Client-based dependency resolving offers you the following benefits:
- More stable and precise ability to resolve dependencies on client Red Hat Linux and SUSE Linux computers.
- No delays in software update policy creation because dependency resolving is not required at this stage. Only the updates that are selected for distribution are added to a software update policy.
- Optimization of the network traffic and disk space that is used on Notification Server, package servers, and client computers.
- During the staging of software bulletins, Patch Management Solution downloads all the updates that are included into the bulletins. However, after the client-based dependency resolving is completed, the additional download occurs only for the dependent software update packages that are required on a specific client computer.
Note that the client-based dependency resolving has the following limitations:
- You experience the following behavior on the client computers with legacy versions (less than 8.1) of the software update plug-in:
- The software updates with dependencies can be installed on such computers if they run the software update policy created before the upgrade to 8.1, and the list of software updates included into the policy is not changed in 8.1.
For example, the list of software updates may be changed when you check the option Automatically revise Software Update policies after importing patch data on the Import Patch Data page.
- Only the software updates with no dependencies can be installed on such computers if they run the software update policy that is created after the upgrade to 8.1.
To benefit from the client-based dependency resolving feature, upgrade the software update plug-in to the 8.1 version on such computers.
- Patch Management Solution uses Linux native tools Yum and Zypper to resolve and install dependent software update packages. If these tools have the known issues that cause incorrect dependency resolving, Patch Management Solution will experience the same behavior.
- As soon as the client-based dependency resolving is completed, the additional download tasks are created for the dependent software update packages that are required on a specific client computer. Only one instance of a download task may run at same time for Windows and Linux software update packages. A queue of download tasks may appear on Notification Server or a package server, and dependent software update packages may be downloaded with a delay.
