An another way to upgrade a database from lower version to higher version is we have to manually upgrade a database (ie) we have to verify whether it meets all the pre-requests manually instead of using dbua (GUI) / datapump.
Step: 1 Create directory backup, upgrade for taking backup of listener.ora , tnsnames.ora and running the preupgrade.jar files respectively.
Backup TNS Files listener spfile and passwordfile .
[oracle@orcldbs ~]$ mkdir -p /u01/backup
[oracle@orcldbs u01]$ cd backup/
[oracle@orcldbs backup]$ ll

==================
/u01/upgrade/preupgrade.log
/u01/upgrade/preupgrade_fixups.sql
/u01/upgrade/postupgrade_fixups.sql
Execute fixup scripts as indicated below:
Before upgrade:
Log into the database and execute the preupgrade fixups
@/u01/upgrade/preupgrade_fixups.sql
After the upgrade:
Log into the database and execute the postupgrade fixups
@/u01/upgrade/postupgrade_fixups.sql
Step:2 Login to the database & Run the preupgrade_fixups.sql
Step:3 Gather the dictionary statistics it should be gathered before and after performing the upgrade.
SET ECHO ON;
SET SERVEROUTPUT ON;
EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;
PL/SQL procedure successfully completed.
Step:4 Purge the Recyclebin,it gains some storage space and on other hand we have choosen the recovery options.
SQL> PURGE DBA_RECYCLEBIN;
DBA Recyclebin purged
Step:5 Before upgrading Oracle Database, you must wait until all materialized views have completed refreshing.

why dont use dbupgrade tool?
we have that method too. I will post upgrade using auto upgrade tool method in next blog.
nice and detailed information and steps
