Hmm,
I remember reading this requirement and at that time I decided that it
didn't apply (not at least in the last case I was talking about).
Now, after re-reading the MOS note and the documentation I'm not sure
about that...
If I understand the note correctly, after certain bugfix RAC systems
that use kernel 2.6.31+ and utilize multiple NICs
for the private interconnect, require specific settings for the
rp_filter parameter (and Oracle recommends
setting this parameter to 2).
The system I was talking about is using RHEL 5.7 with kernel 2.6.18.
Multiple bonded NICs are used for the Interconnect
If I remember correctly, on those systems rp_filter was set to 1 for all
NICs (I don't know if this is a default setting
for this OS and kernel or someone manually set it after the OS has been
installed).
So should it be changed to 2 on a system that uses kernel 2.6.18 when
multiple NICs in bonding are used
for the Interconnect?
Best regards
Dimitre
