Deploying Software and Updates
Deploying update packages automatically with global updating
1 Click Menu | Configuration | Server Settings, select Global Updating, then click
Edit at the bottom of the page.
Figure 9: Edit Global Updating page
2 On the Edit Global Updating page next to Status, select Enabled.
3 Edit the Randomization interval, if desired. The default is 20 minutes.
Each client update occurs at a randomly selected time within the randomization interval,
which helps distribute network load. For example, if you update 1000 clients using the
default randomization interval of 20 minutes, roughly 50 clients update each minute during
the interval, lowering the load on your network and on your server. Without the
randomization, all 1000 clients would try to update simultaneously.
4 Next to Packages types, select which packages initiate an update.
Global updating initiates an update only if new packages for the components specified here
are checked in to the master repository or moved to another branch. Select these
components carefully.
Signatures and engines — Select Host Intrusion Prevention Content, if needed.
NOTE: Selecting a package type determines what initiates a global update (not what is
updated during the global update process). Agents receive a list of updated packages during
the global update process. The agents use this list to install only updates that are needed.
For example, agents only update packages that have changed since the last update and
not all packages if they have not changed.
5 When finished, click Save.
Once enabled, global updating initiates an update the next time you check in any of the
selected packages or move them to another branch.
NOTE: Be sure to run a Pull Now task and schedule a recurring Repository Pull server task,
when you are ready for the automatic updating to begin.
