There’s a new and improved version of the preupgrade.jar (build 5 – May 2017) available for download from MyOracle Support:

The same note will get you access also to the most recent builds of preupgrd.sql for upgrades to Oracle Database 12.1 and utlu112i.sql for the unlikely event you’ll have to upgrade a database to Oracle 11.2.0.4.

Please always exchange the version getting installed by default with the version we offer via MOS Note:884522.1 as the downloadable version is usually much newer and improved over the one getting deployed …

Client Certification for Oracle Database 12.1.0.2/12.2.0.1

Posted on February 17, 2017 by Oracle Database 12.2.0.1 4

I’ve received a question about client certification for Oracle Database 12.2.0.1 the other day.
And this reminded me on this very helpful MOS Note:

It spans the client interoperability back to the Oracle 9.2 days and is a very helpful resource.

Client Certification Oracle Database

And don’t forget that sometimes client software may need a patch as well. A customer I exchange emails with on a regular basis just upgraded the Database server to Oracle Database 12.1.0.2 and saw several strange errors with the JDBC client despite the fact that they …

Restarting a failed Database Upgrade with DBUA 12.2

Posted on January 25, 2017 by catctl.pl DBUA Oracle Database 12.2.0.1 27

In my previous blog post I did showcase how to restart a failed database upgrade on the command line before Oracle Database 12c, with Oracle Database 12.1.0.x and with the new Oracle Database 12.2.0.x:

Restarting a failed Database Upgrade with catctl.pl

Here I’d like to show the new capability of the Database Upgrade Assistant (DBUA) to restart an upgrade, a functionality the DBUA was missing until now. Please note that you can always go back to the command line, no matter in which version you have used the DBUA.

I won’t describe an upgrade with the DBUA in this …

Default Changes SPFILE Parameters – Oracle 12.2

Posted on January 18, 2017 by Oracle Database 12.2.0.1 Parameters 9

This is the 4th posting in my series about init.ora/SPFILE parameters in Oracle Database 12.2.0.1.

Roy and I did a comparison between default parameter settings in Oracle Database 11.2.0.4 vs Oracle Database 12.1.0.2 vs Oracle Database 12.2.0.1. And some changes are quite interesting – of course the memory driven parameters are left out in this list.

Color RED marks a change between releases.

Having fun with PDB LOCKDOWN PROFILES

Posted on January 17, 2017 by 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 …

New PREUPGRADE.JAR is available – MOS 884522.1

Posted on November 24, 2016 by Oracle Database 12.2.0.1 Upgrade / Migration 0

As promised – and thanks to everybody from the Database Upgrade Development Team – the new preupgrade.jar for Oracle Database 12.2 is available:

And of course the previous preupgrd.sql with the package utlupkkg.sql and the old utlu112i.sql for upgrade to Oracle 11.2.0.4 (which I wouldn’t do anymore) are available as well.

New Preupgrd.sql - MOS Note 884522.1

Please ALWAYS use the version downloaded from this MOS note as this version is much newer and better than the version getting shipped due to code freeze dates. And you will recognize that the new preupgrade.jar is now identical …

SPFILE Parameter: max_pdbs – a must for Single Tenant

Posted on November 14, 2016 by Parameters Single-/Multitenant 4

Sometimes my job has a aspect making me smile at the end of the day 😉

I sat together with Johannes Ahrends during a talk at the OUGN Conference on the boat from Oslo towards Kiel. And we were discussing afterwards why there’s no official way to limit the number of PDBs which will be essential for customers wanting to go the Single Tenant track. I had my Hands-On environment up and we played a bit in the break recognizing that a constraint on CONTAINER$ won’t be the correct solution as unplug/plug operations leave leftovers in it unless you …
