RMAN in Oracle 19c vs 26ai — What Changed??
Every time Oracle releases a major version, DBAs carefully review new SQL features and optimizer changes — and then quietly forget to review backup and recovery changes until something breaks in production. Oracle AI Database 26ai brings some of the most significant RMAN and security changes since the introduction of the Multitenant architecture. Some of… Continue reading

Oracle AI Database 26ai — The Features That Will Change How You Build Applications?
If Blog Post 26 covered what 26ai means for DBAs managing infrastructure, this post is about what it means for the teams building applications on Oracle. The developer experience improvements in 26ai are substantial — JavaScript stored procedures, enhanced vector search with sparse vectors and binary formats, natural language interfaces, AI agent frameworks, and SQL… Continue reading

Oracle 23ai to 26ai — What Actually Changed?
n October 2025, Oracle made an announcement that made most DBAs read the headline twice: Oracle Database 23ai was being renamed Oracle AI Database 26ai. A simple rebranding? Absolutely not. This is Oracle’s most significant database release positioning in years, and the technical changes underneath the name are substantial. As someone who has been tracking… Continue reading

Oracle Performance Tuning in 2025 — Starting With AWR Before Touching Anything Else?
Every Oracle performance engagement I’ve been part of has followed the same pattern when done correctly: start with AWR, form a hypothesis, validate with deeper tools, then act. The engagements that go badly almost always involve someone who acted before they understood — adding an index, changing a parameter, rewriting a query — based on… Continue reading

Oracle Scheduler in 2026— Need to Replacing Cron Jobs?
If you’re still running Oracle-related batch jobs as OS cron jobs or Windows scheduled tasks, you’re missing one of Oracle’s most underused built-in capabilities. Oracle Scheduler (DBMS_SCHEDULER) has been available since Oracle 10g and in 2025 it’s significantly more capable than most DBAs realize. It provides job scheduling, dependency chains, windowed execution, resource integration, logging,… Continue reading

OCI Exadata Database Service vs Base Database Service — Making the Right Choice? But how?
When customers start their Oracle Cloud journey, one of the first decisions they face is which compute platform to run their databases on. OCI offers several options, but the choice most production Oracle shops wrestle with is between Base Database Service (DB System) and Exadata Database Service (ExaDB-D, formerly Exadata Cloud Service). The cost difference… Continue reading

Oracle 23ai SQL Domains — Writing Less Code While Enforcing More Rules
One of the quieter but genuinely useful features in Oracle 23ai is SQL Domains. It doesn’t have the headline appeal of AI Vector Search, but for development teams building new applications on Oracle, it addresses a real and persistent problem: the same validation logic duplicated across dozens of table columns, the same formatting rules re-implemented… Continue reading

Oracle Database Backup to OCI Object Storage — The Complete Guide for 2026
Object Storage is the right destination for Oracle Database backups in OCI environments. It’s dramatically cheaper than Block Volume for backup retention, it’s geographically redundant by default, and it integrates with RMAN through Oracle’s database cloud backup module. But “integrates with RMAN” covers a lot of ground — the configuration details matter, and the defaults… Continue reading

Oracle APEX 24.x on OCI — Building Internal Tools Without Buying More Software
One of the most underappreciated cost-saving opportunities in Oracle shops is APEX. Every Oracle Database license includes APEX at no additional cost. On OCI, Oracle offers APEX Application Development as a managed service where you don’t even manage the database — you just build. I’ve watched teams pay for Retool, internal dashboard tools, and custom-built… Continue reading

ORA-12545 and ORA-12541 — Listener Troubleshooting That Goes Beyond the Basics! Let’s us check!
Every Oracle DBA knows how to check if a listener is running. lsnrctl status. If it’s down, start it. Problem solved, right? In a simple environment, yes. But in 2025, Oracle environments are rarely simple — they involve OCI networking layers, VCNs, Security Groups, firewalls, multiple listeners, RAC scan listeners, and PDB-specific services. The listener… Continue reading
