试图将当前的物理STANDBY数据库切换为PRIMARY数据库时,出现下面的错误:
SQL> CONN SYS/TEST@TESTRAC_STANDBY AS SYSDBA
从报错的trace文件中,,可以看到下面的内容:
Metalink虽然指出了问题和RECOVERY AREA有关,但是并没有给出相应的解决方法,而且Oracle目前的版本还没有fixed这个bug,目前也没有任何补丁可以解决这个bug。
SQL> CONN SYS/TEST@TESTRAC2 AS SYSDBA
数据库已更改。
SQL> ALTER DATABASE OPEN;
数据库已更改。
SQL> SELECT DATABASE_ROLE FROM V$DATABASE;
下面将从库恢复:
SQL> CONN SYS/TEST@TESTRAC_STANDBY AS SYSDBA
数据库已更改。
SQL> SELECT DATABASE_ROLE, SWITCHOVER_STATUS FROM V$DATABASE;
至此DATA GUARD环境恢复。
下面DISABLE主库的RECOVERY AREA:
SQL> ALTER SYSTEM SET DB_RECOVERY_FILE_DEST = '';
系统已更改。
SQL> SHOW PARAMETER DB_RECOVERY
仔细查看从库上的错误信息,ORA-600错误的第一个参数是一个日志文件名,而这个文件正是RECOVERY AREA的日志:

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.

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.

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.

Article discusses strategies for handling large datasets in MySQL, including partitioning, sharding, indexing, and query optimization.

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.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
