For example, a single baseline may be captured on February 5, 2009 from 5:00 p.m. to 8:00 p.m.</p> <p>You can choose future start and end times to create a baseline that captures future database activity. If both the start time and the end time are in the future, then a baseline template with the same name as the baseline will also be created. A <a id="sthref209" name="sthref209"></a>baseline template is a specification that enables Oracle Database to automatically generate a baseline for a future time period.</p> <p class="orderedlisttitle">To create a single baseline: </p> <ol> <li> <p>From the Database Home page, click <span class="bold">Server</span>.</p> <p>The Server page appears.</p> </li> <li> <p><a id="sthref211" name="sthref211"></a>Under Statistics Management, click <img src="shortcut.png" alt="callback" border="0" /><a href="javascript:void(0);" onclick="redirectEMpage('AWR_BASELINES_MAIN');"><span class="bold">AWR Baselines</span></a>.</p> <p>The AWR Baselines page appears with a list of existing baselines displayed.</p> </li> <li> <p>Click <span class="bold">Create</span>.</p> <p>The Create Baseline: Baseline Interval Type page appears.</p> </li> <li> <p>Select <span class="bold">Single</span>.</p> </li> <li> <p>Click <span class="bold">Continue</span>.</p> <p>The Create Baseline: Single Baseline page appears.</p> </li> <li> <p>In the <span class="bold">Baseline Name</span> field, enter a name for the baseline.</p> </li> <li> <p>Under Baseline Interval, select whether to use a snapshot range or a time range for the baseline.
