Introducing UEK4 and DTrace on Oracle Linux for SPARC

About 2 months ago we released the first version of Oracle Linux 6, Update 7 for SPARC. That was the same version of Oracle Linux used in Exadata SL6.

It contained support for the various M7 processor features (DAX, ADI, crypto,...), gcc optimizations to support better code generation for SPARC, important optimizations in functions like memcpy() etc. We also introduced support for...

One thing we discovered during testing of OL6.9 was that a recent change in "upstream" glibc can cause memory corruption resulting in a database start-up failure every now and then. Since we caught this prior...

Oracle Linux and Software Collections make it a great 'current' developer platform

Oracle Linux major releases happen every few years. Oracle Linux 7 is the current version and this was released back in 2014, Oracle Linux 6 is from 2011, etc... When a major release goes out the door, it sort of freezes the various packages at a point in time as well.
