Most of the Oracle world still lives in the data center: installations, quarterly patches, tuning and licensing under control.
Anything but nostalgia: most Oracle databases still run on-premises, on Linux and on IBM Power (AIX). Our craft is keeping them healthy: quarterly Critical Patch Updates, verified RMAN backups, Data Guard standbys, tuning and — the scary chapter — licensing governed before the audit arrives.


CPUs/RUs applied on standbys and switchovers: security without downtime.
19c → 23ai planned with AutoUpgrade and rehearsals: the leap without a net is for trapeze artists only.
AWRs actually read, heavy SQL and waits understood: the database fast over the years.
Options switched on by mistake, virtualization and cores: the map that avoids disputes.
On-prem Oracle plays out on editions (EE with the options, SE2 with its limits), metrics (processor with core factor, NUP with the minimums) and architectures: multitenant (3 free PDBs from 19c/21c+), Data Guard for DR, RMAN for backups, quarterly patching (RU) to industrialize. Virtualization must be handled: Oracle's partitioning policies on VMware require design, not improvisation.
The average ERP runs here: we keep it impeccable.
Database and AIX on the same resilient iron: our double specialty.
Patches and evidence in order for NIS2 and audits.
