Stopping DB2 Fault Monitor :.......Success
ERROR: The installFixPack command detected some DB2 libraries are still loaded
in memory and some applications might still be running in the current
installation copy.  All applications must be stopped. See the fix pack readme
for pre-installation instructions, and re-run the installFixPack command.
Alternatively, to override automatic checking, you can re-issue the
installFixPack command with the '-f db2lib' parameter. Note: If you re-issue
the installFixPack command with the '-f db2lib' parameter, after the DB2
instances are updated, some applications might not work properly and might need
to be restarted to function properly against the updated DB2 instance.

7.补充说明
1)在升级数据库前需要做好数据库和软件备份
2)升级过程时先关闭所有db2相关进程,如果不能正常关闭(非本文上面列举操作相关进程),直接kill
3)升级过程中,如果实例,DAS等升级失败,需要后续手工升级
4)检查相关进程,如果没有正常启动,需要手工给予启动
5)一些工具进行绑定和重新绑定packages
