Registering the Reserved Prefix for the Name
Reservation Service
Use
In this step, you set up the name server for registering the reserved prefix for the name reservation service.
Prerequisites
You work in the System Landscape Directory (SLD).
Procedure
Setup of the Name Server
The name server checks the uniqueness of the names and enables you to define name prefixes. The name server is a role of a SLD. The other role is the landscape server role. The setup of the name server takes place in the same way as the setup of the SLD server. Execute the following steps:
...
1. Activate the name server.
For the name server, the Object Server name must be a namespace reserved and declared as SAP NetWeaver Name Server on SAP Service Marketplace.
For testing purposes, the system ID is sufficient as an object server entry.
2. Import the SAP master component information.
3. Configure the SLD data suppliers.
4. Register the name server in the SLD of your landscape; this declares it as the name server for the development infrastructure. In this case, the role of the server must be Name Server.
Using an SLD
...
1. Go to the initial page of the SLD.
2. Choose Enable Name Reservation for NWDI.
Alternatively, you can proceed as described below and select both roles for the SLD.
Using Separate SLDs
1. Go to the initial page of the SLD.
2. Choose Landscapes.
The Create New Landscape page appears.
3. Select the landscape type NWDI System.
4. Enter a name for the landscape, for example NWDI.
5. Choose Create.
The new landscape is displayed.
6. Select the new landscape.
You see the details on the landscape.
7. Choose Systems and then choose Add System to Landscape.
8. Choose the hosted system type System Landscape Directory.
You see the installed SLD.
9. Choose OK.
10. Select the SLD.
The Details view appears.
11. Select the roles Landscape Server (and/) or Name Server.
12. Save your changes.
If you run the two features of SLD and name reservation service in one system in parallel, the server must have both roles of Landscape Server and Name Server.
The name server is now known to the NWDI and can be used there. Only now can you create valid development configurations.
Registering the Reserved Prefix for the Name Reservation Service
The NetWeaver namespace prefixes reserved on SAP Service Marketplace must be entered in the name server so that namespaces for development objects with those prefixes can be created in the name server. The name server supports different types of development object names. For details, read SAP Note 710315.
You can use a reserved namespace prefix for all object name types in parallel. Register the prefixes for different name categories as follows:
● By convention: <reserved-prefix>
Enter the SAP NetWeaver namespace prefix reserved on SAP Service Marketplace here (without any slashes).
● Design Time Package: Follows the syntax of the programming language. For instance, Java package names use reversed Internet domain names like com.company.project.*.
● Development Component: <vendor>/<reserved-prefix>*, whereas the slash / is used as a separator of the name segments.
To register a prefix, proceed as follows:
...
...
1. On the home page of the name server (use Home to access it), choose Development → Name Reservation → Define Namespace Prefix.
2. On the Define Namespace Prefix page, specify the name category and the namespace prefix and then choose Create.
3. For this tutorial, reserve only the name category Development Component Name. Specify the following entry: example.org/appl
