If one process has to shut down because of some error or exception, the other processes and their clients are not affected. The other new application lifetime management service is recycling. Application recycling is used to increase overall application robustness and availability by compensating for code defects. For example, one of the most common defects is a memory leak. Not all products have the necessary quality assurance resources or commitment during development and, as a result, memory leaks can occur even in released products.
Even a very small memory leak can have a devastating effect over a long period of time. For example, imagine a system with an "insignificant" memory leak of only 10 bytes per method call.
A modern system that processes in excess of method calls per second will, after one day, leak MB of memory. The process hosting the application will consume this amount of memory, which will severely hamper performance and availability, due to the additional page faults and memory allocation penalties.
This technique is called application recycling. A value of zero no limit is the default value. A value of zero no lifetime limit is the default value. Note that the lifetime limit semantics are different from the idle time management option on the application Advanced tab. The Server Process Shutdown value on the Advanced tab specifies the length of idle time not servicing clients after which the application should be shut down.
The lifetime value specifies the number of minutes before application shutdown, irrespective of the work in progress inside the process. The number of calls is defined as the combined number of calls made on all the objects in the application. The default value is set to zero no limit. You can also request application recycling after a certain number of activations.
You specify activation limit in the Activation Limit edit box, and again, the default value is set to zero no limit. The default expiration timeout is 15 minutes. To configure memory and time-bound recycling, use the RecycleMemoryLimit and RecycleLifetimeLimit named properties of the application's Catalog object.
To configure the expiration timeout, use the RecycleExpirationTimeout named property. When you want to configure the call or activation limits programmatically, set the RecycleCallLimit or RecycleActivationLimit properties.
Figure 10 shows how to programmatically set a recycling limit. The code implements the SetRecycleByActivations helper function that sets a limit of activations for recycling a specified app. For debug and analysis purposes, it is sometimes useful to get a complete memory dump of an application, especially at the time of a crash.
You can use a utility such as WinDbg to view and analyze this image. You can specify a location for the image dump and the number of images to store there.
When the maximum number of images is reached, a new dump image overwrites the oldest one. Figure 11 Application Dump You can generate a dump file in a number of ways. An application's fault in this context is when an exception is thrown. The second way is to select Dump from a running application's context menu see Figure 6.
When you use the DumpProcess method, you have to provide the dump directory and file name, and you cannot rely on the configured values. Requesting a dump either by calling DumpProcess or selecting Dump from the context menu on a running application is nonintrusive—the process can continue to run, and is only frozen temporarily for the duration of the dump. Instead, this article provides a simplified overview of the partition concept. Partitions provide an economic way of presenting each user be it a logged-on user or a call coming in across the network with its own set of applications and components.
Partitions are usually configured in Active Directory. If you want to install the same component same CLSID in multiple applications, you have to do so on multiple machines. A given machine can contain multiple partitions, and each partition can have its own set of applications and components.
You assign users to partitions in Active Directory. If the base partition does not contain the component, then the creation fails, even if the component is part of another partition. For example, consider the partition layout in Figure If a user associated with partition A tries to create only the component with CLSID1, then that component is created from partition A, and the configuration settings of App1 in partition A are applied, as well as any component-level configuration.
However, if the user tries to create the component with CLSID3, then the component from the base partition is created, and the base partition settings are applied. Figure 12 Application Partitioning Figure 12 shows that a given CLSID can belong to more than one partition, but a given partition can only have one copy of the component. Different partitions can contain applications with the same name.
The different partitions inherit the base partition's applications and components, but they can override them, remove them, add new components, and change their settings.
Application partitions provide an easier way for managing activations and isolating applications between partitions. Each partition can be managed independently of the other, and you can even install different versions of the same component in different partitions, thus tailoring a particular compatibility solution.
The context object supports a new interface called IObjectContextInfo2 that derives from IObjectContextInfo, which allows you to get information about the partition and the application that the object is part of. Clients can request the creation of an object in a particular partition using a special moniker. The ICOMAdminCatalog2 interface provides you with numerous methods for managing partitions, including copying an application from one partition to another, copying and moving a component from one partition to another, getting the base application partition ID, and getting the current partition ID.
This is called aliasing a component. Aliasing is quite often a useful feature—you develop a piece of business logic and assign more than one set of configuration parameters to it by aliasing it as much as you like. The component's client can now decide which configuration setting and business logic implementation to instantiate by creating a particular CLSID. This brings up the Alias Component dialog see Figure The dialog lets you select a destination application for the new component.
Because you are assigning a new CLSID to the component, you can even copy it back to its current application. Old prog - ID , as you can see in Figure You can provide your own values for these if you like. Initially, the new component has the exact same configuration setting as the original one.
