RFC connection problem

[Former Member]

Hi All,

I have a problem here.

I have 2 servers BW dev and BW prd. (version BW 3.5)

The IP address of BW dev has to be changed. So we did that.

Now BW dev is up and running. Everything working fine

But the RFC connection from BW prd to BW dev (with new IP) is not working.

It gives the error of " no conect of TP sapdp00 from host bwdev"

I have changed the entries in etc/hosts file and DNS settings.

Is there any setting I need to do in /etc/services file.

I have checked the table RFCDES. There is hostname stored there (no IP).

The RFC from BW dev to BW prd is working fine. But the otherway around is giving problem.

Is there any file or table where the entry of IP to corresponding hostname gets stored.

When I type the hostname while making a RFC connection (SM59) in BW prd to BE dev, It brings the Old IP (of BW dev)in the save as IP address box.

But when I write hostname with domain name bwdev.company.com, then shows the correct IP (new one).

So because of these, transports are also not possible.

My OS is AIX and Netweaver 2004 and DB is oracle

Kindly help

Hello,

If you are sure your dns settings and hosts file definitions are correct, please refresh hostname buffer via tx-code sm50. After that, go to sm59 and try again.

alsı, you can give new ip address on sm59 rfc destination, instead of hostname

Hi

Once go to BI DEV server and then go to SM59 t-code there u delete the existing RFC and recreate the New RFC connection with new IP then mostly ur problem will be solved.

Hi,

How to refresh hostname buffer from SM50.

I tried to make a new RFC but it did not help.

I tried to enter the IP address instead of hostname. But as i hit enter, it changes back to the hostname and the IP address is shown in save as box below.

What could be the problem?

Thanks,

another way:

In transaction SMGW choose Goto -> Expert Functions -> Host name buffer -> Reset

Hi Arzu,

Thanks for your replies.

I refreshed the host name buffer from SM51.

It solved the problem. Then I made a new test RFC destination for DWdev and it worked.

Then I regenerated transport RFC destibations and that start to work too.

Thank you vey much to you and panda

I am happy to award you points

Thanks,

Tajinder
