Where can I find information about Oracle patch sets and bug fixes?
A bug fix (also known as an interim patch as of Oracle 9i) is a correction provided by Oracle (depending on the patch set used) to eliminate a particular problem. A patch set is a collection of corrections provided as a unit. The current patch set version is logged in the fourth digit of the Oracle release specification (for example, Oracle 9.2.0.3.0 -> patch set 3 installed for Oracle 9.2.0). Bug fixes always depend on the current patch set version. If there is a bug fix for a patch set version, the fix is usually already contained in the next-highest patch set. Notes 539921 (9.2) and 871735 (10. 2) contain information about the Oracle patch sets currently released by SAP. Notes 938986 (9.2), and 871096 (10.2) contain information about important bug fixes.
