Chapter 26.

Installing Oracle Database 10g

This Chapter will guide you through the process of installing an Oracle 10g Database.

26.1. Installing Oracle 10g on a Remote Linux Server

If you want to install Oracle on a remote server, then you need to relink X to your local desktop. The

easiest way to do this is to use the "X11 forwarding" feature of ssh. This means that you do not have

to run xhost and set the DISPLAY environment variable. Here is an example how to make use of the

X11 forwarding feature of ssh. Simply run the following command from your local desktop:

$ ssh -X oracle@oracle_remote_server_name

Now when you run any GUI tool on the remote server, it will automatically be linked to your local

desktop. If this is not working, verify that the ForwardX11 setting is not set to "no" in /etc/ssh/

ssh_config on the remote server:

su - root

# grep ForwardX11 /etc/ssh/ssh_config | grep -v "^#"

ForwardX11 yes

26.2. Installing Oracle 10gR2 Cluster Ready Services (CRS)

with MPIO

There is a bug installing Oracle 10gR2 CRS services using MPIO(Multipath I/O). The bug has been

reported to Oracle and the bug number and description states:

BUG 5005148 - CANNOT USE BLOCK DEVICES IN VOTING DISK AND OCR DURING 10G RAC INSTALLATION

This has been fixed in Oracle 11g.

Before attempting to install CRS, ensure that all firewalls are disabled:

service iptables stop

chkconfig iptables off

There are workarounds to successfully install CRS using MPIO. MPIO has to be disabled during

installation. After the Vipca portion of the CRS installation is complete, the MPIO can be turned back

on, restart CRS services. In the following examples using MPIO, friendly names are used for ease

of manageability. In this example Oracle 10g R2 CRS is using internal redundancy for the OCR and

VOTING disks.

Read /usr/share/doc/device-mapper-multipath-0.4.5/Multipath-usage.txt for more

information on configuring multipath.

First, determine which block devices will be associated with MPIO devices with your OCR or Voting

Disks and save the output to a log file.

# multipath -l > multipath.log
