如何在windows Server 2008 R2下突破Rabbitmq的socket限制数

利用Rabbitmq进行各类业务系统(如SAP、OA、EHR、KMS、访客系统、AD等)的集成和接口,已有很长一段时间了,初步建立了企业服务总线(ESB)。随着新业务系统的不断接入到ESB中,在实践中也发现了一些问题并总结了一些经验,下文主要介绍如何在windows下突破Rabbitmq的socket限制数,以便为需要使用的同学分享一些实际经验,后续将陆续分享一些技术经验

1、 如何在windows下扩展sockets数量,提高吞吐量?

(1)、需要在windows系统环境变量中设置erlang的ERL_MAX_PORTS
