Issues with seed databases, patch bundles and OJVM in 19c

I really rely on people telling me about issues they saw. And in this case, it happened twice within a few days. At OOW London, a customer came after my talk and told me about invalid objects and an incredible long recompilation time. In fact, he had to apply an OJVM patch in order to solve this. When I returned home, Jure commented on the blog about a very similar issue. I spent some time on the weekend to check it out. And I realized: There are issues with prebuilt seed databases and OJVM in 19c.

Oracle Database 20c – The first CDB-only release

Do you remember? At OOW 2019 in San Francisco, we announced that Oracle Database 20c will be the first CDB-only database release. But at this time we didn’t present this in written form. We told you, once the Oracle Database 20c documentation is available, you will see it. Oracle Database 20c – The first CDB-only release.

Oracle Database 20c – Documentation and Cloud availability

Yesterday at OOW London, my dear colleague from Oracle Italy, Roberto Zampese told me that our EVP Juan Loiza has announced the availability of Oracle 20c within days. And this morning, Daniel told me that it you can provision 20c instances in our OCI Cloud already. In addition, the documentation is available already, too.

First of all, find the Oracle Database 20c documentation here:

And as usual, the first thing I usually do, is browsing through the New Features Guide.

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

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.

APEX is invalid after upgrading to 12.2 – ORA-20001

We are running the AutoUpgrade-for-RAC beta test since last week. And the first issue one customer encountered … is neither an AutoUpgrade nor a RAC issue. It has to do with APEX and SPATIAL, and missing grants. APEX is invalid after upgrading to 12.2 – ORA-20001

Be aware when you use _ORACLE_SCRIPT in scripts

Recently I came across this when I gave a Multitenant workshop at a German customer. As part of the workshop I explained the _ORACLE_SCRIPT statements you will find in almost all scripts in ?/rdbms/admin. And one of the DBAs gave me a bright smile. He mentioned: “We use it already everywhere to avoid strange errors”. But be aware when you use _ORACLE_SCRIPT in scripts. I will explain, why this can be dangerous.

Oracle Multitenant: Be aware of the silent COMPATIBLE change

This topic is included in our Multitenant slides for a long time. But whenever I want to point somebody to the blog post, I realize that it’s not on the blog yet.

OOW London 2020 – Upgrade Talk and more

Do you need to license Java for AutoUpgrade?

Actually this question came up internally. I did have no doubt that you don’t have to license Java in order to use AutoUpgrade. But a colleague had such doubts. So let’s clarify: Do you need to license Java for AutoUpgrade?

Upgrade PDBs with RELOCATE – How does it work?

Today Roy and I received a question from a colleague about the RELOCATE feature in Multitenant. And I’d like to shed some light and this topic a bit more. Upgrade PDBs with RELOCATE – How does it work?

Upgrade PDBs with RELOCATE - How does it work?

RELOCATE and UPGRADE?

At first, it looks very promising to me. RELOCATE uses the HOT CLONE functionality of Multitenant but then relocates the PDB from one to another CDB. You need to fulfill a few important requirements, for instance:

  • Local Undo must be enabled in both CDBs
    • This limits the technique to at least Oracle

Can you have more than 1 PDB with Standard Edition 2 (SE2)?

When we announced the 3-PDB-Support with Oracle Database 19c onward at OpenWorld 2019, I was very excited. According to the license documentation, this applies to Standard Edition 2 (SE2) as well. But does it work? Can you have more than 1 PDB with Standard Edition 2 (SE2)?

Do we offer patched Gold Images already?

Internally we can use a Gold Image service at Oracle. I can download a zip with 19.6.0 included. But externally for you as customers, the download of 19.6.0 required that you download 19.3.0 at first, then apply 19.6.0 on top of it. But a day ago, a tweet by my Belgium friend Philippe Fierens caught my attention. Do we offer patched Gold Images already?

Do you need to apply OJVM patches to Grid Infrastructure?

A quick MOS check

Well, you’d assume this is something MOS does give you an answer within fractions of a second. But nope. I found a lot but unfortunately not what I was looking for. What I found instead where community discussions where applying OJVM patches to a 12.1.0.2 GI installation corrupted the inventory. Hence, there seems to be some …

Do you need STARTUP UPGRADE for OJVM?

Actually I carry around this topic with me since the October 2019 workshop in Dubai. We’ve had one of these OJVM Patching discussions I’d like to escape usually. Anyhow, during this session, it dawned me that the STARTUP UPGRADE requirement in the OJVM readme may be not correct anymore. So the question will be: Do you need STARTUP UPGRADE for OJVM?

Patching all my environments with the January 2020 Patch Bundles

I was traveling last week and had not enough time to download and apply the January 2020 Release Updates and PSUs. Yes, I’m one week late. But nevertheless, I’d like to check whether patching my databases with the January 2020 RUs will work fine.

Canada rocks – and is really cold in winter

Last week I’ve had one of those travel weeks where I accumulate many working hours already by flying and having layovers and delays at lovely airports. Plus of course, I work in addition and deliver full-day workshops. And see customers. Still, I won’t complain as I like my job a lot. Especially meeting with customers and discussing various upgrade and migration topics can be really challenging sometimes. And I can confess, Canada rocks – and is really cold in winter. Seriously …

GI Patch 28553832 may be needed before you upgrade to 19c

Thanks to my colleague Sebastian Alasino who works in the MAA team out of the UK. Sebas highlighted this issue to. And I’d like to share it with you when you attempt to upgrade Grid Infrastructure to Oracle 19c. If you have the Docker RPM  installed and you were lazy on patching, then GI Patch 28553832 may be needed before you upgrade to 19c.

“My” best records for 2019 – and some other thoughts

Oh well, the older I get the faster years seem to pass by. I think this is natural. And a while ago I read a very good and reasonable explanation for this. But I can’t complain actually. Life is not boring at all – and I learn something new almost every day. As you know, one of the main reasons for this blog is to share parts of my learning experience with you, the good, the bad – and the patches 🙂

But there’s a life apart from Oracle (at least sometimes). And as some of you may know, music …

Mobiliar Insurance consolidates over 350 PDBs to new Exadatas

The year is almost over and many of you will take off in your well-deserved holidays. At this point it’s not time yet for a 2019 summary or my “Best Records of 2019” list, but to highlight a great success story from Swiss Mobiliar Insurance’s Oracle team.

ORA-1722 when upgrading to 19.4.0 or 19.5.0 on Windows

Oh boy – I try to avoid blogging about errors on a specific platform. But as this topic was brought to my attention now 3x in 2 weeks, I think I’ll send it out. And I hope you won’t hit this ORA-1722 when upgrading to 19.4.0 or 19.5.0 on Windows.
