SDM connecting to localhost but not Logical Hostname

91 Views

While installing Netweaver AS Java I faced an issue with SDM. During the install software phase(SAPINST) the SDM was not able to deploy few .SCA files. Both server0 and SDM was in Running status.

What we found that, the command telnet was working with localhost and not the logical hostname.

>telnet localhost 53308 is connecting

but >telnet ngdhidaiz1 53308 is not connecting.

So we tried with first doing a reboot of the hardware/server and later on uninstall SAP.

I started fresh installation and this time the installation was successful. I applied the latest support patches and upgraded the kernel. After this, I stopsap Java.

Now today When I tried to start the SAP the server0 and SDM started but the portal was unavailable.

I tried to check with telnet and it again was not connecting to logical hostname <ngdhidaiz1> bt localhost was connecting.

I tried to check the sap notes about the errors/problems but no help.

We can only found that there could be issues with etc/hosts file entries. But all entries were correct and no duplicate entries.

I do not have a proper way to resolve this issue other than trying to reboot the server and start the SAP.

If anyone can help on this it will be great. Thanks
