Upgrade 11g to 12c

In our environment plan to upgrade to 11g to 12c
Currently we are using 11.2.0.1 version standard edition
How to upgrade to 12c
Please give some suggestion about this

Hi,
To upgrade to 12c from 11gR2, DB should be of minimum version 11.2.0.2 or later.
As you are on 11.2.0.1, you will have to first upgrade the DB to 11.2.0.2 or 11.2.0.4.
11.2.0.2 software can be downloaded as patch # 10098816 from My Oracle Support ("Patches and Updates" tab)
11.2.0.4 software can be downloaded as patch # 13390677 from My Oracle Support ("Patches and Updates" tab)
Let us consider you have chosen 11.2.0.4 here.
There are two stages as shown below.
Stage 1: Upgrade to 11.2.0.4
1. Install the new 11gR2 software 11.2.0.4 in a new separate ORACLE_HOME. During installation, you will be prompted to choose "Edition" where you can choose "standard" if thats your requirement.
2. Perform the upgrade of 11.2.0.1 DB to 11.2.0.4 using Manual upgrade method or DBUA method.
Doc ID 870814.1 => Steps to upgrade to 11gR2 using DBUA method (applicable to 11.2.0.4)
Doc ID 837570.1 => steps to upgrade to 11gR2 using Manual method (applicable to 11.2.0.4)
Stage 2: Once the DB is confirmed to be successfully upgraded to 11.2.0.4, then you can start the upgrade to 12c.
12c software can be downloaded from below link.

SOA Composite upgrade 11g to 12c pitfalls

We have quite a few SOA Composites from 11g we need to 12c, are there any pitfalls we should be aware of? We are going to test a few first but appreciate any words of wisdom. Thanks, Tom

Thanks Vamseeg! I will make sure and use 12c JDeveloper to perform them. I appreciate you responding. Have a great day! Tom

Need methodology for upgrading/migrating CRS Home from 11g to 12c RAC.

Hi
Is there a detailed step-by-step guide on how to migrate from Windows 64bit RAC dual node cluster from 11g to 12C?
So far I've found lots of documentation related to Linux, not Windows.
Cheers

Upgrade Weblogic 11g to 12c on JD Edwards Templates

Hi
I am running into issues upgrading to Weblogic 12c on JD Edwards VM templates (http://docs.oracle.com/cd/E24902_01/doc.91/e37833/ch_undvmtem.htm#EOIOV107).
The installer stops because MW_HOME is not defined. My questions is where should I point MW_HOME to on the Linux machine.
The installer automatically selects:
/u01/app/oracle (but this is empty)
The Middleware directory can be found:
/u01/Oracle/Middleware
Under this directory there are a number of directories including the "user_projects" and "wlserver_10.3"
Any advise or update prerequisites would be appreciated.
Thanks
Mac

MW_HOME chosen as /u01/Oracle/Middleware is correct.
The files "user_projects" and "wlserver_10.3" are related to Weblogic Server.
Let me know what issues are you facing after choosing MW_home ...

Hi,
I debug the application, I found my @ViewScoped ManagedBeans, they're recreated after you click a button or select a item in combobox
Here is a piece of code:
    @PostConstruct
    public void resolveEntity() {
        Object sEntity = FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("entity");
        entity = (BctTbOportunidade) sEntity;
         FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove("entity");
        if (entity == null) {
            entity = new BctTbOportunidade();
I use @postConstruct to get a entity from another page in sessionMap(I set a item from a table and use this method to modify a entity in a other page).
When I click a button or select a item in combobox in same page @PostConstruct method is called but values are lost. No Exceptions are thrown by server.
I found a artice written by BalluC that some versions of jsf 2.1 has this behavior The BalusC Code: The benefits and pitfalls of @ViewScoped
I already configured my web.xml to set false javax.faces.PARTIAL_STATE_SAVING
But this behavior continues.
The jsf version deployed in my weblogic 12c is 2.1.7.

Which track to take for DBA OCA: 11g or 12c?

Hi,
I want to do become an Oracle Database Administrator Certified Associate (OCA).
Which of the 2 options should I take? 11g or 12c?
I am actually a developer (Forms & PL/SQL) trying to become a DBA.
Your advice would be greatly appreciated.
Thanks & Regards

I want to do become an Oracle Database Administrator Certified Associate (OCA).
I am actually a developer (Forms & PL/SQL) trying to become a DBA.
Why? How will having an OCA certification bring you closer to your goal?
Which of the 2 options should I take? 11g or 12c?
Take the 12c path -
1. that is where everything 'Oracle' is headed.
2. companies will be increasingly upgrading/installing 12c as time goes by
3. people will knowledge about 12c will be more and more in demand as time goes by
4. people will knowledge about 11c will be less and less sin demand as time goes by
5. the 12c knowledge you gain will become more and more useful to others (e.g. DBAs and your manager) at your company as they consider when, or if, to upgrade their databases to 12c.
6. 12c knowledge will likely make you more valuable to your current company even before you get your certification. Managers like people that take the initiative to learn something new especially if that 'something new' is a skill that will be useful to the company.
7. the exam costs for 12c is the same as for 11g
For 11g see - http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=458&get_params=p_track_id:Datab11g
For 12c see - http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=458&get_params=p_track_id:DBOCA12C
8. you can freely download and install 12c for learning and practice just as you can 11g
The only downside I can think of is that there are fewer people you can turn to for help with any 12c-specific questions or issues you may run into. But there are plenty of books and online tutorials/articles that cover the bulk of those.
BACK TO THE FUTURE!

What are the things we need to take care while moving from 11g to 12c.

Dear All,
One of my client having the application running on 11g and now he wants to move it on 12c.
Now he is asking to me that, what are the things will not work or impacted due to this. Any code level changes, syntax, functions etc are working in 11g and now there is difference or not working in 12c. Could you please help me in this.
Is there any document for all these thing. I searched on google but not able to find any specific doc.
Thanks in advance.
Regards,
ganesh

Database in 11g will now act as PDB's in 12c.
And what makes you say so? What about the changes/fixes done in the optimizer that would alter the plans? What about if the client wants to use in-memory database option? And your statement that database in 11g will now act as PDB in 12c doesn't make any sense. What if the client is not willing to move to multitenancy? What about the scripts that are running in 11g without any issues and suddenly, will break in 12c due to PDB's ? Do you have any technical reference to validate your claim that there won't be any impact ?

Tpnotify with TPACK flag hangs after upgrading to Tuxedo 12c RP020

Hi,
We are experiencing issues with tptonify with TPACK flag set after upgrading to Tuxedo 12c. Looks like tpnotify is not returned or reporting errors. Is there anything to do with "009. Bug16506218 - TPNOTIFY WITH TPACK FLAG THROW OUT EXCEPTION"? Is there any documentation about the new flag TPACK_INTL?
Thanks

Hello,
If all you have done is upgrade to Tuxedo12 the behavior should be the same. The TPACK flag definition is:
"The request is sent and the caller blocks until an acknowledgement message is received from the target client"
Is there any additional change(e.g. in your client) you have made?
What Tuxedo version are you upgrading from?
The bug 16506218 fix was for a jolt client exception and a JSH failure.
Do you see an error or is the process which executes tpnotify() just hanging/blocking waiting for the ack message?
The flag that you mention is actually an undocumented customer requested enhancement that went into Tuxedo 10.3.
Are you using it? Using it changes the tpnotify() behavior dependent upon the client status.
Regards,
Bob Finan

For our last attempt, space free before install is 30Gb; space free when this dies is 21Gb.
Any suggestions?

Hi, Can you pls open an SR and upload all the logs-
- $ORACLE_HOME/sysman/log/schemamanager zipped
- $ORACLE_HOME/cfgtoollogs/ zipped
- central inventory logs
Share the SR number so that we can look at the logs. I hope you went through the - Note 1494890.1 - Checklist for Upgrade from EM 12.1.0.1 to EM 12.1.0.2
Is this your test system or prod system upgrade.

Oracle 11g and 12c on same windows 7 machine

Hi folks,
Want to try out 12c on my windows 7 laptop but still want to keep my 11g database.
Anyone tried running Oracle 11g and 12c on same windows machine?
Any links or guidelines are appreciated
Thanks

you won't be the first or the last person to try it.
this question can be easily answered but why question something that it's easier to test by yourself?
My advice: Try and if you have problems then question us.

Install WebLogic 11g and 12c to deploy Unifer

Does this mean I need to install both 11g and 12c to make deploy unifer. I wonder why does it need both.

FYI. You do not need to install both 11g and 12c to deploy Unifier. For testing purposes i was able to deploy unifer on 11g weblogic server by creating a domain and deploying it. It seem that 12c is only needed if you have multiple server applications

FMW 11G with 12c database

Our DBA's are looking into upgrading our database to 12c (probably 12.1.3).The Oracle Fusion Middleware 11g Release 1 (11.1.1.x) Certification Matrix says "Oracle DB 12.1.0.1+ certification is available only with WLS 10.3.6+/FMW 11.1.1.7+". Does that mean we can use Oracle database 12.1.3 with WLS 10.3.6/FMW 11.1.1.7 and greater.
Any pointers will be of great help.
Thanks,
RT

Yes, you can use the RDBMS 12.1.3 with the WLS 10.3.6. Please refer to very helpful MMOS Note: WebLogic Server 12.1.1 and 10.3.6 Support for Oracle 12c Database (Doc ID 1564509.1)

I recollect in 12.0, not 12.1, there was a required OVM password deep in a hidden nook in the OEM Infrastructure Cloud GUI, I cant find it in 12.1, could this be the issue?
Respectfully,
Roddy

A quick update, Oracle support just informed me the 3.1.1 is not certified with OEM 12c 12.1. Not very helpful information, but its a start.
At first glance it appears that the OVM development team made changes that break the virtualization plug-in.
Any assistance and/or workarounds would be greatly appreciated!
