System.Runtime.Remoting.Lifetime.LifetimeServices Class

Summary

Controls the .NET remoting lifetime services.

C# Syntax:

public sealed class LifetimeServices

Distributed garbage collection is responsible for controlling the lifetimes of server applications, and for deleting when them when their lifetimes have expired. Traditionally, distributed garbage collection uses reference counts and pinging for control. This works well when there are a few clients per object, but does not work well when there are thousands of clients per each object. The lifetime service can assume the function of a traditional distributed garbage collector, and scales well when the number of clients increases.

The lifetime service associates a lease with each remotely activated object. When the lease expires, the object is removed.

LeaseTime	Read-write Gets or sets the initial lease time span for an AppDomain.
RenewOnCallTime	Read-write Gets or sets the amount of time by which the lease is extended every time a call comes in on the server object.
SponsorshipTimeout	Read-write Gets or sets the amount of time the lease manager waits for a sponsor to return with a lease renewal time.

Summary:

Default constructor. This constructor is called by derived class constructors to initialize state in this type.

C# Syntax:

public LifetimeServices();

Return to top

Summary

Gets or sets the time interval between each activation of the lease manager to clean up expired leases.

C# Syntax:

public static TimeSpan LeaseManagerPollTime {get; set;}

The current property defines the frequency at which the lease manager becomes active to clean up expired leases. For example, if LifetimeServices.LeaseManagerPollTime is set to 100 seconds, the lease list is inspected for cleanups and renewals every 100 seconds.

The default value of the LifetimeServices.LeaseManagerPollTime property is 10 seconds.

SecurityPermission for configuration of the remoting infrastructure. Associated enumeration: SecurityPermissionFlag.RemotingConfiguration.

Summary

Gets or sets the amount of time by which the lease is extended every time a call comes in on the server object.

Summary
