No object manager started (application stopped)

[Former Member]

Hello...

I'm new to Netwevaer, sorry if this has been posted before.

I'm trying to do the hands on from SAPTECHED in my SAP WAS 630 with a back end R/3 46C. I'm getting the following error message. Could you please help me in this regard.

No object manager started (application stopped)

Hi Karin,

What is an "Adaptive RFC"? Could you please pass some documentation on "Adaptive RFC"?

Hi A H Shiju ,

Do you have the course number available?

Thanks, Karin

Hi Karin...

Unfortunately I do not have the course number as of now.

The material name is Introduction to Web Dynpro. Version 1.3 . Author Chris Whealy. This one is for retreving a list of equipments from SAP system.

I think the material is developed for SAP WAS 630, but am using a 640 system. Will it make any difference? especially on BAPI->Model creation side?

Hello A H Shiju,

I am afraid you can not use the material for 6.40, especially the BAPI->Model... Since 6.40 we support Adaptive RFC only, the "older" RFC does not work that way, especially within the System Landscape Directory.

There are tutorials for the newer version on SDN available as well. Please go to Web Application Server, Downloads. Does this help?

Best regards, Karin

Hi again,

Please find the URL:

And here some information about the SLD:

Purpose

A modern computing environment consists of a number of hardware and software components that depend on each other with regard to installation, software updates, and demands on interfaces. The SAP System Landscape Directory (SLD) simplifies the administration of your system landscape.

The SLD is a server application that communicates with a client application by using the Hypertext Transfer Protocol (HTTP). The SLD server contains component information, a landscape description, and a name reservation, which are based on the standard Common Information Model (CIM). The CIM standard is a general schema for describing the elements in a system landscape. This standard is independent of any implementation.

Features

The component description provides information about all available SAP software modules. This includes version numbers, current patch level, and dependencies between landscape components. SAP makes this information available to its customers. You can download the current component description from SAP Service Marketplace, which then updates your local component description (see SAP Note 669669). It is also possible to add instances for third-party components to the component description.

The system landscape description represents the exact model of an actual system landscape. Together with the current component description, the system description provides information for various processes (the system administration and implementation, for example).

The example below shows a possible scenario that illustrates how the component and system landscape description functions.

Example

On the left-hand side of the following graphic is the master description for all existing SAP software modules. SAP maintains this information. The local component description on the right-hand side (client side) can be updated in accordance with the master description.

An installed mySAP.com component is registered in the System Landscape Directory. The component description contains information about the installed components. If, for example, a new Support Package is available for this component, SAP publishes this information using the master description. In this way, the customers receive all the latest information relevant for their system landscape promptly.

Hi Karin...

Thanks for your help, I really appreciate your effort. I was literally down for 2 days with this error. Thanks for

leading me to the cause.

Can I have a tutorial for WAS 640 which uses Adaptive RFCs to fetch data from Back End R/3s.

Thanks in Advance.

Hello A H Shiju,

The developer work on a How-to-guide, which makes the installation and configuration much easier. I'll let you know as soon as it is available.
