This topic wasn't originally between shared-everything and shared-nothing. .. >> No, you are reading too much into a Wikipedia entry. > > naahhh.. wikipedia is there for reference just like when your doing > your thesis you need reference too.. your original argument who *uses* > mysql clustering.. and i prove those companies are using it... but you > keep on injecting another irrelevant topic to keep this debate > longer.. No, you say they use it and they are happy and they have no problems. That's quite a stretch from the Wikipedia entry, that's far more than just referencing. Had you simply said "these companies use it" then that would be fine. .. > oracle acquired tangosol product in 2007 and dubbed it as oracle > coherence.. coherence is a shared infrastructure.. it is an > application server-level caching product.. sharing data between nodes > in a cluster via ram cache for frequently used data.. it bypass oracle > data buffers by sharing at the application server ... it is one of > your solution that RAC for certain applications.. My point is that you broadly labeling me as unable to understand shared-everything is erroneous. And your understanding of Oracle Coherence is very incomplete. You say I inject various topics to prolong the debate but the reality is that you can't resist taking personal digs at me. >> True.

I initially pointed out areas where it's simply not possible to move from MySQL to Oracle (lacking features). Then you come in and say shared-nothing is superior... that RAC exhibits negative scalability... that's where this prolonged debate began. -- Orlando Andico +63.2.976.8659 | +63.920.903.0335 _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List http://lists.linux.org.ph/mailman/listinfo/plug Searchable Archives: http://archives.free.net.ph
