RAC en un CentOS 5.2 , baratito tambien

en los ficheros de /etc/udev/rules.d:

[root@localhost rules.d]# more 60-raw.rules
# This file and interface are deprecated.
# Applications needing raw device access should open regular
# block devices with O_DIRECT.
#
# Enter raw device bindings here.
#
# An example would be:
#   ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N"
# to bind /dev/raw/raw1 to /dev/sda, or
#   ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"
# to bind /dev/raw/raw2 to the device with major 8, minor 1.
ACTION=="add", KERNEL=="sda9",  RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sda10", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sda5",  RUN+="/bin/raw /dev/raw/raw3 %N"

$ ./runInstaller -ignoreSysPrereqs

antes de ejecutar ./rootsh cambiar los scripts (en caso contrario da un error de libpXXXX que no la encuentra)
This is a bug when you run RAC 10gR2 on RHEL5

The solution is remove the LD_ASSUME_KERNEL setting from the following files:
$ORA_CRS_HOME/bin/vipca
$ORA_CRS_HOME/bin/srvctl

vipca

tambien en vipca si vemos:
Error 0(Native: listNetInterfaces:[3]) 
[Error 0(Native: listNetInterfaces:[3])] 

As per the same note above, on raclinux2 execute the following from the CRS bin directory as root: 

./oifcfg setif –global eth0/192.168.0.0:public       
./oifcfg setif –global eth1/10.10.10.0:cluster_interconnect   

para evitarnos problemas, configurar el NIC con 3 IP privadas y configurar los interfaces asi:
 [root@rac1 network-scripts]# more ifcfg-eth0:1
# Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+
DEVICE=eth0:1
HWADDR=00:A0:C5:B4:48:4F
ONBOOT=yes
NETMASK=255.255.0.0
IPADDR=10.15.65.146

[root@rac1 network-scripts]# more ifcfg-eth0
