The SAP Network Server service is required when using the Extractor Connector. The service supports parallel loads and allows the use of Extractors containing many fields (field character sum greater that 1000). The service files are:
These files are included in the connector installation package and placed in the following Program Files directory when the connector is installed:
C:\Program Files\Common Files\QlikTech\Custom Data\QvSAPConnector
The Network Server must itself be installed to make the service available. The service is only needed for the Extractor Connector.
Do the following:
Start a new command prompt using Run as administrator and enter the path to the folder of SrvService_Console.bat.
At the command prompt, start SrvService_Console.bat.
Install the service by selecting option 2: Install Server Service.
Once installed, select option 3: Start Service.
To provide the highest level of security, the Network Server must be installed on the same system as the SAP Connector. The Network Server service uses localhost access by default to increase security for data transfer between the service and the Extractor Connector.
The service can be installed on a separate system from the connector, but in that case, the data transferred between the Network Server and the connector is not secure. Client systems that are not hosting the Network Server service cannot connect to the service by localhost. Those client systems must specify the IP address of the system running the service when connecting with the Extractor Connector.
Also, the system running the Network Server must add the client IP address of any system that connects to the service to its settings.config file. The settings.config file is located in:
If multiple users connect to the SAP system from separate machines, only one of those machines can host the Network Server. In that case, only connections made from the system running the Network Server can use localhost. Connections made from the other machines will not be as secure.
The Network Server communicates with the SAP system on a separate, secure connection. That connection is secure whether the service is installed on the same system as the connector or on a separate system.
After installing the Network Server, see SAP Connector configuration for information on the configuration of connectors.
