If the configuration of the yum repository server has been changed, the yum caches for Linux business servers (yum clients) must be cleared. If the yum cache needs to be cleared, execute the swcfmg_notify_yumcacheclean command (the yum cache cleanup notification command). Refer to the Reference Guide for information on the swcfmg_notify_yumcacheclean command (the yum cache cleanup notification command).
Cases where the yum caches for Linux business servers (yum clients) must be cleared:
When a repository server has been added or removed
When a RPM package has been added or removed
When the storage destinations for RPM packages have been changed (added or removed)
When the communication protocols used between the repository server and yum clients have been changed (added or removed)
These operations are performed by infrastructure administrators.
Note
Do not decide whether to clear the yum caches for Linux business servers (yum clients) based on messages etc. The infrastructure administrator that manages the yum repository server must always execute the yum cache cleanup notification command whenever the configuration of the yum repository server is changed.
If the configuration of the yum repository server is changed but the yum cache cleanup notification command is not executed, then historic information will be displayed in the management console for the application status of Linux patches, even if discovery is performed.
If RPM packages have been registered with the yum repository server and set in the Linux patch management target definitions but the Linux patch information in the management console does not show the RPM packages that should have been registered with the yum repository server, then it is possible that the yum caches on Linux business servers have not been recreated. Perform discovery after executing the yum cache cleanup notification command. Refer to "2.5.2 Defining the Linux Patch Management Target" for information on how to define the Linux patch management target.
If the RPM packages registered with the yum repository server are still not displayed in the patch list in the management console, this means that no Linux business servers to which these RPM packages can be applied have been deployed at the moment.
