Environment variable ORACLE_UNQNAME not defined错误解决
Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.其实就是em的问题重新配
Environment variable Oracle_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.
其实就是em的问题重新配置emca即可。以后注意之前设置好ORACLE_UNQNAME 。
总结收藏:
1,修改DBSNMP密码:
重新配置DBCONSOLE,需要输入DBSNMP密码,但任何密码都会显示错误,需要预先修改。
alter user dbsnmp identified by xxx;
2,删除早期DBCONSOLE创建的用户:
drop role MGMT_USER;
drop user MGMT_VIEW cascade;
drop user sysman cascade;
3,删除早期DBCONSOLE创建的对象:
drop PUBLIC SYNONYM MGMT_TARGET_BLACKOUTS;
drop public synonym SETEMVIEWUSERCONTEXT;
drop public synonym MGMT_AVAILABILITY;
drop public synonym MGMT_CURRENT_AVAILABILITY;
drop public synonym MGMT_SEVERITY_OBJ;
4,重新创建DBCONSOLE:(如果是在windows下,要先到注册表删除DBCONSOLE(HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/OracleDBconsole)的服务,重启电脑)
$emca -config dbcontrol db -repos create;
如果此命令还是失败,,可直接利用重建命令:
$emca -config dbcontrol db -repos recreate;
根据提示,先输入SID,再输入Y继续;
输入端口1521,输入SYS密码,输入DBSNMP密码,输入SYSMAN 密码,输入Y继续
完成。
5,检查状态
emctl status dbconsole;
附emca常用命令:
创建一个EM资料库
emca -repos create
重建一个EM资料库
emca -repos recreate
删除一个EM资料库
emca -repos drop
配置数据库的 Database Control
emca -config dbcontrol db
删除数据库的 Database Control配置
emca -deconfig dbcontrol db
重新配置db control的端口,默认端口在1158
emca -reconfig ports
emca -reconfig ports -dbcontrol_http_port 1160
emca -reconfig ports -agent_port 3940
先设置ORACLE_SID环境变量后,启动EM console服务
emctl start dbconsole
先设置ORACLE_SID环境变量后,停止EM console服务
emctl stop dbconsole
先设置ORACLE_SID环境变量后,查看EM console服务的状态
配置dbconsole的步骤
emca -repos create
emca -config dbcontrol db
emctl start dbconsole
重新配置dbconsole的步骤
emca -repos drop
emca -repos create
emca -config dbcontrol db
emctl start dbconsole

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.

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.

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.

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 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 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.

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.

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.
