For input string: "" Upgrade configuration file /oracle/SND/102_64/cfgtoollogs/dbua/SND/upgrade2/upgrade.xml is not a valid xml fileand the DBUA does not run. Please help as this is my first Oracle upgrade ever!
select temporary_tablespace from dba_users where username='SYS';Then check to see whether this tablespace is locally or dictionary managed:
select tablespace_name, extent_management from dba_tablespaces;If the temporary tablespace defined for the SYS user is a dictionary managed tablespace, try creating another locally managed tablespace and assign it to be the temporary tablespace for SYS as follows:
alter user sys temporary tablespace <new tablespace name here>;Try the upgrade again using the DBUA.
