7 years ago 我是通过eclipse来运行mycat-server和mycat-web, mycat-web可以使用, 但是mycat-web后台报上述错误. 解决问题方法如下: 运行mycat-server时,增加虚拟机参数 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+UseCMSCompactAtFullCollection -XX:CMSFullGCsBeforeCompaction=0 -XX:CMSInitiatingOccupancyFraction=70
Mycat-Web启动后,约10s左右就出现如下错误, 有没有碰到过的同学。 2017-08-21 18:02:21.293 ERROR jrds.Probe.JMXConcMarkSweepGC:705 - [JMX_IP_PORT/jvmpool-mycat-jmx] JMX instance not found: java.lang:type=MemoryPool,name=Par
