Now for Oracle restart to work properly for this database do the following

ota5013#NGL451T1>>/oracle>srvctl config database -d NGL451T

Database unique name: NGL451T
Database name: NGL451T1
Oracle home: /oracle/home/11.2.0.2.0
Oracle user: grid
Spfile: +DATA/spfileNGL451T.ora
Domain:
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Disk Groups: DATA,FRA
Services:

Now modify the database
ota5013#NGL451T1>>/oracle> srvctl modify database -d NGL451T -o /oracle/home/11.2.0.3.0

ota5013#NGL451T1>>/oracle> srvctl config database -d NGL451T
Database unique name: NGL451T
Database name: NGL451T1
Oracle home: /oracle/home/11.2.0.3.0
Oracle user: grid
Spfile: +DATA/spfileNGL451T.ora
Domain:
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Disk Groups: DATA,FRA
Services:

change in /etc/oratab the oracle home
NGL451T1:/oracle/home/11.2.0.3.0:N

ota5013#NGL451T1>>/oracle>srvctl upgrade database -d NGL451T -o /oracle/home/11.2.0.3.0
This to prevent the oratab to be overwritten with the old oracle home of this database.

Now your done database is upgraded and oracle restart still works for this database.
