SERVICE / Oracle HA

Oracle RAC & Data Guard production expertise.

Architecture is only useful when it survives real workload, incidents and recovery events. We help teams operate and improve Oracle RAC and Data Guard with evidence-driven diagnostics and clear ownership.

Keep availability decisions tied to evidence.

RAC workload & service diagnostics

Separate local database pressure, global-cache behavior, service placement and application connection patterns before changing the cluster.

Data Guard readiness

Review transport, apply, lag, protection mode, broker/operating procedures and the real path to a controlled role transition.

Performance investigation

Use workload history, waits, SQL, memory, I/O and interconnect evidence to isolate the actual constraint.

Incident isolation

Distinguish database symptoms from application, network, listener, storage or operating-system causes so remediation lands in the right layer.

RAC and Data Guard decisions are shaped by failure domains, recovery objectives, network/storage characteristics, operational maturity and the consequences of planned or unplanned role changes.
