Configuring Systems with Several Application ServersLocate this document in the navigation structure

To prevent synchronization issues in multi-server systems, you can define that all requests from the SAP Fiori launchpad designer are sent to the same application server.

Context

In the SAP Fiori launchpad designer, some data is stored in the application memory specific to the application server. The synchronization of this data using the various application servers may require up to 60 seconds. An error occurs if data is written on one server and read on a different server before the synchronization is complete. In that case, the system displays incorrect data after you change catalogs or groups. As a result, for example, the title of a catalog that was created previously is missing after you restart the launchpad designer.

To prevent this issue, you can specify a logon group for HTTP load balancing to define that all requests from the SAP Fiori launchpad designer are sent to the same application server.

Procedure

  1. Use transaction SMLG (CCMS: Maintain Logon Groups) to configure a logon group that is assigned to only one application server.
    For more information, go to http://help.sap.com/ and search for Defining Service Data.
  2. Define load balancing for services.
    1. Call transaction SICF (Maintain Services).
    2. Navigate to the service path /sap/opu/odata/ui2/page_builder_cust and switch to change mode.
    3. On the Service Data tab, mark the Do Not Include Inherited Settings checkbox.
    4. In the Load Balancing field, enter the logon group you configured in step 1.
    5. Save your changes.
    6. Perform the last 4 steps for the service /sap/opu/odata/ui2/page_builder_conf.
    For more information on the ICF configuration, go to http://help.sap.com/ and search for HTTP Load Distribution.
  3. Implement SAP Note 1711354 Information published on SAP site.

Results

All requests from the SAP Fiori launchpad designer are sent to the same application server and the synchronization problems no longer occur. For the SAP Fiori launchpad, however, the system still takes all load balancing settings into account as before. In this case, it uses the service /sap/opu/odata/ui2/page_builder_pers.
