5.7 extjob Executable Required Directory Permissions

To enable the extjob executable to locate required libraries, the

$ORACLE_HOME/lib directory and all of its parent directories must have

execute permissions for group and other.

5.8 Modifying a Virtual IP Address Node Application

Use the srvctl modify nodeapps command to modify the name, IP address,

or netmask of an existing virtual IP address (VIP) resource. Use the -A argument

to include the existing interfaces for the VIP:

srvctl modify nodeapps -n mynode1 -A 100.200.300.40/255.255.255.0/eth0

This issue is tracked with Oracle bug 4500688.

5.9 Raw Devices on Oracle Enterprise Linux and Red Hat Enterprise

Linux

Verify that an appropriate raw devices utility (util-linux) rpm is installed for

the update of the operating systems. For example, on Oracle Enterprise Linux 4.0

and Red Hat Enterprise Linux 4.0 (update 5),

util-linux-2.12a-16.EL4.23.x86_64 or later rpm should be installed. On

Oracle Enterprise Linux 5.0 and Red Hat Enterprise Linux 5.0,

util-linux-2.13-0.44.EL5.x86_64 or later rpm should be installed.

When you restart an Oracle Enterprise Linux 4.0, Oracle Enterprise Linux 5.0,

Red Hat Enterprise Linux 4.0, or Red Hat Enterprise Linux 5.0 system, raw

devices revert to their original owners and permissions by default. If you are

using raw devices with this operating system for your Oracle files, for example,

for ASM storage or Oracle Clusterware files, you need to override this default

behavior. To do this, add an entry to the /etc/rc.d/rc.local file for each

raw device containing the chmod and chown commands required to reset them

to the required values.

As an example, here are sample entries in a /etc/rc.d/rc.local file that

control the restart behavior of raw devices for two ASM disk files

(/dev/raw/raw6 and /dev/raw/raw7), two Oracle Cluster Registry files

(/dev/raw/raw1 and /dev/raw/raw2), and three Oracle Clusterware voting

disks (/dev/raw/raw3, /dev/raw/raw4, and /dev/raw/raw5):

# ASM

chown oracle:dba /dev/raw/raw6

chown oracle:dba /dev/raw/raw7

chmod 660 /dev/raw/raw6

chmod 660 /dev/raw/raw7

# OCR

chown root:oinstall /dev/raw/raw1

chown root:oinstall /dev/raw/raw2

chmod 660 /dev/raw/raw1

chmod 660 /dev/raw/raw2

# Voting Disks

chown oracle:oinstall /dev/raw/raw3

chown oracle:oinstall /dev/raw/raw4

chown oracle:oinstall /dev/raw/raw5

chmod 644 /dev/raw/raw3

chmod 644 /dev/raw/raw4

chmod 644 /dev/raw/raw5
