Preparing System Landscape Data Router

This means you plan to share managed systems among multiple Focused Run systems, but you do not need to forward Data Supplier payloads to SAP Solution Manager, SAP NetWeaver PI or other components. This SLDR is used to forward the Data Supplier payloads (including Outside Discovery) to the reverse proxies or load balancers of the relevant Focused Run systems.

Note: SLDR shall be discovered first by Focused Run following the Preparing Outside Discovery page, and then, configured following the below Configure SLDR Section.

-If case B applies: One SLDR is required (per relevant customer network).

This means you plan to share managed systems and corresponding payloads among one Focused Run system, and, in parallel, you plan to forward Data Supplier payloads to SAP Solution Manager AP, SAP NetWeaver PI or other components. This SLDR is used to forward the Data Supplier payloads (excluding Discovery) to the reverse proxies or load balancers of the relevant Focused Run systems and SAP Solution Manager. Focused Run Outside Discovery Payload Shall not be send to the SAP Solution Manager SLD, therefore it must be send directly to Focused Run (LMDB).

Note: SLDR shall be discovered first by Focused Run following the Preparing Outside Discovery page, and then, configured following the below Configure SLDR Section.

 

-If case C applies: Two SLDRs are required (per relevant customer network). This is a combination of case A and B. 

This means you plan to share managed systems and corresponding payloads among multiple Focused Run systems, and, in parallel, you plan to forward Data Supplier payloads to SAP Solution Manager AP, SAP NetWeaver PI or other components. Focused Run Outside Discovery Payload Shall not be send to the SAP Solution Manager SLD, therefore it must be send directly to Focused Run (LMDB).

Note: SLDR shall be discovered first by Focused Run following the Preparing Outside Discovery page, and then, configured following the below Configure SLDR Section.

2 - Configure SLDR

The System Landscape Data Router (SLDR) is a component enabled on the Simple Diagnostics Agent (SDA), running on the Customer Management Server in the relevant Customer Networks.

The SLDR can be useful in the following scenarios:

Case A) You plan or you operate several Focused Run.
Case B) You plan or you operate SAP Solution Manager in parallel with Focused Run.
Case C) You plan or you operate SAP Solution Manager in parallel with several Focused Run.

For a detailed discussion on the different scenarios, please check the page for SLD DS Payload Distribution.

Note: The SLDR relevant configuration is stored in the file: /usr/sap/hostctrl/SMDAgent/default/configuration/t-connector/<Managing SID>/custom.properties

Remind that the Simple Diagnostics Agent (SDA) is remotely deployed onto a SAP Host Agent, only if the host Outside Discovery were executed successfully. 

See the Preparing Outside Discovery page.

To configure the SLDR start the Infrastructure Administration / Agent Administration, within the Launchpad:

  • Search and select the SLDR host
  • In drop down Agent Action, choose the value Open SLDR Configuration
  • Press Go
  • In the displayed SLDR Configuration pop-up provide:
    • In the SLDR Activation section
      Select This Host is an SLDR
      Select Active
    • It is possible to define multiple inbound ports at the SLDR. In the inbound connections section press Add and specify how to access the SLDR

      • “HTTP + Basic Authentication”
        • Define the desired SLDR HTTP Port number
        • Select “HTTP” for secure communication
        • Select “Basic Authentication”
        • Provide the SLDR User name: FRN_SLDS_<CID> (also known as SLD_DS_<CID>) and enter a Password. This user is created on the SLDR once you completed the wizard
           
      • “HTTPS + Basic Authentication”
        • Define the desired SLDR HTTP Port number
        • Select “HTTPS” for secure communication
        • Select “Basic Authentication”
        • Provide the SLDR User name: FRN_SLDS_<CID> (also known as SLD_DS_<CID>) and enter a Password. This user is created on the SLDR once you completed the wizard

      • “HTTPS + Certificate Based Authentication"
        • Define the desired SLDR HTTP Port number
        • Select “HTTPS” for secure communication
        • Select “Certificate-Based Authentication”
        • Provide the complete certificate subject name as SLDR User name. No password is required
           
    • In the outbound connections section
      Press Add and specify how to access the Focused Run system :

Case A:

- <SID> of one or Multiple Focused Run systems.
- HTTP <URL> of relevant reverse proxy or load balancer of one or Multiple Focused Run systems.
- <USER> created during the Customer Network preparation: FRN_LDSR_<CID>.

Case B:

 - <SID>
  of an Focused Run system OR the <SID>.
  of SAP Solution Manager Central Classical SLD.
 - <URL>
  of relevant reverse proxy / load balancer of the Focused Run system .
  of SAP Solution Manager Central Classical SLD.
 - <USER>
  created during the Customer Network preparation: FRN_LDSR_<CID>.
  of SAP Solution Manager Central Classical SLD.

Case C:

- <SID>
  of one or Multiple FRUN Systems.
  of SAP Solution Manager Central Classical SLD.
  of the Second SLDR
- HTTP <URL>
  of relevant reverse proxy / load balancer of the FRUN system.
  of SAP Solution Manager Central Classical SLD.
- <USER>
  created during the Customer Network preparation: FRN_LDSR_<CID>.
  of SAP Solution Manager Central Classical SLD.
  of the second SLDR: FRN_SLDS_<CID>.

Select the primary Focused RUN if several Focused Run are declared. This setting ensures that the return of the Focused RUN will be propagated to the data supplier.

Note: It is recommended to test the specified Inbound and Outbound URLs, using a Web Browser (if possible). Refer to the Security Guide, chapter System Landscape Data Router Configuration, for additional details about the authentication.

1 - Determine amount of required SLDR

The System Landscape Data Router (SLDR) is a component enabled on the SDA, running on the Customer Management Server in the relevant Customer Networks.

What is your situation, in regards to the managed systems being now prepared in the context of Focused Run?

  • A - You plan or you operate several FRUN.
  • B - You plan or you operate SAP Solution Manager in parallel with Focused Run.
  • C - You plan or you operate SAP Solution Manager in parallel with several Focused Run.

 

Depending on your situation:

-If none of the above use cases applies: No SLDR is required.

You can skip this chapter, as the Data Suppliers, of the managed objects (including Outside Discovery), can be directly connected to LMDB through reverse proxy of the Focused Run System.

-If case A applies: One SLDR is required (per relevant customer network).
