Oracle Linux 配置 UDEV SCSI Rules 说明

Oracle RAC中ASM 的配置可以有2种方式实现:raw和asmlib。 在实际的维护中,更推荐使用raw。

使用raw又有两种方法:使用multipath和UDEV。在RedHat 平台下参考:

Redhat 5.4 +ASM + RAW+ Oracle 10g RAC 安装文档

对于ASMLIB,参考:

RAW+ASM 的RAC 安装文档

这篇看一下Oracle Linux 系统下UDEV的配置。

参考文档:

我这里的实验平台是Oracle Linux 6.1+Virtual Box。

Oracle Virtual Box 安装使用 说明 

一.准备工作

1.1   创建共享磁盘

这里直接使用VirtualBox命令来创建。 创建之前需要先关闭虚拟机。

F:\VBox\sharedisk

1.1.2 创建虚拟介质

C:\Users\Administrator.DavidDai>cdF:\VBox\sharedisk

C:\Users\Administrator.DavidDai>F:

F:\VBox\sharedisk>VBoxManage createhd --filename asm01.vdi --size 5120 --format VDI --variant Fixed

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Disk image created. UUID:83552343-5254-4fe0-8f4d-949389a4d528

F:\VBox\sharedisk>VBoxManage createhd --filename asm02.vdi --size 5120 --format VDI --variant Fixed

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Disk image created. UUID:b96d5ecb-168a-4eaf-851e-0f21961dae4e

 

F:\VBox\sharedisk>VBoxManage createhd --filename asm03.vdi --size 5120 --format VDI --variant Fixed

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Disk image created. UUID:fd7bba6c-9530-433f-a7e0-24d470ba1fb9

 

F:\VBox\sharedisk>VBoxManage createhd --filename asm04.vdi --size 5120 --format VDI --variant Fixed

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Disk image created. UUID:3239ed0d-bd0b-4124-a389-db21ecbb15db

 

 

1.1.3 将虚拟介质匹配到虚拟机上

 

F:\VBox\sharedisk>VBoxManage storageattach OraLinuxRAC1 --storagectl "SATA 控制器" --port 1 --device 0 --type hdd --medium asm01.vdi --mtype shareable

 

F:\VBox\sharedisk>VBoxManage storageattach OraLinuxRAC1 --storagectl "SATA 控制器" --port 2 --device 0 --type hdd --medium asm02.vdi --mtype shareable

 

F:\VBox\sharedisk>VBoxManage storageattach OraLinuxRAC1 --storagectl "SATA 控制器" --port 3 --device 0 --type hdd --medium asm03.vdi --mtype shareable

 

F:\VBox\sharedisk>VBoxManage storageattach OraLinuxRAC1 --storagectl "SATA 控制器" --port 4 --device 0 --type hdd --medium asm04.vdi --mtype shareable

 

几点注意的地方:

(1)    控制器名称

我这里写的是:"SATA控制器",因为我的虚拟机是中文显示的,如下图:

 


如果是英语的,,这里名称就要写成:"SATA Controller",如:

F:\VBox\sharedisk>VBoxManagestorageattach OraLinuxRAC1 --storagectl "SATA Controller" --port 1--device 0 --type hdd --medium asm04.vdi --mtype shareable

 

(2)storageattach 对应的是VM中显示的虚拟机的名称,我这里OraLinuxRAC1.

 

(3)如果要将磁盘加到其他的节点上,只需要更改这里的虚拟机名称即可。如:

F:\VBox\sharedisk>VBoxManagestorageattach OraLinuxRAC2 --storagectl "SATA 控制器" --port 1 --device 0 --typehdd --medium asm04.vdi --mtype shareable

MySQL's Role: Databases in Web Applications MySQL's Role: Databases in Web Applications Apr 17, 2025 am 12:23 AM

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

Explain the role of InnoDB redo logs and undo logs. Explain the role of InnoDB redo logs and undo logs. Apr 15, 2025 am 12:16 AM

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL vs. Other Programming Languages: A Comparison MySQL vs. Other Programming Languages: A Comparison Apr 19, 2025 am 12:22 AM

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages ​​such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages ​​have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

How does MySQL index cardinality affect query performance? How does MySQL index cardinality affect query performance? Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

MySQL for Beginners: Getting Started with Database Management MySQL for Beginners: Getting Started with Database Management Apr 18, 2025 am 12:10 AM

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

MySQL vs. Other Databases: Comparing the Options MySQL vs. Other Databases: Comparing the Options Apr 15, 2025 am 12:08 AM

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

Explain the InnoDB Buffer Pool and its importance for performance. Explain the InnoDB Buffer Pool and its importance for performance. Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

MySQL: Structured Data and Relational Databases MySQL: Structured Data and Relational Databases Apr 18, 2025 am 12:22 AM

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.
