Edition manager frequently asked questions

This topic provides the answers to some frequently asked questions about the application edition manager.

Can the 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 edition manager can ensure interruption-free application upgrades only for workloads managed by the WebSphere Extended Deployment on demand router. The WebSphere Extended Deployment on demand router supports HTTP and HTTPS only.

Can the edition manager ensure interruption-free application upgrades for workloads that include calls between Java 2 Platform, Enterprise Edition (J2EE) applications?

Yes, if each interapplication request is HTTP or HTTPS through an on demand router.

Can the 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 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 edition manager support the activation of different editions on different members of the same server cluster?

No.

Does the edition manager restart the application or the entire server to activate a new edition?

No. You need to stop, then deactivate the currently active edition, activate the new edition, then start the new edition to restart the application on activation of a new edition.

Can the edition manager handle the rollout of editions with incompatible changes?

Yes, if the on demand router is configured to perform edition-aware routing. See Edition compatibility considerations .

Can the edition manager handle the rollout of editions that include database schema changes?

Yes, if the database changes are backward compatible.
