Gateway Software for the Integration of the HOB PC/Host Connectivity Products into the Internet

PC/Host Connectivity via TCP/IP:

The Gateway IBIPGW03

For HOBLink 3270, HOBLink J-Term and all TN3270-capable Emulations there is a new gateway "IBIPGW03". This gateway allows PCs to TCP/IP access to mainframes in an SNA net.

The advantages:

The PCs don’t have to be accessed to the SNA net. The connection can be done via a TCP/IP net, e.g. the internet.
No TCP/IP is needed on the host.

How it works:

Das Gateway IBIPGW03 has to be installed on an NT-Server. The communication between PC and NT Server is made over the TN3270 protocoll.

On the NT server a subsystem has to be installed, which provides the data over APPC for the SNA net. To do this Microsoft SNA-Server or IBM eNetwork Communications Server can be used. The communication with the host is performed over the LUA interface.

If HOBCOM is installed on the host, the HOB Y protocoll can be used for the communication. This protocoll provides some additional advantages, e.g. encryption and compression of the data.

Database Access via TCP/IP

The Gateway IBIPGW04

HOB offers a new gateway, "IBIPGW04". This gateway enables PCs to access via TCP/IP to DB2 database systems without using TCP/IP on the host site.

The advantages:

The PCs needn’t be connected to the SNA net. The connection can be done over a TCP/IP net, e.g. via the internet.
No TCP/IP is necessary on the host. Thus, the database systems DB2/VM, DB2/VSE and DB2/400, which don’t allow DRDA access via TCP/IP, are available from the PC via TCP/IP. Further DB2/2, DB2/Windows NT, DB2/6000 and DB2/MVS databases can be accessed this way.

How IBIPGW04 works:

The gateway IBIPGW04 has to be installed on Windows 32 bit system. On this server there has to be a sub-system , too, which provides the data via APPC for the SNA net. Possible sub-systems are HOBLink SNA Stack (HOBAPPC), Microsoft SNA Server, Novell Netware for SAA or IBM eNetwork Communications Server. The communication with the host is performed over the LU 6.2 interface.
