I was trying to create a database during installing Oracle8i EE (8.1.7) on Solaris 8. It failed when the database creation progress went to initialize database (Creating and starting Oracle instance, copying database files are OK. I used the typical option to create database.) I got a error message:
ORA-03114 : not connected to ORACLE
After installation, I tried to use dbassist to create a database and got the same result. So now there is no any database existing in my Oracle 8i.
