Hello Waldirio
>> the time to the first machine detect the second machine powered
off is very big (between 1 and 2 min),
How are you measuring this time? Are you checking alert log or are
you using DB connections to check it?
Can you also send crsd.log?
Further, refer $CRS_HOME/bin/racgvip and there are few parameters
such as check interval, restart attempts etc controlling behavior of VIP
failover too. Not sure, they are applicable when machine is rebooted
since heartbeat will fail before vip check..

Hello Friends
I'd like to ask about Oracle RAC in Linux environment. I installed
two machine with RedHat AS 4Up5 and Oracle 10.2.0.3 <http://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 UP
Station cangua UP
# crs_stat -t
Name 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 cambeba
At 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.
