		<description><![CDATA[tusc 是一个在 HP-UX 平台上用来跟踪系统调用的程序，其功能类似于 Linux 上的 strace 和 Solaris  上的 truss。最近两天应大洋彼岸的同事要求，要提供某个重要的 Oracle 数据库进程的 tusc 输出，可是在我用的 HP-UX 的测试机上并没有默认安装它。最后 Google 出来了 tusc 的安装方法，记录于此。
答案来自于 HP IT Resource Center 的论坛上的一篇帖子。其实安装过程很简单：
1 在这里下载版本合适的 tusc 安装文件压缩包；
2 以 root 身份使用 swinstall 命令进行安装。
默认的安装路径是在 /usr/local/bin/tusc，之后就可以开始使用了。最后这里顺便给出一个例子：
tusc -o tusc.out -aEfhpRunv -T &#8220;&#8221; -p pid

		<description><![CDATA[由于工作任务的重新分配，这周开始我接手了RAC在HP-UX IA64平台上的release testing，可能在未来一段时间内都要在这个陌生的平台上进行工作。希望能尽快掌握这个平台的一些知识吧，幸好同事yingwei的文档记录非常详细，让我少走了不少弯路。
今天先来说说2个内核参数shmmni和shmseg的设置。问题出现在用OUI进行11106的database software only安装的时候，安装前的内核参数检查在对这2个参数进行检查时报告failed，于是又手工运行CLUVFY工具（Clusterware已经安装完成）进行检查：
$CRS_HOME/bin/cluvfy stage -pre dbinst -n all -verbose
对于这2个参数的检查结果如下：

<p>看来我所用的系统里面这2个内核参数的值都没有达到要求，需要进行修改。修改的方法竟然可以在DB2的在线文档中找到中文版：</p>
<blockquote>
<h3 id="t0006477">修改内核参数（HP-UX）</h3>
<div><a id="idx102" name="idx102"></a><a id="idx103" name="idx103"></a><a id="idx104" name="idx104"></a></div>
<p>在安装 DB2 HP-UX 版产品之前，可能需要更新系统的内核配置参数。更新内核配置参数之后，必须重新启动计算机。</p>
<div><span class="pblktitle">先决条件 </span>必须具有 <tt class="xph">root 用户</tt>权限才能修改内核参数。</div>
<div><span class="pblktitle">过程 </span>要修改内核参数：</p>
<ol type="1">
<li>输入 <span class="bold">sam </span> 命令来启动“系统管理管理器”（SAM）程序。</li>
<li>双击 <span class="bold">内核配置 </span>图标。</li>
<li>双击 <span class="bold">可配置的参数 </span>图标。</li>
<li>双击要更改的参数，并在 <span class="bold">公式／值 </span>字段中输入新值。</li>
<li>单击 <span class="bold">确定 </span>。</li>
<li>对所有要更改的内核配置参数重复这些步骤。</li>
<li>当完成对所有内核配置参数的设置时，请从操作菜单栏中选择 <span class="bold">操作 </span> &#8211;&gt; <span class="bold">处理新内核 </span>。</li>
</ol>
</div>
<p class="indatacontent">更改内核配置参数的值之后，HP-UX 操作系统将自动重新启动。</p>

			<content:encoded><![CDATA[<p>When you place a physical disk under Volume Manager control, a Volume Manager disk (or VM disk) is assigned to the physical disk.</p>
<p>A VM disk typically includes a public region (allocated storage) and a private region where Volume Manager internal configuration information is stored.</p>
<p>A disk group is a collection of VM disks that share a common configuration.</p>
<p>A disk group configuration is a set of records with detailed information about related Volume Manager objects, their attributes, and their connections.</p>
<p>Volumes are created within a disk group. A given volume must be configured from disks in the same disk group.</p>
<p>A subdisk is a set of contiguous disk blocks. A block is a unit of space on the disk. Volume Manager allocates disk space using subdisks.</p>
<p>The Volume Manager uses subdisks to build virtual objects called plexes. A plex consists of one or more subdisks located on one or more physical disks.</p>
<p>A volume is a virtual disk device that appears to applications, databases, and file systems as a physical disk, but does not have the physical limitations of a physical disk device.</p>
<p>A volume consists of one or more plexes, each holding a copy of the selected data in the volume. Due to its virtual nature, a volume is not restricted to a particular disk or a specific area of disk.</p>
<p>A volume can consist of up to 32 plexes, each of which consists of one or more subdisks.</p>
