1.RMAN-04006 ORA-12528
将备库启动到nomount状态下
SQL> startup nomount

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00554: 内部恢复管理器程序包初始化失败
RMAN-04006: 来自辅助数据库的错误: ORA-12528: TNS: 监听程序: 所有适用例程都无法建立新连接
如上情况原因分析:由于备库的实例在nomount状态下,如果是动态注册监听器,那么在nomount状态下是不会注册监听的,所以需要配置静态注册
解决方法:配置静态监听,主库的tnsnames.ora如下:
#指向备库的连接字符串
TESTS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 188.188.3.20)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = TESTM)
)
)
备库的listener.ora中添加:
#备库添加静态注册
SID_LIST_LISTENER =(SID_LIST=(SID_DESC=(SID_NAME=TESTM)(ORACLE_HOME=/oracle/product/12.1.0)))
$ lsnrctl reload //重新加载listener.ora
$ lsnrctl status //查看状态
oracle@Sol_ORA:/oracle/12.1/network/admin$ rman target sys/test@TESTM auxiliary sys/test@TESTS //主库连接 故障排除

2.RMAN-06136: 来自辅助数据库的 ORACLE 错误: ORA-19847: 无法从远程站点读取控制文件的标头
原因:不详
解决方法:断开除主库的RMAN之外的所有备库的连接
3. RMAN-06136: 来自辅助数据库的 ORACLE 错误: ORA-01013: 用户请求取消当前的操作,原因是做duplicate时备库上还有用户登入,,退出登入后错误解决
原因:不详
解决方法:断开除主库的RMAN之外的所有备库的连接

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.

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

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.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

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.

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

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

Through the Go standard library database/sql package, you can connect to remote databases such as MySQL, PostgreSQL or SQLite: create a connection string containing database connection information. Use the sql.Open() function to open a database connection. Perform database operations such as SQL queries and insert operations. Use defer to close the database connection to release resources.
