Once the new role is assigned to a SAP user, specify the name of this user against SAPUser.Ĭonfirm the password by retyping it here. The procedure for the same has been provided in Creating a New User Role for Monitoring and Assigning it to a SAP User. Ideally, you will have to create a new user role on the SAP ABAP instance for this purpose, associate the above-mentioned authorization objects with that role, and assign the new role to an existing SAP user. Typically, to connect to a SAP ABAP instance and run tests, the eG agent requires the permissions of a SAP user who has been assigned with certain authorization objects S_BGRFC, S_RFC, S_RFC_ADM, S_RFCACL, S_TCODE, S_ADMI_FCD, S_TABU_DIS, S_TABU_NAM, S_USER_GRP, S_XMI_PROD, S_TOOLS_EX, S_APPL_LOG, S_RZL_ADM. To know how to determine the client ID to use, follow the instructions provided in Determining the Client ID/Name for the eG Agent to Connect to the SAP ABAP Instance. Specify the ID of the client system as what the eG agent will be connecting to the SAP ABAP instance. Host name of the server for which the test is to be configured.Įnter the port to which the specified host listens. Configurable parameters for the test Parameter Outputs of the test : One set of results for every qRFC queue type on the server being monitored an additional All descriptor is also supported, which aggregates metrics across queue types. In the process, the test turns the spotlight on those queues that may be responsible for unexpected breaks or prolonged delays (if any) in inter-system communication, and also reveals what could be causing such queues to perform poorly.Īgent deploying the test : An internal/remote agent For each type (inbound and outbound) of queue, this test reports the number of queues that are experiencing errors currently and the count of queues that took too long to complete. This can be achieved using the QRFC Queues test. To be able to promptly capture deficiencies in queue execution and rapidly isolate the reasons for the same, administrators should closely monitor the inbound and outbound qRFC queues. Two systems can engage in smooth, uninterrupted communication using qRFC only if the outbound and inbound queues operate in an error-free manner. This prevents a server from being blocked by a client. The inbound queue only processes as many function modules as the system resources in the target system (server) at that time allow. This guarantees the sequence and efficiently controls the resources in the client system and server system. In other words, if a qRFC with inbound queue exists, it means that an outbound queue also exists in the sender system. In the qRFC with inbound queue scenario on the other hand, for an outbound queue in the sender system (client), there is also an inbound queue in the target system (server). (Note: the programming code of the server system must not be changed. The called system (server) has no knowledge of the outbound queue in the sender system (client), meaning that in this scenario, every SAP system can also communicate with a non-SAP system. This means that function modules which depend on each other (such as update and then change) are put into the outbound queue of the sender system, and are guaranteed to be sent to the target system one after each other and one time only. qRFC with inbound queue (and outbound queue)įigure 2.21 depicts both these communication scenarios:Īs you can see, in a qRFC with an outbound queue, the sender system uses an outbound queue to serialize the data that is being sent.In qRFC, the following communication scenarios are possible: The sender system is called the client system, while the target system corresponds to the server system. While the actual sending process is done by the tRFC, inbound and outbound queues are added to the tRFC, thus resulting in a qRFC (queued Remote Function Call). QRFC performs a serialization of tRFC (Transactional RFC) using wait queues. These features were further enhanced through the queued RFC with inbound/outbound queue. Whereas the first version of the RFC, the synchronous RFC, (sRFC) required both systems involved to be active in order to produce a synchronous communication, the subsequent generations of RFC had a greater range of features at their disposal (such as serialization, guarantee for one-time-only execution, and that the receiver system does not have to be available). RFCs can be used to start applications in remote systems, and to execute particular functions. An interface that can be used for dealing with this task is the Remote Function Call (RFC). This communication may take place within an SAP system, with another SAP system, or with an application from a remote external system. All types of applications are instructed to communicate with other applications.
