环境:CentOS 6.4 64bit、grid 64bit、oracle11g 64bit
简述:
安装grid之前,手工进行环境检验,如下提示需要执行runfixup.sh脚本,以下将此
过程展现如下:
[grid@test1 grid]$ ./runcluvfy.sh stage -pre crsinst -n test1,test2 -fixup –verbose
--对两个节点进行安装grid检验
......
......
......
Check: Time zone consistency
Result: Time zone consistency check passed
Fixup information has been generated for following node(s):
test2,test1
Please run the following script on each node as "root" user to execute the fixups:
'/tmp/CVU_11.2.0.3.0_grid/runfixup.sh'
Pre-check for cluster services setup was unsuccessful on all the nodes.
[root@test1~]# /tmp/CVU_11.2.0.3.0_grid/runfixup.sh
--在节点1上执行脚本
Response file being used is :/tmp/CVU_11.2.0.3.0_grid/fixup.response

[root@test2 ~]# /tmp/CVU_11.2.0.3.0_grid/runfixup.sh
--在节点2上执行脚本
Response file being used is :/tmp/CVU_11.2.0.3.0_grid/fixup.response

uid=501(grid) gid=501(oinstall) groups=501(oinstall),502(dba),503(asmadmin),504(asmdba),505(asmoper)
将脚本执行完后,该提示不再出现,接下来顺利安装grid即可。

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.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

MySQL is suitable for beginners because: 1) easy to install and configure, 2) rich learning resources, 3) intuitive SQL syntax, 4) powerful tool support. Nevertheless, beginners need to overcome challenges such as database design, query optimization, security management, and data backup.

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
