started the morning with Julian Dyke’s session on library cache. It was quite informative. I just attended both of Tanel Poder’s sessions and he had some very radical Oracle research techniques definite don’t do this at home material.
I can’t say a lot about presentations I went to as my head was completely empty after my 3 sessions. Last session was on Oracle Streams CDC – I am still not sure what the added value of CDC compare to regular Streams functionality. But the truth is I couldn’t think about anything else but Guinness at that point…
Martin Wisniewski, Harish Ramchandani and I are headed to GITEX 2006 in Dubai tomorrow. If you haven’t heard of this trade show, let me tell you it’s huge. It’s measured at one of the world’s top three IT trade shows by attendance, which last year was about 80,000 people!
Two new features that really caught my eye were :the ability to apply application upgrades while the database is up and the connection pooling IN the database.
The client entrusted me with the migration of one of their mission critical apps running 8i on HPUX to — drum role please — 9i … on … IBM Mainframe running os390 (z/os). For this client, we were able to shave $600,000 (not just the Oracle license, but also the external costs of maintaining the environment) by migrating just one HPUX machine over to the mainframe with maybe 30 or more to go.
UKOUG 2006- I have three sessions there. These are first three right on Tuesday after the Opening Technical Keynote by Tom Kyte.
Over the last weekend I had the pleasure to do an 8i -> 10g, Solaris -> Linux migration. Talk about going in head–first. Now, whenever I run into a situation like this, we generally recommend a two–step process so that we can iron out bugs and be able to isolate causes. However, we were under serious time constraints, and we decided to just go with the following simple plan and move straight there.
Welcome to the 18th Log Buffer, the weekly human-edited review of news from database blogs.
While reviewing some material in advance of my presentation at UKOUG Conference 2006, I found an interesting change in RMAN behavior in Oracle 10g. The difference is in the way RMAN handles the case when an incremental level 1 backup is taken without an available level 0 backup. This probably won’t affect anyone much, but I found it interesting. And actually, there are scenarios in which it might cause issues.
I have been working on issues that relate to security certification at a number of our clients, and I can’t say that I have anything good to say about it.. Compliance standards are set such that you are protecting against the bulk of the people out there. This is generally very good practice, but when you rely on standardization alone, you open yourself to real danger.
