Hi all, I have encountered mixed opinions regarding which scheduler is better for OLTP databases (mainly: Oracle). Solaris Internals site http://www.solarisinternals.com/wiki/index.php/FX_For_Databases http://www.solarisinternals.com/wiki/index.php/Application_Specific_Tuning#Tuning_Recommendations recommends using FX for databases. However http://blogs.sun.com/travi/entry/database_scaling_on_sun_fire says: "We also tried different scheduling classes. FX as well as RT but noticed that at even at high throughput the default TS scheduling class performs the best.".
While the former says in general the latter is strictly for CMT cpu. But I don't belive (am I wrong ?) that it depends on cpu type. Can anybody share his/her experience with changing scheduler for OLTP (Oracle ?) databases ?
