2. ORA-32004 is usually related obsolete and/or deprecated parameters when attempting to start a database: ORA-32004: obsolete and/or deprecated parameter(s) specified. The parameter initialization file should be checked to see that none of the specified parameters match a parameter name stored in the V$OBSOLETE_PARAMETER view of that same database.
