修改Oracle默认的认证方式

Oracle默认的认证方式是OS认证,所以如果以安装oracle的账号登陆服务器,就不需要登录数据库,只要在服务器端不用输入用户名密码就可以以DBA权限登录数据库:
show user也可以看出,不管用什么登录都能通过,,并且都是SYS用户。
解决方法:
只要到下面目录下,修改sqlnet.ora文件中的SQLNET.AUTHENTICATION_SERVICES参数即可,下次登录的时候将不会再是ODS认证的了:
windows下如果将该参数设置为NTS或者ALL或者注释掉才可以使用OS认证,设置为NONE或者任何其他值都不能使用OS认证
linux下如果设置为ALL或者注释掉才可以使用OS认证,设置为任何其他值都不能使用OS认证。
现在看看效果:
另外,如果你需要赋给linux其他用户运行oracle的权限,那么可以这么做:
将用户添加到oinstall用户组下即可:
当然,还需要配置用户的环境变量:
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
#PATH=$PATH:$HOME/bin
export ORACLE_BASE=/home/oracle/oracle
export ORACLE_HOME=/home/oracle/oracle/product/10.2.0/db_1
export ORACLE_SID=orclsid
export PATH=$ORACLE_HOME/bin:$PATH
export TNS_ADMIN=$ORACLE_HOME/network/admin
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export LANG=AMERICAN_AMERICAN.ZHS16GBK
#export PATH

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())

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.

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

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.

PHP database connection guide: MySQL: Install the MySQLi extension and create a connection (servername, username, password, dbname). PostgreSQL: Install the PgSQL extension and create a connection (host, dbname, user, password). Oracle: Install the OracleOCI8 extension and create a connection (servername, username, password). Practical case: Obtain MySQL data, PostgreSQL query, OracleOCI8 update record.
