I'm about to migrate an instance from 8.1.7 to version 184.108.40.206 in Solaris Unix. Both of these version are in the same machine. When I migrate using dbua from $ORACLE9_HOME/bin, I get the error message "ORA-01034: ORACLE not available." I am sure I have started up the database, I have checked the listener and I can connect to the database using another machine. I have shut down and restarted the instance but still cannot proceed. Any help is much needed.
Ensure that the ORACLE_SID and ORACLE_HOME environment variables are set properly, and check to see that the oratab file has the correct ORACLE_HOME for the database you are attempting to upgrade. If all of this checks out and the DBUA still reports this error, you should be able to upgrade the database manually via scripts rather than through the DBUA. For more information, refer to the Oracle9i Release 2 Database Migration Guide found

I'm getting errors while installing the Database Configuration Assistant.
I have been trying to install Oracle 8.1.7 on SUSE Linux 9.0 and got the error:
"Error in invoking target install of makefile /opt/oracle/...../*.mk."
Can I use /var/opt/oracle/oratab to specify listener information?
