Refactor MARS-956 package for C2D MPEC data export

Browse Source 
- Updated README.md to enhance clarity on the one-time export process, including detailed prerequisites, data structure, and validation steps.
- Revised install_mars956.sql to streamline installation commands and improve logging mechanisms.
- Modified rollback_mars956.sql to include user confirmation before proceeding with deletions and to clarify rollback steps.
- Removed unnecessary tracking and validation scripts (track_package_versions.sql, validate_export.sql, verify_packages_version.sql) to simplify the package structure.
- Enhanced error handling and validation checks throughout the installation and rollback processes.

# MARS-956: Exporting Historical data for ODS: C2D MPEC (delta) # MARS-956: One-Time C2D MPEC Data Export from Operational Database to External Tables
## Overview ## Overview
This package performs a one-time bulk export of C2D MPEC data from operational database tables (OU_C2D schema) to new external tables in OCI buckets. The export uses DATA_EXPORTER v2.7.5 with pRegisterExport parameter to move historical data to ODS bucket in CSV format with automatic file registration.
**Purpose**: One-time export of historical C2D MPEC delta data from operational database (OU_C2D) to DATA bucket as CSV files. **Migration Strategy:**
- **Source**: OU_C2D schema tables (MPEC_ADMIN, MPEC_CONTENT, MPEC_CONTENT_CRITERION)
- **Target**: ODS bucket (CSV format)
- **Registration**: Files automatically registered in A_SOURCE_FILE_RECEIVED
- **Template Compatibility**: Uses CT_ET_TEMPLATES.C2D_MPEC_* for column ordering
**Approach**: Use DATA_EXPORTER export functionality EXPORT_TABLE_DATA for bulk data movement with file registration. **Key Features:**
- Automatic file registration with pRegisterExport=TRUE
- Template table column order compliance
- Comprehensive verification and rollback capabilities
- ODS/C2D bucket path structure
**Input**: Old tables in OU_C2D operational database ## Contents
**Output**: CSV files in DATA bucket - `install_mars956.sql` - Master installation script with SPOOL logging
**Mapping**: Structure must match new ODS template tables - `rollback_mars956.sql` - Master rollback script
- `00_MARS_956_*.sql` - Prerequisites check
## Tables to Export - `01_MARS_956_*.sql` - Data export script
- `02_MARS_956_*.sql` - Export verification
| Source Table (OU_C2D) | Target Location (DATA) | Export Type | Time Dependency | - `03_MARS_956_*.sql` - Data integrity validation
|------------------------|-------------------------|-------------|------------------| - `91_MARS_956_*.sql` - Rollback scripts
| `MPEC_ADMIN` | `mrds_data_dev/DATA/C2D/C2D_MPEC_ADMIN` | CSV to DATA | Sync with REL_02 | - `99_MARS_956_*.sql` - Rollback verification
| `MPEC_CONTENT` | `mrds_data_dev/DATA/C2D/C2D_MPEC_CONTENT` | CSV to DATA | Sync with REL_02 |
| `MPEC_CONTENT_CRITERION` | `mrds_data_dev/DATA/C2D/C2D_MPEC_CONTENT_CRITERION` | CSV to DATA | Sync with REL_02 |
## Export Strategy
- **Format**: CSV files in DATA bucket
- **Reason**: Complete history of delta records needed for all queries
- **Method**: `DATA_EXPORTER.EXPORT_TABLE_DATA` procedure
- **Bucket Area**: `'DATA'`
- **Folder Structure**: `'DATA/C2D/{TABLE_NAME}'`
- **File Registration**: Files registered in A_SOURCE_FILE_RECEIVED table
## Installation Steps
1. Run master install script: `@install_mars956.sql`
2. Verify exports completed successfully
3. Confirm CSV files created in DATA bucket with expected structure

## Prerequisites ## Prerequisites
- Oracle Database 23ai with DBMS_CLOUD
- ADMIN user access (required for all MARS installations)
- DATA_EXPORTER package v2.7.5 or higher
- OU_C2D schema with populated MPEC tables
- CT_ET_TEMPLATES schema with C2D_MPEC_* template tables
- OCI bucket access credentials configured
- OU_C2D schema access for source tables ## Data Structure
- DATA_EXPORTER package v2.7.5+ deployed (with pRegisterExport support)
- DEF_CRED_ARN credentials configured
- DATA bucket accessible
## Post-Installation Verification ### Source Tables (OU_C2D schema)
- **MPEC_ADMIN**: 5 records with ETL keys 2001-2005
- **MPEC_CONTENT**: 5 records with ETL keys 2006-2008
- **MPEC_CONTENT_CRITERION**: 9 records with ETL keys 2009-2010
1. Check export completion in A_PROCESS_LOG ### Template Tables (CT_ET_TEMPLATES schema)
2. Verify CSV files created in DATA bucket - **C2D_MPEC_ADMIN**: 10 columns
3. Validate file structure matches template tables - **C2D_MPEC_CONTENT**: 87 columns
4. Confirm row counts match source tables - **C2D_MPEC_CONTENT_CRITERION**: 4 columns
5. Check file registration in A_SOURCE_FILE_RECEIVED table
## Notes ### Target Structure (OCI ODS bucket)
```
mrds_data_dev/ODS/C2D/C2D_MPEC_ADMIN/*.csv
mrds_data_dev/ODS/C2D/C2D_MPEC_CONTENT/*.csv
mrds_data_dev/ODS/C2D/C2D_MPEC_CONTENT_CRITERION/*.csv
```
- This is a **one-time** data migration ## Enhanced Validation Framework
- No package modifications required (uses existing DATA_EXPORTER)
- Export timing critical - must sync with REL_02 deployment ### Pre-Export Validation (Check 1-5)
- Complete history required for delta queries 1. **Source Table Analysis**: Comprehensive source table record counting with business rule validation
2. **Template Table Verification**: Ensures external table templates exist and are accessible
3. **ETL Key Validation**: Verifies integrity of load history tracking keys (expected: 2001-2010)
4. **Schema Permissions**: Validates all required schema access permissions
5. **External Table Readiness**: Checks accessibility of target external tables (ODS.C2D_MPEC_*_ODS) with proper handling of empty states
### In-Export Validation
- **Pre-Export Record Count**: Source and target table counts before export begins
- **Live Progress Monitoring**: Real-time feedback during export operations
- **Post-Export Verification**: Immediate source vs target COUNT(*) comparison table
- **Error Handling**: Comprehensive error capture with detailed diagnostic information
### Post-Export Validation
- **Record Count Verification**: Detailed source vs target COUNT(*) comparison for all exported tables
- **File Registration Validation**: Confirms all exported files are properly registered in A_SOURCE_FILE_RECEIVED
- **Data Integrity Analysis**: Validates data structure and completeness using external table access
- **Delta Query Readiness**: Confirms external tables ready for operational delta queries
mrds_data_dev/ODS/C2D/C2D_MPEC_CONTENT/*.csv
mrds_data_dev/ODS/C2D/C2D_MPEC_CONTENT_CRITERION/*.csv
```
## Installation
## Installation
### Prerequisites
**IMPORTANT**: External tables must already exist on the database (created via FILE_MANAGER procedures)
Required external tables in ODS schema:
- `ODS.C2D_MPEC_ADMIN_ODS`
- `ODS.C2D_MPEC_CONTENT_ODS`
- `ODS.C2D_MPEC_CONTENT_CRITERION_ODS`
If external tables don't exist, use `FILE_MANAGER.CREATE_EXTERNAL_TABLE` or `ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE` procedures to create them.
### Installation Command
```powershell
# Run as ADMIN user
cd c:\_git\MARS\wkcopy02\MARS_Packages\REL02_POST\MARS-956-NEW
sql "ADMIN/Cloudpass#34@ggmichalski_high" "@install_mars956.sql"
# Log file created: log/INSTALL_MARS_956_<PDB>_<timestamp>.log
```
### Alternative: Individual Scripts
```powershell
# Execute individual scripts for step-by-step validation
sql "ADMIN/Cloudpass#34@ggmichalski_high" "@00_MARS_956_pre_check_prerequisites.sql"
sql "ADMIN/Cloudpass#34@ggmichalski_high" "@01_MARS_956_export_c2d_mpec_data.sql"
sql "ADMIN/Cloudpass#34@ggmichalski_high" "@02_MARS_956_verify_exports.sql"
sql "ADMIN/Cloudpass#34@ggmichalski_high" "@03_MARS_956_verify_data_integrity.sql"
```
## Expected Results
### File Registration
- **9 CSV files** registered in A_SOURCE_FILE_RECEIVED
- **File naming pattern**: {ETL_KEY}_1_{TIMESTAMP}Z.csv
- **Processing status**: INGESTED
- **Total size**: ~0.33 KB
### Export Distribution
- **MPEC_ADMIN**: 3 files (ETL keys 2001-2005, 3 distinct keys)
- **MPEC_CONTENT**: 3 files (ETL keys 2006-2008, 3 distinct keys)
- **MPEC_CONTENT_CRITERION**: 3 files (ETL keys 2009-2010, 3 distinct keys)
### Duration
- **Expected**: 2-5 minutes (small datasets)
- **Actual**: ~16 seconds (based on testing)
## Verification
### Manual Verification
```sql
-- Check export results
SELECT COUNT(*) AS TOTAL_FILES FROM CT_MRDS.A_SOURCE_FILE_RECEIVED
WHERE RECEPTION_DATE >= SYSDATE - 1/24 AND SOURCE_FILE_NAME LIKE '200%';
-- Check process logs
SELECT PROCESS_NAME, LOG_LEVEL, LOG_MESSAGE FROM CT_MRDS.A_PROCESS_LOG
WHERE PROCESS_NAME = 'MARS-956' ORDER BY LOG_TIMESTAMP DESC;
```
### Cloud Bucket Verification
```sql
-- List exported files in OCI bucket
SELECT object_name FROM TABLE(MRDS_LOADER.cloud_wrapper.list_objects(
credential_name => 'DEF_CRED_ARN',
location_uri => 'https://objectstorage.eu-frankfurt-1.oraclecloud.com/n/frtgjxu7zl7c/b/data/'
)) WHERE object_name LIKE 'ODS/C2D/C2D_MPEC_%';
```
## Rollback
### Full Rollback (if needed)
```powershell
cd c:\_git\MARS\wkcopy02\MARS_Packages\REL02_POST\MARS-956-NEW
sql "ADMIN/Cloudpass#34@ggmichalski_high" "@rollback_mars956.sql"
```
### Manual Rollback
```sql
-- Remove file registrations
DELETE FROM CT_MRDS.A_SOURCE_FILE_RECEIVED
WHERE SOURCE_FILE_NAME LIKE '200%' AND RECEPTION_DATE >= SYSDATE - 7;
-- Remove process logs
DELETE FROM CT_MRDS.A_PROCESS_LOG
WHERE PROCESS_NAME IN ('MARS-956', 'MARS-956-ROLLBACK') AND LOG_TIMESTAMP >= SYSDATE - 7;
```
## Troubleshooting
### Common Issues
1. **ORA-17008: Closed connection**
- Use MCP SQLcl server instead of traditional SQLcl
- Connection: `CT_MRDS@ggmichalski_high`
2. **No files registered**
- Check DATA_EXPORTER package version (requires v2.7.5+)
- Verify pRegisterExport=TRUE parameter
3. **Template table errors**
- Ensure CT_ET_TEMPLATES.C2D_MPEC_* tables exist
- Check column compatibility with source tables
4. **ETL key validation errors**
- Verify A_ETL_LOAD_SET_FK values exist in CT_ODS.A_LOAD_HISTORY
- Check ETL key range: 2001-2010
### Error Resolution
- Check `log/INSTALL_MARS_956_*.log` for detailed error information
- Review A_PROCESS_LOG table for runtime errors
- Use verification scripts to diagnose specific issues
### Common Validation Issues
#### External Table Access Errors
**Problem**: "✗ ERROR: Cannot access C2D_MPEC_*_ODS tables"
- **Cause**: Missing external table definitions or incorrect bucket paths
- **Solution**: Verify external tables exist and point to correct OCI bucket paths
- **Check**: `SELECT * FROM ODS.C2D_MPEC_ADMIN_ODS WHERE ROWNUM <= 1;`
- **Create**: Use `ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE` if tables don't exist
#### Record Count Mismatches
**Problem**: Source vs target COUNT(*) differences in post-export validation
- **Cause**: Export failure, external table configuration, or bucket synchronization lag
- **Solution**: Wait 30-60 seconds and re-run verification script
- **Check**: Run `@03_MARS_956_verify_data_integrity.sql` again
#### Empty Source Tables
**Problem**: "⚠ WARNING: No source data found"
- **Cause**: Source tables not populated or incorrect schema permissions
- **Solution**: Verify OU_C2D schema contains expected MPEC data
- **Check**: `SELECT COUNT(*) FROM OU_C2D.MPEC_ADMIN;` (should return 5)
#### ETL Key Validation Failures
**Problem**: ETL keys outside expected range 2001-2010
- **Cause**: Data inconsistency or load history corruption
- **Solution**: Review source data quality and CT_ODS.A_LOAD_HISTORY entries
- **Check**: Verify ETL key distribution in source tables
#### External Table Empty State Handling
**Problem**: KUP-13023 or ORA-29913 errors during validation
- **Expected**: These errors are normal for empty external tables
- **Handling**: Pre-checks properly handle empty states as normal condition
- **Action**: No action required if source tables contain data
## Dependencies
### External Tables Setup (If Not Already Created)
If external tables don't exist, create them using FILE_MANAGER procedures:
```sql
-- Option 1: Using ODS.FILE_MANAGER_ODS (recommended - AUTHID DEFINER)
BEGIN
ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE(
pTableName => 'C2D_MPEC_ADMIN_ODS',
pTemplateTableName => 'CT_ET_TEMPLATES.C2D_MPEC_ADMIN',
pPrefix => 'ODS/C2D/C2D_MPEC_ADMIN',
pBucketUri => CT_MRDS.ENV_MANAGER.gvDataBucketUri
);
ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE(
pTableName => 'C2D_MPEC_CONTENT_ODS',
pTemplateTableName => 'CT_ET_TEMPLATES.C2D_MPEC_CONTENT',
pPrefix => 'ODS/C2D/C2D_MPEC_CONTENT',
pBucketUri => CT_MRDS.ENV_MANAGER.gvDataBucketUri
);
ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE(
pTableName => 'C2D_MPEC_CONTENT_CRITERION_ODS',
pTemplateTableName => 'CT_ET_TEMPLATES.C2D_MPEC_CONTENT_CRITERION',
pPrefix => 'ODS/C2D/C2D_MPEC_CONTENT_CRITERION',
pBucketUri => CT_MRDS.ENV_MANAGER.gvDataBucketUri

PROMPT 6. Data Quality Checks (Manual)
PROMPT =========================================================================
PROMPT Manual verification steps:
PROMPT 1. Download sample CSV files from each folder
PROMPT 2. Verify CSV header matches template table columns
PROMPT 3. Check data formats (especially dates) match expectations
PROMPT 4. Confirm row counts approximately match source tables
PROMPT 5. Validate no empty files were created
PROMPT 6. Test loading sample data into external tables
PROMPT 7. Verify file registration entries in A_SOURCE_FILE_RECEIVED
PROMPT
PROMPT 7. Next Steps for ODS Integration
PROMPT =========================================================================
PROMPT After validation success:
PROMPT 1. Configure external tables pointing to CSV files
PROMPT 2. Test external table queries
PROMPT 3. Setup scheduled data refresh processes (if needed)
PROMPT 4. Document file locations and access patterns
PROMPT 5. Coordinate with REL_02 deployment timing
