CLI cookbook: Migrating an Oracle RAC virtual PDB in 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.

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.
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

Log into the Delphix command-line interface using the admin user or a user with admin privileges.
CODE
```
ssh admin@YOUR_ENGINE
```

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.

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.

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

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.

Enable the vPDB.

delphix source 'racPDB'> enable
delphix source 'racPDB' enable *> commit
