db2stop force

当db2执行 db2stop force很长时间无反应时，很可能是：DB2 is hung

可以用db2start 或db2stop执行,可能会返回这样的错误：SQL6036N maybe seen when issuing db2stop or db2start, or the command may hang

解决方法：

In some cases, db2 will appear to be hung and will not respond to db2stop or db2start. The db2 commands will give the following message:

SQL6036N: START or STOP DATABASE MANAGER command is already in progress.

To force the db2 to shut down, open a db2 client command line window and issue:
db2_kill

Note: restarting the database or recycling the system may also resolve the issue.
