Default Parameters for AsAbapRfcDnTest
By closely monitoring RFC destinations in the target environment, administrators can figure out the RFC destinations that are not reachable for a long duration. The detailed diagnosis helps administrators figure out the reason for why the RFC destination is not reachable.
This page depicts the default parameters that need to be configured for the AsAbapRfcDnTest test.
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 the following authorization objects: S_RFC, S_TABU_DIS, S_XMI_PROD, S_TOOLS_EX, S_RZL_ADM. 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. To know the procedure for the same, click here. Once the new role is assigned to a SAP user, specify the name of this user against SAPUSER.
The SYSNO parameter appears only if the USE SAPCONTROL flag is set to No - i.e., if the test uses SAPJCO to collect measures. An indicator of the TCP/IP port at which the SAP server listens. For example, for a server that listens at port 3200, the SYSNO will be ‘00’. Similarly, if the SAP server port is 3201, the SYSNO will have to be specified as ‘01’. Therefore, in the SYSNO text box specify the system number of the SAP server with which the specified client communicates. To know the system number for the ABAP server being monitored, click here.
The ROUTER parameter appears only if the USE SAPCONTROL flag is set to No - i.e., if the test uses SAPJCO to collect measures. If the SAP client with the specified CLIENTNAME exists in a network external to the SAP server, then a router will be used to enable the server-client communication. In such a case, specify the router string of the router in the ROUTER text box. If both the client and the server exist in the same network, then specify ‘none’ against the ROUTER text box. To know what is the SAP Router string for the ABAP server being monitored, click here.
The eG agent uses the SAP JCO library to connect to the SAP ABAP system and pull out metrics. To enable the eG agent to make this connection and query the metrics, you need to specify the version of the SAP JCO library that the agent needs to use. For instance, to instruct the eG agent to use JCO v2.1.19, it would suffice if you specify the ‘major version number’ alone against JCO VERSION - in the case of this example, this will be 2.x. Note that if you have downloaded the SAP JCO CONNECTOR files for SAP JCO version 3 from the SAP market place, then the JCO Version configuration should be 3.x.
By default, while administrators configure an RFC destination, they indicate the system connection type in the Connection Type field. When Type 3 is specified as the connection type, it indicates RFC connections to ABAP systems. By default, these Type 3 connection types are monitored by eG Enterprise and therefore, the MONITOR ABAP CONNECTIONS flag is set to Yes, by default. If administrators do not wish to monitor Type 3 connection types, then, they can set this flag to No.
When Type I is specified as the connection type, it indicates an RFC connection between the ABAP systems connected to the same database as the current system. By default, these Type I connection types are monitored by eG Enterprise and therefore, the MONITOR INTERNAL CONNECTIONS flag is set to Yes, by default. If administrators do not wish to monitor Type I connection types, then, they can set this flag to No.
When Type L is specified as the connection type, it indicates an RFC connection to a physical destination. By default, these Type L connection types are monitored by eG Enterprise and therefore, the MONITOR LOGICAL CONNECTIONS flag is set to Yes, by default. If administrators do not wish to monitor Type L connection types, then, they can set this flag to No.
When Type S is specified as the connection type, it indicates an RFC connection that uses IBM's System Network Architecture (SNA) as its destination. By default, these Type L connection types are monitored by eG Enterprise and therefore, the MONITOR SNA/CPI-C CONNECTIONS flag is set to Yes, by default. If administrators do not wish to monitor Type S connection types, then, they can set this flag to No.
Type T destinations are connections to external programs that use the RFC library to receive RFCs. By default, these Type T connection types are monitored by eG Enterprise and therefore, the MONITOR TCPIP CONNECTIONS flag is set to Yes, by default. If administrators do not wish to monitor Type T connection types, then, they can set this flag to No.
Type X entries indicate systems where device drivers in ABAP have been specially installed. By default, these Type X connection types are monitored by eG Enterprise and therefore, the MONITOR ABAP DRIVER CONNECTIONS flag is set to Yes, by default. If administrators do not wish to monitor Type X connection types, then, they can set this flag to No.
The DD FREQUENCY parameter refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.
When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
