Step create SPFILE ....*ORA-12560: TNS: protocol adapter error.*

Hi All,

by the installation of R/3 4.6C for a pilot system for the upgtrade from 4.6C to ECC 6.0 the installation hangs at step:

-

Create SPFILE: (this step creates the oracle server profile (SPFILE) from the up to now used PFILE (ini<SID>.ora). -

when I try to connect to DB via: connect /as sysdba I get the error message:

ORA-12560: TNS: protocol adapter error.

I know this oracle file can means many things and the R/3 is running fine. I copied the brtool from source system but it does not help. Until now there is no data from source. Its a new installation and we want to fix this error before we began to copy the data to the pilot system.

Anyone from you has a good feedback for me?

Thanks in advance

Atik
