<blockquote><p>AIX MPIO is supported on AIX starting from AIX 5.2 TL10, AIX 5.3 TL6 and AIX 6.1 SP2 though various PTFs and fixes may be required (see interoperability matrix and AIX MPIO documentation below). It is supported with DS4000 firmware 6.60.xx.xx and higher on DS4800, DS4700, DS4200, DS4500 and DS4300. MPIO is the strategic driver for all current DS4000 platforms in AIX 6.1 and up &#8211; except for DS4400 which is RDAC only. RDAC is the default driver on all levels of AIX 5.2 and 5.3.</p>
<p>In AIX Version 6.1, the DS4K products are configured as Multipath I/O (MPIO) devices by default. A DS4K product using the FCPARRAY (RDAC) driver may be migrated to the MPIO driver by using the instructions found in the documents below, or all DS4K devices may be migrated by uninstalling the devices.fcp.disk.array.rte package and then running the cfgmgr command or rebooting.</p></blockquote>

		<description><![CDATA[因为公司客户的关系，需要了解学习IBM产品基础知识：aix、ds storage、informix、websphere、tsm、db2。拜读过&#60;&#60;走入IBM小型机世界&#62;&#62;的作者 Orian写的一点感想及aix如何快速入门到精通的文章，结合自己的一点感受写下这篇博文，仅以此鼓励自己。 一、AIX系统主要管理事件 Devices management 设备管理 （安装/删除，配置等） Logic volume management 存储管理 （主要是围绕逻辑卷的创建，删除，配置等） File system management  文件系统管理（文件系统的安装/卸载，删除，备份与恢复，NFS等） Memory management （主要是关于VMM，paging space的事） CPC processor Dispatcher management （进程，作业，SRC） TCP/IP network management  (系统的网络管理，各种稀奇古怪的interface有N多) User management （用户管理） DLPAR management（动态逻辑分区管理，这得要玩转HMC啊） Cluster management（HACMP,HPC） 二、入门导向：二个基本点，一个中心 1.以理论为基础 我党再三强调要理论联系实际，可见基础知识是非常重要的。windows、unix、linux计算机系统其实都差不多。就像我们人一样，男地、女地，大人、小孩，除了外表和一些功能的强弱不同外，内部结构基本上没二样，重要的一点是：心中要有一个大概的系统结构图，它们不是孤立，内部都存在着一定的联系。 2.理论联系实际 想要玩转unix的话，那么命令行的操作是一定要熟悉的（虽然unix也有CDE，），命令多，命令的参数更多，一个命令你不敲上几十上百遍是很熟悉的。TNND，更要命的是么些参数有互斥性和组合性，千万不要死记硬背，要多练习和观察。 3.思考 记得国学大师季老的一句话： 路不空行，行必所思，思必所得。 任何时候任何事，思考都是最重要的。学得再多，事后不总结、不思考，到头来那点东西还是别人的，只不过就是在你身体里过了一遍没被消化掉更别说吸收了。 三、想精通，学编程 我正处在那门槛上，前辈们都说：不去编程是没办法精通的，你的程序编到那，你那一部分就精通了，想精通就照做吧。 四、备注： 1.遇到问题先搜索官方文档，再google、baidu啥的，无果再请教，过程很重要。不要一张口就问，真是问一遍不当回事，自己搞清楚了才算会。 2.学习资料的事 现象一： 大家还记得上中学的时候，一到周末放假，恨不得很把一桌子的书都带回家，满以为二天的时间在家能好好学习，结果是带回家了瞄都没瞄一眼然后又带回学校，到最后袋子都提坏了几个，人也瘦了几斤，想减肥，就这么简单。 现象二： 现在网上资源太多，要做到有的放矢，要有选择。就像我以前一样，不停的在网上下载资料，这样日复一日，哪怕有海量的硬盘也有放满的一天啊，最后苦于没有空间了，就删资料，结果删除的都还是没有解过压的。 [...]<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">

			<content:encoded><![CDATA[<p>因为公司客户的关系，需要了解学习IBM产品基础知识：aix、ds storage、informix、websphere、tsm、db2。拜读过&lt;&lt;<span style="color: #ff0000;"><a href="http://www.china-pub.com/41496" target="_blank">走入IBM小型机世界</a></span>&gt;&gt;的作者 Orian写的<a href="http://www.itpub.net/viewthread.php?tid=572014&amp;extra=&amp;highlight=%D2%BB%B5%E3%B8%D0%CF%EB%BC%B0aix%C8%E7%BA%CE%BF%EC%CB%D9%C8%EB%C3%C5%B5%BD%BE%AB%CD%A8&amp;page=1" target="_blank">一点感想及aix如何快速入门到精通</a>的文章，结合自己的一点感受写下这篇博文，仅以此鼓励自己。</p>
<p>一、AIX系统主要管理事件</p>
<p>Devices management 设备管理 （安装/删除，配置等）</p>
<p>Logic volume management 存储管理 （主要是围绕逻辑卷的创建，删除，配置等）</p>
<p>File system management  文件系统管理（文件系统的安装/卸载，删除，备份与恢复，NFS等）</p>
<p>Memory management （主要是关于VMM，paging space的事）</p>
<p>CPC processor Dispatcher management （进程，作业，SRC）</p>
<p>TCP/IP network management  (系统的网络管理，各种稀奇古怪的interface有N多)</p>
<p>User management （用户管理）</p>
<p>DLPAR management（动态逻辑分区管理，这得要玩转HMC啊）</p>
<p>Cluster management（HACMP,HPC）</p>
<p>二、入门导向：二个基本点，一个中心</p>
<p>1.以理论为基础</p>
<p>我党再三强调要理论联系实际，可见基础知识是非常重要的。windows、unix、linux计算机系统其实都差不多。就像我们人一样，男地、女地，大人、小孩，除了外表和一些功能的强弱不同外，内部结构基本上没二样，重要的一点是：心中要有一个大概的系统结构图，它们不是孤立，内部都存在着一定的联系。</p>
<p>2.理论联系实际</p>
<p>想要玩转unix的话，那么命令行的操作是一定要熟悉的（虽然unix也有CDE，），命令多，命令的参数更多，一个命令你不敲上几十上百遍是很熟悉的。TNND，更要命的是么些参数有互斥性和组合性，千万不要死记硬背，要多练习和观察。</p>
<p>3.思考</p>
<p>记得国学大师季老的一句话：</p>
<blockquote><p>路不空行，行必所思，思必所得。</p></blockquote>
<p>任何时候任何事，思考都是最重要的。学得再多，事后不总结、不思考，到头来那点东西还是别人的，只不过就是在你身体里过了一遍没被消化掉更别说吸收了。</p>
<p>三、想精通，学编程</p>
<p>我正处在那门槛上，前辈们都说：不去编程是没办法精通的，你的程序编到那，你那一部分就精通了，想精通就照做吧。</p>
<p>四、备注：</p>
<p>1.遇到问题先搜索官方文档，再google、baidu啥的，无果再请教，过程很重要。不要一张口就问，真是问一遍不当回事，自己搞清楚了才算会。</p>
<p>2.学习资料的事</p>
<p>现象一：</p>
<p>大家还记得上中学的时候，一到周末放假，恨不得很把一桌子的书都带回家，满以为二天的时间在家能好好学习，结果是带回家了瞄都没瞄一眼然后又带回学校，到最后袋子都提坏了几个，人也瘦了几斤，想减肥，就这么简单。</p>
<p>现象二：</p>
<p>现在网上资源太多，要做到有的放矢，要有选择。就像我以前一样，不停的在网上下载资料，这样日复一日，哪怕有海量的硬盘也有放满的一天啊，最后苦于没有空间了，就删资料，结果删除的都还是没有解过压的。</p>
<p>我得到的教训，资料不在多，在于精，搞懂一个就是一个，一口气吃不成一个胖子，需要什么资料就找什么资料，及时消化，IBM机器附带的Document CD就够看的了。</p>
<p>附<span style="color: #ff0000;">IBM常用链接</span> <a href="http://www.ochef.net/wp-content/download/ibm_usually_links.xls" target="_blank">下载</a></p>
<p>最后，请大家谨记：不知者无畏，千万不要在生产系统上进行你的libs。</p>

		<description><![CDATA[一直对Solaris与OpenSolaris的区别不是很了解，今天终于通过伟大的GOOGLE彻底搞明白了。 OpenSolaris是Sun的一个开源项目，代码更新很快，很多系统的新特性会优先在这个版本里面体现，比如DTrace和ZFS 等等，当技术成熟稳定之后会用到Solaris的后续发行版本里面。Solaris是Sun自己维护的一个版本,因为用了很多第三方的代码，有一些版权上面的关系，所以这个版本与OpenSolaris不太一样，据 sun自己宣传，Solaris中Sun拥有的代码已经全部开源到OpenSolaris上了，现在可以在sun的网站上免费下载DVD的镜像，而且SUN还提供了对Solaris的商业支持，但OpenSolaris没有任何支持。 OpenSolaris社区发布了一些基于OpenSolaris的操作系统，它们包括： Solaris Express Community Edition － 代号为Nevada，是SUN为OpenSolaris开发者发布的二进制格式的操作系统，该系统包括由最新的OpenSolaris源代码和尚未公开的技术编译而成，尚未经过测试，没有任何技术支持。该系统每两个礼拜的礼拜五更新。 Solaris Express Developer Edition － 该系统是经过测试的开发版本系统，供免费免费使用，可以在这里获得技术支持，该版本每三到四个月更新一次。 BeleniX － 基于OpenSolaris源码的LiveCD。 marTux － 基于SPARC处理器的OpenSolaris发布。 NexentaOS － 基于GNU的OpenSolaris，该系统集成了OpenSolaris内核，和开源软件（OSS）应用程序。 Schillix － 为x86，x64和EM64T发布的OpenSolaris LiveCD。 -The End-<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">

		<description><![CDATA[Solaris下的磁盘一般有3种命名方式： 逻辑设备名 物理设备名 实名 逻辑设备名是来源于物理设备名的一个连接，连接于/devices目录。所有的逻辑设备名都在目录/dev下。逻辑设备名的命名方式就是采用c#t#d#s#，会根据卷管理软件的要求进行更改的。比如:vertias volume manager下为 C：一般 controller number T：代表target number D: 一般代表disk number S: 一般代表slice number 所有在/dev下的设备又分为/dev/dsk和/dev/rdsk两中块设备和字符设备。 物理设备名 物理设备名是系统中唯一用来标识本地物理设备的。设备名在/devices下。物理设备名是由一系列的接点名组成的。用/来进行路径的区分。光纤盘与其他的不太一样是有WWN（world wide name）号来表示。 实名是有kernel为每个设备分配的一个缩写名。 Sdn：代表SCSI硬盘。 Dadn：代表ide硬盘 Ssdn：代表光纤盘 Hp下的磁盘命名方式： cciss是惠普的smart array控制器的设备名，c0指channl 0，第一个SCSI通道，d0指逻辑盘1，d1指逻辑盘2…，p1指第一个分区，p2是第二个分区…。在这种情况下，我们可以看到很多HP的服务器在通过该设备连接硬盘的时候，经常看到的设备是/dev/cciss/c0d0p1，/dev/cciss/c0d0p2，/dev/cciss/c0d0p3等。<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">

			<content:encoded><![CDATA[<p>通过自己做的实验在安装之前我觉得有必要介绍一下solaris分区：<br />
/<br />
swap  (=/tmp <a href="http://os.cnfan.net/Solaris/2027.html" target="_blank">参考Solaris 下Swap分区介绍</a>)<br />
/export/home<br />
/u01<br />
1.记录一下10R2在Solaris10上的安装步骤：<br />
系统需求检查：</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;"># /usr/sbin/prtconf | grep &quot;Memory size&quot;
Memory size: 16384 Megabytes
# /usr/sbin/swap -s
total: 56936k bytes allocated + 4840k reserved = 61776k used, 32556464k available
# df -h /tmp
Filesystem size used avail capacity Mounted on
swap 31G 0K 31G 0% /tmp
# df -h /u01
Filesystem size used avail capacity Mounted on
/dev/dsk/c1t1d0s0 134G 65M 133G 1% /ora10g</pre></div></div>

<p>内存最小要求是1G。<br />
swap的最小空间与内存大小有关，内存1G，则swap为内存的2倍，内存小于2G，则swap为内存的1.5倍，内存小于8G，swap和内存相等，内存大于8G，则swap为内存的0.75倍。<br />
/tmp目录需要至少400M以上的空间。<br />
安装目录至少需要2G以上的空间来安装软件。<br />
<span id="more-98"></span><br />
2.检查系统和系统包、字体包的安装情况：</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;"># /bin/isainfo -kv
64-bit sparcv9 kernel modules
# uname -r
5.10</pre></div></div>

<p>根据oracle的官方安装文档，要先安装package：SUNWi1cs，SUNWi15cs。在solaris的安装光盘上找到安装包之后，然后复制到/var/spool/pkg ，用命令：<br />
#pkgadd -d /var/spool/pkg SUNWi15cs<br />
出现以下错误：<br />
pkgadd: ERROR: no packages were found in<br />
直接使用pkgadd指令後，找到要裝的SUNWi1cs,SUNWi15cs直接安裝即可。</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;"># pkginfo -i SUNWarc SUNWbtool SUNWhea SUNWlibm SUNWlibms SUNWsprot
SUNWtoo SUNWi1of SUNWxwfnt SUNWi1cs SUNWi15cs SUNWsprox</pre></div></div>

<p>3.满足安装Oracle的最小要求后，就可以创建使用root用户来设置系统参数并创建Oracle用户了。<br />
在/etc/system文件后面添加下面内容：</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;">set semsys:seminfo_semmni=100
set semsys:seminfo_semmsl=256
set semsys:seminfo_semmns=1024
set semsys:seminfo_shmmax=1024000000
set semsys:seminfo_shmmni=100
set semsys:seminfo_shmmni=100
set semsys:seminfo_shmseg=10
set semsys:seminfo_shmmin=1
set noexec_user_stack=1</pre></div></div>

<p>这是对系统内存参数的调整，修改完毕后重新操作系统。</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;">-bash-3.00# more /etc/hosts
# Internet host table
::1     localhost
127.0.0.1       localhost      localhost.localdomain
192.168.0.34    sunDB          sunDB.net
# mkdir /export/home/oracle
# groupadd oinstall
# groupadd dba
# useradd -g oinstall -G dba -d /export/home/oracle -m -s /usr/bin/bash oracle
# passwd oracle
New Password:
Re-enter new Password:
passwd: password successfully changed for oracle
# chown -R oracle:oinstall /export/home/oracle
# chown –R oracle:oinstall /u01
# chmod –R 775 oracle:oinstall /export/home/oracle
#chmod –R 775 /u01
# id nobody
uid=60001(nobody) gid=60001(nobody)</pre></div></div>

<p>4.创建完用户、组，并对相应的目录进行授权后，root用户的工作结束，切换到oracle用户。注意，如果nobody用户不存在，可以通过useradd增加用户。</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;"># su - oracle
$ vi .profile</pre></div></div>

<p>编辑.prifle文件，添加下列内容：</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;">/usr/bin/stty erase ^H
umask 022
ORACLE_HOSTNAME=sunDB.net
export ORACLE_HOSTNAME
ORACLE_SID=sol10g
export ORACLE_SID
ORACLE_BASE=/u01/oracle
export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0
export ORACLE_HOME
ORACLE_TERM=xterm
export ORACLE_TERM
PATH=$PATH:$ORACLE_HOME/bin:/usr/bin:/usr/ccs/bin:/etc:/usr/openwin/bin
export PATH
NLS_LANG=&quot;SIMPLIFIED CHINESE_CHINA.ZHS16GBK&quot;
export NLS_LANG
DISPLAY=192.168.0.34:0.0
export DISPLAY</pre></div></div>

<p>由于使用XManager，因此设置DISPLAY为IP:0.0。然后建立所需安装路径：</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;">$ mkdir -p /u01/oracle/product/10.2.0
$chown -R  oracle:oinstall /u01/oracle
$chmod -R 775 /u01/oracle
$chown -R oracle:oinstall /u01/oracle/product/10.2.0
$chmod -R 775 /u01/oracle/product/10.2.0</pre></div></div>

<p>使用XManager用root登陆，执行</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;"># xhost 192.168.0.34
192.168.0.34 being added to access control list
# su - oracle</pre></div></div>

<p>进入disk1目录，执行./runInstaller，进入Oracle的安装图形界面提示输入相应的信息一路NEXT就可以了。<br />
当软件安装结束后，会提示以root执行$ORACLE_BASE/oraInventory/orainstRoot.sh和$ORACLE_HOME/root.sh脚本，执行后，点击ok，Oracle软件部分就安装完成了。<br />
dbca在建库时出现ora-27102 out of memory的错误的解决办法：<br />
更改一下建库条件则可，SGA不要选“按作用内存的比例”分配<br />
sga大小为160m<br />
当sql&gt;startup时出现:<br />
Re: Solaris 10, Oracle 10g and ORA-27102 out of memory<br />
vi $ORACLE_HOME/dbs/init.ora.*<br />
把sga的值改为270   即可</p>
<p>TNSNAME和LISTENER配置步骤很简单，就不描述了。</p>
