I don't think that the time for a query to fail over is equivalent to the time that CRS requires to identify the instance failure. As you don't have a database yet, I'd recommend actually trying it before getting too caught up in what "might" happen.

I installed two machine with RedHat AS 4Up5 and Oracle 10.2.0.3 with ClusterWare. The installation finish with successful and the data base work fine.I checked my environment of availability with the test below:Station cambeba UPStation cangua UP# crs_stat -tName Type Target State Host
------------------------------------------------------------
ora....BA.lsnr application ONLINE ONLINE cambeba
ora....eba.gsd application ONLINE ONLINE cambeba
ora....eba.ons application ONLINE ONLINE cambeba
ora....eba.vip application ONLINE ONLINE cambeba
ora....UA.lsnr application ONLINE ONLINE cangua
ora.cangua.gsd application ONLINE ONLINE cangua
ora.cangua.ons application ONLINE ONLINE cangua
ora.cangua.vip application ONLINE ONLINE cangua
ora.ora10gq.db application ONLINE ONLINE cangua
ora....q1.inst application ONLINE ONLINE cangua
ora....q2.inst application ONLINE ONLINE cambebaAt this point, that's ok, but when I force a power off in cangua or cambeba (the name of my machines), the time to the firt machine detect the second machine powered off is very big (between 1 and 2 min), so, if my client was working, will lost the query for time out.I changed the configurations in objects ora.cambeba.vip and ora.cangua.vip, but without successful.Any Ideia to fix this problem (decrease the time of check between nodes on cluster) ?!?!PS: I checked in list database, but without successful about this problem
Thanks in advanced.
