[dspace-tech] Set up Dspace 7.2

[LSBU]

Hello, I would like to know some parameters for my Dspace 7.2: 
1- How to create a user group on the terminal ?
2- how to add a user on the terminal ?
3- how to import users from the terminal ?
4- what are the services to start after restarting the server to make 
Dspace functional ?
5- how to automate these services so that they start automatically at 
server startup ?
6- how to improve response times if we perform a search from the portal.5 ?
7- What are the data and configuration files to backup so that in case of a 
problem, we can restore our database?

Re: [dspace-tech] Disk partitioning for DSpace 7

"Optimum" will be strongly dependent on (a) your OS and (b) how much
you are storing in your repository.

That seems sensible.

I don't think anyone is going to have a "best way" for you, but here's
what I've done.

o  I like to keep the Solr cores and the database each on its own
   volume.  That way /var can fill up with log files and not stop
   DSpace.  (These days, the DBMS is on a separate host, and I'd like
   to move Solr to yet another since they tend to become busy at the
   same time.)

o  I invented a configuration parameter 'dspace.var' and use it
   throughout the configuration, wherever DSpace is configured to
   store volatile files such as exported materials and the assetstore.
   Code and configuration are installed on the /opt volume and the
   rest is mounted on /var/lib/dspace.  This last is again a separate
   volume.

I've installed Monit to keep Tomcat, Solr and PostgreSQL running,
monitor availability, restart anything that gets wedged, and email me
if there's anything it can't handle.  I also have the critical storage
volumes monitored in case one comes close to filling up.

I strongly recommend using a logical volume layer on top of a very
simple physical partitioning scheme, so that you can add physical
volumes online and portion them out as needed when logical volumes
fill up.  Usually I'll set up physical partitions "/" and "/boot", and
make all the rest a single LVM PV partition, leaving some uncommitted
storage in case I need to expand an LV more quickly than our corporate
virtual-machine infrastructure can respond to my request.  If I need
to add physical storage, I can join it to the existing volume group,
add slices to LVs as needed, and expand the LVs' filesystems into the
new extents, all without interrupting service.  (You don't need to
understand *all* of that on Day 1, but getting the basics done at
installation will make life so much nicer as the repository grows.)

I need to say that usually on a new host I'll take a wild guess about
how much storage will be needed for each of these various functions,
then adjust when I see how the system is really operating.  Some of my
guesses have been quite over-generous.  It's much harder to shrink a
volume than to expand one, even on LVM.  These days I'd probably
request just as much physical storage, but leave more of it
uncommitted and watch growth more closely.

In the end, only a running system can tell you *precisely* what it
needs to function adequately and reliably.  Provide yourself with good
system management tools and the ability to readily add capacity if you
need it.  Always give your systems a thorough inspection for capacity
as annual budget time approaches.

[dspace-tech] Re: index-authority java.lang.NullPointerException after upgrade 6.x to 7.4

[amtuan...@gmail.com]

I was able to run the index-authority command successfully now with DSpace 
7.5 and some changes to ORCID authority section in my local.cfg in case 
someone runs into the same issue.

# Configuration settings for ORCID based authority control

plugin.named.org.dspace.content.authority.ChoiceAuthority = \

org.dspace.content.authority.SolrAuthority = SolrAuthorAuthority

solr.authority.server=${solr.server}/authority

authority.controlled.dc.contributor.author = true

authority.author.indexer.field.1=dc.contributor.author
