Gouranga's Tech Blog: Restore and Recover entire CDB in different host using Oracle 12c

We will discuss:
1) Complete CDB restore in different host
and..
2) Create new PDBs
3) Change all PDB passwords for container in one go
4) 12c Networking, Connecting PDBs via oracle client

About CDB and PDB:

Recovery of CDB, ROOT and PDB Database in 12c can be performed at the CDB container level (with ALL PDBs), ROOT or as at the individual PDB level. For the recovery at the CDB level, obviously the backups for ALL the PDBs must be present. Conversely it does not matter whether the backups, were taken at the CDB level (with all PDBs) or backups performed for individual PDBs. RMAN will automatically choose the appropriate backup sets to recover some or all the databases, as instructed. Let’s look at how a recovery of a CDB and PDB can be performed in Oracle 12C, multi-tenant environment.

1) Complete CDB restore in different host

3) Change all PDB passwords for container in one go:

How to change Pluggable DB's SYS password?

-- To set a common password for SYS and SYSTEM users across all PDBs

SQL> alter user SYS identified by oracle container=all;
User altered.

SQL> select name,open_mode from v$database;

NAME OPEN_MODE
--------- --------------------
CDB READ WRITE
SQL>

-- Switch to different container

SQL> alter session set container = PDB1;
Session altered.

SQL> show con_name
CON_NAME

SQL> alter session set container = PDB2;
Session altered.

SQL> show con_name
