背景 最近在使用EFCore去连接阿里云上面的数据库进行开发的时候,当自己在Debug模式下总是提示下面的报错信息,然后找了好久都没有解决,报错信息如下: an exception has been raised that is likely due to a transient failure. Consider enabling transient error resiliency by adding 'EnableRetryOnFailure()' to the 'UseSqlServer
Sometimes,you need to manipulate the default values of certain properties of a socket library, for example, the socket timeout. 设定并获取默认的套接字超时时间. 1.代码 import socket def test_socket_timeout(): s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) print
mysql 事务锁超时时间 innodb_lock_wait_timeout: # 查询全局等待事务锁超时时间 SHOW GLOBAL VARIABLES LIKE 'innodb_lock_wait_timeout'; # 设置全局等待事务锁超时时间 SET GLOBAL innodb_lock_wait_timeout=; # 查询当前会话等待事务锁超时时间 SHOW VARIABLES LIKE 'innodb_lock_wait_timeout';
Mysql数据库采用InnoDB模式,默认参数:innodb_lock_wait_timeout设置锁等待的时间是50s,一旦数据库锁超过这个时间就会报错. mysql> SHOW GLOBAL VARIABLES LIKE 'innodb_lock_wait_timeout';+--------------------------+-------+| Variable_name | Value |+--------------------------+-------+| innodb_lock
