Unplug a 12.2.0.1 PDB and plugin into 18c in the Cloud

There’s been silence for a while – but today I’d like to show you how to unplug a 12.2.0.1 PDB and plugin into 18c in the Cloud. I’m doing this exercise because I’ve seen questions already. And I was curious if it works as I’d expect it. Unplug a 12.2.0.1 PDB and plugin into 18c in the Cloud As usual I will use our hands-on lab environment – and a freshly deployed 18c OCI-Classic instance (formerly known as DBCS formerly known as DBaaS). It is a Single Tenant environment with one PDB. If you need for information about how to…

DBMS_OPTIM_BUNDLE Package in Oracle 12.2 and 18c

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: DBMS_OPTIM_BUNDLE – only available in Oracle 12.1.0.2 – or not? Fixes for Adaptive Features are included in Oracle 12.1.0.2 October 2017 BP Package Differences between Oracle 11.2.0.4 and 12.1.0.2? DBMS_OPTIM_BUNDLE Package in Oracle 12.2 and 18c First of…

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…

Don’t drop the AUDSYS user before upgrading

This is a very interesting case Martin Berger sent to me a week ago. A colleague and him were basically wondering if they should follow the advice in the Oracle 12.2 upgrade guide and drop the AUDSYS user, or if they better don’t drop the AUDSYS user before upgrading. What is AUDSYS meant for? In short, it is the auditing user schema for Oracle 12c and especially Unified Auditing. You’ll find a bit more information regarding Unified Auditing on this blog: Unified Auditing – is it ON or OFF in Oracle 12.1.0.2? Unified Auditing – is it ON or OFF…

DBCA 12.2 does not update /etc/oratab in GI / RAC

Interesting things happen. And I learned (credits to Arun Gupta and others) that there is a change in Oracle Database 12.2 environments I wasn’t aware: The DBCA 12.2 does not update /etc/oratab in GI / RAC environments. Let me give you some extra information and hints on this topic as it may cause some strange situations. DBCA 12.2 does not update /etc/oratab in GI / RAC Arun Gupta commented on the blog: Another case in point. DBCA fails to update the /etc/oratab file in 12.2 when a database is created. There is no documentation of this behavior. So, I opened…

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…

Create Multitenant databases with DBCA – Things to Know

When you create Multitenant databases with DBCA there are some Things to Know. And in Oracle Database 12.2.0.1’s Database Creation Assistant (DBCA) there is a common pitfall in the “Options” screen. It was grayed out in the previous release but when you choose to create a “custom” database you can select the options/components now. Be careful … Previous posts I did blog several times about the DBCA already: Always create databases as customer databases Use your own templates in DBCA when you create databases Does DBCA execute datapatch in Oracle Database 12.2? Create Container databases with less options And there…

Is “imp” still supported in Oracle Database 12.2?

Good question we receive quite often: Is “imp” still supported in Oracle Database 12.2? For clarification: I don’t talk about “impdp” but about old “imp” (import). And yes, it is still supported in Oracle 12.2. The old “exp” got desupported with Oracle Database 11.1.0.6 – but “imp” is still supported, even in Oracle Database 12.2.0.x. You should be able to import your old dumps into the newest release of the database and migrate even VERY old releases directly to Oracle Database 12.2. Actually, the biggest step upwards we’ve heard about a year ago was an exp from Oracle V5 and…
