# Industrial Specification: Recovery Manager

## 1. Technical Definition
A software component within a Transaction Coordinator that manages transaction recovery processes after system failures.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-100% CPU utilization, 1-1000 transactions/second, 0.1-10 seconds recovery latency**. Failure boundary: **CPU utilization &gt;95% sustained for 300 seconds, memory consumption &gt;90% of allocated heap, network latency &gt;500ms for 60 seconds**, Mechanism: **Resource exhaustion leading to thread starvation, memory fragmentation causing garbage collection thrashing, network partition violating CAP theorem consistency guarantees**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Write-ahead log corruption due to disk sector failure at LBA 2048-4095 | 8 | Transaction state inconsistency causing deadlock detection timeout after 30 seconds | Triple modular redundancy with checksum validation using CRC-32 algorithm on log entries |
| Clock skew exceeding 50ms between distributed nodes violating Lamport timestamp ordering | 8 | Two-phase commit protocol blocking at prepare phase for 120 seconds | Hybrid logical clocks with NTP synchronization maintaining &lt;10ms precision across nodes |

- **Caution**: 

### Q: What does the Recovery Manager do in computer manufacturing systems?
**A**: The Recovery Manager is a software component within Transaction Coordinators that automatically manages recovery processes after system failures, ensuring transaction integrity through rollback, redo, and log analysis functions.

### Q: How does the Recovery Manager handle transaction failures?
**A**: It uses four core components: Log Manager tracks transactions, Recovery Analyzer assesses failure impact, Rollback Handler undoes incomplete transactions, and Redo Handler reapplies completed transactions to restore system consistency.

### Q: Why is recovery management important in electronic product manufacturing?
**A**: In computer and optical product manufacturing, system failures during transactions can corrupt production data, disrupt supply chains, and cause financial losses. The Recovery Manager ensures data integrity and minimizes downtime.
