Google了一下，發現這是Oracle11.2.0.2.0以後的一個“特性”：
从oracle 11.2.0.2.0开始，控制文件的快照文件必须能够被所有节点的数据实例访问到，并且必须放在共享的位置。否则，使用RMAN进行备份控制文件的时候会报如下错误：
ORA-00245: control file backup operationfailed。
当使用备份脚本备份的时候，，这个错误可能会导致备份工作中断。
METALINK 中的两篇文档：
RAC BACKUP FAILS WITH ORA-00245: CONTROLFILE BACKUP OPERATION FAILED [ID1268725.1]【這篇文字沒找到】
RMAN Snapshot Controlfile Must Reside onShared Device for RAC database in 11G [ID 1263621.1]【這篇文字沒找到】
解释并解决了此问题！摘要如下：
"RMAN creates a copy of the controlfile for read consistency, this is the snapshot controlfile. Due to the changesmade to the controlfile backup mechanism in 11gR2 any instances in the clustermay write to the snapshot controlfile. Therefore, the snapshot controlfile fileneeds to be visible to all instances.
The same happens when a backup of thecontrolfile is created directly from sqlplus any instance in the cluster maywrite to the backup controfile file.
In 11gR2 onwards, the controlfile backuphappens without holding the control file enqueue. For non-RAC database, thisdoesn't change anything.
But, for RAC database, the snapshotcontrolfile location must be in a shared file system that will be accessible fromall the nodes."
当前的控制文件配置：
RMAN> show all;
using target database control file insteadof recovery catalog
RMAN configuration parameters for databasewith db_unique_name OSDB are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1;# default
CONFIGURE BACKUP OPTIMIZATION OFF; #default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; #default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; #default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FORDEVICE TYPE DISK TO '%F'; # default

CONFIGURE ARCHIVELOG DELETION POLICY TONONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO'/soft/product/11.2.0.2/dbh/dbs/snapcf_osdb1.f'; # default
由於我們使用的是ASM，所以可以使用如下配置解决此问题，也可以把ASM替換成共享目錄：
RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO'+SFRA/sncforcl_osdb.ora';
new RMAN configuration parameters:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+SFRA/sncforcl_osdb.ora';
new RMAN configuration parameters aresuccessfully stored
RMAN> show all;
RMAN configuration parameters for databasewith db_unique_name OSDB are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1;# default

How does Go language implement the addition, deletion, modification and query operations of the database?
Mar 27, 2024 pm 09:39 PM
Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.
How does Hibernate implement polymorphic mapping?
Apr 17, 2024 pm 12:09 PM
Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.
iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos
Jul 18, 2024 am 05:48 AM
Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

An in-depth analysis of how HTML reads the database
Apr 09, 2024 pm 12:36 PM
HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

Tips and practices for handling Chinese garbled characters in databases with PHP
Mar 27, 2024 pm 05:21 PM
PHP is a back-end programming language widely used in website development. It has powerful database operation functions and is often used to interact with databases such as MySQL. However, due to the complexity of Chinese character encoding, problems often arise when dealing with Chinese garbled characters in the database. This article will introduce the skills and practices of PHP in handling Chinese garbled characters in databases, including common causes of garbled characters, solutions and specific code examples. Common reasons for garbled characters are incorrect database character set settings: the correct character set needs to be selected when creating the database, such as utf8 or u
