Production DBA Runbooks: Incident Triage & Emergency Response Workflows

A complete collection of production-grade Standard Operating Procedures (SOPs) and emergency runbooks for P1/P2 database incidents: 100% full log emergencies, Out-of-Memory dumps, indexserver crashes, and lock freezes.

Advanced (Senior DBA)Production Runbooks~25 min studyHANA 2.0 (All SPS)

Core Learning Objectives

1.Execute structured P1 incident triage under high-pressure production downtime.
2.Remediate /hana/log 100% full emergencies without restarting the database.
3.Analyze Out-of-Memory (OOM) trace dumps and configure statement memory guardrails.
4.Diagnose indexserver crash-restart loops and persistence replay failures.

Definition & Architectural Rationale

Technical Definition:

Production DBA Runbooks are prescriptive, battle-tested operational procedures outlining exact step-by-step diagnostic queries, OS commands, decision trees, and remediation actions required to resolve critical database incidents.

Why this component exists:

During a production outage costing thousands of dollars per minute, ad-hoc guessing or executing dangerous trial-and-error commands (such as blind database restarts or kill -9) exacerbates data loss and extends recovery times. Structured runbooks standardize response delivery.

Internal Working & Mechanics

Runbook Execution Methodology: 1. Phase 1: Detection & Triage: Fast identification of affected components and SLA severity (P1 vs P2). 2. Phase 2: Diagnostic Evidence Collection: Capturing live active states, trace logs, and OS capacity before taking invasive actions. 3. Phase 3: Root Cause Isolation: Pinpointing the exact offending query, disk mount, or memory allocator. 4. Phase 4: Remediation Action: Executing documented recovery commands (e.g. canceling runaway sessions, growing filesystems, rerouting log backups). 5. Phase 5: Post-Fix Verification: Validating that transactions are processing, ports are listening, and alerts have cleared.

Architectural Flow: The 5-phase incident response cycle ensures that critical diagnostic evidence is captured before remediation is executed, preventing recurring outages.

Production Best Practices & Operational Risks

Mandatory Best Practices

Review daily morning operational checklists every day at 08:00 AM.
Maintain an updated off-host copy of all DBA runbooks accessible during network failures.
