RFC connectivity

[Former Member]

Hi All,

We have a BW system with two application servers connected to a BWA system. Recently, we have replaced one of the BW applications servers with a new server. This replacement was done in such a way that the ip address of the new application server remained same whereas the hostname was changed to a different hostname.

So, we have updated the new hostname in the hosts file of all the blades of the BWA system and the new server server is pingable from all the blades of the BWA server.

Now the issue is, in the Trex standalone tool, under the connectivity tab when we check the rfc connectivity it shows the connectivity for the old BW application server along with the other 2 servers. However, the old application server is already removed and decommissioned.

I removed the RFC connection and recreated the connection, restarted the BWA system, but still the old server entry still persists. Not sure from where the entry is getting populated.

When the BW team is trying to create indexes they are getting an RFC communication failure error.

Could someone help on this?

Regards,

Swaroop
