Miscellaneous Warnings
**********************************************************************
WARNING: --> Database is using a timezone file older than version 14.
.... After the release migration, it is recommended that DBMS_DST package
.... be used to upgrade the 10.2.0.5.0 database timezone version
.... to the latest version which comes with the new release.
WARNING: --> EM Database Control Repository exists in the database.
.... Direct downgrade of EM Database Control is not supported. Refer to the
.... Upgrade Guide for instructions to save the EM data prior to upgrade.
WARNING: --> Your recycle bin is turned on and currently contains no objects.
.... Because it is REQUIRED that the recycle bin be empty prior to upgrading
.... and your recycle bin is turned on, you may need to execute the command:
PURGE DBA_RECYCLEBIN
.... prior to executing your upgrade to confirm the recycle bin is empty.
.
**********************************************************************
Recommendations
**********************************************************************
Oracle recommends gathering dictionary statistics prior to
upgrading the database.
To gather dictionary statistics execute the following command
while connected as SYSDBA:

EXECUTE dbms_stats.gather_dictionary_stats;

**********************************************************************
Oracle recommends reviewing any defined events prior to upgrading.

To view existing non-default events execute the following commands
while connected AS SYSDBA:
Events:
SELECT (translate(value,chr(13)||chr(10),' ')) FROM sys.v$parameter2
WHERE UPPER(name) ='EVENT' AND isdefault='FALSE'

Trace Events:
SELECT (translate(value,chr(13)||chr(10),' ')) from sys.v$parameter2
WHERE UPPER(name) = '_TRACE_EVENTS' AND isdefault='FALSE'

Changes will need to be made in the init.ora or spfile.
**********************************************************************

- Need speed for upgrading, so truncate AUD$ table and gather dictionary statistics
SQL> truncate table SYS.AUD$ drop storage;
Table truncated.

SQL> exec DBMS_STATS.GATHER_DICTIONARY_STATS;

- Start to upgrade:
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

- Copy spfile + orapw from Old home -> New home.
$ cp /u01/app/oracle/product/10.2.0/db_1/dbs/*oradb* /u01/app/oracle/product/11.2.0/dbhome_2/dbs/

- Use New home to startup upgrade
$ export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_2
SQL> connect / as sysdba
Connected to an idle instance.

SQL> startup upgrade;
