CLI cookbook: Migrating an Oracle RAC virtual PDB and a virtual CDB

Delphix supports migrating from a RAC vPDB in a virtual CDB, to another RAC linked CDB or virtual CDB. This feature is only available through the command-line interface.

Attempts to perform this migration via GUI will fail with the following error:

Error
The operation could not be completed because the virtual database “vPDB1" is disabled.
Error Code
exception.db.genericvdb.disabled

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

Pre-requisites

You should already be 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.

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 racPDB
   delphix source 'racPDB'> disable
   delphix source 'racPDB' disable *> commit
       Dispatched job JOB-74
       SOURCE_DISABLE job started for "racPDB".
       Disabling virtual database "racPDB".
       Unexporting storage containers.
       Virtual database "racPDB" disabled.
       SOURCE_DISABLE job for "racPDB" completed successfully.

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

   CODE

   delphix source 'racPDB'> /sourceconfig/
   delphix sourceconfig> select racPDB
   delphix sourceconfig 'racPDB'> update
   delphix sourceconfig 'racPDB' update *> set repository='/u01/app/oracle/product/12.1.0.2/dbhome_1'
   delphix sourceconfig 'racPDB' update *> set environmentUser=' /oracle'
   delphix sourceconfig 'racPDB' update *> commit
       Dispatched job JOB-76
       SOURCE_CONFIG_UPDATE job started for "racPDB".
       SOURCE_CONFIG_UPDATE job for "racPDB" 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. The instance configuration must also be configured for the new hosts.

   CODE

   delphix sourceconfig 'racPDB'> /sourceconfig/
   delphix sourceconfig> select racCDB
   delphix sourceconfig 'racCDB'> update
   delphix sourceconfig 'racCDB' update *> set repository='/u01/app/oracle/product/12.1.0.2/dbhome_1'
   delphix sourceconfig 'racCDB' update *> set environmentUser=' /oracle'
   delphix sourceconfig 'racCDB' update *> edit instances
   delphix sourceconfig 'racCDB' update instances *> ls
   Properties
       0:
           type: OracleRACInstance
           instanceName: racCDB1
           instanceNumber: 1
           node: mwtestx1    1:
           type: OracleRACInstance
           instanceName: racCDB2
           instanceNumber: 2
           node: mwtestx2Use the "add" command to add an element to this array.
   delphix sourceconfig 'racCDB' update instances *> set 0.node=mwtestz1
   delphix sourceconfig 'racCDB' update instances *> set 1.node=mwtestz2
   delphix sourceconfig 'racCDB' update instances *> commit
       Dispatched job JOB-77
       SOURCE_CONFIG_UPDATE job started for "racCDB".
       SOURCE_CONFIG_UPDATE job for "racCDB" completed successfully.

5. Enable the vPDB.

   CODE

   delphix sourceconfig 'racCDB'> /sourced
   elphix source> select racPDB
   delphix source 'racPDB'> enable
   delphix source 'racPDB' enable *> commit
       Dispatched job JOB-78
