Choose your desired time zone version (DST) upgrade

This morning I received a very reasonable question from a customer who has a time zone mismatch between source and target database. And he wants to transport into a PDB on Exadata. Even though, this sounds trivial at first sight, unfortunately it isn’t. But a bug fix done recently for a German automotive customer is very handy here. So let me show you how you can Choose your desired time zone version (DST) upgrade.

Patching process changes with MRPs

Posted on May 22, 2023 by Mike.Dietrich Patch Recommendation 10

I blogged about the Monthly Recommended Patches (MRP) several times before. And due to the feedback you and we had given, a few things got changed. The main change is from having the MRP bundled as a system patch making opatchauto a requirement. See below what Patching process changes with MRPs were implemented recently.

Christian Pfundtner pointed me to the fact that my old blog post about the Statistics Advisor from 2017 may not be up to date anymore. And he further pointed out that some of his clients still suffer from issues with the tool. Hence, let me refresh the topic with Oracle Optimizer Statistics Advisor in Oracle 19c. And thanks to Christian for the pointers.

I thought I could relax this week using my leftover vacation days from 2022. But this issue is triggering me since some of you mailed me already.

Patching all my environments with the October 2022 Bundle Patches

Posted on November 9, 2022 by Mike.Dietrich Patch Recommendation 56

Oh yes, it is patching time (again). And this time I somehow missed the slot since the quarterly critical patch updates got released right during Oracle Cloud World. Since I didn’t want to stretch the hotel WiFi too much – and since I wouldn’t have had enough time to install and write-up this blog post, I do it now with a week of delay.

My calendar has no error or NLS conversion issue – I was just way to busy the past two months with seminars. But today a colleague asked me whether my 21.4 install reports a 21.3 Build Label in the trace files.

AutoUpgrade may run into a timeout when GI is lower than 19.10.0

Posted on June 21, 2021 by Mike.Dietrich ASM / RAC / GI Patch Recommendation 9

The other day I received a question from a colleague about the risk of having GI and database both not being on the same RU. And a long while ago I blogged about it. We recommend that you keep it in synch. But you don’t have to. At the same time I received a wish from Ernst Leber to post something on the blog he and his colleague had trouble with when upgrading to 19c in a RAC environment. AutoUpgrade hung. But he titled his email with “not an AutoUpgrade problem!”. Still I agree, it is worth to write …

Workaround for sdoloadj.sql errors with Datapatch in 19.9.0 and 19.10.0

Posted on March 2, 2021 by Mike.Dietrich Flaws and Pitfalls 6

The other week a customer from my hometown alerted me about an issue they saw when applying the 19.9.0 RU. A long sequence of errors in the datapatch run, all of them signaled from sdoloadj.sql. They opened an SR. And Support had an – understandable – recommendation the customer didn’t want to implement: Install JAVAVM. But thanks to my PM mate, Hans Viehmann (Mr Spatial), here is a simple Workaround for sdoloadj.sql errors with Datapatch in 19.9.0 and 19.10.0. And it may even apply to later releases, too.

Ideally you can least and enable or disable behavior changing optimizer fixes per RU. And in Oracle 19.10.0, you will find a new surprise. So You may need a one-off for DBMS_OPTIM_BUNDLE in 19.10.0.
