Hi... 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 to go to the collection they want to submit to and click on the "Submit to this Collection" button there, but (as you can imagine) most people aren't doing that, and I am beginning to receive complaints from our users. Is anyone else having this problem? Does anyone have any ideas as to what I can do to make this a little bit better? Thank you! (PS. I am running a SunFire-480-R with 4GB of memory and 8GB of swap space. I am running PostGreSQL 7.2.3 and Tomcat 4.0.6.) *************************** George Kozak Digital Library Specialist Library Systems 501 Olin Library Cornell University 607-255-8924 *************************** [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
