My team mates are really quick. We received an information early this week about a missing or wrong DV check in the preupgrade – and they implemented it within a day or so. The September 2018 version of the improved preupgrade.jar for Oracle 12.2 and 18c is available for download. Improved preupgrade.jar for Oracle 12.2 and 18c What’s new in this version: It adds a recycle bin check when the autofixup for dictionary statistics is run And it updates DV_AUDIT_CLEANUP to 11.2.0.4 Please find the new September versions of: Oracle 12.2.0.1 preupgrade.jar – build 17 There’s issue with “creating directories”…
My team mates worked hard to improve release the new August 2018 preupgrade.jar for upgrades to 18c and 12.2.0.1. You can download both from myOracle Support. New August 2018 preupgrade.jar for upgrades to 18c and 12.2.0.1 As usual, MOS Note: 884522.1 gives you access to the most recent versions of the preupgrade.jar tools (and of course the previous preupgrd.sql and utlu112i.sql scripts). One of the major changes is the inclusion for a check for the XMLCONCAT synonym. Please find the most recent versions here and exchange your current version of preupgrade.jar with the newer ones. –Mike
We read and listen to your comments. And that’s why my team mate Byron has added a new preupgrade.jar and changes to MOS Note:884522.1. One reader commented that MOS Note:884522.1 (How to Download and Run Oracle’s Database Pre-Upgrade Utility) does not explain how to “run” the preupgrade tool even though it mentions this in the note’s title. New preupgrade.jar and changes in MOS Note:884522.1 With MOS Note:884522.1 you can download always the most recent versions of the Oracle 18c and 12.2 preupgrade.jar tools, of the Oracle 12.1.0.2 preupgrd.sql and utluppkg.sql. And you’ll even find the last utlu112i.sql for upgrades to Oracle…
Most of you may not care about the checks our Pre Upgrade Check tool preupgrade.jar does. But some may. Especially in cases where you plan to run a command line upgrade unattended via a script. Therefore this List of PREUPGRADE checks executed by preupgrade.jar may help you. List of PREUPGRADE checks executed by preupgrade.jar As a result of a joint initiative between our Upgrade Development team and the Support group dealing with upgrade-related SRs we released this MOS Note: MOS Note: 2380601.1 Database Preupgrade tool check list Purpose of the new MOS note is to give you a complete list…

There’s a new and improved version of the preupgrade.jar (build 5 – May 2017) available for download from MyOracle Support: MOS Note:884522.1: How to Download and Run Oracle’s Database Pre-Upgrade Utility 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 with the…
We discussed an interesting upgrade case last week together with our upgrade colleagues in Support – and learned the double-hop (or triple-hop) upgrade case is not described in the documentation somewhere. What is a multiple-hop upgrade? Actually this describes the case where somebody can’t upgrade directly and has to do several upgrades in a sequence to reach the targeted release. For example, you start of with an Oracle 10.2.0.3 database – and your targeted release is Oracle 12.2.0.1 . A direct upgrade is not possible. I would opt now for Data Pump or TTS as you could jump directly. But…
As promised – and thanks to everybody from the Database Upgrade Development Team – the new preupgrade.jar for Oracle Database 12.2 is available: MOS Note:884522.1 – Download and Run Oracle’s Database Pre-Upgrade Utility 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. 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…
As I wrote the other day, OOW 2018 is not too far away anymore. And if you’d like to see something really new, something which can really really ease your database upgrades in the near future, then you may visit our first talk right on Monday morning at OOW2018: The new AutoUpgrade for the Oracle Database. What is this talk all about? First of all, let me emphasize that we don’t do marketing. We would like to introduce you to a brand new tool we’ll currently have in beta operation at selected customers. And which we’ll release in the new…
Protection for issues during upgrade In this part you’ll use two techniques to protect your database for issues happening during the upgrade. Or simply, if you’d like to test multiple times. You will evaluate two options: Partial Offline Backups and Guaranteed Restore Points. 1. Partial Offline Backup A partial offline backup is used for protection against failures during the upgrade or for testing purposes to avoid the restoration of an entire database environment. You can change the COMPATIBLE parameter if you want with this technique. But don’t do it in the lab now as you’ll use two techniques in parallel….
If you are a regular user of ORAchk and/or EXAchk, you should download the most recent and newest version as Oracle ORAchk and EXAchk Version 18.3.0 are released now.

Automatic start from TFA install Oracle Trace File Analyzer root installations on Linux or Solaris on non-engineered systems will automatically setup and run the ORAchk daemon.The…
Thanks to my team mates, Cindy and Hector, who alerted me on this newly detected issue. When your database has been upgraded from release to release, it could happen that a public synonym XMLCONCAT exists. And before you upgrade to Oracle 12.2.01 or Oracle 18c you must drop this public synonym to avoid upgrade errors. Drop public synonym XMLCONCAT prior to upgrade The public synonym XMLCONCAT in pre-9.2.0.2 Oracle databases pointed to a PL/SQL function of the same name. In 9.2.0.2, this PL/SQL function was changed to a C function.The public synonym was no longer needed nor pointing to a…
As Oracle Database 18c is now available on Linux on premises, I blogged about the installation already. And the next logical step is the Oracle Database 18.3.0 Upgrade on premises. In this case I will show an upgrade on the command line from Oracle 11.2.0.4 to Oracle 18.3.0. A DBUA upgrade will follow in a separate blog post later. Oracle Database 18.3.0 Upgrade on premises Before you can start with the upgrade, you may download the software first, and then install it: Oracle Database 18.3.0 on premises is available on Linux Oracle Database 18.3.0 Installation on premises If you read…
In this part of the Hands-On Lab you will now unplug an Oracle 12.1.0.2 pluggable database (PDB) from CDB1 and plug it into CDB2 including all the necessary steps. Index 1.

I’m currently refreshing our Hands-On Lab and will exchange Oracle 12.2.0.1 with Oracle 18.2.0. This blog post series is about how to Upgrade to Oracle 12.2.0.1 to Oracle Database 18c on-premises. There are other blog posts available you may use by yourself if you plan to refresh the lab by yourself until we uploaded a newer version. And it’s actually a good exercise. Deinstalling Oracle Database 12.2.0.1 Installing Oracle Database 18.1.0 Patching Oracle 18.1.0 to 18.2.0 Upgrade Oracle 12.2.0.1 to Oracle Database 18c on-premises For Multitenant upgrades from Oracle 12.1.0.2 to Oracle 12.2.0.1 you may read this: Upgrade Everything at…
Underscore parameters are a wonderful thing in Oracle. They are treated like a secret. But you can view them of course. Everybody can. Make a guess how many underscore parameters exist in Oracle 12.2.0.1.0. You’ll find the answer at the end of this blog post. But why should you remove underscore parameters not only before you upgrade? I’d like to explain below why underscores, especially too many of them, may cause a lot of trouble. Therefore, housekeeping is very important. Remove Underscore Parameters not only before you upgrade This is from a recent upgrade from Oracle 12.1.0.2 to Oracle 12.2.0.1…
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…
This is a topic which doesn’t come up very often. But if it does come up from time to time, and the documentation may give you advice – but as I realized – it does not always give the best advice. When you have to do multiple hops – which should be your intermediate release? I posted something about this topic a while back: Multiple hop upgrades? Execute the matching preupgrade scripts for each hop What are Multiple Hops? We speak of multiple hops in relation to database upgrades when your source release does not allow you to upgrade directly…
This question comes up very often: What is the minimum supported version for database upgrades? Or a question I received today: “I have an Oracle 10.2.0.4 database, can I upgrade directly to Oracle 11.2.0.4?” Usually I have to dig into my old slides from the past to give a definite answer. And of course, the Database Upgrade Guide of each version has the same information somewhere as well. Therefore I’d like to summarize the releases supported for direct database upgrades since Oracle 11.2.0.4 below. Upgrade? When I speak about database upgrades, I mean you’ll use either the command line upgrade…
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. Cloning a PDB from Oracle 12.1 to Oracle 12.2 You can clone a non-CDB and make it a PDB but you need to run noncdb_to_pdb.sql afterwards. When I wrote this blog post, Oracle…
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…
A customer of mine hit an issue recently when upgrading to Oracle Database 12.2.0.1. They did everything correctly but received a ton of issues from the Data Guard Broker. A rule says: When you upgrade, disable the Data Guard Broker. But I can’t blame the customer as this “rule” is well hidden in the documentation. When you upgrade, disable the Data Guard Broker First of all, the Data Guard Broker is required if you would like to administer your databases in Oracle Cloud Control. Otherwise you can’t switchover or failover within Enterprise Manager. But once you approach a database upgrade…
