Change Center

The Change Center allows for team collaboration when services and metadata are being configured in ALSB. Each user works in a sandbox session until the user is ready to check in the working configuration to the core configuration of the bus. The change center provides multiple levels of undo, and visibility into conflicts, as multiple users work on the configuration.

Most of the Change Center pages display different information based on whether you are in a session (that is, you have clicked Create or Edit in the Change Center) or outside a session. For example, in a session, the View Configuration Changes page lists all the changes you have made in that session; outside a session, the page lists all session activations.

Table 2-1 displays Change Center tasks and related session information.

Session Information
View conflicts
Inside session only: This link displays the number of conflicts occurring in a session. View and resolve all conflicts between changes in the current session and those made by all other sessions within the ALSB Console. A conflict occurs if a resource modified in the current session has already been modified and activated by another session. Two changes to the same resource by two sessions do not cause a conflict until one of the sessions is activated.
This page also displays semantic errors for resources in the session.
View changes
Inside session: View the configuration changes you have made during the current session.
Outside session: View configuration changes that are caused by previous session activations.
Undo changes
