Update DATA_EXPORTER package to version 2.8.0, refactor EXPORT_TABLE_DATA to export to a single CSV file, and add pFileName and pMaxFileSize parameters.

- 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
+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  
-**Output**: CSV files in DATA bucket  
-**Mapping**: Structure must match new ODS template tables
-
-## Tables to Export
-
-| Source Table (OU_C2D) | Target Location (DATA) | Export Type | Time Dependency |
-|------------------------|-------------------------|-------------|------------------|
-| `MPEC_ADMIN` | `mrds_data_dev/DATA/C2D/C2D_MPEC_ADMIN` | CSV to DATA | Sync with REL_02 |
-| `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

-## 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
-- No package modifications required (uses existing DATA_EXPORTER)
-- Export timing critical - must sync with REL_02 deployment
-- Complete history required for delta queries
+## Enhanced Validation Framework
+
+### Pre-Export Validation (Check 1-5)
+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

+
+## 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',

+        pBucketUri => CT_MRDS.ENV_MANAGER.gvDataBucketUri
+    );
+END;
+/
+
+-- Option 2: Using CT_MRDS.FILE_MANAGER (AUTHID CURRENT_USER - requires ODS context)
+-- Connect as ODS user first
+-- Then call CT_MRDS.FILE_MANAGER.CREATE_EXTERNAL_TABLE with same parameters
+```
+
+### Package Dependencies
+- **CT_MRDS.DATA_EXPORTER** v2.7.5+ (with pRegisterExport support)
+- **CT_MRDS.ENV_MANAGER** v3.1.0+
