5 Configuring Your Oracle Network

This chapter describes how to configure the network.

5.1 Configuring the Oracle Network for the Gateway

The instructions in this section will show you how to configure the network if the gateway is utilizing the SNA or TCP/IP communication protocol.

The gateway must be defined to the Oracle Net Listener, and a service name must be defined for accessing the gateway. To do this, perform the following steps:

  1. Add an entry for the gateway to the listener.ora file:

  1. Add a service name for the gateway to the tnsnames.ora file on the system where your Oracle database is located. The service name is specified in the USING parameter of the database link defined for accessing the gateway from the Oracle database. For example, if you are using the IPC protocol adapter and your gateway sid is PGA, then add the following entry to tnsnames.ora:

    pgaipc= 
            (DESCRIPTION = 
                    (ADDRESS = (PROTOCOL = ipc) (KEY=key))
                    (CONNECT_DATA = (SID=PGA)) 
                    (HS=) 
            ) 
    

    In this example, key is the IPC key defined in the listener.ora file for the IPC protocol. You can use the IPC protocol only if the Oracle database and the gateway are on the same system.

    If you are using the TCP/IP protocol adapter, and if your gateway sid is PGA, then add the following entry to tnsnames.ora:

    pgatcp= 
            (DESCRIPTION = 
                  (ADDRESS = (PROTOCOL= TCP)(Host= gateway)(Port= port)) 
                    (CONNECT_DATA = (SID=PGA)) 
                    (HS=) 
            ) 
    

    In this example, port is the TCP port defined in the listener.ora file for the TCP protocol, and gateway is the TCP/IP host name of the system where the gateway is located.

    Note:

    For the following cases:
    • If your gateway and Oracle database are not on the same system,

    • If the gateway and the Oracle database are on the same system but the Oracle database Listener is different than the gateway listener

    You must define the Oracle database to PGAU by adding a service name to tnsnames.ora on the system where your gateway is located. For example:

    ora_server =
       (DESCRIPTION=
         (ADDRESS = 
           (PROTOCOL= TCP) 
           (PORT= port) 
           (HOST= ora_srv)
          )
          (CONNECT_DATA= (SID= ora_server))
       )
    

    In this example:

    • port is the TCP port defined in the Oracle database listener.ora for the TCP protocol;

    • ora_srv is the TCP/IP host name of the system where the Oracle database is located; and

    • ora_server is the SID of the Oracle database.

    Ensure that you start the defined listener(s).

Proceed with Configuring the Communication Package for the Gateway

If your communication protocol is SNA, you must now configure the SNA communication package profiles for APPC connections.

Configure the profiles to define LU6.2 conversations with the OLTP. Refer to the appropriate chapter from the following list to read about the SNA communication package or the TCP/IP package for your platform.

In addition, if your communication protocol is SNA, refer to "Sample listener.ora file for a Gateway Using SNA" and "Sample tnsnames.ora file for a Gateway Using SNA" in Appendix A.

If your communication protocol is TCP/IP, refer to "Sample listener.ora File for a Gateway Using TCP/IP" and "Sample tnsnames.ora File for a Gateway Using TCP/IP" in Appendix B.
