Resetting autocommit to false on JDBC Connection

我理解您的问题是关于在 JDBC 连接上将自动提交重置为 false。这意味着在执行 SQL 命令时，不会自动提交事务，而需要手动调用 commit() 方法进行提交。这样可以确保在执行多个 SQL 命令时，如果其中一个命令失败，则会回滚整个事务，避免不一致的数据状态。如果您有其他问题，请继续提问。

这段信息显示了一个SATA连接的故障。错误信息中指出了连接状态的改变和SATA链路的下降。此外，还显示了一个硬重置链接的操作和一个SATA链路速度的限制。这种情况通常是SATA数据线不良或松动，或者硬件故障引起的。你可以尝试重新插拔SATA数据线或电源线来解决这个问题。如果问题仍然存在，可能需要更换设备或联系硬件维修人员。

Error while waiting for device: Timed out after 300seconds waiting for emulator to come online.

This error message indicates that the emulator is taking too long to start up and connect to the development environment. There are several possible reasons for this, including insufficient resources on the host machine, slow network connectivity, or issues with the emulator image itself.

To resolve this issue, you can try the following steps:

1. Check your system resources: Make sure that your computer has enough RAM and CPU power to run the emulator. Close any unnecessary applications that are running in the background to free up resources.

2. Restart the emulator: Try restarting the emulator and see if it connects to the development environment within the timeout window.

3. Check your network connectivity: Slow or unstable network connectivity can cause the emulator to take longer to start up. Try connecting to a different network or resetting your internet connection.

4. Use a different emulator image: If the issue persists, try using a different emulator image or version to see if that resolves the problem.

5. Increase the timeout value: If none of the above solutions work, you can try increasing the timeout value in the development environment settings to give the emulator more time to start up.
