Hi Ravi,

WebApplications are developed on pooling concepts which stores the connection objects.If any application object is not being used since long time ,using the expiration time option we can destroye the object and it can be alloted to another request.In this way End user performance can be improved and load on the server can be reduced.

Hi ravi,

At design time, you can declare several configuration properties for your Web Dynpro application. Examples of this are the specification of an expiration time for the application (ExpirationTime) or the definition of the HTML page to be used as the logoff page (LogoffURL). The configuration property Authentication, which describes the Boolean value for the use of the authentication, is also included in the configuration options.

You set the properties of the application configuration in the SAP NetWeaver Developer Studio. For some properties, the values of the Web Dynpro system configuration are adopted if you have not already set them explicitly in the application configuration. For example, the value of the DefaultExpirationTime parameter of the Web Dynpro system configuration is used if you have not assigned a value to the ExpirationTime property of the application configuration.

The configuration property ExpirationTime describes the lifetime in seconds of a Web Dynpro application on the server before the Web application is terminated by the server. The value that is assigned to the DefaultExpirationTime parameter in the system configuration is used as the default value.

ExpirationTime Specifies the lifetime in seconds of a Web application on the server before the Web application is terminated by the server.

The value of the DefaultExpirationTime parameter of the system configuration is used as the default value.

HI Ravi Kiran,

The expiration time in Web Dynpro Java, is used for various reasons viz:

Security: If a user, opens a sensitive service and keeps the system unattended, the service will automatically expire after the assigned expiration time.

System Performance: To optimize the load on the server, expiration time is used. Thus, the load on engine due to unattended but opened services will reduce.

I hope this would help you. If you need any further assistance, I'll be pleased to help you.

Cheers!!!

Hi,

the expiration time is set in the server that, but you can set in the webdynpro application as part of application properties, the default time for your application is 1 hour, so you can chage it Was JAVA admin tools also, when the application is cross that time the application is stopped and the removed from server. so that application is not able to run in the portal server,

normally the if the memory is full or server is slow, the administrtor will do the cleanup that is remove all un used application from the server to improve the performance of the server,
