Just a quick note: Log Buffer #19 is running a little late, but our readers can expect it to be published today.
Yesterday I attended Julian Dyke’s session on Inside Rac and had the good fortune to be node 2 in a 4way node cluster. And Julian clearly demonstrated the importance of a good network in RAC, particularly for the internode interconnect.
Interesting was the Anti-Tuning RAC round-table with conclusion that more or less majority is running RAC because they have way too much money/time/hardware/name it.
It’s lunchtime and have attended three excellent sessions today. Jonathan Lewis’s Moving from RBO to CBO, James Morles Storage Internals for the Oracle Architect, and Joze Senegacnik’s Tuning with SQL Profiles. And although it was difficult to get up so early this morning, it was definitely worth it!
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.
