If your CICS® bundle
project is part of a CICS application,
you can define one or more application entry points in the bundle
manifest. An application entry point identifies a resource that is
an access point to an application.
About this task
You use the Create Application Entry Point wizard
in the CICS Explorer to create an application entry point. An application
entry point can apply to the whole application or a specific application
operation; for example, you can declare application entry points for
create, read, update and delete operations. Each application entry
point is declared on a resource and names an operation. You can define
application entry points only on a subset of CICS resources.
The resource for the
application entry point does not have to be defined in the same CICS bundle project as the application
entry point. CICS adds the
application operation to the specified resource when the application
is installed.
When a task that does not have an application
context calls a resource that has an application entry point, CICS creates an application context
that becomes associated with the task, and with any subsequent programs
that it calls and tasks that it starts. The application context identifies
the platform, the application, the application version, and the operation.
You can use the application context data for the following purposes:
- Monitoring and measuring how much resource an application or a
particular application operation is using across CICS regions and multiple tasks.
- Applying a policy to tasks that are part of an application, to
define threshold conditions to manage the behavior of the tasks.
- Using the information with the transaction tracking capability
in the CICS Explorer® to
quickly identify and diagnose application-related problems.
Results
You have created an application entry point for an application.
When the application is deployed, the operation name is added to the
specified resource, and application context data is produced for tasks
that use the resource.
