This should be available as an argument for update-discovery-index -o, and would need to be added to IndexClient, and SolrServiceImpl.

It also spits out the amount of time taken to run the optimize task. Once you patch your instance. You can execute this with /dspace/bin/dspace stats-util --optimize or /dspace/bin/dspace stats-util -o Output looks like: SOLR Optimize -- Process Started:1277486321673 SOLR Optimize -- Process Finished:1277486321738 SOLR Optimize -- Total time taken:65 (ms).

[Dspace-devel] [DuraSpace JIRA] Updated: (DS-712) DSpace Fails to Check if a Handle is already assigned before assigning a new handle
[ https://jira.duraspace.org/browse/DS-712?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Tim Donohue updated DS-712: --- Priority: Critical (was: Blocker) Attachment: update-sequences-postgres.patch I've decided to take a slightly different route to resolving this issue for AIP restores. I've attached a patch that makes a change to the 'update-sequences.sql' script for PostgreSQL (still working on an Oracle version -- will be attached as soon as I complete it). This patch changes how the 'handle_seq' is updated, such that it is now based on the *maximum handle suffix* rather than the maximum value of 'handle_id' in the 'handle' table. So, as an example, if your maximum handle was 123456789/6647, but the maximum 'handle_id' is just 102, then running 'update-sequences.sql' would update your 'handle_seq' to 6647 (which means the next handle created will be 123456789/6648).Previously, it would have updated the value to 102 (which, as described above, could result in conflicts in your DB). In the end, if the 'update-sequences.sql' script is properly updating the 'handle_seq' to avoid conflicts, then we can just recommend to *always* run 'update-sequences.sql' after a major AIP restore or replace. This will ensure the DB never enters an unstable state. Comments or counter-proposals welcome! DSpace Fails to Check if a Handle is already assigned before assigning a new handle --- Key: DS-712 URL: https://jira.duraspace.org/browse/DS-712 Project: DSpace Issue Type: Bug Components: DSpace API Affects Versions: 1.7.0 Reporter: Tim Donohue Assignee: Tim Donohue Priority: Critical Fix For: 1.7.0 Attachments: update-sequences-postgres.patch Not sure how this hasn't come up before, but I just noticed this in terms of testing the new AIP Backup/Restore functionality (DS-466). DSpace currently makes a highly flawed assumption when assigning new Handles. It will *always* assign a Handle equal to the next available value in the 'handle_seq' (which is just the max value of 'handle_id' in the 'handle' table). See the HandleManager.createHandle() method. This becomes extremely fragile when you have content which has been migrated or restored from another DSpace (for example, via the AIP backup/restore feature). In those instances, it you may end up restoring/migrating content that looks like this: handle_id = 44 (or whatever the next value in 'handle_seq' is) handle = 123456789/50 (or whatever the restored handle should be) Once the value of 'handle_id' reaches the suffix value of a restored handle, then you will run into database conflicts will be unable to submit any new content into DSpace. So, in the above example, as soon as 'handle_seq gets to the value of 50, Dspace will attempt to assign a new handle of '123456789/50' to the next object created. However, as that handle is already in use, the new object will always fail to be created. In other words, the DSpace system will fail to accept any new objects. The fix would be to first ensure a handle is *not* already in use before assigning it -- essentially looking for the next available handle (rather than the next value of 'handle_seq) before assigning the handle. However, I need to determine a reasonable way to locate the next available handle (preferably something that will scale relatively well for larger installs). Ideas / thoughts / brainstorms welcome. I've marked this as a Blocker for DSpace 1.7.0, as it essentially makes your DSpace unusable if you were to encounter this bug. (The only way to get around this issue if you encountered it is to manually increase your handle_seq so that it's greater than the largest handle suffix in your system.) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.duraspace.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira -- Nokia and ATT present the 2010 Calling All Innovators-North America contest Create new apps games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev ___ Dspace-devel mailing list Dspace-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dspace-devel
[Dspace-devel] Fwd: [Announce] Reminder: Apply to be a mentoring organization for Google Code-in by 29 October at 23:00 UTC
This almost slipped past my radar. Is this something the DSpace community might have a interest in participating within. Unlike GSoC it is not stipend driven, but award driven and it is oriented at High school students, not college students. The objective is to get Highschool students exposed to Open Source by getting them to contribute to Open Source projects at various levels (coding, documentation, graphic design, etc). thoughts?

Thanks, Carol - Hi everyone, Starting today we are accepting applications from organizations who have participated in a previous Google Summer of Code (you!) to get involved with our contest for 13-18 year olds, Google Code-in [0]. If you haven’t read up about Google Code-in, you can check out our announcement [1] to this list from a couple weeks ago or read our blog post [2] about the contest. If your org has decided it would like to apply to participate in the contest, you can fill out the application [3] on Melange now. The deadline for applications is 29 October at 23:00 UTC. Also, if you want to look over the rules for the contest before applying to participate they can be found on the organization application [3] at the bottom. They will also be posted on the Google Code-in website [0] in the next couple days in other languages. We hope your org will consider participating.

[Dspace-devel] Welcome to the latest DSpace committer: Sands Fish
Dear DSpace community member, The DSpace committers team are delighted to announce a new member to the group: Sands Fish from MIT. Sands has been an active member of the DSpace community for some time, contributing patches, helping fix bugs, and to develop new features in the software. Sands started programming in the early 80's when he discovered the Beginner's BASIC book that came with his TI-99/4a. He earned a degree in Computer Science from Assumption College and has worked on a wide range of software and projects, from embedded code in network analysis boxes, to RPG code for AS220 systems, to managing development groups in the start-up environment. Most recently, he has focused on web applications and services, specifically in the context of DSpace and the semantic web. He currently works as a software engineer for the MIT Libraries. We are always on the lookout for new developers, contributors, and committers within the DSpace community. Anyone who would like to get more involved is encouraged to do so. You're also welcome to contact us at any time if you'd like ideas of how to start contributing: - https://wiki.duraspace.org/display/DSPACE/DSpaceContributors Contributions can take many forms, from writing code to editing documentation, or testing new releases or designing new themes for our user interfaces.
