Pete Finnigan's Oracle security weblog

Pete Finnigan's Blog just mentioned the fact that the Latest Oracle CPU(Critical Patch Update)  is out.

one quote i found really interesting in the article was  the fact that they had broken up the patches into molecules.


"The napply CPU is an enhanced CPU format for Oracle Database Server for Unix and Linux platforms version and onward (including and 11g). In a napply CPU, the security fixes are now grouped in what are called molecules. Each molecule in the CPU is independent, and does not conflict with other molecules in the CPU. Conflicts between molecules occur when fixes included respectively in each molecule affect the same file or group of files."

Which also goes on to say that OPatch will have  a new parameter ?-skip_duplicate to only apply new patches thus limiting the amount of change to the system. 

I dod agree with Pete this will relieve a lot of anxiety and make people apply the patches with more confidence. As to How it works the first time we have yet to see.

Thanks Pete for  the excellent summary of the CPU as usual.

Scott/tiger for system administration?

I'm listening in on the Oracle 11g Webcast and heard Charles Phillips referring to scott/tiger as an initial system administration logon.
I've always thought of that account as the demo schema for schema .
personally i never used it for any administration.
Am i wrong or did i hear wrong .

Oracle blog: Change behavior of GROUP BY clause in 10g.

 Jaffar at this blog has a detailed explanation of   a change in behaviour in the way data result sets are retrieved in 10g. This is interesting to learn since i'm working on a couple of upgrades and i know Oracle has never guaranteed results in an ordered but people have gotten it in an ordered fashion. I'm going to throw this out to my developers and see if this affects any of their code.

Thanks jaffar for pointing this out.

Pythian Group Blog » Oracle Releases Method to Disable AWR Collection

from What i understand Oracle has now officially released a method

to disable AWR for people without the Diagnostic Pack license. It seems this was done after Mark Brinsmead's wonderful attempt in asking  ORACLE for providing this framework as part of the database.

One thing that Paul Valee pointed  out is that ORACLE still wants people to keep AWR enabled . Quote from ORACLE

"Oracle, therefore, recommends that all customers, with or without Diagnostic Pack license, leave AWR enabled so that they can benefit from features that do not require pack license but implicitly use AWR"


This means that  maybe there still might be hope .
