<p>在oracle 未正式对外公布的20c版本中已经提及在该版本及其以后版本中不再支持no-cdb模式<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2021/08/20210814204946.png"><img src="https://www.xifenfei.com/wp-content/uploads/2021/08/20210814204946.png" alt="20210814204946" width="1093" height="412" class="alignnone size-full wp-image-9427" /></a><br />
<hr />
在正式对外发布的21c版本中,dbca创建库的过程中确认只能选择cdb模式(灰色,无法去掉)<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2021/08/20210814135605.png"><img src="https://www.xifenfei.com/wp-content/uploads/2021/08/20210814135605.png" alt="20210814135605" width="797" height="607" class="alignnone size-full wp-image-9429" /></a><br />
<hr />
尝试启动实例设置enable_pluggable_database=false,实例无法启动<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2021/08/20210814213023.png"><img src="https://www.xifenfei.com/wp-content/uploads/2021/08/20210814213023.png" alt="20210814213023" width="1008" height="115" class="alignnone size-full wp-image-9430" /></a><br />
<hr />
证明21c是从软件代码中强制加入了enable_pluggable_database=true参数验证,数据库必须使用cdb模式</p>
