TNS-12500: TNS:listener failed to start a dedicated server process

TNS-12500: TNS:listener failed to start a dedicated server process
Cause: The process of starting up a dedicated server process failed. The executable could not be found or the environment may be set up incorrectly.
Action: Turn on tracing at the ADMIN level and reexecute the operation. Verify that the ORACLE Server executable is present and has execute permissions enabled. Ensure that the ORACLE environment is specified correctly in LISTENER.ORA. The Oracle Protocol Adapter that is being called may not be installed on the local hard drive. Please check that the correct Protocol Adapter are successfully linked. If error persists, contact Oracle Customer Support.

TNS-12500：TNS：侦听器无法启动专用服务器进程,
.原因：启动专用服务器进程的过程失败。无法找到可执行文件，或者环境设置不正确。,
.操作：打开ADMIN级别的跟踪并重新执行操作。验证ORACLE Server可执行文件是否存在并启用了执行权限。确保在LISTENER.ORA中正确指定ORACLE环境。正在调用的Oracle协议适配器可能未安装在本地硬盘驱动器上。请检查正确的协议适配器是否已成功链接。如果错误仍然存??在，请联系Oracle客户支持。,
