Oracle Linux 5 saw the introduction of the oracle-validated RPM (you can see the first version appearing in OEL5.2 here although it also snuck in to later versions of OEL4). This addition to the DBA kit bag is what makes Oracle Linux my favourite OS for installing the Oracle Database. Oracle has always been a great supporter of Linux, since long before most companies considered it an enterprise-class and data-centre-ready operating system. DBAs have never had it so good 🙂īut the change which really made a difference for me was the creation of the oracle-validated RPM in Oracle Linux.

Things are a lot easier these days, with the Oracle Universal Installer (OUI) checking many settings, warning you if they are incorrect and even offering you a script which will automagically fix them. If you were installing products such as ASM, CRS or the more-recent Grid Infrastructure then there would be additional preinstallation requirements sections to crawl through.

You used to have to go through the Oracle Database Preinstallation Requirements section of the documentation in pain-staking detail looking for every little kernel setting, operating system package and security configuration necessary to ensure that your database was in a supportable configuration. Setting up a Unix system ready for use with Oracle used to be a bit of a pain. Using Oracle Preinstall RPM with Red Hat 6
