Season in the Sun: April 2009

Season in the Sun. Monday, April 20, 2009. A whole new world. Oracle buys Sun Microsystem. What will it look like when Oracle MySQL and Berkeley DB come together? Which one is better Oracle Internet Directory(OID) or Sun Directory Server? JAVA maybe is the only one that is needed by everyone. What will the fate of Solaris be， another Linux or FreeBSD？ Network is still computer， but Sun is no longer that Sun was. Links to this post. Friday, April 3, 2009. 65306;number of parameters. Read MAJOR MINOR PATCH.

Season in the Sun. Tuesday, June 12, 2007. One of the most silly things Sun have done is to manage disk array using Java web console. When you want to set the disk array such as STK 6140 or 6540, you have to install Java, Tomcat and Common array manager on your Windows laptop. When all components above installed succsessfully, remember to modify your firewall settings and registry, or you'll get "Authentication failed" message when logining to the Java web console. Using regedit on your XP system and set.

Season in the Sun: Google's BigTable
http://all-unix.blogspot.com/2007/12/googles-bigtable.html
Season in the Sun. Monday, December 3, 2007. 官方的 Google Reader blog 中有对BigTable 的解释。这是Google 内部开发的一个用来处理大数据量的系统。这种系统适合处理半结构化的数据比如 RSS 数据源。 以下发言是 Andrew Hitchcock 在 2005 年10月18号基于： Google 的工程师 Jeff Dean 在华盛顿大学的一次谈话 (Creative Commons License). Tablets在系统中的存储方式是不可修改的 immutable 的SSTables，一台机器一个日志文件。当系统的内存满后，系统会压缩一些Tablets。由于Jeff在论述这点的时候说的很快，所以我没有时间把听到的都记录下来，因此下面是一个大概的说明：. 客户端有一个指向METAO的Tablets的指针。如果METAO的Tablets被频繁使用，那个这台机器就会放弃其他的tablets专门支 持METAO这个Tablets。METAO tablets 保持着所有的META1的table...也许有列：”...

Season in the Sun. Tuesday, February 13, 2007. Shellcode on Solaris 10 (x86) Using sysenter. Lcall $0x07, $0x0是很久以前就在使用的系统调用方式。Intel提供了sysenter快速系统调用指令，如果在shellcode的编写中使用该指令，可以缩短shellcode的长度，让我们试一下。代码如下：. Asm ("jmp . 0x24 n t"); /* 跳转到call指令 ＊/. Asm ("popl %esi n t"); /* 字符串的地址放入%esi */. Asm ("movl %esi, -0x8(%ebp) n t"); /* 将字符串的地址保存在栈内存中 */. Asm ("xorl %eax, %eax n t");. Asm ("movl %eax, -0x4(%ebp) n t");. Asm ("subl $0x4, %esp n t");. Asm ("push %eax n t"); /* NULL字符入栈 */. Asm ("movl %esi, %edx n t");.

Season in the Sun. Wednesday, February 27, 2008. Lustre File System at a glance. Lustre is a very fast, multi-network, scalable cluster filesystem for Linux. It uses Object-Based Storage Devices (OBDs), to manage entire file objects (that is, inodes) instead of blocks. Several specific components/sub-systems of Lustre include Meta Data Servers (MDSs), Object Storage Targets (OSTs), and Lustre clients. Lustre installation/configuration requires the following:. Lustre modules compiled for the above kernel.

Season in the Sun. Friday, April 27, 2007. A Comparison of Solaris, Linux, and FreeBSD Kernels. I spend most of my time teaching classes on Solaris internals, device drivers, and kernel crash dump analysis and debugging. When explaining to classes how various subsystems are implemented in Solaris, students often ask, "How does it work in Linux? Or, "In FreeBSD, it works like this, how about Solaris?
