<p>缺省情况下不会打开 DB2 监控，而是必须在连接或实例级别上进行设置。有一系列<i>监视器开关</i>来决定是否监控某种数据元素。还预留了一个内存堆，用于包含为监控而存储的信息。</p>
<p>
						
<b>方法 1：在实例级别上设置监视器开关</b>
					
</p>
<p>在实例级别上设置监视器开关会影响连接到该实例中任何数据库的所有用户。</p>
<p>
下面是监视器开关
					</p>
<ul>
<li>DFT_MON_STMT：语句监视器（用于动态 SQL）</li>
<li>DFT_MON_TABLE：表监视器</li>
<li>DFT_MON_LOCK：锁监视器</li>
<li>DFT_MON_BUFPOOL：缓冲池监视器</li>
<li>DFT_MON_SORT：排序监视器</li>
<li>DFT_MON_UOW：工作单元信息</li>
<li>DFT_MON_TIMESTAMP：跟踪时间戳记信息</li>
</ul>
<p>这些开关的值存储在数据库管理器配置信息中。下面是数据库管理器配置参数：</p>
<img src="images/s5_i3_1_monList.gif" alt="dbm cfg 监视器开关字段"><p>监视器开关的设置方法就象设置任何其它实例配置参数一样：</p>
<pre>
<code style="font-family: Courier New, Courier, monospace; font-size: 12">
db2 update dbm cfg using monitorSwitch [ON | OFF]
</code>
</pre>
<p>
下面是一个示例：</p>
<pre>
<code style="font-family: Courier New, Courier, monospace; font-size: 12">
db2 update dbm cfg using DFT_MON_SORT ON
</code>
</pre>
<p>
						
<b>方法 2：在应用程序级别上设置监视器开关</b>
					
</p>
<p>也可以在应用程序级别上设置监视器开关；用这种方法设置开关只适用于特定的应用程序。如果您在命令提示符或命令窗口中使用下面列出的方法，那么所做的更改将只适用于这个特定的提示符窗口。</p>
<p>
下面是开关名称：</p>
<ul>
<li>Bufferpool</li>
<li>Lock</li>
<li>Sort</li>
<li>Statement</li>
<li>Table</li>
<li>Timestamp</li>
<li>UOW</li>
</ul>
<p>
使用下列命令以列出开关：</p>
<pre>
<code style="font-family: Courier New, Courier, monospace; font-size: 12">
db2 get monitor switches
</code>
</pre>
<p>
使用下列命令设置开关：</p>
<pre>
<code style="font-family: Courier New, Courier, monospace; font-size: 12">
db2 update monitor switches using switchName [ON | OFF]
</code>
</pre>
<p>
下面是开关更改的作用域比较：</p>
<img src="images/s5_i3_2_monSetComp.gif" alt="开关作用域图"><p>
						
<b>注：</b>您可能注意到了，设置监视器开关的语法与设置实例和数据库参数的语法非常类似。绝大多数配置命令语法都相同，只是在参数方面有区别。</p>
