RMAN备份时遇到ORA-19588
客户反映NBU备份任务失败，检查RMAN备份脚本的日志输出发现是由于ORA-19588导致备份任务终止，
客户反映NBU备份任务失败，检查RMAN备份脚本的日志输出发现是由于ORA-19588导致备份任务终止，具体报错如下：
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on ch00 channel at 07/15/2015 11:51:47
ORA-19588: archived log recid 125609 stamp 884484359 is no longer valid
错误的是由于备份期间某一个归档文件在控制文件中没有找到导致备份失败，可能导致这个错误的原因主要有3个:
1、控制文件信息与归档文件信息不一致，可以使用如下命令更新控制文件信息；
2、RMAN备份任务被启动了两次；
3、错误的备份脚本语法。
对于第1种错误，可以使用下面的命令对控制文件进行更新：
RMAN> crosscheck archivelog all;
对于第二种错误，需要检查备份任务的启动情况，，不要让RMAN备份任务重复启动，对于第三种错误，通常是在备份脚本中出现了如下的写法：
backup archivelog all archivelog until time 'sysdate -7' delete input ;
上面的脚本在RMAN中的执行过程是先备份所有的归档，然后删除归档，接着再执行备份直到sysdate-7的归档，所以执行第二步备份时会发现归档已经被删除了，就会出现ORA-19588错误。
检查备份脚本发现，crosscheck archivelog all已经写入到备份脚本中，所以排除第一种错误，在备份脚本中也没有发现第三种情况中的错误写法。所以怀疑NBU启动了两次备份任务，但是检查NBU日志发现，备份任务只启动了一次，但是有个奇怪的现象是针对这个系统有两个不同的备份任务，接下来检查两个备份任务的脚本，其中一个是对数据库进行全备，同时备份所有的归档文件和控制文件，另外一个备份脚本是备份所有的归档，并删除3天前的归档。两个备份脚本都涉及到对归档的操作，接下来检查两个任务的执行时间：
SQL> select START_TIME,END_TIME,STATUS,ELAPSED_SECONDS from V$RMAN_BACKUP_JOB_DETAILS order by START_TIME;
START_TIME END_TIME STATUS ELAPSED_SECONDS
------------------- ------------------- ----------------------- ---------------
2015-07-14 05:00:04 2015-07-14 07:20:31 COMPLETED 8427
2015-07-14 11:23:57 2015-07-14 11:25:27 FAILED 90
2015-07-14 11:33:34 2015-07-15 00:28:41 COMPLETED 46507
2015-07-14 16:59:36 2015-07-15 10:22:13 FAILED 62557
2015-07-15 00:31:01 2015-07-15 11:51:47 FAILED 40846
从上面的备份任务的起止时间分析，两个备份任务出现交叉，而且都涉及到对归档的操作，因此导致了ORA-19588。需要将两个备份任务的时间窗口进行重新分布，避免同一时间有两个备份任务执行。

When might a full table scan be faster than using an index in MySQL?
Apr 09, 2025 am 12:05 AM
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.
Explain InnoDB Full-Text Search capabilities.
Apr 02, 2025 pm 06:09 PM
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.
Can I install mysql on Windows 7
Apr 08, 2025 pm 03:21 PM
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.
Difference between clustered index and non-clustered index (secondary index) in InnoDB.
Apr 02, 2025 pm 06:25 PM
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: Simple Concepts for Easy Learning
Apr 10, 2025 am 09:29 AM
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 relationship between mysql user and database
Apr 08, 2025 pm 07:15 PM
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.
Can mysql and mariadb coexist
Apr 08, 2025 pm 02:27 PM
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.
Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial).
Apr 02, 2025 pm 07:05 PM
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.
