Re: [Dspace-tech] Tomcat cluster configuration
Thanks, Jesus. Since you and James are discussing it, I'll make some
comments about what's unclear to me from reading this page, as a novice:
-What is the path of server.xml?
-How do we modify the objects that sessions of DSpace uses?
The structure of this page
http://wiki.dspace.org/index.php//HOWTO_Clustering
is also unclear to me--it seems like a list of options that were tried. It
would be preferable to me (as a novice), to have a recommendation at the
top, clearly marked as such, followed by categorized alternatives. (For
instance, how does Terracotta relate to Tomcat)?
Scalability is definitely important, so and I hope that those who understand
it will continue improving these instructions, and provide some scalability
metrics as well at the stub
http://wiki.dspace.org/index.php/ScalabilityMetrics
Thanks again for your improvements!

Hi,
It would be great if you could add some notes to the (embarrassingly
incomplete) wiki page that I started a few months ago:
http://wiki.dspace.org/HOWTO_Clustering
The page is mostly focussed on clustering of the database layer, so it
would be good to get more detailed information about setting up Tomcat.
cheers,
Jim

Hi, I have been configuring Tomcat and DSpace to accomplish tomcat
clustering and the persistence of sessions in two machines that are
running Tomcat at the same time. First, I added the line of server.xml
under the Engine line:
Engine defaultHost=localhost name=Catalina
Cluster
className=org.apache.catalina.cluster.tcp.SimpleTcpCluster/
...
Moreover, we need to modify the objects that sessions of DSpace uses,
consequently changing this objects for implementing the
java.io.Serializable. In fact, DSpace's sessions only use one object,
RequestInfo.java:
public class RequestInfo implements java.io.Serializable{.}
I made this changes with DSpace 1.4 , Tomcat 5.5.17 and Tomcat 6 and
are
working very well. I hope this explanations can help anyone.

Re: [Dspace-tech] Fwd: Problem with Data Provider Validation
If there is no date range specified, all records with the specified metadataPrefix must be returned by protocol section 2.7.1: http://www.openarchives.org/OAI/openarchivesprotocol.html#SelectiveHarvestingandDatestamps Harvesting is restricted to the range specified by the from and untilarguments, extending back to the earliest datestamp if from is omitted, and forward to the most recent datestamp if until is omitted. -Jodi On 6/6/07, Graham Triggs [EMAIL PROTECTED] wrote: Not really. The badArgument is valid when you don't specify a metadataPrefix, and the noRecordsMatch error is valid when there are no records that match the date range specified. If you simply include a from timestamp, eg: http://dspace.udel.edu:8080/dspace-oai/request?verb=ListIdentifiersmetadataPrefix=oai_dcfrom=2001-01-01T00:00:00Z then it works. I don't think there is anything wrong with the harvesting code per se, it just looks like it is incorrectly interpreting a from date when you don't specify one. Although according to the oaicat.properties below, the earliestDatestamp is set to 2001-01-01T00:00:00Z - exactly what I'm passing in the above url, and which works!
