兔八哥从国外的一个网站上看到的这方面的内容：

首先用记事本创建一个ESRI.opt文件，具体路径：

Windows用户为：c:\Program Files\ESRI\License\ESRI.opt

UNIX用户为：
$ARCHOME/sysgen/ESRI.opt
$SDEHOME/sysgen/ESRI.opt

在文件中可以使用下面控制参数，其作用分别为：

EXCLUDE - deny a user access to a feature.
EXCLUDEALL - deny a user access to all features served by this vendor daemon.
GROUP - define a group of users for use with any options.
HOST_GROUP - define a group of hosts for use with any options.
INCLUDE - allow a user to use a feature.
INCLUDEALL - allow a user to use all features served by this vendor daemon.
LINGER - cause licenses to be held by the vendor daemon for a period after the application checks them in or exits.
MAX - limit usage for a particular feature/group - prioritizes usage among users.
MAX_OVERDRAFT - limit overdraft usage to less than the amount specified in the license.
NOLOG - turn off logging of certain items.
REPORTLOG - specify that a logfile be written suitable for use by the FLEXadmin End-User Administration Tool.
RESERVE - reserve licenses for a user.

下面就是一个Sample意义是拒绝兔八哥使用License，而为潇潇暮雨预留一个License许可。

#START
EXCLUDE ARC/INFO USER tubage
RESERVE 1 ARC/INFO USER xiaoxiaomuyu
#END

兔八哥知道的只有这么一点了，剩下的大家自己琢磨吧，祝好运啦！
