Restore original maxConnections default for NIO2 as the underlying close issues have been fixed. (remm) Harmonize NIO2 isReadyForWrite with isReadyForRead code. (remm) When using a JSSE TLS connector that supported ALPN (Java 9 onwards) and a protocol was not negotiated, Tomcat failed to...
default is200. If not using Servlet 3.0 asynchronous processing, a good default is to use the same as the maxThreads setting. If using Servlet 3.0 asynchronous processing, a good default is to use the larger of maxThreads and the
可见当maxActive大于maxIdle时,活跃连接超过maxIdle后归还就会被关闭,再获取时如果没有可用连接,总连接数又小于maxActive时,又会新建连接,因此这种情况会带来连接池伸缩造成的性能开销,因此推荐配置maxActive等于maxIdle避免连接池伸缩开销。 initialSize是在连接池创建时的初始连接个数,如果启动evictor且initialSize小于minIdl...
maxConnections的设置与Tomcat的运行模式有关。 如果tomcat使用的是BIO,那么maxConnections的值应该与maxThreads一致;如果tomcat使用的是NIO,那么类似于Tomcat的默认值,maxConnections值应该远大于maxThreads。 通过前面的介绍可以知道,虽然tomcat同时可以处理的连接数目是maxConnections,但服务器中可以同时接收的连接数为maxConne...
new connections again. Note that once the limit has been reached, the operating system may still accept connections based on theacceptCountsetting. The default value is8192.For NIO/NIO2 only, setting the value to -1, will disable the maxConnections feature and connections will not be counted....
Tomcat9 利用memcached1.6.15实现no sticky模式的会话Cluster复制和高可用性。 Tomcat9 和 memcached 1.6.15安装在同一台主机(也可以安装在不同主机上,通过网络通信交互数据,考虑到实验的快捷,本次就安装在同一主机上),采用no sticky 模式实现。并编写一个 showmemcached.py 的python程序,直观观测 session 在memcached...
