What are the best practices? And which special features can you expect in the various cloud deployments? We assume you have on-prem …

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 – Performance Improvements in Oracle 12.1.0.2

Unified Auditing got introduced in Oracle Database 12.1.

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 …
