FTP工具引起的一个低级错误的解决过程

问题描述：Aix操作系统，安装的Websphere Application Server 6.1 ND服务起，一共有5个server,将AppSer1进程用kill -9强杀时，会报进程不存在
CREDIT-WF-01(root)/ibm/was_app/WebSphere/AppServer/profiles/AppSrv01/logs/server1> more server1.pid
1126462
CREDIT-WF-01(root)/ibm/was_app/WebSphere/AppServer/profiles/AppSrv01/logs/server1> kill -9 1126462
kill: 1126462: 0403-003 The specified process does not exist.



问题解决：1.去bin目录下执行如下命令，报如下错误：
CREDIT-WF-01(root)/ibm/was_app/WebSphere/AppServer/profiles/AppSrv01/bin> ./startServer.sh server1java.lang.ClassNotFoundException: com.ibm.ws.management.tools.WsServerLauncher
        at java.net.URLClassLoader.findClass(URLClassLoader.java:496)
        at com.ibm.ws.bootstrap.ExtClassLoader.findClass(ExtClassLoader.java:132)

2.初步以为服务器没有加载一些类包，重启WAS也重启不了，于是做操作系统重启工作：
CREDIT-WF-01(root)/ibm/was_app/WebSphere/AppServer/profiles/AppSrv01/bin> shutdown -Fr

3.系统重启后，启动WAS时仍报同样的错误：java.lang.ClassNotFoundException: com.ibm.ws.management.tools.WsServerLauncher

查看AppSrv下的logs/server1下的日志，发现native_stderr.log日志914M，打开看，基本类似这样的异常记录：

class load: com.ibm.ws.management.event.NotificationService from: file:/ibm/was_app/WebSphere/AppServer/plugins/com.ibm.ws.runtime_6.1.0.jar
class load: com.ibm.ws.management.event.RemoteSender from: file:/ibm/was_app/WebSphere/AppServer/plugins/com.ibm.ws.runtime_6.1.0.jar

4.显然是加载/ibm/was_app/WebSphere/AppServer/plugins是目录下的jar文件出错，于是登录到该目录下，发现竟然没有在AppServer下竟然没有plugins，
依次查看路径，发现profiles下有一个plugins文件夹比较怪异，于是用mv -r * ../../plugins将其挪至AppServer下，再次启动WAS，OK。

O(∩_∩)O~， 不知是哪个衰人错误操作，将路径plugins文件夹挪了一下，让我折腾了这么长时间，获取到了这么多经验。
