Hello,



I seem to crawl from error to error during my upgrade from Oracle
8.1.7.3.2 to 9.2.0.5.2.



I'm trying to start the Oracle Database Upgrade Assistant. I skip the
welcome screen and get the step where I must select the database to
upgrade.

There is only one database listed (TST - D:\Oracle\TST\817) that I can
choose. I choose this one and continue. The Database Upgrade Assistant
now shows a dialog "etting Database information - please wait".
Immediately after this, I get an "ORA-12560: TNS: Protocol adapter
error" that I can't get around.



I've already copied the listener.ora, sqlnet.ora and tnsnames.ora from
the old home to the new, but this did not help.



Does anybody have an idea?
