When you start to use application edition manager, you might come
across some questions about the application edition manager functionality.
Can the application edition manager ensure interruption-free
application upgrade for workloads that are driven by Internet InterORB Protocol
(IIOP) or Java Message Service (JMS) protocols?
No.
The application edition manager can ensure interruption-free application upgrades
only for workloads managed by the on demand router (ODR). The ODR supports
HTTP and HTTPS only.
Can the application edition manager ensure interruption-free
application upgrades for workloads that include calls between Java 2
Platform, Enterprise Edition (J2EE) Version
5 applications?
Yes, the application edition manager can ensure
an interruption-free update if each interapplication request uses HTTP or
HTTPS protocol through an on demand router.
Can the application edition manager ensure interruption-free
application upgrades for workloads that are hosted on static clusters?
Yes,
if an on demand router is managing the work sent to that static cluster.
Can the application edition manager support the deployment
of one edition of an application to one cluster and the deployment of another
edition to a different cluster?
Yes. The application edition manager
supports different editions simultaneously deployed on different targets.
You must establish routing policies for routing traffic to different editions.
Does the application edition manager support the activation
of different editions on different members of the same cluster?
No.
Does the application edition manager restart the application
or the entire server to activate a new edition?
No, the application
edition manager does not restart the application or server. You must perform
the following steps:
- Stop the active edition.
- Deactivate the active edition.
- Activate the new edition.
- Start the new edition.
Can the application edition manager handle the rollout of
editions with incompatible changes?
Yes, the application edition
manager can handle this situation if the on demand router is configured to
perform edition-aware routing. See Edition compatibility
.
Can the application edition manager handle the rollout of
editions that include database schema changes?
Yes, you can perform
rollout of editions that include database schema changes if the database changes
are compatible with earlier versions.
