Re: sapstart.exe=>sapparam(1c): No Profile used - critical Production Migration issue

i have resolved this issue

the issue was due to the Host name length!! the permitted length of a host name for ABAP installation on windows/oracle is only 12 characters. but my host name was 14 characters.

611361 - Hostnames of SAP servers 

849423 - Length of hostname for ABAP installation on Windows/Oracle

thanks everyone
