I've upgraded from Oracle 11g 184.108.40.206 to Oracle 11g 220.127.116.11. I'm trying to run DBUA to perform a database upgrade. When I run DBUA I get the following message:
There is an error in creating the following process:
/var/databases/oracle/bin/sqlplus -S /NOLOG
The error is:
/var/databases/oracle/bin/sqlplus: not found
I want to know:
1)when I ran DBUA, does the $ORACLE_HOME direct to the 11gR2 home or the old one?
2)the entry in the /etc/oratab is db sid:old oracle home,is it correct?I think there should be the old oracle home,not the new one.
