使用Dell iDRAC服务器远程控制安装操作系统简要图解 iDARC tools   iDRAC又称为Integrated Dell Remote Access Controller,也就是集成戴尔远程控制卡,这是戴尔服务器的独有功能,iDRAC卡相当于是附加在服务器上的一计算机,可以实现一对一的服务器远程管理与监控,通过与服务器主板上的管理芯片BMC进行通信,监控与管理服务器的硬件状态信息.它拥有自己的系统和IP地址,与服务器上的OS无关.是管理员进行远程访问和管理的利器,戴尔服务器集成了i…

前些时间,我们的的一个管理系统出现了点问题,原本运行的好好的功能,业务方突然讲不行了,那个应用已经运行了好多年了,并且对应的代码最近谁也没改动过,好奇怪的问题,为了解决此问题,我们查看了日志,发现请求的参数压根没有传到后台控制器之中,奇怪了!明明前端传递了好多参数过来了呀!线上系统比较重要,又需要马上使用必须赶紧解决呀! 提交请求时的页面反应,如下所示: 于是我们想在本地模拟同样的操作,可气的是本地压根没任何问题,好头疼,对于这样的问题确实是最令人头疼的,同样的代码一边运行不了,一边屁事没有,后…

错误的意思是:已达到可容忍的服务器重连接错误的最大数目.有两个解决思路:一个将这个值设置的更大:然后是排查自己连接服务哪儿出了问题.先说在哪儿设置这个值:在拉取nacos服务的注解配置中,添加一个属性maxRetry,这个值源码中默认给的是3,可以将其设置的更大一些. @Configuration @EnableNacosConfig(globalProperties = @NacosProperties(serverAddr = "127.0.0.1:8848", namespace…

我们大体都知道ArcSDE的连接数有 48 的限制,很多人也知道这个参数可以修改,并且每种操作系统能支持的最大连接数是不同的. 如果应用报错:超出系统最大连接数 该如何处理? 两种解决办法: 第一,首先确定是否一定需要增加这个最大连接数. 在我们平常的应用中, 特别是给多用户的实施过程中. 有时会出现图形库莫名的连接不上,如果用ARCMAP或ARCCATALOG连接的时候还会提示错误信息 “Failed to connect to database. Maximum number of cone…
