TNS-12500 TNS:listener failed to start a dedicated server processCause: 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 re-execute 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. Check that the correct Protocol Adapter are successfully linked. If the error persists, contact Oracle Customer Support. 简要说明解决办法： 1、验证服务器进程存在，并且允许执行权限。 2、确定Oracle环境在Listener.ora中被正确的指定。 3、检查协议适配器是否正确安装。我又贴了一遍，看对贴主有没有帮助？
