To ensure that Linux, UNIX, and Windows managed machines always include the latest patches, you
can have VCM deploy patches to the managed machines when certain events occur in your
environment. After you perform the initial configuration for the automatic deployment, no
intervention is required to deploy patches to managed machines.
5. "Configure VCM for Automatic Scheduled Patch Assessment and Deployment" on page 176
To ensure that Linux, UNIX, and Windows managed machines are updated with the latest patches on a
regular basis, you can schedule VCM to deploy patches to the managed machines. The automatic
scheduled patch assessment and deployment matches a machine group to a patch assessment
template.
What to do next
n
For Linux and UNIX patching, after a job triggers, view the job chain in the VCM Job Manager, and the
finished job chain jobs in Job Manager History. See "How the Linux and UNIX Patching Job Chain
Works" on page 178.
n
(Optional) You can schedule an automatic patch deployment. See "Configure VCM for Automatic
Scheduled Patch Assessment and Deployment" on page 176.
Configuring the Patching Repository Machine
To patch managed Linux and UNIX machines, you must install a Red Hat Linux 6, 64-bit machine as the
patching repository, configure the communication protocols, and download and configure the Software
Contentī ±Repository (SCR) Tool.
CAUTION To ensure security in a geographically distributed Linux and UNIX patching
environment, the credentials that you use to transfer patches from the patching repository to the
alternate location must be different from the credentials that you use to copy patches from the
alternate location to the target managed machines. The credentials used to transfer patch files to the
alternate location must have read and write privileges. Use read-only credentials to stage patches
from an alternate location to a managed machine.
If you already configured the Red Hat Linux patching repository machine for manual patching with VCM,
you can skip this procedure.
Prerequisites
n
Verify that the Red Hat Linux patching repository machine can access the Internet.
n
When you set up a patching repository machine and alternate location machines, you must ensure that
users have proper permissions and protocols configured to read patches from the patching repository
machine and write patches to the alternate location machines. See "Communication Protocols to Stage
Linux and UNIX Patches" on page 159.
n
Decide which protocol to use to copy patches from the patching repository machine to the optional
alternate location machines. To configure the protocol, see http://kb.vmware.com/kb/2051632 and the
Red Hat Linux information online.
