  1. Looking at edelivery, only the DB software is marked as ‘Exadata-only’ but GI isn’t. Does this mean that GI should be expected to work on non-Exadata hardware?

    • Karsten,

      as currently 18c got released for Exadata and Cloud only I wouldn’t take the GI version regardless of being labeled as “exa only” or not. I’m with you, most likely it may be the same software. But I can’t guarantee that. And you may get strange questions from support when you open an SR (just guessing).

      Cheers,
      Mike

      • Mike,

        you’re right, I am getting strange questions from support. For example ‘where did you get this’. πŸ™‚

        Cheers,

  2. Hi Mike,

    Thanks for sharing this. Love some of the new features of Oracle 18c, especially the Microsoft AD integration. We have been waiting for this feature for years !

    Can’t wait for the on-prem release.

  3. Hello, Mike,
    Thank you for sharing your experience !

    I have one question.
    Usually oracle make some patches combining GI + RDBMS of the SAME RELEASE and PATCH LEVEL. For example:
    GI 11.2.0.4.171017 + RDBMS 11.2.0.4.171017 or
    GI 12.1.0.2.171017 + RDBMS 12.1.0.2.171017
    GI 12.2.0.1.171017 + RDBMS 12.2.0.1.171017

    And Oracle confirm that it TEST, for example GI 12.1.0.2.171017 + RDBMS 12.1.0.2.171017 as working together.
    So, we sure in such a combinations.that GI 12.1.0.2.171017 + RDBMS 12.1.0.2.171017 were tested.

    But Oracle NEVER combine in one file different releases or different patch levels:
    GI 12.2.0.1.171017 + RDBMS 12.1.0.2.171017 ΠΈΠ»ΠΈ
    GI 12.1.0.2.171017 + RDBMS 12.1.0.2.170418.

    On this basis, our customer draw a conclusion that Oracle DON’T TEST such a combination as working together. Is it right ?
    Say, please, a few words about how Oracle test the stack: RDBMS + GI (different releases and different patch levels.)

    Than you !

  4. 18c DB software EXADATA although Oracle says is GA the software is not available. The software in edelivery is not 18c although it says its. When I tried to install it says 12c

    V974953-01.zip is branded as 18c but its not.

    • Sanil,

      I’ve seen blog posts of people (yesterday) who patched their Exa up to 18c already with the download from eDelivery.
      Would you mind to drop me an email (firstname.lastname Ε“ oracle.com) with your findings and screenshots?

      Thanks,
      Mike

  5. Mike,
    Is MOS note 2111010.1 still good for upgrade to 18c? Since technically 18c is 12.2.0.2, the same MOS note should be applicable, right?
    Thanks,
    Arun

    • Arun,

      I’m not 100% sure. Most parts of the note still apply as (as you mentioned already) 18c is 12.2.0.2. But I know that some tiny pieces changed. So far the feedback I’ve gotten from customers doing the move on their test Exadatas all is fine. And I know that the MAA team is working on a revision of the note for 18c.

      Cheers,
      Mike

      • Thanks Mike. I did upgrade the GI to 18 and installed DB 18 software. There was no need to apply any one-off patches and the upgrade went smooth. I am seeing one issue. When I use oraenv to set environment variables for any 11.2.0.4 DB, I am getting this message:

        ORACLE_BASE environment variable is not being set since this
        information is not available for the current user ID oracle.
        You can set ORACLE_BASE manually if it is required.
        Resetting ORACLE_BASE to its previous value or ORACLE_HOME
        The Oracle base remains unchanged with value /u01/app/oracle

        This never used to happen prior to upgrading the GI to 18, not even with 12.2.0.1. Do you happen to know if anyone else is experiencing the same issue?

        Thanks,
        Arun

        • So the problem of ORACLE_BASE is caused by oraenv file being replaced by the R18 DB oraenv. The R18 DB oraenv file does not set the ORACLE_BASE correctly. I replaced it from an non-upgraded server and it worked. The file sizes and timestamp are different, so something has changed.
