最近有些失落,原因就是经常马虎,一件很小的事儿,总会出些令人哭笑不得的错误。就比如昨天晚上加班,因为db2升级,需要把集群上每个节点的数据库驱动jar包更换下,一件很简单的事情。但是因为节点很多,如果一个个jar包去更换的话我得操作八次,这样效率很低,之后我发现如果把目录下文件全部替换的话我只需要操作两次,这样效率高多了,于是我就这样做了。结果是....更换后有两个节点连接数据库时报错了,花了三个小时去排错,令人吐血的是最后发现这两个节点之前用的数据库jar包名字不叫更新后的数据库jar包名字!!!这样算起来用的时间远远大于我一个个文件去操作....
反思下,我做事之所以出错都是因为没有按部就班的一步步来,老是耍些自以为是的小聪明,然后做的事情已经与目的背离了。然后是出错,出错后提心吊胆的,于精神上也是一种折磨。
1`以后做事情要按部就班的去做,如果觉得有更好的方法时可用时一定要谨慎,自己先分析清楚是否有风险,然后咨询一下领导意见,如果可行,就用更好的方法,不然就按原来的方法一步步做。
2`戒骄戒躁,不能为了早点做完事情而省略哪怕很小的步骤。
3`事情做完后一定要验证正确性
