MySQL:MySQLTransactionRollbackException - Lock wait timeout exceeded; try restarting transaction

Lockwaittimeoutexceeded解决优化方案一,定位问题可以通过以下几种命令去定位二,解决方案紧急措施1.紧急措施:终止(KILL)相关的线程,释放任何被该线程持有的锁2.次之紧急措施:调整Innodb锁等待时间,延缓了问题的出现非紧急措施“Lockwaittimeoutexceeded;tryrestartingtransaction”一般出现这样的错误时,往往是因为一些事务在等待获取某个锁,但由于这个锁被其他长时间未完成的事务持有,所以导致等待超时。一,定位问题可以通过以下几种命令去定位SHOWFULLPROCESSLIST;显示当前MySQL中的所有进程信息,包括每个进程的
