11 What are LeaseTime, SponsorshipTime, RenewonCallTime and LeaseManagerPollTime?
Ans:
In normal .NET environment objects garbage collector manages lifetime. However, in remoting environment remote clients can access objects, which are out of control of garbage collector. Garbage collector boundary is limited to a single PC on which framework is running; any remote client across physical PC is out of control of GC (Garbage Collector).
This constraint of garbage collector leads to a new way of handling lifetime for remoting objects, by using concept called as “LeaseTime”. Every server side object is assigned by default a “LeaseTime” of five minutes. This lease time is decreased at certain intervals. Again, for every method call a default of two minutes is assigned. When i say method call means every call made from client. This is called as “RenewalOnCallTime”.
Let’s put the whole thing in equation to make the concept more clear.
Total Remoting object life time = LeaseTime + (Number of method calls) X (RenewalTime).
Then default Remote Object Life Time = 5 + (1) X 2 = 10 minutes (Everything is in minutes)
When total object lifetime is reduced to zero, then it queries the sponsor that should the object be destroyed. Sponsor is an object, which decides should object Lifetime be renewed. So it queries any registered sponsors with the object, if does not find any then the object is marked for garbage collection. After this garbage, collection has whole control on the object lifetime. If we do not foresee how long a object will be needed specify the “Sponsorship Timeout” value. Sponsorship Timeout is time unit a call to a sponsor is timed out.
“LeaseManagerPollTime” defines the time the sponsor has to return a lease time extension.
13 Which config file has all the supported channels/protocol?
14 How can you specify remoting parameters using Config files?
15 Can Non-Default constructors be used with Single Call SAO?
16 How can we call methods in remoting asynchronously?

22 What is DISCO?
23 What is WSDL?
24 What the different phase/steps of acquiring a proxy object in Web service?
25 What the different phase/steps of acquiring a proxy object in Web service?
26 What is file extension of Web services?
27 Which attribute is used in order that the method can be used as WebService?
28 What are the steps to create a web service and consume it?
29 Do webservice have state?
