''''''' Heading 4
(Avoid deeper levels because they do not render well.)
Alembic-migration
=================
Using alembic-migration, required data modeling for networking-sfc is defined and
applied to the database. Refer to `Neutron alembic migration process <http://docs.openstack.org/developer/neutron/devref/alembic_migrations.html>`_ for further details.
Important operations:
---------------------
Checking migration:
~~~~~~~~~~~~~~~~~~~
::
neutron-db-manage --subproject networking-sfc check_migration
Running branches for networking-sfc ...
start_networking_sfc (branchpoint)
-> 48072cb59133 (contract) (head)
-> 24fc7241aa5 (expand)
OK
Checking branch information:
~~~~~~~~~~~~~~~~~~~~~~~~~~~
::
neutron-db-manage --subproject networking-sfc branches
Running branches for networking-sfc ...
start_networking_sfc (branchpoint)
-> 48072cb59133 (contract) (head)
-> 24fc7241aa5 (expand)
OK
Checking migration history:
~~~~~~~~~~~~~~~~~~~~~~~~~~~
::
neutron-db-manage --subproject networking-sfc history
Running history for networking-sfc ...
9768e6a66c9 -> 5a475fc853e6 (expand) (head), Defining OVS data-model
24fc7241aa5 -> 9768e6a66c9 (expand), Defining flow-classifier data-model
start_networking_sfc -> 24fc7241aa5 (expand), Defining Port Chain data-model.
start_networking_sfc -> 48072cb59133 (contract) (head), Initial Liberty no-op script.
<base> -> start_networking_sfc (branchpoint), start networking-sfc chain
Applying changes:
~~~~~~~~~~~~~~~~~
::
neutron-db-manage --subproject networking-sfc upgrade head
INFO [alembic.runtime.migration] Context impl MySQLImpl.
INFO [alembic.runtime.migration] Will assume non-transactional DDL.
Running upgrade for networking-sfc ...
INFO [alembic.runtime.migration] Context impl MySQLImpl.
INFO [alembic.runtime.migration] Will assume non-transactional DDL.
INFO [alembic.runtime.migration] Running upgrade -> start_networking_sfc, start networking-sfc chain
INFO [alembic.runtime.migration] Running upgrade start_networking_sfc -> 48072cb59133, Initial Liberty no-op script.
INFO [alembic.runtime.migration] Running upgrade start_networking_sfc -> 24fc7241aa5, Defining Port Chain data-model.
INFO [alembic.runtime.migration] Running upgrade 24fc7241aa5 -> 9768e6a66c9, Defining flow-classifier data-model
INFO [alembic.runtime.migration] Running upgrade 9768e6a66c9 -> 5a475fc853e6, Defining OVS data-model
OK
Checking current version:
~~~~~~~~~~~~~~~~~~~~~~~~~
::
neutron-db-manage --subproject networking-sfc current
Running current for networking-sfc ...
INFO [alembic.runtime.migration] Context impl MySQLImpl.
INFO [alembic.runtime.migration] Will assume non-transactional DDL.
