MRP3 for Oracle 19.17.0 adds an interesting surprise

You may have read my previous blog posts about MRPs (Monthly Recommended Patches). And today I did a quick check with Rodrigo. We both were a bit surprised to have the MRP3 for 19.17.0 add a lot of fixes to a standard RDBMS installation. So we were investigating a bit further. As a teaser, read on to see that MRP3 for Oracle 19.17.0 adds an interesting surprise.

 

How did we find out?

The MRP3 for Oracle Database 19.17.0 got released just a week ago. You can navigate to it via MOS

Mid-of January. It’s patching time again. So let me show you the quarterly exercise of Patching my environments with the January 2023 Bundle Patches. Let’s see this time if I will have to remove my Data Pump Bundle Patch and the 19.17.0 MRP2 at first when I patch in-place.

As usual, an important annotation upfront: I patch in-place due to space issues. But in reality, you please patch always out-of-place with a separate home. Please see this blog post about how to apply the RU directly when you provision a new home with OUI

RUs contain now all available DST patches

At first, Happy New Year everybody. There was silence on the blog for some weeks but I took an extended longer time off. Well, and once you return, there are some emails in your inbox which need some work. You’ll see several new blog posts getting published in the coming days.

Applying the first MRP for Oracle 19.17.0

A few weeks ago I blogged about the fact that we retired the RURs, and instead release the MRPs (Monthly Recommended Patches). In my previous blog post about this topic you’ll find also an FAQ hopefully answering all the questions you may have (had). And now it is mid of November, so I can show you the process of applying the first MRP for Oracle 19.17.0.

 

How do you get access to the MRPs?

At the moment while I write this, you can find the MRPs only in MOS Note: 888.1 -Primary

Patching all my environments with the October 2022 Bundle Patches

Oh yes, it is patching time (again). And this time I somehow missed the slot since the quarterly critical patch updates got released right during Oracle Cloud World. Since I didn’t want to stretch the hotel WiFi too much – and since I wouldn’t have had enough time to install and write-up this blog post, I do it now with a week of delay. So as usual every quarter, follow me for patching all my environments with the October 2022 Bundle Patches.

As usual, an important annotation upfront: I patch in-place due to …

Silent ORA-918 behavior change in RU 19.17.0 and newer

I think we have the best customers out there. It is incredible what some people find. We would be lost without you, and this blog would contain only a fraction of the information we can share with you. In this case let me explain the silent ORA-918 behavior change in RU 19.17.0 and newer. And all credits go to Peter Lehmann from Deutsche Telekom who found this issue only a few days after we released 19.17.0.

What is happening?

Peter shared an awesome and simple test case with me. A query with ambiguously defined …

Patching News: RURs are gone – long live MRPs

Sorry for the headline using TLAs (three letter acronyms). But I was tempted – and those of you being interested in Oracle Database patching my quickly realize that there are some Patching News: RURs are gone – long live MRPs.

RURs are gone?

Andy Mendelsohn announced the MRPs (Monthly Recommended Patches) in October at DOAG Conference in Nuernberg already. Due to Oracle Cloud World bussiness, I’ve had no time to write about it yet. And the introduction of the MRPs means that we won’t produce RURs anymore after a transition grace period.…

Certifying an application on a specific RU-only is wrong

Well, there are still 80+ comments I need to answer and reply to on the blog. So please be patient – nothing gets deleted or ignored. But it happens that a topic crosses my inbox, and I need to blog about it right now. Today, it is a case where a customer asked me for advice, and mentioned on the side that they are going to 19.6.0 in OCI. In this relation I’d like to explain why Certifying an application on a specific RU- only is wrong.

What’s the story?

Patching most of my environments with the July 2022 Bundle Patches

It’s brutally hot out there. It must be July. And I sit in my cool basement office and start my quarterly patching journey hoping that you can enjoy the sun and the sea somewhere. It is time to do my usual exercise, this time Patching most of my environments with the July 2022 Patch Bundles.

Binary patching is slow because of the inventory

The headline of this blog post may sound a bit cryptic: Binary patching is slow because of the inventory. But actually this seems to be one of the main causes when your binary patching gets slower and slower with every patch you apply.

The more you patch, the worse it gets

Well, this is a tough headline. But you may have read my blog posts about my quarterly patching experience. It actually started with the July 2021 RU in my 19c environment when I wrote:

At least in my environment, both checks with the

How to speed up your database and GI patching

Several of you mailed me already and commented. And I know that I promised this blog post for weeks, if not longer. So let me try to explain How to speed up your database and GI patching. Since this blog post has a longer history, I’d say far over 6 months, it will be a bit longer than the usual posts. At when I started writing it, I decided to split it up into several pieces to make it more digestible but also to allow easier finding of certain topics. I hope it may help easing some recent patching …

Oracle Database 12.2.0.1 – End of Support and Patch Bundles

This will be a short blog post but since I received a number of messages yesterday after I published my usual Patching all my environments with the April 2022 Patch Bundles blog post I need to clarify a few things regarding Oracle Database 12.2.0.1 – End of Support and Patch Bundles.

Premier Support for Oracle 12.2.0.1

If you remember this, the Premier Support period for Oracle 12.2.0.1 ended on November 30, 2020.

Patching all my environments with the April 2022 Patch Bundles

Easter time is patching time. And since I was hiking and biking every day the last week up in the Northern Italian mountains, this blog post is coming with a slight delay. But better late than never.

What does datapatch do when you have different components in PDBs?

The last weeks, literally weeks, I have spent a lot of time with several patching topics. And in order to clean up my inbox a bit I will dump the learning into several blog posts. This one today will be about an interesting case I came across when a customer ran into problems with the runtime of datapatch in an ExaCC environment. Hence, today’s topic will be: What does datapatch do when you have different components in PDBs?

Adding the Oracle 19.14.0 OCW / GI bundle patch to my database home

Actually I planned for a different blog post this morning. But since I have a backlog of unanswered comments accumulated I came across this interesting question from Pedro. He wanted to know how he can patch the OCW component in his database home. So I thought I will show you the process of Adding the Oracle 19.14.0 OCW / GI bundle patch to my database home.

Is this necessary?

That’s a good question for a Monday morning. I think: No, that isn’t necessary for a “Database only” home where you don’t have or …

Some additional information regarding the Oracle 19.14.0 RUs

You may have read my previous blog post about patching all my environments to the January 2022 patch bundles. But since I do this in a very simple non-RAC, non-GI environment, I may not see issues you may have encountered. Some people commented – and I would like to share Some additional information regarding the Oracle 19.14.0 RUs . Still, please, this is NOT a collection of all open issues. I just see this blog post as a summary of the issues I have seen and/or heard about so far.

Patching all my environments with the January 2022 Patch Bundles

It’s patching time. When I checked an SR and had a quick discussion with a customer yesterday, Peter reminded me that it’s patching day. And at about 20:00h CET the new patch bundles appeared on MOS. So let me show you again Patching all my environments with the January 2022 Patch Bundles for 11.2.0.4, 12.2.0.1, 19c and 21c.

Patching all my environments with the October 2021 Patch Bundles

My calendar has no error or NLS conversion issue – I was just way to busy the past two months with seminars. But today a colleague asked me whether my 21.4 install reports a 21.3 Build Label in the trace files. And this reminded me that I should now finally apply the patch bundles from October 2021 to our Hands-On Lab environment. So again, another blog post about Patching all my environments with the October 2021 Patch Bundles.

DBMS_OPTIM_BUNDLE and Out-Of-Place Patching

Well, you see, this is most likely my special DBMS_OPTIM_BUNDLE week. And since I receive quite a number of questions, it may be good to discuss here about DBMS_OPTIM_BUNDLE and Out-Of-Place Patching?

DBMS_OPTIM_BUNDLE and Out-Of-Place Patching

Out-of-place Patching

When you patch out-of-place with a new home – which is clearly our recommendation – you may see another tiny pitfall with DBMS_OPTIM_BUNDLE.

When you check DBA_DIRECTORIES, you will find two directories being related to DBMS_OPTIM_BUNDLE.

SQL> select directory_name, directory_path from dba_directories where directory_name like '%OPTIM%'

DIRECTORY_NAME	     DIRECTORY_PATH
-------------------- --------------------------------------------------
DBMS_OPTIM_LOGDIR    /u01/app/oracle/product/19/cfgtoollogs
DBMS_OPTIM_ADMINDIR  /u01/app/oracle/product/19/rdbms/admin

You see the “19” in the …

DBMS_OPTIM_BUNDLE and disabling another fix

Yes, DBMS_OPTIM_BUNDLE week it is. As I received so many good questions and input after my blog post whether you should enable _fix_controls with DBMS_OPTIM_BUNDLE or not, now I can easily fill the rest of the week with new content. Today it will be about a customer’s question regarding DBMS_OPTIM_BUNDLE and disabling another fix.

Disabling another fix

The setup is pretty simple. Stefan wanted to disable a different fix while he had all fixes from the most recent RU enabled on purpose. Sounds simple but has a dangerous pitfall.

This is what …

Should you enable _fix_controls with DBMS_OPTIM_BUNDLE?

Today, Paul mailed me asking a question we internally discussed many times in the past weeks: Should you enable _fix_controls with DBMS_OPTIM_BUNDLE? And there is no easy simple answer. But I can give a recommendation based on my experience from many projects.

DBMS_OPTIM_BUNDLE – a quick recap

Just in case you haven’t dealt with DBMS_OPTIM_BUNDLE recently, here is a quick recap.

With below procedure, you can list the available potentially behavior changing optimizer fixes in the current patch bundle – and you can turn them on or off at will:

After patching, Spatial Index creation fails with ORA-13249

Thanks again to Peter Lehmann from T-Systems for highlighting this issue to me. After patching, Spatial Index creation fails with ORA-13249. And Peter’s customer was quite worried. But see what may have caused this, and how we fixed it.

What happened?

Peter patched a system from 19.10.0 to 19.11.0. This database has undergone an upgrade from 12.2.0.1 to 19.7.0 before, then got patched to 19.9.0 before. The database has the Oracle Locator only but no Spatial installed. The patching including datapatch worked fine. All seemed to be good. Until the customer tried to …

Patching all my environments with the July 2021 Patch Bundles

It’s patching day again. Hurray! Or not. I realize that at patching day, the 19c bundles are all missing. So wrote this blog post a bit after the usual release day.
