Linux Versions and Patches
Linux version
[1] 2.6.10
2.6 version number, 10 release number
[2] 2.6.10 and 2.6.11
They can differ significantly even in core components and in fundamental algorithms
[3] 2.6.11.12
when a new kernel release appears, it is potentially unstable and buggy. To address this problem, the kernel developers may release patched versions of any kernel, which are identified by a fourth number in the version numbering scheme
Which patch to apply which Release?
[1] Stable kernel patches apply to the base kernel version.
patch-2.6.17.10 --> linux-2.6.17 = linux-2.6.17.10
patch-2.6.17.10 -/-> linux-2.6.17.9
[2] base kernel release patches only apply to the previous base kernel version.
patch-2.6.18 --> linux-2.6.17 = linux-2.6.18
patch-2.6.18 -/-> linux-2.6.17.2
[3] incremental patches upgrade from a specific release to the next release
patch-2.6.17.10-11 --> linux-2.6.17.10 = linux-2.6.17.11
An example
How to go from the 2.6.17.9 kernel release, to the 2.6.17.11 release?
Finding the incremental patches http://www.kernel.org/pub/linux/kernel/v2.6/incr/
patch-2.6.17.9-10 --> linux-2.6.17.9 = linux-2.6.17.10
patch-2.6.17.10-11 --> linux-2.6.17.10 = linux-2.6.17.11

1. linux下启动oracle
su - oracle
sqlplus /nolog
conn /as sysdba
startup
exit
lsnrctl start
exit
2. linux下关闭oracle
su - oracle
sqlplus /nolog
conn /as sysdba
shutdown immediate
exit
lsnrctl stop
exit
可以使用lsnrctl 进去后用status查看状态，类似：
lsnrctl
status

I/O重定向详解及应用实例
1、 基本概念（这是理解后面的知识的前提，请务必理解）
a、 I/O重定向通常与 FD有关，shell的FD通常为10个，即 0～9；
b、 常用FD有3个，为0（stdin，标准输入）、1（stdout，标准输出）、2（stderr，标准错误输 ......
昨天郁闷了一天，因为不管我如何编译，总是有错误产生。
没想到今天我清理掉所有文件，重新操作了一编，居然神奇般编译成功了。挖哈哈。。。太高兴了，终于离编译可运行在IPHONE
机器上的HELLO world 不远了，太激动了。。
总结一下：我昨天安装了管方列出的所有包，还有就是不放弃，多试几次。
Here we provide a list ......
