今天就跟大家聊聊有关oracle 12c PDB随CDB启动以及链接PDB的方式是什么，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

本来不知道有这个特性写了个trigger实现

sql_startup_pdb:='alter pluggable database test open';
EXECUTE IMMEDIATE sql_startup_pdb;
end;
/
12R2可以设置如下自动启动pdb
ALTER PLUGGABLE DATABASE test SAVE STATE;
select con_name, state from dba_pdb_saved_statesCON_NAME STATE
------------------------------ --------------
TEST OPEN

详细信息可以参考以下文章：

How to Preserve Open Mode of PDBs When the CDB Restarts (Doc ID 1933511.1)

和连接pdb的方式
