|
|
---
|
|
|
|
## SCENARIO OVERVIEW
|
|
|
|

|
|
**Date:** [Enter date in ISO 8601 format: YYYY-MM-DD]
|
|
**Incident Classification:** Medium (Transaction Timeout)
|
|
**Participants:** Financial Operations Department, Technical Department, Reserve System Team
|

|
|
|
## STEP 1: TIMEOUT DETECTION (T+0 minutes)
|
|
|
|
### 1.1 Initial Timeout Detection
|
|
- **Time:** 16:45 UTC
|
|
- **Detection Method:** Transaction processing system timeout
|
|
- **Timeout Details:**
|
|
- Transaction ID: TXN-2024-001234
|
|
- Transaction Type: Reserve Conversion (XAU to Digital Asset)
|
|
- Timeout Duration: 30 seconds (exceeded)
|
|
- Transaction Status: Timed out
|
|
- System Response: Transaction rolled back
|
|
- **System Response:** Transaction automatically rolled back, error logged
|
|
|
|
### 1.2 Error Analysis
|
|
- **Time:** 16:46 UTC (1 minute after detection)
|
|
- **Analysis:**
|
|
- Timeout cause: External API delay (XAU price feed)
|
|
- Transaction state: Rolled back (no partial execution)
|
|
- Data integrity: Maintained
|
|
- User notification: Required
|
|
- Retry: Possible after investigation
|
|
|
|

|
|
|
|
## STEP 2: ERROR HANDLING (T+2 minutes)
|
|
|
|
### 2.1 Transaction Rollback
|
|
- **Time:** 16:47 UTC (2 minutes after detection)
|
|
- **Rollback Actions:**
|
|
1. Verify transaction rollback
|
|
2. Check data integrity
|
|
3. Verify no partial execution
|
|
4. Log transaction details
|
|
5. Preserve transaction context
|
|
- **Rollback Status:**
|
|
- Transaction: Fully rolled back
|
|
- Data integrity: Verified
|
|
- No partial execution: Confirmed
|
|
- Transaction log: Complete
|
|
|
|
### 2.2 User Notification
|
|
- **Time:** 16:48 UTC
|
|
- **Notification Method:** Application notification and email
|
|
- **Notification Content:**
|
|
- Transaction timeout occurred
|
|
- Transaction rolled back (no charges)
|
|
- Reason: External service delay
|
|
- Action: Retry available
|
|
- Support: Contact information provided
|
|

|
|
## STEP 3: ROOT CAUSE ANALYSIS (T+5 minutes)
|
|
|
|
### 3.1 Investigation
|
|
- **Time:** 16:50 UTC (5 minutes after detection)
|
|
- **Investigation Actions:**
|
|
1. Review transaction logs
|
|
2. Check external API status
|
|
3. Analyze timeout cause
|
|
4. Evaluate system performance
|
|
5. Check network connectivity
|
|
- **Findings:**
|
|
- External API: XAU price feed delayed (15 seconds)
|
|
- Transaction processing: Normal
|
|
- Network connectivity: Stable
|
|
- System performance: Normal
|
|
- Root cause: External service delay
|
|
|
|
### 3.2 Resolution Strategy
|
|
- **Time:** 16:52 UTC
|
|
- **Resolution:**
|
|
1. External API: Status normal (temporary delay resolved)
|
|
2. Transaction: Can be retried
|
|
3. User: Notified and can retry
|
|
4. System: Monitoring enhanced
|
|
- **Status:**
|
|
- External API: Operational
|
|
- Transaction: Ready for retry
|
|
- User: Notified
|
|
- System: Enhanced monitoring
|
|
|

|
|
|
|
## STEP 4: TRANSACTION RETRY (T+10 minutes)
|
|
|
|
### 4.1 User Retry
|
|
- **Time:** 16:55 UTC (10 minutes after detection)
|
|
- **User Actions:**
|
|
1. Review notification
|
|
2. Understand timeout cause
|
|
3. Retry transaction
|
|
4. Monitor transaction status
|
|
- **Retry:**
|
|
- Transaction: Retried
|
|
- External API: Responsive
|
|
- Processing: Normal
|
|
- Status: Processing
|
|
|
|
### 4.2 Successful Completion
|
|
- **Time:** 16:56 UTC
|
|
- **Completion:**
|
|
1. Transaction: Processed successfully
|
|
2. Conversion: Completed
|
