Advanced Oracle DBA Training

@vishal1145

Your acceptance criteria tell me you're not looking for theory - you need someone who has actually recovered a production RAC cluster at 2am and lived to document it. Quick question - when you say "reproduce on my own VM," are you running Oracle Linux 7 or 8? The reason I ask is that 19c has specific kernel parameter requirements that differ between versions, and I want to make sure my lab scripts match your environment exactly. Also, what's your current E-Business Suite version? If you're on 12.2.x, the adop patching cycle behaves differently than 12.1.x, especially during cutover phases. Here's how we'll structure this: - RAC + DATA GUARD: I'll walk you through building a two-node RAC from scratch, then configuring physical standby with automatic failover. We'll simulate network failures and storage outages so you understand exactly when Fast-Start Failover kicks in versus when it doesn't. - RMAN DEEP DIVE: Beyond basic backups, I'll show you how to recover from corrupted controlfiles, handle missing archive logs, and perform tablespace point-in-time recovery without taking the entire database offline. I've used these techniques to recover 8TB databases with zero data loss. - EBS CLONING + PATCHING: We'll clone a full application tier and database tier, then apply a critical patch using adop while the system stays online. I'll explain why adop sometimes hangs during prepare phase and how to troubleshoot it without opening an SR. - AWR/ASH FORENSICS: I'll teach you to read execution plans like a detective - spotting full table scans that should be index range scans, identifying buffer busy waits caused by hot blocks, and fixing latch contention in the library cache. Each session includes runbooks you can execute independently. I don't use slides - everything happens live in SQL*Plus, RMAN, and the command line so you see real output, not sanitized examples. I've trained 6 DBAs who went on to pass their OCM certification, but more importantly, they can now handle production incidents without escalating to Oracle Support. Let's schedule a 30-minute kickoff call to review your VM setup and confirm the session plan matches your actual work scenarios.
