23.4. Taking a Site Offline

23.4.1. About Taking Sites Offline

In JBoss Data Grid's Cross-datacentre replication configuration, if backing up to one site fails a certain number of times during a time interval, that site can be marked as offline automatically. This feature removes the need for manual intervention by an administrator to mark the site as offline.
It is possible to configure JBoss Data Grid to take down a site automatically when specified confiscations are met, or for an administrator to manually take down a site:
  • Configure automatically taking a site offline:
    • Declaratively in Remote Client-Server mode.
    • Declaratively in Library mode.
    • Using the programmatic method.
  • Manually taking a site offline:
    • Using JBoss Operations Network (JON).
    • Using the JBoss Data Grid Command Line Interface (CLI).
