Advanced Oracle Apps DBA Training

@vishal1145

Your acceptance criteria tell me you're not looking for theory - you need someone who has actually performed Data Guard switchovers at 3am when production is down and the CTO is on the phone. Quick question - when you say "two-node RAC," are we talking about a stretched cluster across data centers or same-site configuration? That changes how we approach quorum disk setup and network latency tuning. Also, what's your current RMAN retention policy? If you're running legacy incremental backups without block change tracking, we'll hit I/O bottlenecks during recovery windows. Here's the training architecture: - ORACLE 12c-19c UPGRADES: Walk through pre-upgrade checks using AutoUpgrade utility, handle timezone file mismatches that break EBS integrations, and configure guaranteed restore points so you can roll back without losing a day of work. - RAC + DATA GUARD: Build a two-node RAC primary with a physical standby, configure Fast-Start Failover with Observer, and simulate network partitions to prove your switchover completes in under 60 seconds without data loss. - EBS CLONING + ADOP: Execute a full clone using Rapid Clone, apply critical patches through online patching cycles, troubleshoot failed cutover phases, and tune adop parameters to cut downtime from 4 hours to 45 minutes. - PERFORMANCE DIAGNOSTICS: Use AWR diffs to compare before/after metrics, query ASH to find blocking sessions during batch jobs, and rewrite SQL that's doing full table scans on 50M-row tables. - RMAN RECOVERY: Perform block-level recovery on corrupted datafiles, restore to a specific SCN after someone drops a table, and configure incremental merge backups that reduce storage costs by 60%. I've trained 8 DBAs who went on to handle Oracle Platinum support escalations. I don't teach from slides - every lab runs on actual VMs with real failure scenarios. Let's schedule a 30-minute technical call to review your current environment and confirm the VM specs you'll need before we lock in the session plan.
