Why should you use the most recent version of OPatch?

Opatch. A tool nobody really loves but everybody has to use (at least those of you who patch or aren’t in our cloud deployment). Opatch gets distributed via MOS. And you often can apply patches with an older version of OPatch. So why should you use the most recent version of OPatch? Why should you use the most recent version of OPatch? First of all, you have a base installation of Opatch in your $ORACLE_HOMEs: [CDB2] oracle@localhost:/u01/app/oracle/product/12.2.0.1 $ ls OPatch auto jlib opatchauto.cmd operr.bat scripts config jre opatch.bat operr_readme.txt version.txt datapatch modules opatch_env.sh oplan datapatch.bat ocm opatch.pl oracle_common docs opatch…

When you patch, please use UPDATES – and not REVISIONS

I can just repeat what I’m saying not for almost a year: When you patch, please use UPDATES – and not REVISIONS. Updates (or Release Updates – short: RU) and Revisions (or Release Update Revisions – short: RUR) are patch bundles for the Oracle Database since Oracle 12.2.0.1. There are no PSUs (Patch Set Updates) anymore. And Revisions are not the same as PSUs. When you patch, please use UPDATES – and not REVISIONS One of the reasons why we recommend Updates, and not Revisions, simply is: Updates keep you more current whereas Revisions will let you miss a lot…

Patching to Oracle 18.2.0 in the Oracle Cloud (OCI Classic)

I was quite surprised when I spotted the Update (RU) Oracle 18.2.0 mid of April in my OCI Classic (DBCS, DBaaS) account. Of course I was thrilled immediately and started the patching to Oracle 18.2.0 in the Oracle Cloud (OCI Classic). Patching to Oracle 18.2.0 in the Oracle Cloud (OCI Classic) The April 2018 Updates (and Bundle Patches and Patch Set Updates for Oracle releases below 12.2) got released on April 17, 2018. You can read more here on how I applied all of them to my Oracle 11.2.0.4, 12.1.0.2 and 12.2.0.1 databases. But I was positively surprised when I…

Why does your most important database run on Oracle 10.2.0.4?

Today is a sunny day. A wonderful beautiful spring day. Flowers are blooming. Trees are getting green. Birds are singing. All fine. And then I find this email in my inbox. A customer wants to migrate between two Big Endiann platforms with a important ERP system. Nothing special – until I read this: The ERP system is currently on Oracle 10.2.0.4 – and it should stay on Oracle 10.2.0.4. The first question I have: Why does your most important database run on Oracle 10.2.0.4? In 2018. Why does your most important database run on Oracle 10.2.0.4? This is of course…

Do you have to execute catbundle.sql when you create a new 11g database?

Roberto Valsania asked this question once he read my blog post about whether you have to execute datapatch after creating a new 12c database: Do you have to execute catbundle.sql when you create a new 11g database? I’d bet you all are aware that Oracle Database 11.2.0.4 will go out of Waived Extended Support by end of 2018. But that doesn’t answer the question. So I did a quick experiment and created a fresh 11.2.0.4 database to answer the question. Do you have to execute catbundle.sql when you create a new 11g database? First of all, let me clarify what…

Patching my databases with the April 2018 PSU, BP and RU

Patching is fun, isn’t it? And you may have heard already that the April 2018 patch bundles got released on April 17, 2018. And I thought I share a little bit of fun with you with a quick guide to patching my databases with the April 2018 PSU, BP and RU. For this exercise I use our Hands-On Lab with Oracle 11.2.0.4, Oracle 12.1.0.2 and Oracle 12.2.0.1 installed. Prerequisites for patching my databases with the April 2018 PSU, BP and RU First of all, in my VBox environment, I shutdown the databases for each release before patching them – and…

Do you have to execute “datapatch” when you create a new database?

Thanks to Connor McDonald (Mr. AskTom) I learned today that one topic is not clear from our patches readmes: Do you have to execute “datapatch” when you create a new database? And it’s true. It does not get explained in the readme anywhere. Do you have to execute “datapatch” when you create a new database? If you never applied an Oracle patch bundles you may ask now: What is “datapatch” doing. And the answer is very simple. When you apply a patch bundle usually the patch does not include only binary files but also SQL changes, for instance a new…

Databases need to be patched to a minimum before April 2019

Simon Pane from Pythian talked to me at OUGN (Oracle User Group Norway) Conference about a recently released alert in MyOracle Support saying “Databases need to be patched to a minimum before April 2019“. He was curious if I know more details. I did some investigation but shortly afterward the MOS Note got updated as well. So here’s a quick summary of things you should be aware of – but most people won’t be affected I’d guess.   Databases need to be patched to a minimum before April 2019 We released MOS Note 2361478.1 – Oracle Databases Need to be…

Oracle Database 12.2 on Oracle Database Appliance (ODA)?

“Can I download and install Oracle Database 12.2 on Oracle Database Appliance (ODA)?” I received such questions multiple times in the past weeks by different customers. One did ask me about their older X5-2, another person wanted to know where to download the image. At RMOUG somebody asked me when ODA will apply Bundle Patches (or Updates) instead of PSUs? And thanks to my PM mate Tammy Bednar, here’s the information also as a reminder to myself. ODA stands for Oracle Database Appliance – it is an engineered system of software, servers, storage and networking that offers a simple, reliable, low-cost…

Additional Info for Adaptive Features Fixes in Oracle 12.1.0.2

I blogged about the Adaptive Features fixes in the past several times. But following some of the comments readers had I believe there’s some additional info for Adaptive Feature Fixes in Oracle 12.1.0.2 necessary. What happened so far? We delivered the most important fixes not only for adaptive features but only for dynamic sampling and some other things with the Database Bundle Patch in October 2017 for Oracle Database 12.1.0.2. The fixes got delivered on MS Windows a bit earlier. Enabling Oracle 12.2 ADAPTIVE Features in Oracle 12.1.0.2 – BEFORE the patches got included in BPs Oracle 12.2 Adaptive Features…

Are OJVM patches included in the Oracle 12.2 RU / RUR?

I have received this question multiple times in the past days, especially when I presented at the Slovenian Oracle User Group Conference about the new Release and Patching Mode but also via emaill: Are OJVM patches included in the Oracle 12.2 RU / RUR? Let me clarify this in the below blog post. Are OJVM patches included in the Oracle 12.2 RU / RUR? At first I did check MOS Note: 1929745.1 – Oracle Recommended Patches — “Oracle JavaVM Component Database PSU and RU” (OJVM PSU and OJVM RU) Patches.But besides having RU mentioned in the Note’s title and one…

Download Assistant for RUs, RURs, BPs, PSUs, Patch Sets and Releases

How often did I launch a search in MyOracle Support (MOS) for a specific Bundle Patch or Patch Set Update. And usually the MOS search results don’t get me what I’m looking for no matter how clever I search. But there was relief. A MOS Note combined all PSUs and BPs and much more into table format including the links. But what if there would be a Download Assistant for RUs, RURs, BPs, PSUs, Patch Sets and Releases? I did blog about the previous magic note a while back: Where is the Jan 2017 PSU for Oracle Database 11.2.0.4? But…

Oracle 12.2 Adaptive Features are enabled in Oracle 12.1.0.2 Windows BPs

Oracle 12.2 adaptive features are enabled in Oracle 12.1.0.2 Windows BPs already, This is quite a surprise to me. But thanks to Michael Pfautz. He alerted me today.as he was wondering why his database didn’t start up anymore after he applied the August 31 Bundle Patch on Windows. It complained about the parameter optimizer_adaptive_features in the SPFILE. Michael had to remove this parameter before he could startup his database again. Oracle 12.2 Adaptive Features are enabled in Oracle 12.1.0.2 Windows BPs We recommend to add two very important parameters to Oracle Database 12.1.0.2 installations.

How to patch the Oracle Instant Client?

That’s an interesting question a customer raised the other day: How to patch the Oracle Instant Client? I silently assumed that there’s a new release of the Oracle Instant Client every quarter or at least when we deliver fixes which apply to the client as well. Hm … What is the Oracle Instant Client? First of all, the Oracle Instant Client is a pretty cool thing. It gets distributed via OTN as a simple download. You deploy it to your client machine, you set LD_LIBRARY_PATH (or PATH on Windows) and add a tnsnames file if necessary, you may add SQL*Plus…

Oracle 12.2.0.1 RESTART: Make sure you’ve patched your Oracle 12.1.0.2 homes

This blog post title sounds a bit weird, doesn’t it? Oracle 12.2.0.1 RESTART: Make sure you’ve patched your Oracle 12.1.0.2 homes. Why the heck should you patch your 12.1.0.2 database homes upfront? Oracle 12.2.0.1 RESTART: Make sure you’ve patched your Oracle 12.1.0.2 homes Well, there’s an interesting issue happening. When you work with Oracle Grid Infrastructure, no matter if you operate a cluster or “just” use Oracle Restart, you’ll have to upgrade GI to Oracle 12.2 first before you can manage 12.2 databases with it. That’s not new. It’s a well understood rule. Now guess you operate Oracle RESTART (SIHA…

Issue with 2k and 4k db_block_size – ORA-1450 when upgrading to Oracle 12.2.0.1

Recently we got alerted by a customer and a colleague from Italy about an issue with the upgrade from Oracle 12.1.0.x to Oracle 12.2.0.1 if – and only if – your database got created with 2k or 4k db block size.

Oracle 12.2.0.1 Bundle Patch 12.2.0.1.170516 DBBP on Linux x86-64 is available [not anymore]

All credits go to Ricardo Maeda as I knew that we’ll release a Bundle Patch for Oracle 12.2.0.1 sometime this week – but I couldn’t find it linked from the usual MOS notes. And please don’t ask my why that is. Anyhow, with patch 2579308 you’ll get access to the first BP for Oracle Database 12.2.0.1. There will be a first bigger Proactive Bundle Patch in July at the usual schedule – but this one is at least a start. Plus in addition get the OPatch version 12.2.0.1.7 via patch 6880880. The BP contains: Obrigado, Ricardo! Update June 9, 2017…

Use the correct download to patch APEX from 5.1.0 to 5.1.1

When you plan to upgrade Oracle Application Express (APEX) from version 5.1.0 to 5.1.1 please be aware to download a patch from MOS instead the 5.1.1 version from OTN. The text on the OTN page is a bit misleading – and a customer I work with downloaded the wrong version which led to a failed upgrade – even though the scripts seem to be made for this patch upgrade. Even though the page says “This is a cumulative patch set for Application Express 5.1.0” the page offers you a full install and not the patch for an existing APEX 5.1.0…

OPTIMIZER_ADAPTIVE_FEATURES obsolete in Oracle 12.2

The Oracle Database 12.1 parameter OPTIMIZER_ADAPTIVE_FEATURES has been made OBSOLETE (i.e. must be removed from the SPFILE when upgrading) in Oracle Database 12.2. It gets replaced with two parameters of whom one is enabled, the other one is disabled by default: OPTIMIZER_ADAPTIVE_PLANS=TRUE by default OPTIMIZER_ADAPTIVE_STATISTICS=FALSE by default Nigel Bayliss, our “Optimizer” Product Manager has blogged about it already with way more detailed insights. https://blogs.oracle.com/optimizer/entry/optimizer_adaptive_features_in_the But as Oracle Database 12.2 on-premises is not available how should you deal with this feature in Oracle Database 12.1?

OJVM patch: Standby-First patching, yes or no?

I have blogged in the past more than once about the “wonderful” topic of OJVM patching. Anyhow,  I’d like to summarize a few typical questions sent to me in the past months regarding OJVM patching. Do I need to apply the OJVM patch every time I apply a PSU or BP? Unfortunately this is not a one-time-and-then-you-are-set operation. You’ll have to do it every time. How do I find out if OJVM is used in my database? I tried to nail this down in this blog post here: Java in the database – OJVM non-rolling patches – OJVM Removal But…

PDB unplug/plug/patch with PSUs or BPs

This question was posted on the blog a few days ago referring to my previous blog posts describing the two techniques to upgrade in an Oracle Multitenant environment: Everything at Once One at a Time — via unplug/plug Question:  We are planning to upgrade from 12.1.0.2.1 to 12.1.0.2.5. The plan is to create new 12.1.0.2.5 oracle home and gradually moving PDB from 12.1.0.2.1 to 12.1.0.2.5. Should I follow the same steps? Is there any document for what we want to do?
