Installation guide

Workaround: Comment out the lines that set the LD_ASSUME_KERNEL variable

from the VIPCA and SRVCTL utilities. For the VIPCA utility alter the

$CRS_HOME/bin/vipca script commenting out lines 119 through 123 as

follows:

arch=’uname -m’

# if [ "$arch" = "i686" -o "$arch" = "ia64" -o "$arch" = "x86_64" ]

# then

# LD_ASSUME_KERNEL=2.4.19

# export LD_ASSUME_KERNEL

# fi

With the lines commented out, root.sh should be able to call VIPCA

successfully. Ensure that you do not to comment out line 118 which sets the arch

variable as that is needed by the script.

For the SRVCTL utility alter the $CRS_HOME/bin/srvctl and the

$ORACLE_HOME/bin/srvctl scripts commenting out lines 173 and 174 as

follows:

#Remove this workaround when the bug 3937317 is fixed

#LD_ASSUME_KERNEL=2.4.19

#export LD_ASSUME_KERNEL

6.9 Mapping of 127.0.0.2 to the Local Hostname

By default, the hostname of a machine is mapped to the IP address 127.0.0.2

through an entry in the /etc/hosts similar to the following on SUSE Linux

Enterprise Server 10:

127.0.0.2 test test.example.com

YaST does this to provide compatibility with earlier versions of the applications

that had problems running on desktops with dynamically assigned hostnames

from DHCP. This mapping may cause certain Oracle networking libraries to

encounter errors when they attempt to resolve the hostname of the machine. To

avoid these problems, the entry should be removed from the /etc/hosts file.

Note that several network related YaST utilities may add this entry back to the

file.
