如何让我的 Java 应用程序在连接时向 Oracle 标识自己?

How do I make my Java application identify itself to Oracle on connection?(如何让我的 Java 应用程序在连接时向 Oracle 标识自己?)

问题描述

当我的应用程序连接到 Oracle 数据库时，我希望能够通过查看它所连接的数据库中的活动会话来查看.目前它将自己标识为JDBC 瘦客户端"，因为这是我正在使用的驱动程序，但我拥有的其他基于 Java 的应用程序能够以某种方式将此值设置为更有意义的值，例如SQL Developer".我认为它是 Connection 或 OracleDataSource 的一个属性，但我还没有找到一个可以解决问题的方法.这可能吗?以防万一，我使用的是 Java 1.5、Oracle 10g 和 10g 瘦驱动程序.

When my application connects to an Oracle database I want to be able to see by looking at the active sessions in the database that it is connected. Currently it identifies itself as "JDBC Thin Client" because that's the driver that I'm using, but other Java based applications that I have are somehow able to set this value to something more meaningful, like "SQL Developer". I thought it was a property of the Connection or the OracleDataSource, but I've not managed to find one that does the trick. Is this possible? In case it matters, I'm using Java 1.5, with Oracle 10g and the 10g thin driver.

推荐答案

java.util.Properties props = new java.util.Properties();
props.setProperty("password","mypassword");
props.setProperty("user","myusername");
props.put("v$session.osuser", System.getProperty("user.name").toString());
props.put("v$session.machine", InetAddress.getLocalHost().getCanonicalHostName());
props.put("v$session.program", "My Program Name");
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
Connection conn=
    DriverManager.getConnection("jdbc:oracle:thin:@myhostname:1521:mysid", props);

SQL>select username,osuser,program,machine
from v$session
where username = 'ROB'; 

USERNAME  OSUSER       PROGRAM             MACHINE
--------- -----------  ------------------  -----------
ROB       rmerkw       My Program Name     machine

在应用程序级别，您可以使用以下方法在 v$session 中设置 client_info、module 和 action>:

At application level you can use the following methods to set client_info, module and action in v$session:

dbms_application_info.set_client_info
dbms_application_info.set_module
dbms_application_info.set_action
