RE: Application Server Caching

[Goulet, Dick]

Ryan,       He has a point.  If you look at 9IAS's architecture there is a cache database at the apps server.  The trick is to know when the data your looking for in cache is no longer valid.  A certain children's apparel/toys site did that to me back in October.  I'm still torqued at them.   Dick Goulet Senior Oracle DBA Oracle Certified 8i DBA -----Original Message----- From: Ryan [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 14, 2004 5:14 PM To: Multiple recipients of list ORACLE-L Subject: Application Server Caching I heard a presentation from a front end performance analyst last night from www.tangasol.com (im not associated with them at all). He was pretty impressive.   He argued that accessing the database is expensive. He also argued in favor of caching data at the application server level. Have any of you worked with this? What are your opinions? His opinion was that people go back to the database to ask the same question way too often and cause a botteneck, if you can cache these frequently asked questions at the front end, it will significantly scale better.
