new pricing strategy at Oracle

Friday Mar 02, 2007

Oracle seems to have updated their pricing (amazing what you can find when one forages around on google in this case "multicore pricing Oracle faq"). This all seems to have happened a couple of weeks ago, according the the dates on the documents, but I guess I missed it in other blogs or articles.

Full price list is at: http://www.oracle.com/corporate/pricing/pricelists.html

To help understand it on the left there is an FAQ, or if you want to see it directly: http://www.oracle.com/corporate/pricing/multicore_faq.pdf

An Oracle take on Windows vs. Linux

Wednesday Feb 28, 2007

Interesting preso on Linux, showing Windows beating it in performance. details at: www.oracle.com/technology/tech/dotnet/col/europe2006/ukoug_2006-best_practices_rac_on_64-bit_windows.ppt

"Load Test Windows 2003 v Red Hat 4.0 (64 bit)"
...here are my summary from their slides:

"RAC Stress Test (150-250 users)

MS Windows 16% more Transactions/Minute (TPM)
response times up to 50% faster on Windows
250 users: Linux 30% of sorts on disk vs. sorts in memory
Linux used 17%-40% more memory...
RAC User Load Tests (2500–4500 users)
3500 users, Windows 18% more TPM
4000 users, Windows TPM increased, Linux failed to complete
2500 users, response was 9%-33% faster on Windows
Linux used 5%-25% more memory"

I didn't know Oracle was really getting into deciding which OS to prefer?

Frequent Linux crashes drove customer to Solaris

Wednesday Feb 21, 2007

Sun-PostgreSQL win shows benefit of Solaris over Linux. Pretty interesting trends happening in open-source databases.

This also shows why you can't just look at over-optimized benchmarks link TPC-C, one needs to look at real factors in the datacenter. For TPC-C issues you see previous posts:

...and also some questionable(?) changes over time:
