Upgrade Oracle 9i RAC to Oracle 10g RAC
Upgrade Oracle 9i RAC to Oracle 10g RAC
by Vincent Chan
This article provides the procedures for converting Oracle 9i (9.2.0.4) RAC to Oracle 10g (10.2.0.1) RAC on Red Hat Enterprise Linux 3 (RHEL3).
Oracle Database 10g and Oracle Real Application Cluster (RAC) 10g itself, boast many new and exciting features that simplify database manageability and provide higher availability and scalability. Compared to its predecessors, Oracle 10g RAC is much easier to install, use and manage, thereby reducing the total cost of ownership.
Overview
The RAC cluster comprises two Intel x86 servers running on RHEL3 (Kernel 2.4.21-27). Each node has access to a shared storage and connectivity to the public and private network.
This article is structured into the following steps:
1. Preliminary Installation
2. Install Oracle Clusterware
3. Install Oracle RAC Software
4. Upgrade the Database
5. Migrate Database to ASM (Optional Step)
Unless otherwise specified, you should execute all steps on both nodes.

对于外连接，Oracle中可以使用“(+)”来表示，9i可以使用LEFT/RIGHT/FULL OUTER JOIN，下面将配合实例一一介绍。
1. LEFT OUTER JOIN：左外关联
SELECT e.last_name, e.department_id, d.department_name
from employees e
LEFT OUTER JOIN department ......
