SAS Model Manager administrators
can freeze a project version to prevent users from modifying some
properties and files for the version’s models. A version is
frozen when the champion model in a version folder is approved for
production or is pending approval. After a version is frozen, the
Models folder
is locked so that SAS Model Manager advanced users cannot perform
the following tasks:
-
-
modify version or model properties
-
add, delete, or modify model objects
-
change the champion model
SAS Model Manager administrators
remain authorized to perform these activities. If the champion model
is not deployed to an operational environment, then a SAS Model Manager
administrator can unfreeze a frozen version so that users can change
the models. SAS Model Manager advanced users can still modify the
Documents,
Reports,
Resources,
and
Scoring Tasks folders after a version
is frozen.
When the champion model
has been used in production scoring and you must change the contents
of a frozen default version, unfreeze the default version. However,
use caution modifying the version content. If the model UUID and
revision number for the score code in production scoring environments
are always recorded, then you can modify a version even after the
version is deployed to production environment.
These are the tasks
that you perform to control access to project version:
If you attempt to delete
a project that contains a frozen version, SAS Model Manager displays
a message indicating that you cannot delete a project that contains
frozen versions. You must have a SAS Model Manager administrator unfreeze
the versions before the project can be deleted.
