The idea behind the PPM group operation mechanism is to give users the ability to execute various operations with packages – installation, upgrade and uninstallation – simultaneously on several hosts in the system. The group operation represents a set of individual tasks, that is, package operations for a single host. Executing a group operation means executing all the tasks included in the group operation.
The tasks inside a group operation are considered independent meaning some may be completed and some may fail. Failure of tasks does not imply failure in the group operation execution. As all package operations are executed as background tasks, you can view the results the user interface at Operations > Tasks > Background tab > Scheduled Tasks subtab.
Important: Group operation supports only fully automated packaging operations, which does not require on per-package interaction with a user (such as the necessity to edit mandatory package properties or view the license before installation). This means that packages that are not installable with default properties are not supported by PPM group operations. Use single package installation for such cases.
