DB2数据库表的解锁

数据库
下面为您介绍DB2数据库中,如何才能将数据库表进行解锁,供您参考,希望对您有所帮助。

#p##p#下面为您介绍DB2数据库中,如何才能将数据库表进行解锁,供您参考,希望对您有所帮助。

在DB2的命令行中输入:

update monitor switches using lock on table on

然后打开另一个DB2命令窗口执行我的那个被吊死的Update语句。

然后在第一个DB2命令窗口执行:

get snapshot for locks on Database_Name(你的数据库的名字)> locks.TXT

然后,可以看到第一个DB2的窗口有一个信息输出,把这些信息输出到TXT中,大致如下:

应用程序句柄                    = 36

其中应用程序句柄43和557的状态都是死锁了,猜测是这2个应用争用DB2的表,造成死锁,根据日志提示,在DB2的命令窗口输入:

force application (43)

force application (557)

提示这个操作是异步的,我执行list applicaions,结果进程中还有那2个进程,那2个进程可能是在执行比较大的操作,需要耐心等待,如何还不行,则使用下面的命令来强制所有的应用都停止,然后重启DB2:

force application all

terminate

db2stop force

db2start

如果DB2在Window上,则可以使用“控制中心”->实例->右键“应用程序”,可以看到当前的锁定情况,并且可以强行关闭某个进程,也可以显示“锁定链”。
