Gateway Service

[Former Member]

Hi,

My portal URL is <host_name>:50100/irj

Even the directory struct is: C:\usr\sap\J2E\JC01...

So I assume my system number is 01.

I am trying to create an RFC Connection from Portal to my ABAP stack.

It works well if I use sapgw00 as the gateway service.

Systems file (C:\WINDOWS\system32\drivers\etc) has the following entries:

sapgw00 3300/tcp

sapgw01 3301/tcp # SAP System Gateway Port

Now if I use sapgw01 as the gateway service. It doesnt work. It gives error message error creating bundle..

In the error log it says:

ERROR partner '<hostname>:sapgw01' not reached

Thanks in advance,

CD

Is '00' the system number for your ABAP stack? Then you might as well use that as the gateway for the RFC connection.

Yes the system number for ABAP stack is 00.

Can you help me understand which one shall I use and why?

Here is a great post that discusses this in a bit more detail: [What is the gateway used for?|https://forums.sdn.sap.com/click.jspa?searchID=11281658&messageID=4990837]

Specifically, the gateway service is the conduit for communications to other systems (one being the java stack, another would be Trex, and still another could be a mainframe system).

Hope that helps.

Joe, that was helpful..

One last question...

So gateway service will always be for my target system right, in case of RFC with ABAP stack I have to make of use system number of ABAP Stack in the gateway service,

while registering the ABAP Stack in SLD also make use of system number of ABAP stack in the gateways service...
