The patch is available on MOS for Linux and Solaris and can be used for those customers who want to download the recommended releases for all components for the Oracle Exadata Database Machine in one go.
In this QFSDP you will find the Quarterly Database Patch for Exadata a.k.a QDPE. The current version is Jan 2012.
This is part of a new strategy for patching Exadata that reduces the number and frequency of patches released to customers even more.
For the database: while also continuing to make important fixes available in monthly or bimonthly interim bundle patches, Oracle recommends most customers only applying the QDPE. The currenly recommened QDPE is available via MOS patch 13513783.
MOS note 888828.1 is still the recommend place to look first for the latest information regarding recommend/supported releases.
