I have a home-grown solution. Set up two identical servers (server1 and 2) and install DSpace on both of them. Server 1 is the main DSpace instance, server 2 the secondary. Make sure that both servers can talk to each without having to log in. Once that's working, do the following. Enter data on server 1 only. At the end of the day (or whenever) run a script that does this: 1. On server 1, make a database dump of the Postgres database and store it in a directory called backups. Add something like this code to your cron job: > /usr/bin/pg_dump --host "localhost" --port "5432" --username "postgres" > --role "postgres" --no-password dspace | gzip > "/home/user/backups/$(date > +%Y%m%d)_dspace.sql.gz"
2. From server 2 run rsync to copy the backed up database and all new bitstreams from server 1 to 2. > rsync -av server1:/home/user/backups /dspace (database) > rsync -av server1:/dspace/assetstore /dspace/assetstore/ (bitstreams) 3. Uncompress the backed up database. > gunzip $(date +%Y%m%d)_dspace.sql.gz 4. Stop the current dspace database on server 2. > psql -U postgres --no-password -c "select > pg_terminate_backend(pg_stat_activity.pid) from pg_stat_activity where > datname='dspace'" 5. Delete the dspace database. > dropdb -U postgres dspace 7. Create a new dspace database. > createdb -U postgres --owner=dspace --encoding=UNICODE dspace 8. Import the database into the database server running on server 2. psql -U postgres --no-password dspace < $(date +%Y%m%d)_dspace.sql -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Monday, January 19, 2015 4:20 AM To: [email protected] Subject: DSpace-tech Digest, Vol 105, Issue 41 Send DSpace-tech mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit https://lists.sourceforge.net/lists/listinfo/dspace-tech or, via email, send a message with subject or body 'help' to [email protected] You can reach the person managing the list at [email protected] When replying, please edit your Subject line so it is more specific than "Re: Contents of DSpace-tech digest..."

It happens most at the stage of file upload but it also occurs at the stage of "I grant the license". Any clue to resolve this issue?

Our server got shutdown due to un anticipated power cut and backup failure in an abrupt mode. Now we are not able to see following at bottom of Item page ("File in this Item" section): File Description Size Format View/Open Button Except for "View/Open Button" rest of labels are appearing but value for each of parameter along with "View/Open Button" is not appearing. You are requested to suggest, what corrections should be done for restoring the earlier state of solution. We are using DSpace on RHEL OS. Thanks in advance.

See: http://scholar.sun.ac.za Here is the faculty palette: http://wiki.lib.sun.ac.za/index.php/SUNScholar/Theme/Color_Palette Attached is my "xmlui.xconf" file. The XMLUI does not seem to obey the "colourisation". I have tried the following to remedy this: 1. Sort faculty handles ascending and descending in the "xmlui.xconf". 2. For all themes, disable the browser caching in the "sitemap.xmap" files. I have installed the "cache killer" app in my Google Chrome browser to test if this is a cache problem. I have also reset the "java cache" in the XMLUI admin control panel to do testing. The page metadata correctly displays the theme name and path. See: http://scholar.sun.ac.za/?XML and http://scholar.sun.ac.za/handle/10019.1/1?XML I simply cannot find a cause, why the theme colour is not obeyed strictly per faculty. Any help appreciated. Depending on the responses to this question on the list, I may submit a bug report. This is supposed to be one the big selling points of the XMLUI, the ability to theme communities and collections etc..., but for me it does not work ;-( I suspect something in the following code is not robust.
