DB version: 12.2
OS : Oracle Linux 7.4
I have 5 production PDBs in the below mentioned CDB (its named CDB4 ) . Due to a hardware problem, I wanted to quickly 'close' all the PDBs. Instead, I just shutdown the CBD as shown below.
Is it recommended to shutdown the CDB without individually closing each PDBs ?
[oracle@mndcrac215 ~]$ . oraenv
ORACLE_SID = [oracle] ? CDB4
The Oracle base has been set to /u01/app/oracle
[oracle@mndcrac215 ~]$ sqlplus / as sysdba
