Windows bundle patch – regression tested from 10.2.0.4 onwards
I just finished reading “preamble” from MOS note “161549.1 1Oracle Database Server and Networking Patches for Microsoft Platform”, specifically:
Patch sets increment the 4th digit of the version number e.g. 10.2.0.1.0 to 10.2.0.4.0, these patch sets are fully regression tested in the same way that the base release is (i.e. 10.2.0.1.0). Customers are encouraged to apply these fixes.
From 10.2.0.4 onwards each Windows bundled patch goes through full regression testing because it includes a large number of dependent fixes, CPU, DST and PSU. Oracle recommends all customers apply the latest bundle as soon as it is convenient irrespective of encountering a specific problem resolved by the bundle.
…which I found reassuring and amusing at the same time.
