Attention | The RUR trap!

• You will consume RUs "secretly"

• Stay with RUs!

Simple Example | RU vs RUR

• Example number of fixes• Every RU: 100 new fixes

• Every RUR: 25 new fixes

Type April July October January April

RU 100 200 300 400 500

RUR-1 125 225 325 425

RUR-2 150 250 350

Basic Facts | opatch and datapatch

• opatch• Applies binary files to a home

• Database services must be down• RAC allows rolling patching node-by-node

• opatchauto for RAC environments

• datapatch• Applies SQL changes to a database

• Database must be up

Basic Facts | Patch Inventory

• opatch lsinventory

• Tells you what is installed in your software home

• DBA_REGISTRY_SQLPATCH• View detailing information about SQL patches installed in the database

• DBMS_QOPATCH package provides access to • Patches installed in the Oracle Home
