Oracle Enterprise Linux 5 Update 4 available on ULN
Oracle Enterprise Linux 5 Update 4 has been added to Unbreakable Linux Network (ULN) Customers with Linux support from Oracle may download and install OEL 5.4 packages for i386 and x84_64 architectures. Itanium packages are coming soon. Also coming soon: OEL 5.4 on public-yum.oracle.com and installation media on edelivery.oracle.com/linux
As for the rumors that OEL is based on CentOS? Only in a universe where time flows backward. Hint: Centos 5.3 was announced on April 3rd, 2009 and OEL 5.3 was announced on January 28th, 2009, more than two months earlier. We have no relationship with CentOS and do not rely on them.
Update:Installation media now available via edelivery.oracle.com/linux
