Oracle keeps many users waiting on April patches
"MAY 02, 2006 (IDG NEWS SERVICE) - Testing problems are forcing some Oracle Corp. users to wait a little longer than usual for the company's latest round of security patches, the first of which were released last month."
This is an interesting article but I did point some of this issue out in my blog on April 18th in a post titled "What is amazing is that a lot of CPU patches are not available until May!!".
