Oracle Database 12.2.0.1 and GI are certified on OL8 and RHEL8

Posted on December 14, 2021 by Mike.Dietrich Operating System 4

No worries, this isn’t a blog post from the vault. And I haven’t accidentally published something from the past just today. It is real. Oracle Database 12.2.0.1 and GI are certified on OL8 and RHEL8.

What has been certified?

Thanks to my colleagues and a large customer in the UK, I received an email asking whether I have seen this information already on MOS. I haven’t. I knew that there were discussions but I had no actual date for the 12.2.0.1 certification on OL8 on my radar.

So in brief, these Linux 8 releases …

Oracle 12.2.0.1 Support extended with Limited Error Correction Support

There was sort of a rumor already as some customers sent mail to me last week whether we may extend the support period for Oracle 12.2.0.1. And thanks to my friend, Robert Pastijn, who alerted me minutes ago, you can find this information now as well in the single source of truth, MOS Note:742060.1.

I’ve had so many discussions with customers and partners, and also with colleagues in the past weeks and months about the support time frames for Oracle Database 12.2. Now I checked the blog, and I found so many posts about support periods. And I wrote a similar blog post already 1.5 years ago. I think it’s time to summarize all that. And give you some guidance as well about to which release should you upgrade to? Revisited …

Is Oracle Fail Safe 4.2.1 certified with Oracle Database 19c?

Posted on February 12, 2020 by Mike.Dietrich Fail Safe 2

From time to time I get questions regarding the certification of Oracle Fail Safe. And just the other day, a customer asked: Is Oracle Fail Safe 4.2.1 certified with Oracle Database 19c? I briefly browsed my blog posts about Oracle Fail Safe from the past, and even though I mentioned that the certification for 4.2.1 on Oracle 12.2.0.1 may apply to later versions, I never updated it.

Is Oracle Fail Safe 4.2.1 certified with Oracle Database 19c?

Yes, it is. But you may want to know where you can read and find this information.

Oracle 12.2 and higher: Set _cursor_obsolete_threshold to old default

Posted on September 11, 2018 by Mike.Dietrich Parameters 18

Sometimes development groups change default parameter settings because it fits well for a specific feature. This has happened with _cursor_obsolete_threshold in Oracle Database 12.2. But there’s now an official recommendation for Oracle 12.2 and higher: Set _cursor_obsolete_threshold to old default.

What is _cursor_obsolete_threshold?

First of all, this is obviously an underscore parameter. And usually the policy is: Don’t change underscore parameters unless either you clearly understand what you are changing. Or unless Oracle Support (or another Oracle authority) advises you to do.

DBMS_OPTIM_BUNDLE Package in Oracle 12.2 and 18c

Posted on March 8, 2018 by Mike.Dietrich Optimizer 13

Yes, I did blog about the DBMS_OPTIM_BUNDLE package in earlier Oracle releases before. And I thought (and it was documented this way) that it will disappear in Oracle 12.2 and newer. But in fact you’ll find the DBMS_OPTIM_BUNDLE package in Oracle 12.2 and 18c. Most likely …

This is a very interesting case and you may see also my previous blog posts:

Cloning a PDB from Oracle 12.1 to Oracle 12.2

Posted on November 29, 2017 by Mike.Dietrich Single-/Multitenant 6

Is cloning a PDB from Oracle 12.1 to Oracle 12.2 possible?

A colleague raised this question recently. And a customer did ask me the same question a few days before at a user group conference. There are several ways to move a PDB from Oracle 12.1. to 12.2. But the documentation does not say explicitly if you can do a cloning operation between Oracle 12.1 and 12.2.

It’s November. November is DOAG time. Time really flies. And the German Oracle User Group Conference till kick off in a bit more than a week from now on.

Differences between PSU / BP and RU / RUR

Posted on October 24, 2017 by Mike.Dietrich Patch Recommendation 26

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 …

Lost AWR snapshots reappear again in Oracle 12.2 in Multitenant

Posted on September 4, 2017 by Mike.Dietrich AWR Single-/Multitenant 0

Lost AWR snapshots reappear again in Oracle 12.2 in Multitenant What a strange topic. And I thought I never will blog about this. But as I have received the same question for the third time today, I think there’s a bit clarification needed. Lost AWR snapshots reappear in Oracle 12.2 in Multitenant pluggable databases.

Magically …

Lost AWR snapshots reappear again in Oracle 12.2 in Multitenant

In a non-CDB database you have your local AWR data stored in the SYSAUX tablespace. Whenever you create an AWR snapshot:

exec dbms_workload_repository.create_snapshot;

You can query and of course evaluate it afterwards:

select con_id, snap_id, snap_level, to_char(begin_interval_time, 'dd/mm/yy hh24:mi:ss') BEGIN
from CDB_HIST_SNAPSHOT order by

Fallback Strategy: Flashback Pluggable Database

Posted on August 30, 2017 by Mike.Dietrich Fallback Single-/Multitenant 7

Since Oracle Database 12.2 an important feature works now for pluggable databases as a Fallback Strategy: Flashback Pluggable Database in Oracle 12.2. This was missing in Oracle Database 12.1.

Actually I missed this feature a lot as I use “Flashback” almost everyday. And you could only rewind the entire deployment with a FLASHBACK DATABASE command.

Fallback Strategy: Flashback Pluggable Database

Fallback Strategy: Flashback Pluggable Database in Oracle 12.2 Actually having the possibility to flashback a pluggable database without effecting the other PDBs is really important. Did you ever want to try out what happens if you TRUNCATE TABLE SYS.PROPS$? Give it a try – but set a …

The Oracle Optimizer Statistics Advisor in Oracle Database 12.2.0.1 is something I planned to write about for quite a while. Roy and I include this topic in the New Features section in our Upgrade / Migrate / Consolidate to Oracle Database 12.2 slide deck for some time.

My thoughts about the new Oracle Database Release Schedule

Posted on August 10, 2017 by Mike.Dietrich Release Schedule 26

Changes to a well-known release model mean a lot. I will give you some of my thoughts about the new Oracle Database release schedule.

My thoughts about the new Oracle Database Release Schedule

What are we changing?

In my own words we basically rename the patch sets and name them what they were since years: Full releases. This means, Oracle Database 12.2.0.2 will be Oracle 18. And Oracle 12.2.0.3 will be Oracle 19. And so on.

Therefore there won’t be any Oracle 12.2.0.2 anymore – and obviously no Oracle 13.1 followed by Oracle 13.2.

In addition we change from Proactive Bundle Patches (BP) to Release Updates (RU)…

Having fun with PDB LOCKDOWN PROFILES

Posted on January 17, 2017 by Mike.Dietrich Single-/Multitenant 9

In Oracle Database 12.2 (available in the Oracle DBaaS Cloud) there’s a new functionality called “PDB LOCKDOWN PROFILES“. Actually the parameter came already in undocumented and not functional in Oracle Database 12.1.0.2 (see here).

PDB Lockdown Profiles

PDB Lockdown Profiles are meant as a granular way to restrict or enable access – mostly under the aspect of using the database in a highly shared environment but requiring security. The idea is to embed restrictions on-top of a grant, i.e. taking away certain things. As an example you could allow a user logged into a certain PDB …
