How to check whether RFC port is opened or Not

[former_member422777]

Hi I am using a RFC FM. Now i want to check whether the RFC port is opened or not. Can you please tell me is there any standard flag to check ?

Hi ,

Check this FM /BDL/_GET_RFC_DESTINATIONS

* write target destinations into internal table
select * from /bdl/sesdest
          into corresponding fields of table rfcdest
          where sessno = session_number
            and client = session_client.

if sy-subrc <> 0.
   init_msglog_sessmand session_number session_client.
   msg_log_line =
   'No RFC destination found: transfer not possible'."#EC NOTEXT
   warning msg_log_line.
   raise dest_not_found.
endif.

We had a problem with an RFC destination that periodically was unavailable. I wrote the following  program (in the attached file) to check if the destination was available, and create a background event if it was unavailable. Hopefully the program is self-explanatory.

Hi Andy,

Port open is one time activity and it will open if we placed request to basis.  I think no need to check each time whether port is open or not.  Any specific reason are you cehck in program whether open port or not before call function.

As suggested in earlier blog check SM59 window and check wther able to connect target sytem or not.

Hope this will help you.

Hi Andy,

You can use RFC_PING_AND_WAIT FM to make sure connection is available or not before calling your custom built RFC FM.

Hi,

You can use telnet <IP ADD> <PORT> and check if you are able to connect to it.

RFC usually goes over the SAP Gateway, so you can check in transaction SMGW on the destination system to see the gateway log, this will tell you which port it is listening on and whether it is working.

Hi Darryl, i want to use a flag in Program which will gives me next path. like which port is opned and according to that i want to use the if...endif cases.

Aha, I understand.

This is an RFC enabled program that you are writing.

You need to ask an ABAP developer about that.  I'm not an ABAP person.
