Setting Up Open Data Services

In the following example, the gateway application sets up Open Data Services.

1. Specify a server process, define the configuration structure for the server, define a pointer for the server's Windows NT Registry key name, and define a pointer for the server name at the remote data source:

   SRV_SERVER *server;                  // The service process        
   SRV_CONFIG *config;                  // The configuration structure
   DBCHAR *RegistryName = "Gateway";    // Registry lookup name       
   DBCHAR *SrvrName = "";               // Default remote server name 
   

2. Read the command-line argument to get the name of the remote server to use and send the remote server name to the gateway's DLL:

   // Read any command-line arguments. 
   getargs(argc, argv);
   
   // Send the name retrieved to the gateway's DLL module. 
   set_remote_server_name(SrvrName);
   

3. Allocate a configuration structure, initialize it to allow 20 client connections, and define the log file as GATEWAY.LOG:

   // Allocate a configuration structure that is used to initialize 
   // the Open Data Services server application.                    
   config = srv_config_alloc();
   
   // Allow 20 connections at a time.  
   srv_config(config, (DBINT)SRV_CONNECTIONS, "20", SRV_NULLTERM);
   
   // Set the log file.     
   srv_config(config, (DBINT)SRV_LOGFILE, "gateway.log", SRV_NULLTERM);
