Software Upgrades
A useful feature of the GC is the capability to deploy new software and rules updates automatically across multiple local controllers.
When you click the ADMIN button, click the System Maintenance tab, and then click the Upgrade button, you see a page like Figure 12-16. On this page, if you're using the web interface for upgrading your software, you can optionally select LCs to be upgraded at the same time as the GC is upgraded.

Status Vers ¡Proxy Information Proxy Settings |ZonB Addrt Status Vers ¡Proxy Information Proxy Settings I O Back I I Install o Local mStatus messages during the upgrade are not very informative. In fact, all you see is the message "Installation in progress." When you see this message, such as that shown in Figure 12-17, close your browser and wait for 30 minutes or so. The upgrade can take some time for the global controller. Also, depending on connectivity to the local controllers, it could take anywhere from about the same time as the GC to a few hours. It's a good idea to perform upgrades during defined maintenance hours. Your GC and LC will continue to process data during the time period that the upgrade file is transferring, but it will stop processing for a period of time to perform the upgrade.

The upgrade occurs on the GC first and then on the LC. During the time period that the GC is unavailable, data continues to be processed on the LC. When the GC becomes available again, any data is transferred to the GC. When you select one or more LCs to upgrade while the GC is upgrading, the GC downloads software from the designated network location, using either FTP or HTTPS. The software is then downloaded automatically by the LCs from the GC. If network connectivity is slow across these links, the upgrade could take a significant amount of time. |
