DBUA Deprecation and future Desupport in Oracle Database 23c

Daniel pointed me to Tim Hall’s blog post about deprecated and desupported features in Oracle Database 23c. And his first bullet point mentioned is the DBUA Deprecation and future Desupport in Oracle Database 23c. Since Daniel and I agree that this needs a bit more explanation, we would like to share more background information with you.

Deprecated vs Desupport?

At first, let me refresh an old topic. What does deprecated mean, and what is the difference to desupport? A long while ago I wrote this blog post about it, and nothing …

Posted on June 16, 2021 by Mike.Dietrich Exadata / ODA Oracle Database 19c 23

Why is this important?

Until a week ago, the database upgrade MyOracle Support (MOS) note showed the process using the DBUA. And we had plenty of customers asking us why AutoUpgrade isn’t mentioned there. Our team worked already with some of you, and we knew that AutoUpgrade works perfectly fine and takes over some manual actions.

But our MAA team wanted a perfect solution. They …

Do we offer patched Gold Images already?

Posted on January 28, 2020 by Mike.Dietrich Installation 9

Internally we can use a Gold Image service at Oracle. I can download a zip with 19.6.0 included. But externally for you as customers, the download of 19.6.0 required that you download 19.3.0 at first, then apply 19.6.0 on top of it. But a day ago, a tweet by my Belgium friend Philippe Fierens caught my attention. Do we offer patched Gold Images already?

Automatic SQL Plan Management – Slight Change with 19.4.0

Posted on October 2, 2019 by Mike.Dietrich Oracle Database 19c SPM - SQL Plan Management 2

I did blog in more detail about Automatic SQL Plan Management in Oracle 19c. And Roy and I had really a lot of discussion in every customer meeting at OOW19 about it. But there is a slight change to where the feature is available with Oracle 19.4.0.

Slight Change

When you compare the settings of SQL Plan Management between Oracle 19.3 and 19.4, you’ll see the difference:

column parameter_value format a45
column parameter_name format a25
set pages 200

SELECT PARAMETER_NAME, PARAMETER_VALUE
  FROM   DBA_ADVISOR_PARAMETERS
  WHERE  TASK_NAME = 'SYS_AUTO_SPM_EVOLVE_TASK'
    AND PARAMETER_VALUE <> 'UNUSED'

Conventional INSERTs into HCC tables may be slower since Oracle 12.2

Posted on November 28, 2018 by Mike.Dietrich Flaws and Pitfalls 2

I work with several customers at the moment on their Oracle 12.2/18c “go live” projects. And one of these customers encountered a strange issue when comparing Oracle 11.2.0.4 to Oracle 12.2.0.1/18.3.0: Conventional INSERTs into HCC tables may be slower since Oracle 12.2. Actually in this particular case, significantly slower. Read below why this can happen and how the workarounds look like.

Hybrid Columnar Compression

There’s a lot of material to read and study about Hybrid Columnar Compression (HCC). With HCC we store the same column for a group of rows together. The data block does not store data in row-major …

Ouch … just realized that it has been a while since I posted a new topic on the blog. But actually the past weeks I was busy doing workshops, working with customers – and finally (yes!!) participating on an Exadata training class. Sitting there for 3 days, listening the instructor, playing around with the cell simulator and all the exercises was quite a nice change from the daily business. And I believe I’ve learnt something useful 🙂

Well, daily business, this brings me back to a topic which hit my inbox today again for the 2nd time in a …
