck, Donald"

Comma makes parsing of author names little bit tricky since
comma is also used as separator for firstname and lastname.
Is this right? Or have I misunderstood something?
  


I've just been able to reproduce this on a clean install of master.
This is a bug -- would you mind reporting this in Jira?

Re: [dspace-tech] clearing cache via java control panel

[Hardy Pottinger]

Hi, Jose, you mostly just need to delete the contents of the XMLUI
"workDir", which, as it happens, is a path you can set in your XMLUI
context. If you're using a Tomcat "context fragment" for XMLUI, you
probably have something like this:



Immediately after that, you can add a path to a "workDir":

workDir="/path/to/a/large/partition/dspaceWorkDir">

This workDir is used for Cocoon caches, as well as temp space for uploads.
We have a rather large partition set aside for this, to accomodate large
uploads. More background and links to lots more material here:

https://jira.duraspace.org/browse/DS-2359

DS-2359 is still open, BTW, and in need of a volunteer. Hint hint. :-)

Anyway, back to your question, here's a bash alias I have set up:

alias dspace.clearcache='sudo rm /pathto/dspaceWorkDir/cache-
dir/cocoon-ehcache.*'

You could easily adapt that to a cron job if you prefer.

Re: [dspace-tech] New installation of DSpace 5.5 with migrated data rendering pages after ~40 seconds

[Evelthon Prodromou]

The server has 32GB, postgresql on different box. I don't think it's a RAM 
issue.

I am wondering if it is a solr issue. I don't have tomcat running as user 
dspace. Instead, I change ownership in [dspace]/solr to dspace:tomcat and 
gave rw rights to both user and group.

Thanks

Re: [dspace-tech] New installation of DSpace 5.5 with migrated data rendering pages after ~40 seconds

[Alan Orth]

Hi,

>From your JAVA_OPTS I see you are allocating 4096 + 2048 megabytes of
RAM to Tomcat right from the start. How much memory does your server
have? This means your host must have AT LEAST 6GB of RAM just for
Tomcat, let alone PostgreSQL, Solr, and the rest of the operating
system. I wouldn't be surprised if you are encountering poor
performance due to swapping.

For reference, we run a fairly large DSpace instance with ~55,000
items and a decent amount of traffic and these are our JAVA_OPTS:

-Djava.awt.headless=true -Xms3072m -Xmx3072m -XX:MaxPermSize=256m
-XX:+UseConcMarkSweepGC -Dfile.encoding=UTF-8

Our server has 8GB of physical memory. Unless you know you need all
those JVM tweaks, I'd start by simplifying your JAVA_OPTS to something
more simple (for testing at least).

Regards,
