hi everyone. i am completely new to this blog so please correct me if i break any rules. we have a 15.5 ASE server using the process model (not threaded kernel).
we have a linux server with 20 cpus and 20 "sibling" cpus (hyperthreaded). on this box we have 4 ASE servers and 4 backup servers. the ASE servers are configured as follows:
../SB1DB02AR7_DS.cfg: max online engines = 10
../SB1DB02AR7_DS.cfg: number of engines at startup = 3
../SB1DB02BR7_DS.cfg: max online engines = 10
../SB1DB02BR7_DS.cfg: number of engines at startup = 4
../SB1DB02CR8_DS.cfg: max online engines = 10
../SB1DB02CR8_DS.cfg: number of engines at startup = 4
../SB1DB02DR8_DS.cfg: max online engines = 10
../SB1DB02DR8_DS.cfg: number of engines at startup = 4 15
i have a developer who wants me to add 2 more engines to on of the server bringing the total to 17 at startup. what i want to know is what to i have to consider with today's technologie to make this decision ? we used to just assume you can allocate as many engines as you want as long as you leave 1 for the each backup server and 1 for the OS. is this correct anymore ?
thanks
