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

As usual I download the patch bundles  and apply them to our Hands-On Lab environment as quickly as possible. First of all for the simple reason that I don’t want to trap into issues which are fixed already. Second for the reason that I always tell you: YOU MUST PATCH! But if I’m saying this over and over again, then I can’t have my own environments unpatched. And at third, because I want to learn if anything is not working correctly or has changed (see below). Of course my tiny single instance environments are not comparable to your critical production…

July 2018 Update, Revision, BP and PSU

Hurray, it’s patching day! I know, YOU did look forward to July 17, 2018 as it is patching day again. Last night we released the following Patches: July 2018 Update, Revision, BP and PSU. July 2018 Update, Revision, BP and PSU First of all, I’m doing the usual check for the alert and the risk matrix to see whether there’s are really important security patches included. For the risk matrix you’ll have to scrooooooooooolllll down quite a bit as the list of products is strictly alphabetically ordered: Critical Patch Update – July 2018 – Patch Advisory Risk Matrix for Oracle…

Data Pump 12.1.0.2 – Wrong Dump File Version – ORA-39142

Again I’ll have to thank my colleague Roland Gräff from the German ACS Support team in Stuttgart for bringing this into our radar. Roland alerted me a week ago about an issue with exports in Oracle 12.1.0.2 only when you are on a certain patch level. I summarize the issue here under Data Pump 12.1.0.2 – Wrong Dump File Version – ORA-39142. In the below blog post you will learn about the actual issue, where it happens and when, and of course how to workaround it. When does it happen? The issue I will describe below happens only with Oracle…

Special characters show junk in CLOB columns after upgrade to Oracle 12.2.0.1 with JDBC

Thanks to my support colleague Roland Graeff who told me about this issue at a customer today. And I consider this a pretty serious issue. It can happen that Special characters show junk in CLOB columns after upgrade to Oracle 12.2.0.1. with JDBC. This is as bad as it sounds. Roland told me about a case where the application showed weird characters instead of German umlauts (ä, ö, ü, Ä, Ö, Ü) after an upgrade from Oracle Database 12.1.0.2 to 12.2.0.1. Special characters show junk in CLOB columns after upgrade to Oracle 12.2.0.1 with JDBC Roland explained to me that…

Patching Oracle Database 18.1.0 to 18.2.0 on premises

In this part of my blog post series about upgrading from Oracle 12.2.0.1 to Oracle 18c I’d like to demonstrate patching Oracle Database 18.1.0 to 18.2.0 on premises. A while ago I showed also how to patch from Oracle 18.1.0 to 18.2.0 in the Oracle Cloud.

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…

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

CORRECTION: After I published this blog post saying “April 2019” my fellow support colleagues changed the alert to “June 2019”. Just saying … the topic itself is still the same. 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 June 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…

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…

Oracle Database RU and RUR Recommendations and Facts

Well … another post about RU and RUR patches. But after having multiple discussions personally, via web conferences, in conference calls and of course on Twitter I think some clarifications may be helpful. Below you’ll find Oracle Database RU and RUR recommendations and facts. At least some of them … Oracle Database RU and RUR Recommendations and Facts First of all, you will find more information in several blog posts about RU (Release Update) and RUR (Release Update Revision) patches: PSU or BP? Patch Set Update or Bundle Patch? RUR or RU? (May 12, 2017) More Information about RU and…

Differences between PSU / BP and RU / RUR

Since Oracle Database 12.2.0.1 we change our patching model as well, switching from Patch Set Updates (PSU) and Proactive Bundle Patches (BP) to Release Updates (RU) and Release Update Revisions (RUR). But what are actually the differences between PSU / BP and RU / RUR patch bundles? Is there any or is it just a renaming of well known patch bundles? No change on MS Windows First of all, let me say that there won’t be any changes on the Windows platform. If your preferred operating system is MS Windows then stop reading here. On Windows you’ll see exactly the…

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…

Fixes for Adaptive Features are included in Oracle 12.1.0.2 October 2017 BP

Finally … the two most important fixes for Adaptive Features are included in Oracle 12.1.0.2 October 2017 BP (Bundle Patch). I’m absolutely happy about this. Almost all of my customer and many folks outside I’m dealing with on a regular basis had to request and wait for merge patches over and over again. And we all knew – also based on the experience of the Real World Performance Team – that these two patches are so important to stabilize Oracle 12.1.0.2 production systems. You may find this ALERT on MyOracle Support: MOS Note 2289719.1 ALERT: Oracle Recommended Adaptive Feature Configuration…

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…

Applying the first RU for Oracle Database 12.2.0.1

The first RU (Release Update) for Oracle 12.2 is available on most platforms since July 18, 2017. And of course I started applying the first RU for Oracle Database 12.2.0.1 as soon as it got released. See: https://mikedietrichde.com/2017/07/19/first-ru-oracle-12-2-0-1-available/ Download the RU 12.2.0.1.170718 for Linux First of all I downloaded the Database RU 12.2.0.1.170718 Patch 26123830 for Linux from MyOracle Support. To my absolute surprise it was very small compared to previous Proactive Bundle Patches such as the April 2017 one. It has just 40 MB in size (no typo!). Applying the first RU for Oracle Database 12.2.0.1 Then I unzipped…
