DUP Dependencies

DRM 1.9 onwards, DRM supports DUP Dependency. This feature articulates the relationship between two

different DUPs. SUU enables certain rules and submissions to determine if a set of conditions or

requirements are met. These conditions or requirements are called dependencies. Dependency exists

when a DUP of a particular kind has a dependence on additional DUP for further execution. This helps the

users to determine, which DUP to install first and which one to follow. There are two types of

dependencies: Hard Dependency and Soft Dependency.

• Hard Dependency — Dependency that must be applied in order to be able to apply the update.

• Soft Dependency — Dependency that needs to be applied in order to use certain new features

coming with the update.

NOTE: In certain scenarios, for a complete update or upgrade, you have to install two and more

DUPs. It is possible that for individual DUPs, you are forced to restart the system, to realize the

impact of other installed DUPs.

• When you update a component, if the dependent component is a pre-requisite and it needs a reboot,

it is recommended to reboot the system to update the remaining components.

• When you import components using Import option, if the component has a missing dependency a

warning message is displayed informing you about the missing dependency.

• When you choose the Export option, the pre-requisite components are downloaded and copied to

the output location.
