WebCast: Exadata Storage Layout

Yesterday I gave a web cast for the Oracle Exadata (IOUG SIG) Linked-In group. The presentation was entitled “Exadata Storage Layout” and touched on the components of Exadata, ASM basics, and storage provisioning. The main thrust of the web cast was to discuss configuration options for cell disks and storage cells. Cell disks are carved up into grid disks which are presented to ASM on the database servers where they are used to create disk groups for database storage. Storage cells may also be provisioned to the database servers in such a way as to create multiple storage grids. Finally, we discussed a few options for storage cell and database server provisioning within RAC and Non-RAC configurations.

I hope you found the presentation helpful. My email address is located on the last slide. Feel free to email me with any questions we didn’t have time to cover in the web cast.

Exadata Bundle Patch 5 Gotcha's

A couple of months ago we became proud parents of a bouncing baby Exadata V2, (1/4 rack). I had about two weeks to configure it and get up to speed on the high points before we were to begin work on our first proof of concept (POC) for a local client. I had just enough time to patch the storage cells up to version 11.2.1.2.6 configure storage and create the databases. Well we’ve been working it pretty hard for the last couple of months with customer POC’s and our own testing but today I finally got a chance to get caught up on our patchsets for Exadata. The most current bundle patch releases are 4 and 5. After hearing about widespread problems with bundle patch 4 I decided BP5 was probably the best fit for us. I did a few searches and didn’t find any serious complications from BP5. However during the installation I did come across a couple of issues I thought I’d share here.
