❶ 程序员删库跑路是一种什么行为

因为对公司不满。这个程序员辞职了,没有得到应有的待遇。发生这种事只是一时赌气。您好!这个通常一天备份一次。即使它被删除,也可以通过归档日志来恢复。事实上,你应该控制你的权威。如果能给他们访问权限的用户没有删除数据库的权限岂不是很好?祝您好运。听说IT运维人员学到的第一课就是“从删数据库到跑马路”。

只是有点慢。比如在此次事件中被删除的魏梦,已经宣布已经完全取回数据,所以涉及的数据和备份都达到了一天几个级别。所以微信数据库很有可能不是一个运维人员掌握的,而是分成几个甚至上百个部分,分别由不同运维控制。每个操作和维护都有不同的权限,不能相互访问。甚至每一条数据都存储在不同的地方。这样,即使运维数据库删除中有一个跑了,也可能是数据库的一小部分影响了微信,不会影响整体。比如删除某个用户数据库,可能只会导致几十万或者几百万的微信用户正常登录,但其他大部分用户可能根本感受不到任何影响。此外,微信的聊天数据并不存储在服务器中,而是存储在用户的手机中。

❷ 求最新的笑话数据库,数量越多越好,最好是MySQL导出的,可以加分哦

请采纳我的问题1、一个女生前一天晚上得到男朋友的订婚戒指,但竟没有一个同学注意到,令她忿忿不平。到下午大家坐着谈天的时候,她突然站起来大声说:“哎呀,这里真热呀,我看我还是把戒指脱下来吧。”2、女主人把女佣叫到面前问她:“你是否怀孕了?”“是啊!”女佣回道。“亏你还说得出口,你还没有结婚,难道不觉得害羞吗?”女主人再次训。“我为什么要害羞,女主人你自己不也怀孕了吗?”“可是我怀的是我丈夫的!”女主人生气地反驳。“我也是啊!”女佣高兴地附和。3、一个人骑摩托车喜欢反穿衣服,就是把口子在后面扣上,可以挡风。一天他酒后驾驶, 翻了,一头栽在路旁。警察赶到:警察甲:好严重的车祸。警察乙:是啊,脑袋都撞到后面去了。警察甲:嗯,还有呼吸,我们帮他把头转回来吧。警察乙:好.....一、二使劲,转回来了。警察甲:嗯,没有呼吸了.......4、在一条七拐八拐的乡村公路上,因为时常发生车祸,所以常常有一些鬼故事发生,有一天晚上,有一个出租车司机看见路边有一个长发披肩,身着白衣的女人向他招手,因为这个司机没有见过鬼,所以大胆的停下来让她上车了,这一路上,司机虽然不信有鬼,心里也毛毛的,所以时常从后视镜看后面的女人,开着开着,突然司机发现那个女人不见了!司机吓了一大跳,赶紧踩了一个刹车!只见那个女人满脸是血,表情狰狞。司机吓的牙直打颤。突然那女人开口了:“你会不会开车啊!我低头系个鞋带你突然一刹车我把鼻子都撞破了……”5、一个病人去看病,医生检查了他,皱着眉头说:“您病得太严重了,恐怕不会活多久了。” 病人:“求您告诉我我还能活多久?” 医生:“十……” 病人着急地问:“十什么?十年??十个月???十天?????” 医生:“十,九,八,七,六,五……”6、老师:“你能说一些18世纪科学家共同特点吗?”学生:“能,他们都死了。”7、犀粪蜣和蚊子谈恋爱,蜣问蚊子是做什么工作的,蚊子说:“护士,打针的。”蜣一拍大腿:“缘分呐,我是中药局搓药丸的…”8、一非洲人住在某一宾馆。夜半,起火,不明原因。非洲人见状顾不了那么许多,光着身子就跑出去了。消防员见状惊呼:“我的妈呀!都烧的糊了吧区的了还能跑那么快!”9、一个人想出国考察,但必须得到老总批准。于是他向老总请示,老总给了他一张字条,上面写着:“Go ahead”。 那人想:“Go ahead=前进,老总是批准了。”于是他开始打点行李。 一个同事见到了他问:“你在做什啊??”他说:“我准备出国考察,老总批准了,给我写了‘Go ahead’。” 同事一见条就乐了:“咱们老总根本就没批准!!咱老总的英语水平你还不知道,他这是在说去个头!”10、牧师对买了他马和马车的农夫说:“这匹马只能听懂教会的语言,叫"感谢上帝"它就跑;叫"赞美上帝"它才停下。”农夫将信将疑,他试着喊了一声感谢上帝,那匹马立刻飞奔起来,越跑越快。一只跑到悬崖边上惊恐的农夫才想起让它停下来的口令“赞美上帝”。果然,马停下来了。死里逃生的农夫长出一口气:“感谢上帝………”我打了很久,请采纳1 the night before, a girl get boyfriend engagement ring, but no one noticed the classmate, make her antics.

❸ 纠结安装使用oracle数据库问题

(1)oracle不会查,这么多年就见过一个访问量特别大的(大概10年前,一天10G数据量左右,但是有些人的数据量和他差不多也没被查)被查了(其实就是不能用了,连上网就不能用,内部用的话没有问题),其他没见过被查的。几十兆,oracle估计懒得管。(案值太低)
(2)oracle买的不是产品是服务,买了以后享受各种售后服务,当然买的时候不这么说,而是说买CPU或者用户(具体怎么买我忘了),所以如果单独装上那么是没有售后的,千万不要打售后电话,不然被查的可能性将急剧上升。
(3)1521端口改一个吧,因为1521大家都知道是oracle服务器端口,在阿里云上连接到本地服务器,也就是说需要走公网,如果有人知道了阿里云的地址,那么1521端口就是一个攻击点,改一个端口(没什么特殊意义的端口),这样能稍微安全一点点(只有一点点)。
(4)oracle不管是什么版本的,只要是oracle是不是在官网上下载都是一样的(只要你下载的不是测试版,我见过有人用测试版装正式系统,结果出了大笑话,测试版不能搭建rac,结果又去重装的),就算是从别人那里拿过来的也一样,oracle可没有地方输入什么序列号一类的地方,所以是不是官网下载的不重要,oracle没有盗版的。
(5)就算oracle将来查起来,也是对公司不会对人,就算是你自己公司安装的,公司也没办法找你的麻烦,因为oracle是公司要装的,而且我上面也说了,oracle是没有盗版的,所以如果oracle要查,而且你的oracle还连接着公网,那么谁也拦不住,只要不是你大力推荐的oracle就行了,当然可能会受到波及,比如成为领导推卸责任的工具人一类的,那也没办法,毕竟一线干活的都是这待遇。
