DB2 DOUBLES THE PERFORMANCE OF ORACLE 10G
Posted in 2004
Not a support question but a marketing/benchmark flame thread: someone posted an IBM page claiming DB2 doubles the performance of Oracle 10g RAC on a 1TB TPC-H test. Posters picked it apart, noting the comparison used different CPUs (1.7GHz POWER4+ with 128MB L3 vs 1.3GHz Itanium2), different operating systems, and that IBM's graph omitted three higher 1TB results listed on tpc.org. Side discussions covered XPS lacking TPC-friendly features (e.g. materialized views) and shared-nothing vs shared-everything failover. Ends in IBM/Oracle sniping with no conclusion or resolution.

Different CPU architectures Different Operating Systems. Like we can compare that! Oracle: Processors: 16 x Itanium2 1.3GHz, 32KB L1-cache, 256KB L2-cache, 3MB L3-cache IBM: Processors 4 x 1700MHz POWER4+ with 128MB L3 Cache So Oracle has 48Mb cache on the CPU and IBM has 128Mb! Try again..this time for the same OS...On the same hardware! Then we can take the pi*s! You're not going to throw a strop at me are you?

>> DB2 Doubles the Performance of Oracle 10g RAC That's an amazing trick, isn't it? So you buy Oracle 10g, then just buy DB2, and magically your Oracle 10g performance doubles?

Nah... XPS was cool... but it's not relevant anymore. Too bad. Great set of tools for that one. Keeping in mind who DB2 has to really compete against, those bench marks are sweet!

Basically DJ would pull the data back and hash join, which was faster than the NLJ being done in Oracle. And Oracle was not doing hash joins, because, believe it or not, in the example scenario, the database had been set up not to do them. Wonder why ? The IBM web page is also a little selective in the benchmarks it's using for comparison. Check out the rest of the 1 TB results at http://www.tpc.org/tpch/results/tpch_perf_results.asp?resulttype=all There are actually three higher results NOT show on the graph (and I wonder who has them) > Gawd-I-just-love-this-shit I do believe Tim's categorization is right.

What happens when you pull the plug on one of those shared nothing nodes as compared to one of Oracle's shared everything nodes? What is the throughput?

Hardware failures only happens to the other guy. Certainly not people using the top-ranking Siemens hardware. Siemens have a great reputation over here in England-land for the quality of their government IT projects. Who remembers the eight-hour queues for a passport of a couple of summers ago ... ?

This is the second time in a couple of weeks where you seem to be certain to know what I talk about. In neither case did you hit it on the nose.

Why do I have the feeling that two of them are dups? That each of them uses 4 times the number of CPU's to get 50% more juice, and none of them uses RAC, but instead a big SMP box. I recently saw an ad on that topic....onDemand vs Grid. Can't quite put my finger on it. Cheers Serge Serge Rielau DB2 SQL Compiler Development IBM Toronto Lab

I was thinking about materialized views, and sometime ago I've read or heard about a DB2 feature where one query could hook up to an already running query (similar or identical queries...?) Ok... this last one seems weird... I'm confused... forget it. Regards.

You throw in another 4way in standby....oh yes.. you never accepted that proposition in the past but never explained why. Why?

I must have just taken leave of my senses (well, alright, again.) I could have sworn someone from Oracle was claiming the moral high ground in the benchmark war and sounding aggrieved in the process...? -- "C'est pas parce qu'on n'a rien ''' dire qu'il faut fermer sa gueule" - Coluche
