VCP5-DT Objective 3.4–Configure Local Mode Use

Objective 3.4 – Configure Local Mode Use

For this objective I used the following resources:

  • VMware View Administration documentation

Short post as most of this objective is around settings in either View Administrator or Group Policy Object’s (GPO’s).

Knowledge

Given a Customer Environment and Requirements, Apply Compatible Local Mode Pool Settings

Local mode is enabled and configured under the “Global Policies” settings via View Administrator:

Local-Mode

Policy Description
Local Mode Determines whether users can check out desktops for local use. Also determines whether users can run local desktops while the desktops are checked out.
The default value is Allow.
If you change this value to Deny while a desktop is checked out, the user cannot run the desktop in local mode, and the desktop cannot be used remotely because it is still checked out.
User-Initiated Rollback Determines whether users can discard a local desktop and revert to the remote version.
When a user initiates the rollback process, the lock on the remote desktop is released and the local desktop is discarded. If necessary, the user can manually remove and delete the local folder that contains the local desktop
data.
The default value is Allow.
Max Time Without Server Contact Specifies the amount of time in days that a local desktop can run without making contact with View Connection Server for policy updates. If the specified time limit is exceeded, View Client displays a warning message to the user and suspends the desktop.
The default value is 7 days.
On the client side, this expiration policy is stored in a file that is encrypted by a key that is built into the application. This built-in key prevents users who have access to the password from circumventing the expiration policy.
Target Replication Frequency Specifies the interval in days, hours, or minutes between the start of one replication and the start of the next replication. A replication copies any changes in local desktop files to the corresponding remote desktop or View Composer persistent disk in the datacenter.
The default value is the No replication setting. If you select At a specified interval, the default replication interval is 12 hours.
You can prohibit scheduled replications by selecting No replication.
The No replication policy does not prohibit explicit replication requests. You can initiate replications in View Administrator, and users can request replications if the User initiated replication policy is set to Allow.
If a replication takes longer than the interval that is specified in the Target replication frequency policy, the next scheduled replication starts after the
previous one is completed. The pending replication does not cancel the previous one.
For example, the Target replication frequency policy might be set to one day. A replication might start at noon on Tuesday. If the client computer is disconnected from the network, the replication might take longer than 24 hours. At noon on Wednesday, View Client with Local Mode starts the next
replication request. After the previous replication is completed, View Client with Local Mode takes a snapshot and starts the pending replication.
User Deferred Replication Determines whether users can pause active replications. If you enable this policy, a user can defer a replication that is underway. The replication does
not resume, and no new replications start, until the deferment period is
over.
The default value is Deny. When the value is set to Allow, the deferment period is two hours.
Disks Replicated Determine which desktop disks are replicated. This policy affects View Composer linked-clone desktops only. For full virtual-machine desktops,, all disks are replicated.
You have these disk-replication choices:

  • Persistent Disks
  • OS Disks
  • OS and Persistent Disks

Changing this policy affects desktop replication after the next checkout occurs. A change does not affect desktops that are currently checked out.
The default value is Persistent disks.

 

User-Initiated Check In Determines whether users are allowed to check in desktops that are running in local mode.
The default value is Allow.
User-Initiated Replication Determines whether users are allowed to initiate replications from their desktops when they run in local mode.
The default value is Allow.

 

There are also a couple of settings that can be configured through the vdm_client.adm GPO template:

Local-Mode-GPO

  • Default exit behavior for Local Mode desktops – Controls the default exit behavior of desktops that are running in local mode. The default setting is Shutdown, which causes the guest operating system to shut down
  • Delay the start of replications when starting the View Client with Local Mode – Specifies the number of seconds to delay the start of replication after View Client with Local Mode starts. A replication copies any changes in local desktop files to the corresponding remote desktop. The default  delay period is 900 seconds (15 minutes).
  • Redirect smart card readers in Local Mode – Determines whether smart card readers are redirect to local desktops. The readers are shared with the client system. This setting is enabled by default.

Happy Studying!
