I meant to blog about this awhile back but I got sidetracked.
Last month, Oracle announced that for Oracle 12c, it would no longer be offering two types of patches every quarter in the Cumulative Patch Update (CPU). Currently for 11g, you can get a Security Patch Update (SPU) which contains just security fixes or the Patch Set Update (PSU) which contains the SPU plus some bug fixes. Starting with Oracle 12c, only the PSU will be available.
Yesterday, I blogged about a good white paper I found from Maria Colgan of Oracle Corp relating to the CBO. I also discovered another good paper. This one discusses all of the CBO-related enhancments for Oracle 12c. You can find this paper here.
