CDB的启动和关闭

CDB的启动和关闭和以前数据库的启动和关闭一样，启动CDB将启动整个实例，关闭CDB将关闭整个实例。PDB的启动和关闭并不关闭或者启动实例。

查看数据库是不是CDB

SQL> SELECT CDB FROM V$DATABASE;

CDB

---

YES

得到当前容器的名字

SQL> SELECT SYS_CONTEXT ('USERENV', 'CON_NAME') FROM DUAL;

SYS_CONTEXT('USERENV','CON_NAME')

查看有多少个容器

SQL> COLUMN NAME FORMAT A8

SQL> SELECT NAME, CON_ID, DBID, CON_UID, GUID FROM V$CONTAINERS ORDER BY CON_ID;
