Suggestions for Appropriate Hardware

Hello everbody,

every now and then somebody rises questions regarding clock speed and disk space and the kind on this list
during planning for a new project or when going from development to production. I just skimmed through the
archived messages of the last year and found several requests for advice. Generally, the answer is "well,
it depends". All in all, threads on this topic remain quite superficial and people rarely come back with
this after some time. My conclusion is that it is really not much of an issue. What do you think?

Still then, as I am just planning for a new project, Id just like to raise this issue again, maybe in a slightly
different form than up to now. Maybe, we can find some aspects worth to remember and some questions to ask
the next time we as a community start to augment information on running instances. There have been already
several initiatives in this direction. I remember Valorie asking for information about new instances
two years ago; there is the DSpace instances list in the DSpace Wiki, some information is in the Fedora
Commons Examples and Solution Communities sections, but it none of these resources looks really
comprehensive for me. Lets keep that in mind.

About my new project, I can tell that I really have little information at hand for serious planning as of now,
so I wont come up with item counts, Gigabytes of storage requirements and so on here. What I do know already
is, that I will have a considerable amount of automatic processes running like mass ingest. There will be a
lot of scanned and OCRed, say *huge* PDFs to index, which will make me learn about the intricacies of
PDFBox, I suspect.

My focus is on building a really reliable setup, rather then tweaking performance. Though, performance,
such as database query performance is one aspect of reliability. Id like to hear your thoughts on either
architecture and specific components, rather then numbers. Here is a list of areas I ponder about.

Conventional setups seem to use two separate boxes, one for development, one for production, each running
the whohle software stack including database and JSP container. But what about a dedicated database
machine and Tomcat machine? 
Maybe with optimized mass storage for each purpose, id est smaller but faster expensive drives such as SAS

Help me please


Hi member
 
I'm using DSpace 1.3.2 which is not yet supported the script /update-handle-prefix/ on production. So I copied and pasted the script from 1.4.1. The script can be executed. But it is stopped after it has updated 12,004 records from more than hundred thousands records. It showed the error message: error relation "metadatavalue" does not exists.
How should I resolve this problem?
The handle URL is now usable. For example,
http://dspace2.car.chula.ac.th/dspace/handle/10639/137  or http://hdl.handle.net/10639/137
But the URI on the page is still displayed as "http://hdl.handle.net/123456789/137".
Is this because the update script was not completed successfully?
Thanks for your help.* *

In a terminal, do you get an output line with this command :
sudo netstat -npat|grep 8080

If the output is empty, a socket is not listening on this port for this 
host.
So you will have to check tomcat configuration.

Hope that help.

Adding bitstream formats for creative commons link

Hi.
 
Here <at> Exeter we are primarily using a Creative Commons license with an embedded link.
 
However, when viewed in every other browser than IE this just displays the html. I've boiled this down to the bitstream format, and its possible mainly to add it to the known formats per item, but is labour intensive.
 
I therefore wish to add it to 'known' bitstream formats, can anyone tell me the correct MIME type/format I should be using?
 
 
Cheers
 
Kevin

Re: Embargoes in 1.6

Hello Jason,

the liftdate is computed based on the embargo terms and the setter used.
At the moment there is one default embargo setter:

org.dspace.embargo.DefaultEmbargoSetter

which assumes the basic use case of the term being a date.

Which setter plugin to use is configured in the dspace.cfg:

# implementation of embargo setter plugin - replace with local 
implementation if applicable
plugin.single.org.dspace.embargo.EmbargoSetter = 
org.dspace.embargo.DefaultEmbargoSetter

In order to cover other use cases you got to write your own setter and 
use this instead of the default setter. You can do anything you like, 
for example using a set of timespans or depend the embargo time on the 
publication type. This is up to you.

Hope that helps

Claudia Jürgen

Announcing an updated DSpace Demo Server

All,

As you may or may not have been aware, in the past, we had an 
(unadvertised) DSpace Demonstration Repository available for live demos, 
testing, or just a place to "play" with the software before installing it.

We've now updated this DSpace Demonstration Repository to run DSpace 
1.6.0, and wish to advertise it as a place for anyone in the DSpace 
Community to use for demonstrations or as a sandbox to play with the 
latest software before installing it.

http://demo.dspace.org/

The above demonstration site provides a sample repository with all 
DSpace 1.6.0 new features enabled.  This demonstration site also 
includes all DSpace interfaces (JSPUI, XMLUI, SWORD, OAI-PMH, LNI), 
connected to the same underlying database (so items created via XMLUI 
will also appear under JSPUI).

You'll also find that (if you visit the JSPUI or XMLUI) there are 
pre-established user logins which allow you to browse/use the repository 
as any of the following roles:
* DSpace Administrator
* DSpace Community Administrator (manage a community, and all 
subcommunities, collections & items in it)
* DSpace Collection Administrator (manage a collection & items in it)
* DSpace Submitter (can only submit new items)

DuraSpace is committed to maintaining this demonstration repository for 
at least the next three months. After that period, we will reassess 
whether or not to keep this site up permanently, or whether to 
temporarily bring it down until the next release of DSpace. Of course, 
we are hopeful that this demonstration site will receive enough interest 
and usage to warrant continued availability. We'll let the DSpace 
Community know once any final decision has been made.

NOTE: We will not be actively monitoring the content or activities on 
this server. If you notice any problems or spam content, we ask that you 
either remove it (login as the sample Admin and delete it) or contact us 
via the DSpace Feedback Form.

In the meantime, feel free to play around in this DSpace Demonstration 
Repository.  Let us know what you think!

Tim

Re: Beginners Questions : Inabilty to access port 8080 on clients

Henry,

It is also possible to run Tomcat on port 80, rather than port 8080.

To run Tomcat on port 80 in Linux, you'd have to do the following:
(1) Change its port from 8080 to 80 in [tomcat]/conf/server.xml
(2) Compile the 'jsvc' tool that comes with Tomcat, and start Tomcat 
using 'jsvc'.  You need to start Tomcat using 'jsvc' because on Linux 
port 80 is a privileged port (only root can open it).

Here's a good reference on running Tomcat on port 80:
http://www.klawitter.de/tomcat80.html
(it says it's for Tomcat 5.x, but it should also work for Tomcat 6.x)

Also, look at the Tomcat Setup Docs for more information on compiling 
and using the 'jsvc' tool, which allows you to use port 80 on Linux:
http://tomcat.apache.org/tomcat-6.0-doc/setup.html#Unix%20daemon

It's also possible to setup an Apache web server on port 80, and have it 
forward to your Tomcat on port 8080 (using mod_jk or similar).  There 
are more notes on that setup on the following DSpace wiki pages:
http://wiki.dspace.org/index.php/DspaceOnStandardPorts
http://wiki.dspace.org/index.php/ModJk

Good luck!

Tim

Re: Adding bitstream formats for creative commons link

Hi Kevin,

See:

 - http://jira.dspace.org/jira/browse/DS-295

This has been fixed in DSpace 1.6.0. You may be able to use some of the information from the JIRA issue to fix
your current version if upgrading isn't an option right now.

Thanks,

DSpace 1.6 & Handle server

I'm having a puzzling problem. I am updating my system from DSpace 1.52 to 1.6. I'm running RHEL Server
release 5.3 (Tikanga).
My Java version is 1.5.0_20
My Tomcat version is 5.5.26 and I'm using mod_proxy_ajp to redirect to port 80.

I have upgraded correctly on my live server and everything works fine except handle (well, startup is a
little slower, but I'm not sure why that is.). Whenever I run the handle server and visit a handle, the whole
screen goes white and DSpace goes out in the weeds. Nothing works at that point. The whole system crashes.
What makes it worse is that I don't see any cause for it in any of the log files. Does anyone have any ideas what
causes this and how I might fix it?

I tested the upgrade pretty rigorously on a  Fedora 12 virtual machine with no problems prior to upgrading. 
Of course, handle was the one thing I didn't have a way to test.

Re: DSpace 1.6 & Handle server

Jason,
Check your hosts file comparing with your virtual machine.
I had same problem that you my handle server is not worked, the hostname had resolving a internal IP and we need to resolve a external IP (internet IP).
