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.

如下，表a是数据库中已经存在的表，b是准备根据表a进行复制创建的表：
1、只复制表结构的sql
create table b as select * from a where 1<>1
2、即复制表结构又复制表中数据的sql
create table b as select * from a
3、复制表的制定字段的sql
create table b as select row_id ......

1.创建过程
与其它的数据库系统一样，Oracle的存储过程是用PL/SQL语言编写的能完成一定处理功能的存储在数据库字典中的程序。
语法:
create [or replace] procedure procedure_name
[ (argment [ { in| in out }] type,
argment [ { in | out | in out } ] type
{ is | as }
