Re: [dspace-tech] Localhost

[Tony Brian Albers]

Hi,

Maya, HAProxy is an open-source High-Availability Load Balancer.

In short, this means that a HAProxy can handle incoming connections and 
then spread them out across i.e. multiple webservers behind it.

Re: [dspace-tech] Backup issues due to assetstore size

[Tony Brian Albers]

I hope I'm not being annoying, please bear with me. 

I'd like to explain how parallelism actually works in some(not all)
backup systems. See my answers below if you're interested. 

On Wed, 2020-08-12 at 09:14 -0400, Mark H. Wood wrote:

Right, it won't.

Yes, but that really depends on whether the CPU/MEM is actually used
properly.

Not necessarily. In general backup software scans the file system
looking for changes etc. before actually starting to stream data to the
backup storage. Often the scan and the save stream are handled by
single-threaded processes who traverses the file and folder structure,
and in this case where we have a large number of files, this will take
a large amount of time even though the disk might not be struggling at
all. But it will still be seen as a disk bottleneck.
By employing several scanning and streaming processes on the same file
system/disk, we can actually speed things up a lot. 

For instance, EMC NetWorker version > 8.1 actually can do parallel save
streams in one backup job on the same file system. I've used this a
number of times in situations like this and it helps a lot.

If they use tape drives and write directly to them, that might be true.
It's hard to utilize a tape drive's performance by saving directly to
it from a client. However, for sequential reads/writes tape is often
extremely fast and can easily outperform a RAID-5 storage system of the
same capacity. LTO-8 for example has a compressed write speed of
900MB/sec.
So if you have a fast temporary storage area on the backup system, you
can stream to that from the client and let the backup system dump it to
tape and save huge amounts of time.

It actually could. And that's probably a good place to start since it's
quite easy to check.

Not really. However one should consider using mountpoints in the
assetstore itself instead. That would make it easier to administrate.

Ehm, not following you here, Mark. 
What I think they want to achieve is a higher client parallelism. This
means that instead of one save stream running on one file system they
can have several savestreams running, one on each filesystem. If they
had backup storage performance issues that would not make sense.
So, going for higher parallelism by having several smaller file systems
makes sense.

Excellent point, can the DSpace server handle the extra network
traffic. Can the network?

I totally agree. For mostly static content you could do a full backup
once or twice a year combined with incremental and cumulative
incremental backups.

I'd suggest something like this:

.../dspace/assetstore/10  --mountpoint, filesystem10
.../dspace/assetstore/11  --mountpoint, filesystem11
.../dspace/assetstore/12  --mountpoint, filesystem12
 ...
.../dspace/assetstore/20  --mountpoint, filesystem20

That would do for the few houndreds of gigabytes you have. If you had >
10x that, I'd probably go for something like ZFS with replication and
snapshot backup

Good luck,

You probably need to change your tomcat settings, they're usually in
~tomcat/conf/server.xml  but it depends on your platform etc.

Re: [dspace-tech] Database connectivity Issue

[Tony Brian Albers]

What does getenforce say? This might be SELinux doing its job ;)

Check /var/log/audit/audit.log for stuff related to tomcat/catalina,
pgsql etc. 

Check the pgsql logs, they usually have some pointer as to where it
goes wrong. Also check the tomcat logs.

And an important thing:

The password stated in dspace.cfg or local.cfg must be entered as
follows:

db.password = un@b0mb3R?

make sure the spaces are there and be careful that your password
doesn't contain = or localized characters (german umlaut etc.)

also try to connect to pgsql directly from the CLI as the dspace user
like so:

[dspace@rigel config]$ psql -U dspace -W -d dspace
Password for user dspace: 
psql (9.5.14)
Type "help" for help.

[dspace-tech] Google groups issue accessing dspace-tech

[Tony Brian Albers]

Is anyone else having issues searchin/vieweing dspace-tech through
google groups?

If I search for something, I get:

"This group either doesn't exist, or you don't have permission to
access it. If you're sure this group exists, contact the Owner of the
group and ask them to give you access.
Reload"

Which is odd since I can receive and send mails using this account that
I'm sending from now.

Thanks Michael,

That looks doable, but pretty inconvenient -I'll have a closer look.

[dspace-tech] WORM submissions?

[Tony Brian Albers]

No, not about actual living beings, but Write Once Read Many.

Is it possible to make a collection only accept deposits and not let
the owner delete what he/she has deposited?

TIA

Re: [dspace-tech] cli way of changing dc.identifier.uri for all items?

[Tony Brian Albers]

Darn, I think I was celebrating too soon.

In our dspace/log, cocoon.log files have increased from around 
150mbytes/day to 3,5gigs/day.

Errors are like these:

  2018-01-11 13:45:46,947 INFO  org.apache.cocoon.i18n.XMLResourceBundle 
  - Bundle 
 
not loaded: Source URI not found

2018-01-11 13:45:46,828 ERROR cocoon.handled  - Unable to locate sitemap
 at  - 
file:///data/dspace/webapps/ROOT/sitemap.xmap:595
:56
 at  - 
file:///data/dspace/webapps/ROOT/sitemap.xmap:594:50


What we have done is:

changed hostname in dspace's local.cfg
changed dc.identifier.uri in postgres as per below.

Any ideas?

Re: [dspace-tech] cli way of changing dc.identifier.uri for all items?

Thanks Christian, but it doesn't work.

When I change the dc.identifier.uri field and import, it just says: "
There were no changes detected"

Really odd.

Any suggestions?

This says that you need to make sure you have the right database setup, 
AFAIR there's something about how to set up pgsql in the documentation.

Nope, you should point to whatever port your tomcat is running on, which 
I suppose is http://myserver.domain:8080/xmlui  -> 8080
Disregard that tomcat is not running https, that's what you're going to 
use httpd(apache) for.

Sorry for the late reply, I was off on weekend when you wrote me back :)

Dayne,

We proxy tomcat behind apache httpd to solve this exact issue. Our 
tomcat listens on port 8877.
If you want to try that, in short what you will need is to install httpd 
and set it up to run ssl. Then you can define a ssl-enabled virtualhost 
in apache that proxies your tomcat. Here is our httpd conf file for the 
virtualhost, I've added my comments in ### (with sensitive bits changed, 
but still in the right places):



# Default host when using NameVirtualHost

### ^ this creates a httpd server listening on port 80.
ServerAdmin helpd...@mydomain.edu
DocumentRoot /var/www/html
ServerName dspace-devel.mydomain.edu
ServerAlias dspace-devel

ErrorLog logs/dspace-devel.mydomain.edu-http-error_log
CustomLog logs/dspace-devel.mydomain.edu-http-access_log combined

ProxyPass / http://127.0.0.1:8877/  retry=10 connectiontimeout=5
### ^ this tells httpd to redirect it's / to localhost port 8877
timeout=300
ProxyPassReverse /  http://127.0.0.1:8877/  retry=10
### ^ this tells httpd that tomcat's url's should be rewritten to look 
###   like they're coming from httpd.
ProxyPreserveHost On
### ^ this tells httpd to keep the Host: information from the client and 
### pass it on to tomcat.




### ^ this creates a httpd server that listens on port 443.

###   live on the host.

### ^ this tells httpd to keep the Host: information from the client and

So much for the virtualhost/proxy setup.

To get httpd to use ssl, you will need to have mod_ssl installed, a 
ssl.conf file telling httpd how to use ssl and include files(mentioned 
above) with information about your certificates.



Here's our ssl.conf file:

Listen 443 https
SSLPassPhraseDialog exec:/usr/libexec/httpd-ssl-pass-dialog
SSLSessionCache shmcb:/run/httpd/sslcache(512000)
SSLSessionCacheTimeout  300
SSLRandomSeed startup file:/dev/urandom  256
SSLRandomSeed connect builtin
SSLCryptoDevice builtin
SSLStaplingCacheshmcb:/run/httpd/ocsp(128000)
# The default 'combined' format extended with SSL protocol and cipher 
logging
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" 
\"%{SSL_PROTOCOL}x\" \"%{SSL_CIPHER}x\"" combinedssl



This is our ssl.include file:

SSLEngine on
# modern configuration, tweak to your needs
SSLProtocol all -SSLv3 -TLSv1 -TLSv1.1
SSLCipherSuite 
ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256
SSLHonorCipherOrder on
SSLCompression  off
# OCSP Stapling, only in httpd 2.3.3 and later
SSLUseStapling  on
SSLStaplingResponderTimeout 5
SSLStaplingReturnResponderErrors off



And this is our ssl.include.star file:

SSLCertificateFile /etc/pki/tls/certs/star.mydomain.edu.crt
SSLCertificateChainFile /etc/pki/tls/certs/star.mydomain.edu.chain.crt
SSLCertificateKeyFile /etc/pki/tls/private/star.mydomain.edu.key






I hope this helps a bit. We're running CentOS so YMMV.

[dspace-tech] Getting /solr/search/select was not found

[Tony Brian Albers]

Hi guys,

I've set up a vanille DS 6.0 install, and when I try to use "browse by 
authors" I get the following error:

Expected mime type application/octet-stream but got text/html.   404 Not 
Found  Not Found The requested URL 
/solr/search/select was not found on this server. 


I'm unable to figure out where this is going wrong, tomcat runs 
everything on port 8080, and in catalina.out it says that solr has been 
deployed successfully.

Any help is appreciated.

TIA

Re: [dspace-tech] Shibboleth AND local users

[Tony Brian Albers]

Hi Terry,

Thanks, I think that will do. I had no idea it would give them the 
possibility to select which method to use.

Thanks Mark,

Escaping the #'s with \'s did the trick.

Thanks Monika,

I guess we'll just have to monitor the filesystem then.

[dspace-tech] Quotas

[Tony Brian Albers]

Hi guys and gals,

We're looking into deploying Dspace in a test environment, and I have a
couple of questions some of you might know the answers to:

1. Is it possible to limit the number of collections a single ePerson
can have?

2. Is it possible to set a quota on the amount of data a given
collection can contain? I.e. 20GB per collection?

Thanks,
