Binary patching is slow because of the inventory

The headline of this blog post may sound a bit cryptic: Binary patching is slow because of the inventory. But actually this seems to be one of the main causes when your binary patching gets slower and slower with every patch you apply.

The more you patch, the worse it gets

Well, this is a tough headline. But you may have read my blog posts about my quarterly patching experience. It actually started with the July 2021 RU in my 19c environment when I wrote:

At least in my environment, both checks with the

How to speed up your database and GI patching

Several of you mailed me already and commented. And I know that I promised this blog post for weeks, if not longer. So let me try to explain How to speed up your database and GI patching. Since this blog post has a longer history, I’d say far over 6 months, it will be a bit longer than the usual posts. At when I started writing it, I decided to split it up into several pieces to make it more digestible but also to allow easier finding of certain topics. I hope it may help easing some recent patching …

Data Pump Super Patch for Oracle 19.10 and newer

Just a few days we released a Data Pump Super Patch for Oracle 19.10 and newer. “Newer” refers to the fact that once 19.11.0 will be available, this merge patch I’m writing about will be available as well right away (sorry, got delayed a bit). And if you work with Data Pump, you may want to consider this performance patch collection.

Why do you need this patch?

Many customer will know the issue that adding changes with datapatch may take a long time as soon as dpload.sql is involved. And this …

Unified Auditing policies can slow down the upgrade

Unified Auditing policies can slow down the upgradeI posted several blog posts about Unified Auditing in the past. And recently a large customer in the UK alerted me about their upgrades with PDBs from 12.1 to 12.2 taking much longer when Unified Auditing policies were enabled. It looks like as if Unified Auditing policies can slow down the upgrade.

We did some further investigations. See the results below.

Unified Auditing

You find a good number of blog posts explaining how to migrate to Unified Auditing, the performance tweaks in Oracle 12.1.0.2 and some other things:

Unified Auditing – Performance Improvements in Oracle 12.1.0.2

Unified Auditing got introduced in Oracle Database 12.1.

Unified Auditing - Performance Improvements in Oracle 12.1The downsides of the “old” auditing facilities became obvious when too many users had activities or transactions at the same time leading to audit records being written into AUD$. Contention was a typical issue. The same thing happened when too many users tried to login at the same time. Furthermore protecting the auditing information required Database Vault as there was no default protection available.

This – and some other things – should be remedied by Unified Auditing which is available since Oracle Database 12c. It gets enabled in sort of a “mixed …

Different Metrics for SPA (SQL Performance Analyzer)

I’m more the command line type of person. Once I’ve understand what’s going on behind the curtains I certainly switch to the GUI-click-click tools. But in the case of Real Application Testing – even though the support via the OEM GUI is excellent – sometimes I prefer to run my procedures from the command line and check my reports in the browser.

Recently Thomas, a colleague from Oracle ACS Support, and I were asking ourselves about the different comparison metrics for the SQL Performance Analyzer reporting We did scan the documentation but we found only examples but no complete …
