Hi

I had 3 Node RAC on Solaris and I am facing one scenario very frequently where 
a select query start taking  too much time in execution. It take only few 
seconds but after some time it changed to few minutes. At this time if I flush 
Buffer Cache on all Node, it come back to same few seconds and then after some 
time, it changed back to same situation. Any expert comments as what can be 
issue here. Oracle 10.2.0.3. This RAC environment is running 3 Database sand 
the problem is only with one Database and so it is not linked to interconnect 
which can give this issue. Also Select is only bringing few records and not 
high number of records

TIA
Sanjay
