Configuring The Heartbeat Interval For Local Desktop Client Computers - VMware View Manager 4.5 Admin Manual

Configure a Proxy Server to Cache View Composer Base Images
When you set up a proxy server to support HTTP caching for local desktops, you must configure the capacity
of the cache and the HTTP connection method.
Prerequisites
Verify the size limit of base-image package files that you set with the
n
the Size of Base-Image Package Files to Allow Caching,"
Determine whether you use SSL for local mode operations. See
n
Support HTTP Caching of View Composer Base Images,"
Procedure
1 Configure the maximum size of the cache on the proxy server.
To calculate the maximum size, consider the number and size of the View Composer base images that are
used by local desktops. The base images are downloaded as package files to the proxy server. Also consider
other files that you plan to cache on the proxy server.
2 Configure the size of the largest single file that can be cached.
The single-file maximum size on the proxy server must be at least as large as the maximum package-file
size that you set with the
3 If you do not enable the Use SSL for Local Mode operations setting for View Connection Server, set the
access control list (ACL) on the proxy server to open port 80 and allow the CONNECT method to connect
to port 80.
View Transfer Server uses the CONNECT method to provide a tunnel connection through the proxy
server. View Transfer Server uses this connection to transfer files and data other than View Composer
base images between local desktops and the datacenter. Using port 80 enhances transfer performance.

Configuring the Heartbeat Interval for Local Desktop Client Computers

Client computers that host local desktops send heartbeat messages to View Connection Server at regular
intervals to read the status of their checked-out desktops. The default heartbeat interval for all client computers
is five minutes. You can change the heartbeat interval for all client computers. You can also set a different
heartbeat interval for a specific client computer.
Change the Heartbeat Interval for All Local Desktop Client Computers
n
To change the heartbeat interval for all client computers that host local desktops, you use the ADSI Edit
utility to edit View LDAP on your View Connection Server host. The ADSI Edit utility is installed with
View Connection Server.
Set the Heartbeat Interval for a Specific Local Desktop Client Computer
n
To set the heartbeat interval for a specific client computer that hosts a local desktop, you use the Windows
Registry Editor to edit the system registry on that computer.
Change the Heartbeat Interval for All Local Desktop Client Computers
To change the heartbeat interval for all client computers that host local desktops, you use the ADSI Edit utility
to edit View LDAP on your View Connection Server host. The ADSI Edit utility is installed with View
Connection Server.
When you change View LDAP on a View Connection Server instance, the change is propagated to all replicated
View Connection Server instances.
