Configure Output Manager with SAP in a high availability environment

Output Manager requires additional configuration when receiving print jobs from SAP through a load balancer.

Note: High availability setup is only available for input services when SAP is configured for use with command line.

To enable print job submissions through a load balancer, each Input Service must be configured with a mapping. The mapping connects the source name specified in the SAP configuration to the NetWeaver source name in Output Manager. When the SAP print job submission request is received by the load balancer, and routed to one of the available Input Services, the source name specified by the request does not exist. In this case, the Input Service checks its configuration mapping to determine the NetWeaver source based on the source specified in the request.

Note: Each source must have unique name across all Input Services.

Output Manager requires additional configuration when receiving query requests from SAP, and print jobs are submitted through a load balancer.

In addition, the DBM Service must be configured to answer query request from SAP. SAP queries Output Manager for the status of a device and the status of print jobs. This request uses the same source as the job submission request. Since that source does not exist in Output Manager but a mapping is configured on each Input Service, all sources mapped to the SAP source must be configured in the DBM. Each DBM service in a high availability environment must have the same configuration.

  1. Configure the Input Service for use behind a load balancer.

    Edit the NSiOutputManagerInputService.exe.config file in the OutputManager/Services/Input folder.

    Add the <add key="HA_SOURCE_MAPPING" value="SAP_PRINT:SAP_PRINT1"> line to the <appSetting> section.

    SAP_PRINT

    The SAP printer (OM source) name

    SAP_PRINT1
    The OM source name for this Input Service
    Note: If there is more than one SAP, use comma to separate the pairs, for example: SAP_PRINT:SAP_PRINT1 , ANOTHER_SAP_PRINT:ANOTHER_SAP_PRINT1
  2. Configuring the DBM Service when the Input Service is configured.

    Edit the NSiOutputManagerDbmService.exe.config file in the OutputManager/Services/DBM folder.

    Add the <add key="HA_SOURCE_MAPPING" value="SAP_PRINT:SAP_PRINT1|SAP_PRINT2"> line to the <appSetting> section.

    SAP_PRINT

    The SAP printer (OM source) name

    SAP_PRINT1

    The first OM source name for this Input Service

    SAP_PRINT2

    The second OM source name for this Input Service

    Note: The OM source name is separated by a pipe (|). If there is more than one SAP, use comma to separate the printers, for example: SAP_PRINT:SAP_PRINT1|SAP_PRINT2 , ANOTHER_SAP_PRINT:ANOTHER_SAP_PRINT1|ANOTHER_SAP_PRINT2
