db2 SQL6036N解决办法

问题背景：

数据库在进行大量的运算和数据处理的过程中，IO、CPU等资源消耗非常高的时候，强制停止数据库。db2stop force

结果数据库命令迟迟没有响应。这个时候对数据库进行其他操作均无响应，执行启动命令，返回SQL6036N。此时说明数据库已经hung了。

或 调试存储过程，导致数据库hung，想要通过控制中心重启下db2，结果长时间没有任何反应，再想重新连接时报错，如下

SQL6036N  START 或 STOP DATABASE MANAGER 命令已在处理之中。

db2stop 命令同样会报相同的错

解决办法：

删除/home/username/sqllib/ctrl/db2strst.lck文件，默认这个文件是空的。

执行db2_kill，会提示：Application ipclean:Removing DB2 engine and client IPC resources for db2name.

重新启动db2start，查看数据库的活动状态：db2 list active databases 会显示当前活动库，这时候说明数据库已经恢复正常了。

SQL6036N maybe seen when issuing db2stop or db2start, or the command may hang.
