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：
#1 找到备份连接 [[email protected] bin]$ db2 list applications show detail|grep -i back #2 force掉备份连接 [[email protected] bin]$ db2 "force application(26)" DB20000I The FORCE APPLICATION command completed successfully. DB21024I This command is asynchronous and may not be effective immediately.
然后有时我们连续执行了几次备份依然不能kill掉，我们可以用另一种手段：
#找到Process ID of client application
[[email protected] bin]$ db2 get snapshot for application agentid 55|less
Application Snapshot
Application handle = 55
Application status = Connect Completed
Status change time = Not Collected
Application code page = 1208
Application country/region code = 0
DUOW correlation token = *LOCAL.db2inst1.150104134326
Application name = db2bp
Application ID = *LOCAL.db2inst1.150104134326
Sequence number = 00001
TP Monitor client user ID =
TP Monitor client workstation name =
TP Monitor client application name =
TP Monitor client accounting string =
Connection request start timestamp = 2015-01-04 21:43:26.408291
Connect request completion timestamp = 2015-01-04 21:43:28.310947
Application idle time = Not Collected
CONNECT Authorization ID = DB2INST1
Client login ID = db2inst1
Configuration NNAME of client = limt
Client database manager product ID = SQL10010
Process ID of client application = 4153 # 此处为要找到的BP进程号
Platform of client application = LINUXAMD64
Communication protocol of client = Local Client
#此进程为db2bp
[[email protected] bin]$ ps -ef|grep 4153
db2inst1 4153 1 0 21:28 pts/0 00:00:00 /home/db2inst1/sqllib/bin/db2bp 3796A502 5 A
db2inst1 4961 3796 0 21:46 pts/0 00:00:00 grep 4153
[[email protected] bin]$ kill -9 4153
#这个时候再次查看备份连接就消失了
这个办法一般也适合force C程序的嵌入式SQL程序
