All our distance learning students authenticate through CAS into their blackboard account. We also have several casified applications. It may just be too much load. Performance is great though.
I noticed the documentation for JDBCTicketRegistry and BerkleyDB is empty. I would really like to play with these alternatives to ticket registry. --- On Wed, 9/3/08, Scott Battaglia <[EMAIL PROTECTED]> wrote: From: Scott Battaglia <[EMAIL PROTECTED]> Subject: Re: CAS memory issues To: [EMAIL PROTECTED], "Yale CAS mailing list" <[email protected]> Date: Wednesday, September 3, 2008, 10:05 AM We maintain a list of documentation here: http://www.ja-sig.org/wiki/display/CASUM/Home You'll find the different ticket stores there. But again, it would seem weird that you're having memory issues, as the same mechanism has been used for years (though your usage pattern could be significantly different I guess). -Scott On 9/2/08, Renato Giron <[EMAIL PROTECTED]> wrote: Thank you Scott, I will try to get the memory dump on the production server (since I don't think it will be worth doing it on test.) In the mean time, Is there a documentation that I can read for setting up DB ticket store? Thanks for your time and support. --- On Tue, 9/2/08, Scott Battaglia <[EMAIL PROTECTED]> wrote: From: Scott Battaglia <[EMAIL PROTECTED]> Subject: Re: CAS memory issues To: [EMAIL PROTECTED], "Yale CAS mailing list" <[email protected]> Date: Tuesday, September 2, 2008, 5:15 PM We've been using CAS in production since 2005 with the same in-memory ticket store (and most likely less allocated memory and haven't experienced that problem). If you can, use a tool to get a memory dump and see what objects are being held on to. Also if you wrote any custom code make sure its not holding on to anything accidentally. -Scott On 9/2/08, Renato Giron <[EMAIL PROTECTED]> wrote: Hello friends, I posted this message several months ago. I still have the same memory issue even after upgrading to 3.2.1. Can some one point me to the right direction for utilizing a database for tickets registry storage? Thanks in advance. "My CAS 3.1 application does not free up memory considerably during garbage collection. The amount of memory that is freed up decreases on each garbage collection until there is no more memory available and the application crashes. I looked at the CAS logs and it seems to be clearing expired tickets every three hours. I am using the WAR file that comes with the distribution with no changes (except for UI) My application is used by approximately 30K users and it seems to be handling the load with no problems. I am new to CAS so I would like to hear some advice from the experts. Is this a CAS design issue? Is there a way to optimize tickets registry? Can tickets be registered on database engines (like MySQL)? This is my current configuration: -Windows 2003 Server -Tomcat 5.5 JRE 1.6 -CAS 3.1 -Xms512m -Xmx1600m" _______________________________________________ Yale CAS mailing list [email protected] http://tp.its.yale.edu/mailman/listinfo/cas -- -Scott Battaglia PGP Public Key Id: 0x383733AA LinkedIn: http://www.linkedin.com/in/scottbattaglia _______________________________________________ Yale CAS mailing list [email protected] http://tp.its.yale.edu/mailman/listinfo/cas -- -Scott Battaglia PGP Public Key Id: 0x383733AA LinkedIn: http://www.linkedin.com/in/scottbattaglia
