Patching my environments with the January 2023 Bundle Patches

Posted on January 27, 2023 by Mike.Dietrich Patch Recommendation 30

Mid-of January. It’s patching time again. So let me show you the quarterly exercise of Patching my environments with the January 2023 Bundle Patches. Let’s see this time if I will have to remove my Data Pump Bundle Patch and the 19.17.0 MRP2 at first when I patch in-place.

As usual, an important annotation upfront: I patch in-place due to space issues. But in reality, you please patch always out-of-place with a separate home. Please see this blog post about how to apply the RU directly when you provision a new home with OUI…

DBMS_OPTIM_BUNDLE and Out-Of-Place Patching

Well, you see, this is most likely my special DBMS_OPTIM_BUNDLE week. And since I receive quite a number of questions, it may be good to discuss here about DBMS_OPTIM_BUNDLE and Out-Of-Place Patching?

Out-of-place Patching

When you patch out-of-place with a new home – which is clearly our recommendation – you may see another tiny pitfall with DBMS_OPTIM_BUNDLE.

When you check DBA_DIRECTORIES, you will find two directories being related to DBMS_OPTIM_BUNDLE.

SQL> select directory_name, directory_path from dba_directories where directory_name like '%OPTIM%'

DIRECTORY_NAME	     DIRECTORY_PATH
-------------------- --------------------------------------------------
DBMS_OPTIM_LOGDIR    /u01/app/oracle/product/19/cfgtoollogs
DBMS_OPTIM_ADMINDIR  /u01/app/oracle/product/19/rdbms/admin

Patching all my environments with the July 2021 Patch Bundles

Posted on July 27, 2021 by Mike.Dietrich Patch Recommendation 49

It’s patching day again. Hurray! Or not. I realize that at patching day, the 19c bundles are all missing. So wrote this blog post a bit after the usual release day. In my case this will include Oracle 19.12.0 RU and the July 2021 RU for Oracle 12.2.0.1. Please find the details about Patching all my environments with the July 2021 Patch Bundles below.

You may need a one-off for DBMS_OPTIM_BUNDLE in 19.10.0

Posted on February 1, 2021 by Mike.Dietrich Optimizer Patch Recommendation 22

It’s been a while since I blogged about the DBMS_OPTIM_BUNDLE – and to me, the package is still sort of a mystery. 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.

I’m tempted to copy and paste my blog post about DBMS_OPTIM_BUNDLE from February 2019, and exchange only 12.2.0.1 with 19c. But in this case the root cause is different. So this blog post is meant for Oracle 19.3.0 to be precise – in case you miss DBMS_OPTIM_BUNDLE … again … ?!?
