半夜修改oracle实例名
刚从回龙观回来,现在是凌晨0:50,悲催的IT人开始干活了。一个两节点oracle11g做的rac,主机名分别是rac1,rac2,实例名分别是db4qg_1,db4qg_2,需要的效果是rac1
刚从回龙观回来,虚拟主机,现在是凌晨0:50,悲催的IT人开始干活了。
一个两节点oracle 11g 做的rac,主机名分别是 rac1,rac2 ,实例名分别是db4qg_1,db4qg_2,香港服务器,需要的效果是rac1节点启实例db4qg_1,rac2节点起db4qg_2,但实际运行时,却反了。现在为了做这个rac的dataguard,最好把它纠正过来。
步骤如下:
1、备份数据库及控制文件。我让其他人导出了一份,又用rman搞了一把。
2、确认一下当前实例运行的情况 srvctl status database -d db4qg ,美国空间,输出结果为:
Instance DB4QG_1 is running on node rac2
Instance DB4QG_2 is running on node rac1
3、分别关闭2个实例:
srvctl stop instance -d DB4QG -i DB4QG_2
srvctl stop instance -d DB4QG -i DB4QG_1
4、在两个节点的系统检查oracle进程是否被正常枪毙 ps aux | grep ora
5、修改实例名:
srvctl modify instance -d DB4QG -i DB4QG_1 -n rac1
srvctl modify instance -d DB4QG -i DB4QG_2 -n rac2
6、启动2个实例,把步骤3的stop换成start即可
7、检查修改后的实例运行情况,照搬第2步,嘿嘿,真如扳道工一样把它搬过来了。
记录这些,备忘之。

Data import method: 1. Use the SQLLoader utility: prepare data files, create control files, and run SQLLoader; 2. Use the IMP/EXP tool: export data, import data. Tip: 1. Recommended SQL*Loader for big data sets; 2. The target table should exist and the column definition matches; 3. After importing, data integrity needs to be verified.

To query the Oracle tablespace size, follow the following steps: Determine the tablespace name by running the query: SELECT tablespace_name FROM dba_tablespaces; Query the tablespace size by running the query: SELECT sum(bytes) AS total_size, sum(bytes_free) AS available_space, sum(bytes) - sum(bytes_free) AS used_space FROM dba_data_files WHERE tablespace_

Creating an Oracle table involves the following steps: Use the CREATE TABLE syntax to specify table names, column names, data types, constraints, and default values. The table name should be concise and descriptive, and should not exceed 30 characters. The column name should be descriptive, and the data type specifies the data type stored in the column. The NOT NULL constraint ensures that null values are not allowed in the column, and the DEFAULT clause specifies the default values for the column. PRIMARY KEY Constraints to identify the unique record of the table. FOREIGN KEY constraint specifies that the column in the table refers to the primary key in another table. See the creation of the sample table students, which contains primary keys, unique constraints, and default values.

Use the ALTER TABLE statement, the specific syntax is as follows: ALTER TABLE table_name ADD column_name data_type [constraint-clause]. Where: table_name is the table name, column_name is the field name, data_type is the data type, and constraint-clause is an optional constraint. Example: ALTER TABLE employees ADD email VARCHAR2(100) Add an email field to the employees table.

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

Oracle garbled problems can be solved by checking the database character set to ensure they match the data. Set the client character set to match the database. Convert data or modify column character sets to match database character sets. Use Unicode character sets and avoid multibyte character sets. Check that the language settings of the database and client are correct.

Oracle provides multiple deduplication query methods: The DISTINCT keyword returns a unique value for each column. The GROUP BY clause groups the results and returns a non-repetitive value for each group. The UNIQUE keyword is used to create an index containing only unique rows, and querying the index will automatically deduplicate. The ROW_NUMBER() function assigns unique numbers and filters out results that contain only line 1. The MIN() or MAX() function returns non-repetitive values of a numeric column. The INTERSECT operator returns the common values of the two result sets (no duplicates).

To create a user in Oracle, follow these steps: Create a new user using the CREATE USER statement. Grant the necessary permissions using the GRANT statement. Optional: Use the RESOURCE statement to set the quota. Configure other options such as default roles and temporary tablespaces.
