很多用户都想了解Oracle RAC ,但是又缺少硬件条件来安装和了解RAC。这里我们应用Oracle VM，在XEN虚拟机上来实现安装。
Oracle VM于2007年11月12日正式推出,目前最新的版本是2.1.1。它是一款基于开源Xen管理器的虚拟化软件，支持Oracle和非Oracle的应用程序。在OTN 上可以免费下载到相关资源。用户可以在OVM中通过多种方式快捷地创建虚拟机和虚拟磁盘。
这里我们创建2台虚拟机作为集群里的2个节点。
·通过Oracle Virtual Machine Template创建虚拟机 RAC1_13 和 RAC2_13。
·虚拟机的内存至少为 1G
·每台机器应创建 2 块虚拟网卡，如下图所示：
Select
Virtual Network Interface Name
Virtual Network Interface MAC Address
Xen Bridge
Status
Network Interface
Select
VIF0
00:16:3E:2A:69:C6
xenbr0
Active
netfront
Select
VIF1
00:16:3E:37:80:7C
xenbr1
Active
netfront
·作为RAC节点的虚拟机的OS 版本应一致，这里我们都选择 Oracle Enterprise Linux Release 4 Update 5.
·创建完毕，“Power On”所有的节点。
2 安装Clusterware前的准备 2.1 检查系统硬件环境 (在所有节点上)系统硬件条件至少应满足
·1G RAM
# grep MemTotal /proc/meminfo·Swap 1.5G
# grep SwapTotal /proc/meminfo·/tmp >400MB
# df -k /tmp·650MB的磁盘空间作为Oracle Clusterware home
·1G磁盘空间用来放Oracle Clusterware file
如果考虑冗余的话，需要再增加分区
·至少4G磁盘空间作为Oracle Database home
·虚拟机的磁盘空间不够的话，可以通过增加虚拟磁盘的方法解决
2.2 配置和检查系统软件环境 (在所有节点上)检查系统是否已经安装以下的包
binutils-2.15.92.0.2-18elfutils-libelf-0.97-5
elfutils-libelf-devel-0.97.5
glibc-2.3.9.4-2.19
glibc-common-2.3.9.4-2.19
glibc-devel-2.3.9.4-2.19
gcc-3.4.5-2
gcc-c++-3.4.5-2
libaio-devel-0.3.105-2
libaio-0.3.105-2
libgcc-3.4.5
libstdc++-3.4.5-2
libstdc++-devel-3.4.5-2
make-3.80-5
通过模板创建的虚拟机，，OS可能没有安装全部需要的包。
用户在安装前请参照Oracle官方文档检查系统是否已经安装所需的包。
RAC2_13 eth0 10.182.108.88 eth1 192.168.0.12
·修改节点的/etc/hosts文件
127.0.0.1 localhost.localdomain localhost10.182.108.86 rac1_13.cn.oracle.com rac1_1310.182.108.87 rac1_13-vip.cn.oracle.com rac1_13-vip192.168.0.11 rac1_13-priv.cn.oracle.com rac1_13-priv
192.168.0.12 rac2_13-priv.cn.oracle.com rac2_13-priv10.182.108.88 rac2_13.cn.oracle.com rac2_13
10.182.108.89 rac2_13-vip.cn.oracle.com rac2_13-vip
·修改节点的hostname
vi /etc/sysconfig/network
设置节点的hostname分别为RAC1_13和RAC2_13。

When might a full table scan be faster than using an index in MySQL?
Apr 09, 2025 am 12:05 AM
Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.
Explain InnoDB Full-Text Search capabilities.
Apr 02, 2025 pm 06:09 PM
InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.
Can I install mysql on Windows 7
Apr 08, 2025 pm 03:21 PM
Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.
Difference between clustered index and non-clustered index (secondary index) in InnoDB.
Apr 02, 2025 pm 06:25 PM
The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
MySQL: Simple Concepts for Easy Learning
Apr 10, 2025 am 09:29 AM
MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
The relationship between mysql user and database
Apr 08, 2025 pm 07:15 PM
In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
Can mysql and mariadb coexist
Apr 08, 2025 pm 02:27 PM
MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
RDS MySQL integration with Redshift zero ETL
Apr 08, 2025 pm 07:06 PM
Data Integration Simplification: AmazonRDSMySQL and Redshift's zero ETL integration Efficient data integration is at the heart of a data-driven organization. Traditional ETL (extract, convert, load) processes are complex and time-consuming, especially when integrating databases (such as AmazonRDSMySQL) with data warehouses (such as Redshift). However, AWS provides zero ETL integration solutions that have completely changed this situation, providing a simplified, near-real-time solution for data migration from RDSMySQL to Redshift. This article will dive into RDSMySQL zero ETL integration with Redshift, explaining how it works and the advantages it brings to data engineers and developers.
