Plugging an Unplugged Pluggable Database

Purpose

This tutorial covers the steps required to plug an unplugged pluggable database (PDB) from a container database (CDB) into another CDB.

Time to Complete

Approximately 20 minutes

Introduction

You can disassociate or unplug a PDB from a CDB and reassociate or plug the PDB into the same CDB or into another CDB. This capability is suitable for the following situations:

    • You have to upgrade a PDB to the latest Oracle version, but you do not want to apply it on all PDBs. Instead of upgrading a CDB from one release to another, you can unplug a PDB from one Oracle Database release, and then plug it into a newly created CDB from a later release.
    • You want to test the performance of the CDB without a particular PDB. You unplug the PDB, test the performance without the PDB and, if necessary, replug the PDB into the CDB.
    • You want to maintain a collection of PDB “gold images” as unplugged PDBs.
Scenario

In this tutorial, you perform a PDB unplugging operation from a CDB. Next, you perform a plugging operation of the same PDB into another CDB by using SQL*Plus.

Different plugging scenarios are allowed:

      • Plug the unplugged PDB by using the data files of the unplugged PDB. The unplugged PDB is disassociated from the source CDB.
        • The source data files are used with or without any copy.
        • The source data files are used after being moved to another location.
      • Plug the unplugged PDB as a clone to:
        • Allow developers and testers to rapidly and repeatedly provision a well-known starting state
        • Support self-paced learning
        • Provide a new way to deliver a brand-new application
Prerequisites

Before starting this tutorial, you should:

  • Install Oracle Database 12c.
  • Create two CDBs with two PDBs in the first CDB.

The environment used in the development of this tutorial is as follows:

    • ORACLE_HOME: /u01/app/oracle/product/12.1.0
    • TNS Listener port: 1521
    • Container databases:
      • SID: cdb1
      • SID: cdb2
    • Pluggable databases (in cdb1):
      • pdb1
      • pdb2

Performing Basic Tasks in Oracle Multitenant

Purpose

This tutorial covers the steps to perform basic tasks on container databases (CDBs) and pluggable databases (PDBs).

Time to Complete

Approximately 45 minutes

Introduction

This tutorial shows you how to:

    • Connect to a CDB and to a PDB.
    • Create a PDB from the seed PDB.
    • Manage CDBs and PDBs.
      • Start a CDB, understand the different open modes of PDBs, and shut down a CDB.
      • Open and close PDBs.
      • Change the name of a PDB.
    • Manage the storage in a CDB and its PDBs.
      • Manage permanent tablespaces.
      • Manage temporary tablespaces.
    • Manage the security in PDBs.
      • Create common and local users.
      • Create common and local roles.
      • Grant common and local privileges.
    • Drop PDBs.

Note: For readability, formatting was applied to some columns shown in the output.
