1. HP-UX 11i下使用net-snmp，如snmptrap程序，提示找不到动态库libnetsnmp.sl.6。SHLIB_PATH环境变量已经设置了也不行。
解决办法：用chatr命令检查snmptrap程序，发现首选使用的是静态链接库。用chatr命令更改优先查找SHLIB_PATH就好了，命令如下：
# chatr +s enable +b disable -l /path/to/lib/libnetsnmp.sl.6 snmptrap
2. 启动snmptrap时报错：

3. 安装Oracle时会出现一些类似下面的字符集警告信息，无关大局但令人不太舒服。
Warning: Missing charsets in String to FontSet conversion
Warning: Cannot convert string "-dt-interface system-medium-r-normal-s*-*-*-*-*-*-*-*-*" to type FontSet
Warning: Missing charsets in String to FontSet conversion
Warning: Cannot convert string "-dt-interface user-medium-r-normal-s*-*-*-*-*-*-*-*-*" to type FontSet
Warning: Cannot convert string "-dt-interface system-medium-r-normal-s*-*-*-*-*-*-*-*-*" to type FontSet
Warning: Missing charsets in String to FontSet conversion
Warning: Cannot convert string "-dt-interface user-medium-r-normal-s*-*-*-*-*-*-*-*-*" to type FontSet
解决办法：
$ export LC_CTYPE=C.iso88591
4. 使用ps命令时如何查看进程的其他信息？
使用如下命令可以返回指定的信息
# UNIX95= ps -eo 'vsz pid args' |sort -nr |head -20
# UNIX95= ps -e -o "user,pcpu,cpu,vsz,pid,ppid,args" | sort -rnk4
# UNIX95= ps -e -o "user,pcpu,cpu,vsz,pid,ppid,args" | sort -rnk4
5. 如何得到HostID？
# echo `/bin/uname -i` 16op | dc

6. 启动CDE时报错：
The desktop messaging system could not be started
原因：/etc/resolv.conf设置了DNS服务器，但没有/etc/nsswitch.conf文件。
解决方法：
# cp /etc/nsswitch.files /etc/nsswitch.conf
并修改/etc/nsswitch.conf，把
hosts: dns [NOTFOUND=return] nis [NOTFOUND=return] files
改成
hosts: files dns [NOTFOUND=return] nis [NOTFOUND=return]
