Thanks you

[@MuhammadAli-fi3mn]

Thanks for the nice video. Just wondering why you used a manual method to upgrade the database instead of using a Database upgrade assistant.

[@Kashyap-Amit]

I didn't find timezone upgrade steps. Also looking for logic, 'why we need to upgrade timezone' I know about it but why not sure

[@itisvikash]

Sir can you upload video on upgradation from 11.1.0 to 11.2

[@dbagenesis]

I already have published it. Search once on KZbin

[@Vone_WorldClass]

This is very clearly explain,but can I create new oracle home upgrade as the same old home location?

[@dbagenesis]

Not really, to achieve that, you first perform the upgrade into new home location, delete old home location (11g) and then perform Oracle Home migration (movement) to old home location. Kind of tedious job.

[@gemuandore7910]

excellent Also after 20 days if I need to revert it to oracle 11G, how do we do that? how do we get the data updated after the upgrade?

[@ankitmehta2460]

Then you have to downgrade. Follow downgrade steps on Oracle docs

sir, can you please help with patching 11g and 12c? Thanks

[@dbagenesis]

Sure, added to my list. Will post videos soon!

[@reginaforka7444]

do you have a video on patching?

[@dbagenesis]

Not yet but I guess when you download the patch, you get a read-me file. This will help you perform the patching.

[@rehantayyab82]

please can you tell which version of linux used in this practical ?

[@dbagenesis]

I guess OEL 6.5 but you can also go for OEL 7.6, which I currently use for all trainings.

[@rehantayyab82]

ok thanks ...... both possibilities are there i think installation of 12c on oel 5 ( if 11g already running on oel 5 ) or if 11g running on oel 6 than 12c on oel 6 as well am i right ?

[@joeyhcmc]

How was the data in 11g transferred to 12c? Via expdp utility or pointers to db file will be pointed to the original db files location in 11g?

[@dbagenesis]

There is no need for data transfer, once you perform the upgrade, the 11g DB will be running from the new Oracle home 12c.

[@masudhasan9315]

how do i register my oracle database active data guard license?

[@surajkhanna1735]

Can this work for 11.2.0.4 to 19 c also ?

[@rameshkumar-lf4nd]

Hi Arun, Would you please let us know what is the significance of timzone upgrde to a minimum supported number w.r.to the version we are going to upgrade? What would happen in case if the timezone is not upgraded during the DB upgrade? One more doubt like would oracle DB run with higher version binaries without DB upgrade by simply starting up the old DB under new oracle version? Thanks in advance.

[@dbagenesis]

If the Pre-Upgrade Information Tool instructs you to upgrade the time zone files after completing the database upgrade, then use the DBMS_DST PL/SQL package to upgrade the time zone file. Applying a change to the database time zone file not only affects the way new data is handled, but potentially alters data stored in TIMESTAMP WITH TIME ZONE columns, so you need to consider the impact of this before upgrading the time zone file.

[@jasonstewart1504]

What is the purpose of validating invalid objects? Also how do you backup ORACLE_HOME and ORAInventory? respond ASAp Thank you.

[@thetechcafe754]

How much time it took for the upgrade?? It seems from your log that it took 89000 sec, is it?? Can you share some information regarding how much time it take for a upgrade of a normal sample db??

[@rajatsanwal9919]

I am wondering this too . This is huge time to be spent in db upgrade.

[@lindabrown7470]

During the installation portion of this video, why did you select all the groups to be 'dba' and not 'oinstall'? Just curious...

[@dbagenesis]

you can choose either it will work

[@lindabrown7470]

Thanks!
