Re: [Dspace-tech] ldap dspace
Hi Susan, I started receiving the following messages in my dspace log today: 2007-04-17 15:29:25,244 WARN org.dspace.app.webui.servlet.LDAPServlet @ anonymous:session_id=7EFF45148568493C0EB81D2E82FDCF62:ip_addr=128.172.144.44:l dap_authentication:type=failed_auth javax.naming.AuthenticationException: [LDAP: error code 49 - NDS error: failed authentication (-669)] I'm guessing you are authenticating against Novell? The standard LDAP error code 49, and Novell's error code -669 just mean bad username or password, so aren't very helpful. One little tool that is very useful in debugging LDAP problems is the 'LDAP Browser'. http://www-unix.mcs.anl.gov/~gawor/ldap/ You can give this the same information that you used to configure LDAP in DSpace, and see if it lets you in. If it does, the problem will be with DSpace (although you say you have changed anything so hopefully it is fine), or if it doesn't, the problem will be with the LDAP service. If it does also fail, it gives you a nice tool to take to the LDAP administrators to show that connections are not working. They should be able to turn on tracing to watch authentication attempts to their LDAP service to see what is happening. Good luck!

If your hardware is large enough to cope with number of connections, you could think about increasing the number of connections in the pool. (change the number, restart Tomcat). 2) For some reason, DSpace might not be letting go of some old connections, or they might be stuck in some way. If you are using UNIX and postgres, you should be able to see the connections, and what they are doing, by running a 'ps' on them (make sure you're screen is wide to see what comes at the end of the line).

Re: [Dspace-tech] Large files and DSpace
Most large files are audio/video files. Downloading the whole file may not be a good solution here. Maybe adapting the large files to suit the users' needs, e.g., if the user's bandwidth or usage environment is limited, then adapting the audio/video files into lower quality streams, would be a more sustainable approach? Besides, DSpace does not necessarily just give whatever it holds to the users. The dissemination can be adaptive based on various factors. Building such an adaptive dissemination framework shall be very interesting.

Re: [Dspace-tech] Cannot get a connection, pool exhausted
In our experience, this problem appears to be due to a bug somewhere in freeing connections back to the pool--we tend to see steady linear growth in the number of 'idle in transaction' connections until we get this error. These are visible with ps. Increasing the number of connections in the pool, for us, only delayed the occurrence of the problem. Ultimately the number of 'idle in transaction' connections would climb to the max. We put a workaround in place. This is a root crontab entry: # kill old 'idle in transaction' postgres processes, leaving up to 10 * * * * * while /usr/bin/test `/usr/bin/pgrep -f 'idle in transaction' | /usr/bin/wc -l` -gt 10; do /usr/bin/pkill -o -f 'idle in transaction'; done At one point I was entertaining a theory that the Apache connection pool manager delivered with DSpace was a stale version. To date, the workaround has worked so well that I'm not sure that theory has been fully explored. Also, FWIW, there have been lengthy discussions on this list about this topic already. You would probably find the previous thread useful as I'm quite sure I'm not retelling everything here.

Re: [Dspace-tech] DSpace a memory hog?
This depends on your definition of a memory hog. We run a relatively large instance of DSpace and we allocate 512MB to Tomcat, about 100MB to Postgres, and 256MB for daily indexing runs (via the dsrun script). In earlier versions of DSpace the indexing routine needed to be patched to work around a poor implementation that caused memory allocation to be linear with repository size. Without that, we were running out of memory during indexing. I believe that patch is now part of the base. We run comfortably inside 2G of physical memory. I may have considered that a memory hog 5 years ago, but today I consider it light.

Hmmm... in theory, whilst transactions can 'fail', they should always rollback or commit. If we assume something really obscure isn't happening for now, it leaves us with two possibilities: 1) The Context has dropped out of scope without being cleaned up 2) A thread is still executing, and is still using it's Context / transaction. A few obvious things here spring to mind: 1) Check the logs for Exceptions - one being thrown without a finally to clean up the Context would be a likely (if not only) suspect for a Context being lost. 2) Launch Tomcat under JDK 1.5 with the JMX interface enabled, and attach JConsole to it (JMX adds little overhead to the server, and you don't need to attach JConsole until the problem arises). From JConsole, you can see how many Threads Tomcat is currently using, what status they are in and often a stack trace - so you can see where in the code that Thread is being blocked. (As an aside, we had a problem with a different application, where sooner or later - and often sooner - Tomcat would suddenly grind to a halt and stop serving requests. Using JConsole showed that the Threads were all blocked (and increasing in number with every request), and the point at which most of them was blocked was in trying to obtain a database connection from a custom built pool - and it actually came back to a background thread that was trying to close unwanted connections at the same time the business logic was trying to close the same connection. Both Threads got hung up on each other, and everything else blocked as the pool couldn't give new connections whilst the clean up was in progress.) Also note that JConsole has a button to force garbage collection - this may help in determining if there are dangling Contexts. If they (and therefore the transactions) disappear after forcing the garbage collection, then something was dangling - although that wouldn't tell you why).

Re: [Dspace-tech] ldap dspace
Thanks Stuart, I ended up writing a php script to connect to the ldap server from our dspace server. Worked. Long story short. There were about 3 changes going on at the same time. The only one I had control over was a stupid error on my part - through the course of the past few weeks, the config file was clobbered (only on 1 line) and one letter was changed in the ldap object context. I guess no one noticed as there are only 3 people testing; I was able to log in, but no one else was. Alas. Thanks for the tool tip - We use softerra on windows, but I don't have anything loaded on linux. Thanks again, Susan Stuart Lewis [sdl] wrote: Hi Susan, I started receiving the following messages in my dspace log today: 2007-04-17 15:29:25,244 WARN org.dspace.app.webui.servlet.LDAPServlet @ anonymous:session_id=7EFF45148568493C0EB81D2E82FDCF62:ip_addr=128.172.144.44:l dap_authentication:type=failed_auth javax.naming.AuthenticationException: [LDAP: error code 49 - NDS error: failed authentication (-669)] I'm guessing you are authenticating against Novell? The standard LDAP error code 49, and Novell's error code -669 just mean bad username or password, so aren't very helpful. One little tool that is very useful in debugging LDAP problems is the 'LDAP Browser'. http://www-unix.mcs.anl.gov/~gawor/ldap/ You can give this the same information that you used to configure LDAP in DSpace, and see if it lets you in. If it does, the problem will be with DSpace (although you say you have changed anything so hopefully it is fine), or if it doesn't, the problem will be with the LDAP service. If it does also fail, it gives you a nice tool to take to the LDAP administrators to show that connections are not working. They should be able to turn on tracing to watch authentication attempts to their LDAP service to see what is happening. Good luck!

[Dspace-tech] dspace.log file owned by root
I'm finding that my dspace.log file is sometimes, not always, owned by root. I think what is happening is that when it is time to roll the file, some how root becomes the owner sometimes. Any ideas what could be causing this, or where I should look? I've checked the log4j.properties file and it looks fine, not any different from what it has been since we installed DSpace a few years ago. I'm also seeing the handle-plugin.log is always owned by root. Thanks!

Re: [Dspace-tech] Assetstore physical storage (Amazon's Simple Storage Service: S3)
Richard: I'm putting up a prototype implementation of (inter alia) an S3 backend on the DSpace wiki. (see 'PluggableStorage' page). Would love volunteers to vet it (not ready for production).

That said, the intention was that storage would be made pluggable -- so you could have RDBMS, SRB/iRODs, open-source GoogleFileSystem, LOCKSS-ish etc. storage. That pluggability ended up being one of the many non-critical-for-version-1 features we had to drop to get DSpace 1.0 finished :-) There are some projects (e.g. the MIT ones) looking at how to really accomplish this. Over the past few weeks I've been using Amazon's Simple Storage Service (S3): http://www.amazon.com/gp/browse.html?node=16427261 At this point I've merely been using it to backup web servers and development directories. This has involved the simple upload of compressed tarballs (using the Java app. jSh3ll) but also the synchronising of file systems (using the Ruby app. s3sync). In all, I've been pleasantly surprised by the results. It would seem that the S3 storage system promises to be more resilient than anything I could build at a reasonable cost. Although I've only been using S3 for remote backup, it seems that it can also be used as a live file system for storing and retrieving data for web apps. I am wondering then, if anyone, may be able to suggest how it might be possible to configure (cajole) DSpace-1.4 into using S3 as an assetstore. The Amazon blurb says that S3: `Uses standards-based REST and SOAP interfaces designed to work with any Internet-development toolkit.'

Re: [Dspace-tech] DSpace a memory hog?
Pan, Dspace is a memory hog considering the functionality the application provides. This is mainly due to the technological choices made by the founders of the Dspace project, and not the functional requirements the Dspace project fulfills. Application and memory bloat are pervasive in the IT industry. Each individual organization should look at their requirements whether they are hardware, software or both. Having to dedicate a machine to an application, especially a relatively simple application like Dspace, is wasteful for hardware resources and people resources.

Re: [Dspace-tech] DSpace a memory hog?
Well, as I said at first, it all depends on your definition of what a memory hog is. Today's hog fits in tomorrow's pocket. We better all already be used to that. Also, I don't think for a *minute* that the original developers of DSpace made a casual choice about their development environment--in fact, I think they made a responsible choice given the alternatives. Let's give our colleagues credit that's due. Their choice permits scaling and fits well for an open-source project. Putting the general problem of memory bloat in their laps seems pretty angsty to me. Lastly, dedicating a server to DSpace is a choice, not a necessity. We as implementors have complete freedom to separate out the database and storage tiers, and mechanisms exist for scaling Tomcat horizontally as well. In the other direction, I suspect people are running DSpace on VMware or xen virtual machines, too.

Re: [Dspace-tech] DSpace a memory hog?
Thank you all for giving your opinion! Technically, is it the web application or the indexer that requires most of the memory? What data is kept in memory all the time (even when nobody is searching)? Is the memory usage proportional to the number of concurrent sessions?

Please review the handle information in the documentation http://www.dspace.org/technology/system-docs/install.html you'll find that the default handles are just 123456789/ because you do not have a configured and registered a handle system. The handle server, which runs as a separate process on your machine provides a means to expose persistent urls for your items that resolve via the handle.net's global handle resolving service.
