Shared Queue Server panel

important

Atom Queues are now Legacy. We recommend using Event Streams for your event-based and messaging use cases.

The Shared Queue Server panel appears on the Runtime Management page (Manage > Runtime Management). This panel is used to configure the selected Runtime’s message queue server settings.

note

You must have the Runtime Management privilege to configure message queue server settings. If you have the Runtime Management Read Access privilege, you can view the settings but you cannot change them.

Configuring the Shared Queue Server Panel
