The appropriate programming hardware setup will depend on the specific device you are programming. However, some general options for programming hardware setups include: USB-to-serial adapter, for devices that communicate over a serial port JTAG programmer, for devices with a JTAG interface ISP programmer, for devices with an In-System Programming interface SWD programmer, for devices with a Serial Wire Debug interface You should consult the device datasheet or reference manual to determine which programming hardware setup is appropriate for your device. Then, you can select the corresponding programming hardware setup in your programmer software. 翻译

适当的编程硬件设置取决于您正在编程的具体设备。然而，一些常见的编程硬件设置包括：适用于使用串行端口通信的设备的USB转串口适配器，适用于具有JTAG接口的设备的JTAG程序员，适用于具有In-System编程接口的设备的ISP程序员，适用于具有串行线调试接口的设备的SWD程序员。您应该查阅设备数据手册或参考手册，以确定哪种编程硬件设置适用于您的设备。然后，您可以在编程器软件中选择相应的编程硬件设置。

Vue has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

The error message you are seeing indicates a Cross-Origin Resource Sharing (CORS) issue. CORS is a browser security feature that prohibits web pages from making requests to a different domain than the one that served the page.

To resolve this issue, you have a few options:

1. Configure the server: You need to add the appropriate response headers to your server's responses to allow cross-origin requests. Specifically, you need to include the "Access-Control-Allow-Origin" header with the value of the requesting domain.

2. Use a proxy server: If you don't have control over the server's configuration, you can set up a proxy server that forwards requests from your domain to the target server. By doing this, the same-origin policy will be satisfied, and CORS won't be an issue.

3. Use a JSONP request: If the server supports JSONP (JSON with Padding), you can use it as an alternative. JSONP is a technique that allows making cross-origin requests by dynamically adding a ```<script>``` tag to the page.

Choose the appropriate solution based on your specific situation and server setup.

这个异常通常是由于数据库连接池中的可用连接数不足导致的。当连接池中没有可用的连接时，监听器将拒绝连接，并返回ORA-12519错误。要解决这个问题，你可以尝试以下几个步骤：

1. 检查数据库的最大连接数配置：确认数据库的最大连接数是否正确配置。你可以通过查询数据库的连接数限制参数来检查。

2. 检查数据库连接池配置：如果你在应用程序中使用了连接池，确保连接池的配置与数据库的最大连接数一致。

3. 检查数据库服务是否正常运行：确认数据库服务是否正在运行，并且可以接受新的连接请求。你可以通过尝试手动连接到数据库来验证。

4. 调整数据库连接数：如果数据库的最大连接数配置较低，并且你的应用程序需要更多的连接数，考虑增加数据库的最大连接数限制。

5. 检查网络连接：确认应用程序服务器和数据库服务器之间的网络连接是否正常。可能存在网络故障或防火墙配置问题导致连接被拒绝。

根据具体情况，你可以尝试以上方法来解决这个问题。如果问题仍然存在，你可能需要进一步检查数据库和应用程序的日志以获取更多信息来进行故障排除。
