有三个系统变量tcp_keepalives_idle,tcp_keepalives_interval ,tcp_keepalives_count 来设置postgresql如何处理死连接。 在postgresql, 这三个参数都设为0将使用操作系统的默认值,在linux下,tcp_keepalives_idle一般是2个小时,也就是2个小时后,服务器才可以自动关掉死连接。 在实际应运中,
tcp_keepalives_idle = 7200 tcp_keepalives_interval = 130 tcp_keepalives_count = 3 shared_buffers = 256MB work_mem = 16MB maintenance_work_mem = 128MB wal_level = logical full_page_writes = on max_wal_size = 1GB min_wal_size = 80MB wal_keep_segments = 32 logging_collector = o...

我们已经尝试过定义tcp_keepalives_idle=300、tcp_keepalives_interval=30和tcp_keepalives_count=3,但空闲会话的数量仍然是数百个。当我们关闭空闲会话或重新启动数据库时,空闲会话重新连接,并保持空闲。 浏览0提问于2020-09-30得票数 0 2回答 锁定SELECT,以便另一个进程不会获得旧数据 、、、 在我看来,...
