CLI cookbook: Migrating a virtual PDB in a virtual CDB

Delphix supports migrating from a vPDB in a virtual CDB, to another linked or virtual CDB. 

This topic describes how to migrate a virtual pluggable database (vPDB) in a virtual CDB to another virtual CDB using the command-line interface.

Pre-requisites

• You should already set up and have Delphix discover a container database in the same environment as the vPDB currently is or from an environment to which the vPDB will be migrated to.

• If the Automatic VDB Restart feature is enabled for the vPDB and the target container database is a virtual CDB, before migration, you should ensure that either the Automatic Restart feature is also enabled for the target virtual CDB or the feature is disabled for the vPDB.

Procedure

1. Log into the Delphix command-line interface using the admin user or a user with admin privileges.

   CODE

   ssh admin@YOUR_ENGINE

2. Disable the vPDB.

   CODE

   delphix> /source
   delphix source> select myPDB
   delphix source 'myPDB'> disable
   delphix source 'myPDB' disable *> commit
       Dispatched job JOB-35
       SOURCE_DISABLE job started for "myPDB".
       Disabling virtual database "myPDB".
       Unexporting storage containers.    Virtual database "myPDB" disabled.
       SOURCE_DISABLE job for "myPDB" completed successfully.
   delphix source 'myPDB'>

3. Change the environment user and repository ( ORACLE_HOME ) for the vPDB to the appropriate user from the new host.

   CODE

   delphix> /sourceconfig
   delphix sourceconfig> select myPDB
   delphix sourceconfig 'myPDB'> update
   delphix sourceconfig 'myPDB' update *> set repository='/u01/app/oracle/product/19.0.0.0/dbhome_1'
   delphix sourceconfig 'myPDB' update *> set environmentUser='/oracle'
   delphix sourceconfig 'myPDB' update *> commit
       Dispatched job JOB-38
       SOURCE_CONFIG_UPDATE job started for "myPDB".
       SOURCE_CONFIG_UPDATE job for "myPDB" completed successfully.

4. Change the environment user and repository ( ORACLE_HOME ) for the vCDB to the appropriate user from the new host. This must match the settings in step 3.

   CODE

   delphix sourceconfig 'myPDB'> /sourceconfig/
   delphix sourceconfig> select myCDB
   delphix sourceconfig 'myCDB'> update
   delphix sourceconfig 'myCDB' update *> set repository='/u01/app/oracle/product/19.0.0.0/dbhome_1'
   delphix sourceconfig 'myCDB' update *> set environmentUser='/oracle'
   delphix sourceconfig 'myCDB' update *> commit
       Dispatched job JOB-39
       SOURCE_CONFIG_UPDATE job started for "myCDB".
       SOURCE_CONFIG_UPDATE job for "myCDB" completed successfully.

5. Enable the vPDB.

   CODE

   delphix sourceconfig 'myCDB'> /source
   delphix source> select myPDB
   delphix source 'myPDB'> enable
   delphix source 'myPDB' enable *> commit
       Dispatched job JOB-40
       SOURCE_ENABLE job started for "myPDB".

       Virtual database "myCDB" was successfully started.
       Starting virtual database.
       Starting instance 1 on virtual database "myPDB".
