在数据库在线备份的时候会与Load和ALTER TABLE <表名> ACTIVATE NOT LOGGED INITIALLY WITH EMPTY TABLE发生冲突导致这两种操作被挂起，而在MIS系统中数据库往往比较大（TB级别很常见），备份时候经常花费几个小时，甚至1天以上的时间。当我们急需上述两种操作的时候，就需要kill掉备份，一般步骤如下：http://www.cndba.cn/hbhe0316/article/131545http://www.cndba.cn/hbhe0316/article/131545

#1 找到备份连接
[db2inst1@limt bin]$ db2 list applications show detail|grep -i back
#2 force掉备份连接
[db2inst1@limt bin]$ db2 "force application(26)"
DB20000I  The FORCE APPLICATION command completed successfully.
DB21024I  This command is asynchronous and may not be effective immediately.

#找到Process ID of client application 
[db2inst1@limt bin]$ db2 get snapshot for application agentid 55|less

#这个时候再次查看备份连接就消失了
