在rs6000(aix5.1)安装db2数据库，数据库用户db2inst1无法登录EXTRA,提示见附件，我安照提示修改db2$home/.dtprofile增加下面一行
export DT_TTSESSION_TIMEOUT=120
重新登录依然失败。

这个是老问题，用户不能登录CDE
你别的用户登录有问题不，把db2inst的。profile贴出来看看
另外就是你的/etc/hosts
主要检查你的网络设置

提问题的时候为什么不首先在论坛里SEARCH一下？该问题曾经有过专门的讨论的。

对不起，我没有查询到。其他用户可以登录，下面是db2inst1用户的.profile
set vi -r
PATH=/usr/lpp/cics/bin/:/usr/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:.

export PATH

if [ -s "$MAIL" ] # This is at Shell startup. In normal
then echo "$MAILMSG" # operation, the Shell checks
fi # periodically.

# The following three lines have been added by UDB DB2.
if [ -f /home/db2inst1/sqllib/db2profile ]; then
. /home/db2inst1/sqllib/db2profile
fi

1. 贴出/home/db2inst1/sqllib/db2profile
2. 贴出/home/db2inst1/.dt/startlog

好像这个dtprofile有问题，因为是执行了.profile并由它调用dtprofile后才执行dtsession的，只有这个用户启动dtsession有问题，说明和.profile也就是dtprofile有关，应该是环境变量被dtprofile搞出问题了。
我试了试，dtprofile的模块AddtoString会将原来的环境变量内容删除再加上指定的内容，而其作用应该是在原有的后面加：

OO=/pp
./uu
执行结果是
:888
而正常应该是
/pp:888

我无法解决这个问题,请求帮助.

我无法解决这个问题,请求帮助.

由看了看，我搞错，试验的时候应当把OO=/pp放在脚本里就没问题。
最好把dtprofile从.profile里拿掉，看能否登录进CDE

不能登录，谁有高招？
