If this is not the case, hopefully somebody running DSpace under Windows can respond. Have you created the database user 'dspace' and have you configured your database server to allow connections for the database user 'dspace'? The installation documentation section Relational Database: (PostgreSQL or Oracle) describes some changes you need to make to your postgresql.conf and pg_hba.conf to allow connections. - Desmond -- Desmond Elliott | Hewlett-Packard Limited registered Office: Research Associate| Cain Road, HP Labs | Bracknell, Bristol, UK | Berks +44 117 312 8526 | RG12 1HN.

Re: [Dspace-tech] item rating system
George, The recommender system project at HP Labs is a research project and has no targeted release date, yet; we are planning to release the code as an add-on in the future. A technical report will be published which explains what we have done and how we have done it. I'll send an email to the list when the report is available. - Desmond -- Desmond Elliott | Hewlett-Packard Limited registered Office: Research Associate| Cain Road, HP Labs | Bracknell, Bristol, UK | Berks +44 117 312 8526 | RG12 1HN.

Is there any release date for the recommender system? George Scott Phillips wrote: John, Absolutely, I when I said well suited for manakin I meant in the presentation of the rating system using the modularity provided by the framework. So it can be build as an addon aspect without necessarily being integrated into the core of dspace. I've only heard a few whispers about the recommender system that is being developed by HP, but that is a good point that there is some crossover. Perhaps the rating system should feed into the recommender system as a data source. Do you know some contacts George can use to find out more about the these projects and HP and Minho? However, I can see the purpose and use-case of a rating system distinct from recommender system. Scott-- On Apr 9, 2008, at 1:31 PM, John S.

Yes, the manner and style in which ratings are solicited and recommendations presented to the user might be well-suited to manakin, but the actual thing that is persisting individual ratings, compiling them and presenting recommendations must surely be deeper...

Re: [Dspace-tech] Long Delay in doing Submit - Part 2
I hypothesise that retrieving the ResourcePolicy for each of the 359 Collections and then determining if a user is a member of the Group associated with the Collection is why there is a long delay in submissions from the MyDSpace interface. George could insert log.info() method calls into the SubmitServlet.java file at line 306, and after line 309, and re-compile and re-deploy. These calls would log the time of the start and the end of the operation for users who are / are not administrators to attempt to help determine if this is the reason for long delays. If this proves there is an objective difference in the time then the log methods can be moved closer to the end of the call tree to determine exactly where most computation occurs. The SubmitServlet adds a Collection[] to the select-collection step of the submission process [-1] line 308. This Collection[] is created through a call to the Collection.findAuthorized(context) static method [0] line 1150. The findAuthorized() method calls the findAll() method, [0] line 273, which returns a list of all Collections in the collection database table which should not be an expensive operation since it queries the database and retrieves 359 rows. A line contained inside the findAll() method block, line 285, determines if the Collection object to be added to the Collection[] is cached in memory. This should not be an expensive operation since the fromCache() method determines if the Collection object is cached in a HashMap - which offers O(1) access, [1] line 289. The returned Collection[] is then examined, for each Collection object, to determine if the current user has authorisation to write to that Collection. The AuthorizeManager class method authorizeBooleanAction() [2] line 217, calls authorizeAction() [2] line 131, calls authorize() [2] line 258. The authorize() method in AuthorizeManager retrieves a ResourcePolicy and determines if the user is authorized as per the ResourcePolicy to have access to the collection. Users who are admins do have have to step through the ResourcePolicy stage. George states that he suffers a delay when trying to submit from the MyDSpace page but that it is a shorter delay than what others are experiencing - 30s - 60s vs 60s - 300s. The only stage in the process I can determine where there is a difference between Admins and Users is at this point. Having to retrieve the ResourcePolicy for each of the 359 collection objects and determine if a user is part of that ResourcePolicy could be the choke point. I appreciate any thoughts on my analysis of what could be causing the problem that George is experiencing.

Back in January, I wrote to the list about a problem we are having (at Cornell) with DSpace after we migrated from v. 1.3.2 to v. 1.4.2. Basically, if someone logs into DSpace by clicking on My DSpace and then clicks on the Start a New Submission button, there can be a delay from anywhere from 30 seconds to several minutes before the Submit: Choose Collection screen appears. Clicking on the Start a New Submission button in My DSpace can run the CPU usage up over 40%. This doesn't happen if one goes directly to the Collection to which he or she is authorized to submit and clicks on the Submit to this Collection button there. Randall Floyd of Indiana University thought that this might be a cleanup program in PostGreSQL, but I run vaccumdb nightly and do a re-index daily. Claudia Jurgen of TU Dortmund suggested that this may be the result of a complicated Community/SubCommunity/Collection structure (we have 118 Communities/Sub-Communities and 359 Collections). I have been looking at alternatives. I have put a message on the My DSpace main page telling people
