<content type="html"><![CDATA[<p>工作中有个从测试数据库到生产数据库的数据迁移需求,因为是新项目,目前生产区和测试区还没有做隔离
所以我考虑利用data pump和database link做数据迁移,只要1条impdp命令就可以实现</p>
<p>首先创建目标库到测试库的database link</p>
<figure class='code'><figcaption><span>create database link </span></figcaption>
<div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='bash'><span class='line'>SQL> create public database link rac1_bm_lk connect to bm_zny identified by <span class="s2">"123456"</span> using <span class="s1">'172.20.101.202:1521/testdb'</span>;
</span></code></pre></td></tr></table></div></figure>
<p>然后赋予目标库帐号imp_full_database角色 (之前帐号需要有connect ,resource角色)</p>
<figure class='code'><figcaption><span>grant imp_full_database </span></figcaption>
<div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='bash'><span class='line'>SQL> grant imp_full_database to testme;
</span></code></pre></td></tr></table></div></figure>
<p>进行导入操作</p>
<figure class='code'><figcaption><span>impdp import data </span></figcaption>
<div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>

<content type="html"><![CDATA[<p><strong>首先是蜜豆的做法：</strong></p>
<pre><code>1. 将赤豆用水泡24小时（我因为断煤气泡了36个小时- -）
2. 1份赤豆3份水，将水烧开倒入赤豆，烧开转小火煮
3. 水烧到1/3后加糖，可以是冰糖（我加了红糖)
4. 烧到水快干了就做好了
</code></pre>
<hr />
<p><strong>下面是双皮奶的做法：</strong></p>
<pre><code>1. 200ML牛奶，小火煮到快开不开状态，倒入碗中放冰箱凉出奶皮
2. 1个鸡蛋分出蛋清，打碎加入10G糖
3. 将牛奶倒入蛋清混合均匀（奶皮留原来碗里）
4. 将3中混合物倒回碗里，隔水蒸10分钟
5. 放凉加蜜豆，功成
</code></pre>
<p>糖不需要太多，甜味靠蜜豆，双皮奶嫩滑有浓郁的奶味，蜜豆咬起来非常软，很好吃</p>
