Hands-On Lab available: Upgrade to Oracle Database 12.2.0.1

Thanks to Roy – our Hands-On Lab “Upgrade, Migrate and Consolidate to Oracle Database 12.2” is now available for download from OTN.

Instructions and technical requirements are clearly documented on the OTN page as well. The lab is based on Virtual Box and can be easily imported upon download and unzip.

You can always access the lab via the blog’s top menu as well:

Hands-On Lab – Access via the Blog

Inside the lab you’ll find :

  • UPGR – an Oracle 11.2.0.4 database ready to be upgraded to Oracle Database 12.2.0.1
  • CDB2 – an Oracle 12.2.0.1 container database which  adopts the UPGR database after upgrade as a new PDB
  • FTEX – an Oracle 11.2.0.4 database ready to be migrated with Full Transportable Exp/Imp into a PDB in CDB2
  • CDB1 – an Oracle 12.1.0.2 container database – so you can test the unplug/plug/upgrade and many other things

    • Thanks Hans – I recognized it as well when showing the page last week in Milan to customers 😉
      We’ll correct it asap.

      Good catch!

      Hope all is well!

      Cheers

  1. Mike,
    This question does not pertain to the hands on lab. I created a 12.2 (RAC) CDB with one PDB, custom database. After DB creation completed, I found that DBCA did not update the /etc/oratab file. I have tested twice and same behavior. Have you come across anyone having this issue?

    Thanks,
    Arun

    • Arun,

      I haven’t seen this in my case – but so far I created only single instance databases and CDBs.
      Are you on Linux? Is it reproducible on another machine?

      Cheers
      Mike

      • Thanks Mike. I have tested on OEL 6.8 cluster. I also noticed that when I dropped a 12.2 database using DBCA, the DBCA also removed the entry for MGMTDB…!!

        I will soon get a chance to test the DBCA on an Exadata cluster. If I see something similar, I will update this thread.

        Thanks,
        Arun

  2. Dear Mike,

    I want to migrate Oracle RAC 10gR2 (10.2.0.5) on RHEL 5 (no Data Guard) with over 10 TB to Oracle RAC 12cR2 on RHEL 7.

    Please tell me solutions in order to get minimum downtime

    Thanks,

    • Hi, do you get new hardware? Or are you planning to do this on the existing HW?
      What are your downtime requirements?
      Is it a 2-node cluster or a multinode one?

      If I’d assume you will get new hardward, I’d do the following:
      – install Oracle 18c or 19c (once it is available) GI on the new RAC
      – install 18c or 19c (once it is available) database SW on the new RAC
      – install 12.1.0.2 on the new RAC

      Run preupgrade.sql from MOS 884522.1 for 12.1.0.2 on your source and fix everything.
      Then restore your RMAN Backup to the new cluster.
      Then upgrade to 12.1.0.2

      Once completed, run preupgrade.jar for 18c or 19c (from MOS 884522.1) and fix everything.
      Then upgrade to 18c or 19c.

      Done.

      Cheers,
      Mike

      • Dear Mike,

        Thank for your response.

        I think it will take a lot of time to migrate from 10.2.0.5.x –> 12.1. –> 12.2

        With RMAN method, it maybe not work with db size 10 TB to minimize downtime.

        Thanks,
