需要重启Tuxedo应用时，提示：LIBTUX_CAT:577: ERROR: Unable to register because the slot is already owned
此时执行tmadmin命令，有报错：
$ tmadmin
tmadmin - Copyright (c) 1996-1999 BEA Systems, Inc. Portions * Copyright 1986-1997 RSA Data Security, Inc. All Rights Reserved. Distributed under license by BEA Systems, Inc. Tuxedo is a registered trademark. TMADMIN_CAT:199: WARN: Cannot become administrator.Limited set of commands available.
从上面两个提示看，可能有其他用户正在使用tmadmin操作，导致此用户session登录后无法执行这些高级别命令。
进一步使用w命令，看是否有这样的用户操作：
v490e5-tux:/opt/app/tuxapp/gateway/config$ w
1:29pm up 354 day(s), 1:57, 3 users, load average: 0.02, 0.03, 0.04
User tty login@ idle JCPU PCPU what
root console 7Jul14354days -sh
tuxapp pts/2 1:14pm tmadmin
tuxapp pts/3 1:28pm tmadmin
确实如此，有其他用户session正在做指令。
此时停止所有服务会报错：
tmshutdown -y;
Shutting down all admin and server processes in /app/app/etc/tuxconfig
Shutting down server processes ...
Shutting down admin processes ...
Server Id = 0 Group Id = SITE1 Machine = SITE1:
CMDTUX_CAT:1668: WARN: Cannot shutdown BBL on SITE1. Clients and/or servers may be running
CMDTUX_CAT:949: WARN: Shutdown failed
0 processes stopped.
必须使用强制命令：tmshutdown -c -y
这样就可以停止所有Tuxedo服务，再做其他操作。
