做了几年的DBA，接触了不同的平台环境，积累了一些经验，终于发现到了一个瓶颈，需要把这几年的日记整理一下，思考一下，毕竟还是想更上一层楼的。

呵呵。 所以决定开始蚂蚁搬家，把纸面上的东西挪到这里来，希望能对自己有所帮助，万一哪位不小心看到了且恰好有用，是俺的荣幸；要是觉得不好，或是错了，欢迎指正批评。

After several years as being an Oracle DBA and get familiar with some platform, I am thinking that I might at the point to step forward; I need to try to manage all those files that represent my past work and really think about my future.

So I decided to move all my past diary from paper into this space, I wish this will help myself, and if there is a tiny little chance that anyone pass by and get help, I'll be honored; otherwise, please drop a word to correct me.
