SAP RFC Server Group (RZ12)

RFC server groups help in parallel execution of asynchronous RFC calls. Transaction code RZ12 is used to set up new RFC server groups. These consist of pools of application servers, each with its own setup of RFC server group quotas. New RFC server groups are configured by using transaction RZ12 and pressing the F8 function key. The following illustration shows an RFC server group being assigned to a particular application server and the resource determination on that particular application server will be based on the allocated RFC server group quotas

57..What is an instance in SAP?

instance defines a group of resources such as

 memory

 work processes

 dispatcher

 gateway

58..What is an OLE in SAP?

OLE objects are objects that originate from various applications but can be used in the modeling environment. You can change the position and size of OLE objects.

If a model is opened that contains linked OLE objects, their link to the original object will be refreshed. For example, the link to a Wordpad document will be re-established. This assumes that the document path was not changed after insertion into the model. Whether refreshing is possible or not, linked OLE objects will always be displayed in the most recent refreshed state.

59..What is the interface control  shown on the PC in SAP?

Presentation Interface.

60..Explain   SAP  dispatcher and its functions?

The SAP Web dispatcher lies between the Internet and your SAP system. It is the entry point for HTTP(s) requests into your system, which consists of one or more SAP NetWeaver application servers. As a “software web switch”, the SAP Web dispatcher can reject or accept connections. When it accepts a connection, it balances the load to ensure an even distribution across the servers. The SAP Web Dispatcher therefore contributes to security and also balances the load in your SAP system.

of all SAP authorization components

The actual authorizations and profiles are stored in the SAP system as objects. With the roles, we can assign to any users which will be the user menu that is displayed after they log on to the SAP System. Roles also contain the authorizations with which users can access the transactions, reports, Web-based applications, and so on that are contained in the menu.

Maximum number of profiles that can be assigned to any user master record is 312.

The change flags are – C which means “User was created” and M which means “User was changed”.

The field PROFS is defined with a length of 3750 characters. Since the first two characters are intended for the change flag, 3748 characters remain for the list of the profile names per user. Because of the maximum length of 12 characters per profile name, this results in a maximum number of 312 profiles per user

The SAP work process is a component of the application server that executes an ABAP application.

Another way of thinking about this is that a client copy from production to a QA server    or from production to DEV server is really a client refresh
