  mysql高可用架构之mha 文档

该软件由两部分组成:MHA Manager(管理节点)和MHA Node(数据节点)。MHA Manager可以单独部署在一台独立的机器上管理多个master-slave集群,也可以部署在一台slave节点上。MHA Node运行在每台MySQL服务器上,MHA Manager会定时探测集群中的master节点,当master出现故障时,它可以自动将最新数据的slave提升为新的master,然后将所有其他的slave重新指向新的master。整个故障转移过程对应用程序完全透明。

mysql mha安装 文档

mha是自动化完成mysql replcation结构的故障转移。可以快速完成将从服务器晋级为主服务器(通常10-30s),不会造成同步中数据一致,而且不需要购买更多的服务器,也不会有性能损耗,没有复杂的部署(非常容易安装),最为厉害的也不用更改现有的布署环境。

ORACLE CLUSTER FILE SYSTEM 文档

This document is for folks who are interested in understanding OCFS internals. It wasn’t planned to actually write a design document, but I did this out of my interest to help folks who are interested in understanding how OCFS works. I have put this information in writing while I was walking through the code (ocfs version 1.0.9-9) and understanding how OCFS is implemented.

ocfs2 -fashen 文档

This talk will review the various components of the OCFS2 stack, with a focus on the file system and its clustering aspects. OCFS2 extends many local file system features to the cluster, some of the more interesting of which are posix unlink semantics, data consistency,shared readable mmap, etc.

mysql性能优化 文档

大多数的MySQL服务器都开启了查询缓存。这是提高性最有效的方法之一,而且这是被MySQL的数据库引擎处理的。当有很多相同的查询被执行了多次的时候,这些查询结果会被放到一个缓存中,这样,后续的相同的查询就不用操作表而直接访问缓存结果了。

oracle automatic storage management.2007 文档

The idea for Automatic Storage Management (ASM) first occurred to me in early 1996. A computer manufacturer that I was visiting gave me a presentation on a filesystem for video serving. The manufacturer’s plan was to put one or two full-length movies on a single physical disk. The company would make a new copy of the movie for every 10 viewers. The next day I was thinking about this and realized that the plan could not work. I came to the conclusion that the only workable solution was to stripe the movies across a large number of disks with a very large stripe. I was not the first person to figure this out. That was the basic strategy behind the Oracle video server, but I did not know that then.

oracle core_ essential internals for dba - lewis_jonathan 文档

Oracle Core很可能是未来十年关于Oracle内部原理最好的书。  作者在第一章从一个简化的原理图出发,做了一个轻松的开始,后面7个章节的内容密度却让人惊叹,对我自己而言,读到第三遍之后,才把前后各个知识点联系起来。除了知识本身,Jonathan所展示的他研究Oracle的思路和方法或许更有借鉴意义。
