ORA-00480用于表明连接空闲进程（LCK）失败
官方解释:
ORA-00480 LCKx process terminated with error
Cause: The LGWR, CKPT, or SMON processes detected an internal error and terminated abnormally.
Action: If this occurred during instance startup the instance may not be able to start. Try shutting down the machine and restarting it, or investigate the trace file while the instance is not running to get an idea of why the process terminated abnormally.
If it is not readily apparent why the process has terminated abnormally, contact your Oracle Support Services representative.
常见案例:
1、由于内存不足，以及加载程序段和逻辑对象有损坏，它可能导致连接空闲进程 (LCK*) 终止错误；
2、如果你使用标准维护方法，比如更新服务器，安装了新的硬件，或调整硬件设置，也会导致LCKX失败错误；
3、如果实例启动过程中出现这个错误，实例将无法完成启动。
正常处理方法及步骤:
步骤一：检查日志文件或跟踪文件，找出导致错误的原因。
步骤二：重新启动服务器。
步骤三：如果重启服务器不能解决问题，可能需要联系客服，排查问题。
