在Oracle Linux 5 和6上使用UDEV SCSI Rules配置ASM
UDEV ASMDisk 配置 因为Oracle 不出支持 RHEL6 系列的 ASMLib,所以我们可以改为 Udev 的方式配置ASMDisk,
UDEV ASMDisk 配置
因为Oracle 不出支持 RHEL6 系列的 ASMLib,,所以我们可以改为 Udev 的方式配置ASMDisk,详细如下:
优先使用udev 的方式配置ASM存储的块设备信息。
1.确认udev包已安装
[root@rac01 ~]# rpm -qa | grep udev
udev-147-2.40.el6.x86_64
2.获得硬盘WWID系统信息
(1) Oracle Linux 5 用如下命令
[root@rac01 ~]# /sbin/scsi_id -g -u -s /block/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_
[root@rac01 ~]# /sbin/scsi_id -g -u -s /block/sdc
SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_
[root@rac01 ~]# /sbin/scsi_id -g -u -s /block/sdd
SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_
[root@rac01 ~]# /sbin/scsi_id -g -u -s /block/sde
SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_
(2) Oracle Linux 6 用如下命令
[root@rac01 ~]# /sbin/scsi_id -g -u -d /dev/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_
[root@rac01 ~]# /sbin/scsi_id -g -u -d /dev/sdc
SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_
[root@rac01 ~]# /sbin/scsi_id -g -u -d /dev/sdd
SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_
[root@rac01 ~]# /sbin/scsi_id -g -u -d /dev/sde
SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_
3.对/dev/sdb 4G的硬盘分2个主分区,每个区2G,以实现OCR信息的冗余
[root@rac01 ~]# fdisk /dev/sdb
4.对/dev/sdc 8G的硬盘分4个逻辑个,每个区2G,以存储数据文件
[root@rac01 ~]# fdisk /dev/sdc
5. 配置udev配置文件
重要:每个配置文件一行为一条规则,并且,(逗号)与下一个关键词之间有空格。
[root@rac01 ~]# cd /etc/udev/rules.d/
[root@rac01 rules.d]# vi 99-oracle-asmdisk.rules

6. 确认配置正常,块设备的权限正确
# cd /dev
# ls -al asm-disk*
brw-rw—- 1 grid asmadmin 8, 17 Apr 8 22:47 asm-disk1
brw-rw—- 1 grid asmadmin 8, 33 Apr 8 22:47 asm-disk2

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.

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 is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

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.

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 is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.
