今天不知道按了什么,发现Eclipse右下角一直提示computing additional info,打开progress,里面同时有好几条一样的信息,但是一直也执行不完,上网查找方案,发现原来是用了content assist (也就是,按下alt + / ,会出来代码提示)的功能造成的.eclipse会去查找java的源代码,首先在本地找,然后到internet上找.本地默认是没有java的源代码.computing additional info表示在搜索internet上的java的源…

一点一点学习jobs的各个方面比较长,比较烦,但是应该看完后会对jobs比较好的应用 一.学习准备 开始dbms_job学习前,先认识一个参数job_queue_processes a.job_queue_processes参数决定了job作业能够使用的总进程数.b.当该参数为0值,任何job都不会被执行,建议合理设置该值且至少大于1.c.对于job运行时间也应该尽量合理的设置间隔以及启动时间.d.如果同一时间内运行的Job数很多,过小的参数值导致job不得不进行等待.而过大的参数值则消耗更多的…

今天会计反映关不了工单.我们公司关工单的程序是自己开发的,可以整批关.报如下错误.我试着用Standad程序关,可以.看来应该是我们开发的程序有问题.后来发现,是抛到WIP_DJ_CLOSE_TEMP的ACTUAL_CLOSE_DATE的数据有问题,只要没有时分秒的,就会报错.检查自己开发的程序,发现代码中有个判断,时间是每月最后一天,时间就抛TRUNC (SYSDATE).去掉这个判断,全部抛SYSDATE后,程序恢复正常.+----------------------------------…

Iveely.Computing是参考Storm的分布式实时计算系统的部分原理,用纯Java实现的轻量级.迷你型,适合于搜索引擎的实时计算系统, Iveely 搜索引擎是一款基于Iveely.Computing的搜索引擎,因此部署Iveely.Computing是使用Iveely搜索的关键,通过验证,Iveely搜索稳定在Iveely.Computing上运行了一个月. 一个完整的部署文件包含以下内容: Zookeeper 是必要的协调服务. Master 是Iveey.Computing的任务…

当我们写完一个比较复杂的Topology之后,倘若直接提交到服务器上运行,难免会有很多问题,如何进行本地的调试Topology,是我们非常关心的问题.我们依然以WordCount作为代码示例. 首先,必须调整main函数. 当main函数中,设定薇本地模式后,即可直接如调试Java应用程序一样,调试相应的代码,由于本地调试中,Computing会运行一个Local Cluster,因此在调试的时候,一样要添加对zookeeper的引用,如下: 但是,在最终打包的到服务器上运行的时候,无须将zoo…
