You can't rebuild just XMLUI. (I hope someone will prove me wrong, but I
doubt it).

XMLUI has dependencies like dspace-api and dspace-services and the
dependencies are not always obvious.


You can, however, exclude some modules from building. It would look
something loke this:

mvn package -P \!dspace-sword,\!dspace-swordv2,\!dspace-rdf,\!dspace-rest

Figuring out which modules you can afford to exclude will need some
experimenting because of the mentioned dependencies.

Try running a discovery reindex with the -b flag. The exact command to use
will depend on your version of DSpace.

I can confirm that leaking transactions are a long-term unsolved issue
since DSpace 3. On the postgres side, you will see that most of the
connections are "idle in transaction". It's probably a tricky DSpace
context closing issue (or several of them).

The workaround is to restart either Tomcat or DSpace.

[dspace-tech] Rebuilding DSpace

[Donald Bynum]

I am running DSpace 5.5 with XMLUI and Mirage.  This is likely trivial, 
however - When I rebuild DSpace, the only webapp I am customizing is 
XMLUI.  My build script (the out of the box script) rebuilds all webapps.  
I only want to rebuild XMLUI.  I don't want to "guess" at what to remove 
from the build scripts.  Could someone please advise me on what a build 
script would look like for just rebuilding XMLUI.

Regards,

Don.

[dspace-tech] Problem with Thumbnails loading

[George Kozak]

Hi,
I am running DSpace 5.5, XMLUI, MIrage2 modified theme.  We have been
running for a long time, and just this weekend we started having PostGres
and java problems.  I upped the memory allocated to tomcat (Xms4096;
Xmx8192; Xmn2048) and increased the number of the max db connections (from
100 to 500), but I am still having problems.  I get the PostGres error in
the dspace log:
" FATAL: remaining connection slots are reserved for non-replication
superuser connections"
Any suggestions would be appreciated.

[dspace-tech] Collection items disappeared

[Massimiliano CILURZO]

Dear all,
 We have a  problem with our DSAPCE, after that tomcat went down today. 
we have restarted it. But now if we go in our collections we can't see any 
items we can search it but it seems that items in the collections are 
disappeared.
Thanks

Re: [dspace-tech] What does the ID search operator do ?

[helix84]

Hi Monika,

as you can see by searching for "Not ID" [1] it matches on the exact
internal authority identifier if you're using authority (authority is
useful to distinguish two authors with the same name). If you look at
the metadatavalue table [2], it's the "authority" column there. Also
the document ID in Solr "authority" core, if you're using the
SolrAuthority implementation.

Re: [dspace-tech] Dspace Hosting

[helix84]

The error in your screenshot is quite clear - Solr can't create a directory
it needs. It doesn't have filesystem permission to do so.

You have to make sure that your DSpace installation is owned by the same
user you use to run Tomcat.

Example (where tomcat7 is your user and group to run Tomcat):
chown -R tomcat7:tomcat7 /dspace

Re: [dspace-tech] Export and reload

[helix84]

Hi Jeff,

I'm not sure I fully understood your problem. I understand you want to
keep handles, which you definitely should. I don't understand why
there would be any handle conflicts on an upgrade.

To answer your question - no, changing provenance will not pose a
problem for DSpace as this field is not machine-readable.

Anyway, why do you need to change provenance? By default, it's only
visible to administrators, so you'd be removing information that could
be potentially helpful to you in the future.

Re: [dspace-tech] Implimentation of login

[helix84]

I also recommend you reconsider deploying LDAP, it is appropriate in a
college setting for more than just DSpace.

If you want to do this the hard way, then I suggest you use row-level
locking [1] on the specific row of the "eperson" table [2] that you
need to protect. Please note that this feature is only available as of
the latest release of Postgres - 9.5.

Alternatively, you can change the DSpace source code to disallow
password changes for the password authentication method. If you just
change it to false, it will be effective for all users. You should
only set it to false for the specific username you want to prevent
from changing their password.

As the first paragraph there mentions, you can see *all* the available
metadata fields ("variables") in the "xoai" format. Example:

http://demo.dspace.org/oai/request?verb=GetRecord=xoai=oai:demo.dspace.org:10673/7

>From there, you can transform it into any other format via XSLT:
