Upgrade from 11.2.0.4 to 19c with Label Security Policies

I remember, I have a blog. Forgive me that I don’t write a lot at the moment even though I still have a long queue of “future posts to write”. It is just too busy, and I was away for almost two full weeks in June as well. But let me briefly drop information on an issue I learned about recently. It just affects your when Upgrade from 11.2.0.4 to 19c with Label Security Policies. All other readers may simply ignore this blog post.

How to get access to download older Oracle versions?

Today a friend asked me whether I know where to download Oracle 10g. Not a typo where I mixed 9 and 0 on my keyboard. So what if … How to get access to download older Oracle versions?

In the Software Delivery Cloud (formerly known as eDelivery) you will find the following base releases of the Oracle database:

It’s always the Optimizer, isn’t it?! – Part 1

Wouldn’t you agree?

My colleagues from the Optimizer Development might forgive me but a lot of people would say: “Everything went fine after upgrade – except for those tiny 3 queries!”. And I know, you have tested a lot. I’d like to tell you about a few issues we’ve seen post upgrade with 11.2.0.2.

  1. You have captured your plans in Oracle 10.2 pre-upgrade.
  2. You have moved these plans from your SQL Tuning Set into the SQL Plan Baseline in Oracle 11.2.
  3. But the optimizer doesn’t pick them although you have:
    (a) ACCEPTED and
    (b) FIXED them.

Why?

It’s been a while … sorry for not updating the Blog this frequently in the past weeks 😉

But now I’m back in business and today I’m updating our major slide set with some new stuff. And while I’m updating it I thought about what would be the most important MOS (My Oracle Support) Notes on Database Upgrades.

Actually I would say you should start here – and these Notes should guide you to the most important bits and pieces around upgrades. I won’t claim that this is THE final list so you might have a look into our comprehensive …

Thanks to all attendees in Seattle and Toronto

Seattle - APEX 2011
Must be an Oracle sponsored number plate … 😉

Thanks to everybody who did attend to our Upgrade Workshops in Seattle and Toronto past week. Seattle had a quite unusual track setup with two parallel breakout sessions. We hope you’ve enjoyed it as well. And you’ll find the slides for the keynote “New Features” and the “Upgrade Workshop – The Whole Story” presentations below.

Toronto 1

Toronto was quite amazing as well – with so many (hope not too many) people in this slightly crowded room at the Interconti in Toronto. We’ve got a lot of interesting and sometimes challenging questions. …

Will gathering fixed object stats reduce recompilation time post upgrade?

Interesting question, isn’t it?
Will the time to recompile invalid objects post upgrade decreased once fixed object stats have been gathered?

First of all fixed object stats on X$-tables won’t be gathered by default [This will change with Oracle 12c where it is part of the Auto Stats Gathering job].
X$ structures are undocumented. V$ views are build on top of them and
should only be used even though it might be sometimes useful to access
X$ tables such as X$BH (buffer headers – contains information describing the current contents of a piece of the buffer cache

Move to Locally Managed Tablespaces

As I’ve got asked during the workshop in Warsaw how to migrate Dictionary Managed to Locally Managed tablespaces here’s some additional information and an example.

To find out if a tablespace is dictionary or locally managed you’d use this query:

SQL> select TABLESPACE_NAME, EXTENT_MANAGEMENT from DBA_TABLESPACES;

The procedure to migrate to locally managed tablespace is:

SQL> EXECUTE DBMS_SPACE_ADMIN.TABLESPACE_MIGRATE_TO_LOCAL(‘tbs’);

And the whole migration procedure would look like this:

STARTUP RESTRICT EXCLUSIVE;

EXEC DBMS_SPACE_ADMIN.TABLESPACE_MIGRATE_TO_LOCAL(‘TBS’);
— do this for all tablespaces except SYSTEM, TEMP and SYSAUX

DROP TABLESPACE TEMP;
— necessary if there’s no “real” temp tablespace definded yet – see Note:160426.1

New hidden parameters in Oracle 11.2

We really welcome every external review of our slides. And also recommendations from customers visiting our workshops.

So it happened to me more than a week ago that Marco Patzwahl, the owner of MuniqSoft GmbH, had a very lengthy train ride in Germany (as the engine drivers go on strike this week it could have become even worse) and nothing better to do than reviewing our slide set. And he had plenty of recommendations.

Besides that he pointed us to something at least I was not aware of and added it to the slides:

11.2.0.2 Bundled Patch 3 for Linux x86-64bit released


NOTE ADDED ON 25-MAY-2011


Please be aware that this entry has been published a long while ago. As of today (end of May 2011) Exadata BP10 (and not BP3) is the most recent Bundle Patch. And me and some colleagues have learned in the past months that applying Exadata BPs to a non-Exadata environment might cause some trouble once you request an one-off/interim patch on top of an Exadata BP.


Officially this Bundle Patch for Oracle Database 11.2.0.2 is titled “Exadata Database recommended patch” and got released yesterday. But I would recommend this one to all customers using 11.2.0.2 Grid …

Patch Set 11.2.0.2 for Win32 and Win64 now available

Oracle Database Patch Set 11.2.0.2 for Windows (Patch: 10098816) is now available for download from support.oracle.com:

  • Installation will be done by default into a separate %ORACLE_HOME% .- and this is our strong recommendation.
  • If you’d like to install into your existing

Recap on Deinstall Routines

A few weeks ago I’Ve posted something about the deinstall utility as OUI doesn’t offer a “deinstall software” option anymore:
How to deinstall “old” SW after 11.2.0.2 has been applied?

And I’ve got some feedback (which is a good sign as it means that some of the content might be useful and will be read – and from the follow-up you see that we’ll read your comments and emails as well 🙂 ).

Anyway, the feedback was either CRS deinstall does not work the right way or deinstall cleans up too many things. So Roy did follow …
