Home -> Community -> Mailing Lists -> Oracle-L -> RE: What block size are you using for your new 9i data warehouse?
Cherie:
If you are using Oracle 9i, you can use mutliple block sizes! You still create your database with a default block size, but each tablespace (except system) can have a block size different from the default.
Valid blocksizes are limited by OS, but they range from 2K to 32k.
Check out the 9i docs for CREATE TABLESPACE for more info.

We are building a new version 9.0.1 data warehouse on Sun Solaris 2.6 migrating to Solaris 2.8. We will be using striped disk that is striped using Veritas Volume Manager on EMC disk.
The datawarehouse will be about 200 Gig. It will be written to throughout the day.
To this point, almost all of our databases have been created with an 8k block size. i'm not sure if that blocksize is optimal anymore. With 9i, what block sizes are people using in the field nowadays for data warehouses?
Also, if you use striped disk, what stripe size are you using and why?
Thanks for weighing in on this topic.
