-           or references to other, non-existent procedures.  For views,
-           the problem could be a reference in the view's defining query to
-           a non-existent table.
-           Can also be a table which has references to non-existent or
-           inaccessible types.
-*Action:   Fix the errors and/or create referenced objects as necessary.

Prevents concurrent sessions from deleting each other chunks. Session-safe cleanup with TASK_NAME filtering. Enables true parallel execution of multiple export jobs.' || CHR(10) ||

Eliminates single dateformat limitation of DBMS_CLOUD.EXPORT_DATA.' || CHR(10) ||

Each year/month partition processed in separate thread for improved performance.' || CHR(10) ||

-# MARS-835: One-Time CSDB Data Export from Operational Database to External Tables
-
-## Overview
-This package performs a one-time bulk export of CSDB data from operational database tables (OU_CSDB schema) to new external tables in OCI buckets. The export uses DATA_EXPORTER v2.4.0 with per-column date format handling to move historical data to either DATA bucket (CSV format) or HIST bucket (Parquet format with Hive-style partitioning).
-
-**Migration Strategy:**
-- **Split Export (2 tables)**: DEBT, DEBT_DAILY - Last 6 months → DATA (CSV), Older data → HIST (Parquet)
-- **HIST Only (4 tables)**: INSTR_RAT_FULL, INSTR_DESC_FULL, ISSUER_RAT_FULL, ISSUER_DESC_FULL - All data → HIST (Parquet)
-
-**Key Transformations:**
-- Column rename: `A_ETL_LOAD_SET_FK` → `A_WORKFLOW_HISTORY_KEY` (all tables)
-- Column removal: DEBT (2 columns), DEBT_DAILY (6 columns) not required in new structure
-
-## Contents
-- `install_mars835.sql` - Master installation script with SPOOL logging
-- `rollback_mars835.sql` - Master rollback script
-- `01_MARS_835_*.sql` - Individual installation scripts
-- `91_MARS_835_*.sql` - Individual rollback scripts
-- `track_package_versions.sql` - Package version tracking
-- `verify_packages_version.sql` - Package verification
-
-## Prerequisites
-- Oracle Database 23ai
-- ADMIN user access (required for all MARS installations)
-- ENV_MANAGER v3.1.0+
-- Required schema privileges
-
-## Installation
-
-### Option 1: Master Script (Recommended)
-```powershell
-# IMPORTANT: Execute as ADMIN user for proper privilege management
-Get-Content "MARS_Packages/REL01_POST_DEACTIVATION/MARS-835/install_mars835.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-
-# Log file created: log/INSTALL_MARS_835_<PDB>_<timestamp>.log
-```
-
-### Option 2: Individual Scripts
-```powershell
-# IMPORTANT: Execute as ADMIN user
-Get-Content "01_MARS_835_*.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-Get-Content "02_MARS_835_*.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-# ... etc
-```
-
-## Verification
-```sql
--- Verify package versions
-SELECT PACKAGE_NAME.GET_VERSION() FROM DUAL;
-
--- Check for errors (ADMIN user checks specific schema)
-SELECT * FROM ALL_ERRORS 
-WHERE OWNER = 'CT_MRDS'  -- Replace with target schema
-  AND NAME = 'PACKAGE_NAME';
-
--- Verify no untracked changes
-SELECT ENV_MANAGER.CHECK_PACKAGE_CHANGES('CT_MRDS', 'PACKAGE_NAME') FROM DUAL;
-```
-
-## Rollback
-```powershell
-# IMPORTANT: Execute as ADMIN user
-Get-Content "MARS_Packages/REL01_POST_DEACTIVATION/MARS-835/rollback_mars835.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-
-**NOTE**: Rollback for data exports is **NOT RECOMMENDED** as it would delete exported files from OCI buckets. Only use rollback if export failed and needs to be restarted.
-```
-
-## Expected Changes
-
-### Data Export Summary
-**6 CSDB tables exported from OU_CSDB schema:**
-
-**Group 1: Split DATA + HIST (Time Critical)**
-1. **DEBT** - Last 6 months → DATA, Older → HIST
-2. **DEBT_DAILY** - Last 6 months → DATA, Older → HIST
-
-**Group 2: HIST Only (Weekend Bulk)**
-3. **INSTR_RAT_FULL** - All data → HIST
-4. **INSTR_DESC_FULL** - All data → HIST
-5. **ISSUER_RAT_FULL** - All data → HIST
-6. **ISSUER_DESC_FULL** - All data → HIST
-
-### Bucket Destinations (DEV environment)
-- **DATA Bucket**: `mrds_data_dev/ODS/CSDB/` (CSV format)
-- **HIST Bucket**: `mrds_hist_dev/ARCHIVE/CSDB/` (Parquet with partitioning)
-
-### Column Mappings
-- **All tables**: `A_ETL_LOAD_SET_FK` renamed to `A_WORKFLOW_HISTORY_KEY`
-- **DEBT**: Removed columns: `IDIRDEPOSITORY`, `VA_BONDDURATION`
-- **DEBT_DAILY**: Removed columns: `STEPID`, `PROGRAMNAME`, `PROGRAMCEILING`, `PROGRAMSTATUS`, `ISSUERNACE21SECTOR`, `INSTRUMENTQUOTATIONBASIS`
-
-## Testing
-
-### Post-Export Verification
-
-1. **Verify CSV files in DATA bucket** (DEBT, DEBT_DAILY - last 6 months):
-```sql
--- Check exported files
-SELECT object_name, bytes 
-FROM TABLE(DBMS_CLOUD.LIST_OBJECTS(
-    credential_name => 'DEF_CRED_ARN',
-    location_uri => 'https://objectstorage.region.oraclecloud.com/n/namespace/b/mrds_data_dev/o/ODS/CSDB/'
-)) WHERE object_name LIKE '%CSDB_DEBT%';
-```
-
-2. **Verify Parquet files in HIST bucket** (all 6 tables):
-```sql
--- Check archived files with Hive partitioning
-SELECT object_name, bytes 
-FROM TABLE(DBMS_CLOUD.LIST_OBJECTS(
-    credential_name => 'DEF_CRED_ARN',
-    location_uri => 'https://objectstorage.region.oraclecloud.com/n/namespace/b/mrds_hist_dev/o/ARCHIVE/CSDB/'
-)) WHERE object_name LIKE '%PARTITION_YEAR=%';
-```
-
-3. **Validate row counts match source tables**:
-```sql
--- Compare counts between source and exported data
-SELECT COUNT(*) FROM OU_CSDB.DEBT;
-SELECT COUNT(*) FROM ODS.CSDB_DEBT_ODS;  -- External table pointing to DATA
-SELECT COUNT(*) FROM ODS.CSDB_DEBT_ARCHIVE;  -- External table pointing to HIST
-```
-
-4. **Verify column mappings**:
-```sql
--- Check A_WORKFLOW_HISTORY_KEY exists in exported data
-SELECT A_WORKFLOW_HISTORY_KEY, COUNT(*) 
-FROM ODS.CSDB_DEBT_ARCHIVE 
-GROUP BY A_WORKFLOW_HISTORY_KEY;
-```
-
-## Known Issues
-
-### Timing Constraints
-- **DATA exports (DEBT, DEBT_DAILY)**: Must execute during parallel old+new loads phase after Production deployment
-- **HIST exports (all 6 tables)**: Can run anytime, recommended for weekend bulk execution to avoid interference
-
-### Environment-Specific Configuration
-- Bucket names must be adjusted for each environment:
-  - DEV: `mrds_data_dev`, `mrds_hist_dev`
-  - TEST: `mrds_data_test`, `mrds_hist_test`  
-  - PROD: `mrds_data_prod`, `mrds_hist_prod`
-
-### Data Cutoff Date
-- Export scripts use 6-month cutoff date calculated as `ADD_MONTHS(SYSDATE, -6)`
-- Verify cutoff aligns with business requirements before execution
-
-### One-Time Execution
-- This is a **ONE-TIME data migration** package
-- After successful execution, package should be **deactivated** (moved to REL01_POST_DEACTIVATION)
-- Do not re-run unless explicitly required for data refresh

-# MARS-835: Required External Tables for Smart Column Mapping
-
-## Overview
-This document lists all external tables required for MARS-835 data exports using DATA_EXPORTER v2.4.0 with Smart Column Mapping feature.
-
-**Purpose**: Smart Column Mapping ensures CSV files are generated with columns in the EXACT order expected by external tables, preventing NULL values due to Oracle's positional CSV mapping.
-
----
-
-## Required External Tables
-
-### Group 1: DATA Bucket (CSV Format) - **CRITICAL**
-
-#### 1. ODS.CSDB_DEBT_DATA_ODS
-- **Source Table**: OU_CSDB.LEGACY_DEBT
-- **Format**: CSV
-- **Bucket**: DATA (mrds_data_dev/ODS/CSDB/CSDB_DEBT/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY (position 2 recommended)
-- **Critical**: Must use Smart Column Mapping to avoid NULL values in A_WORKFLOW_HISTORY_KEY
-
-#### 2. ODS.CSDB_DEBT_DAILY_DATA_ODS
-- **Source Table**: OU_CSDB.LEGACY_DEBT_DAILY
-- **Format**: CSV

-## External Table Column Order Requirements
-
-### **CRITICAL for CSV Tables** (DATA bucket):
-
-All CSV external tables MUST have **A_WORKFLOW_HISTORY_KEY at position 2**:
-
-```
-Position 1: A_KEY (NUMBER)
-Position 2: A_WORKFLOW_HISTORY_KEY (NUMBER)  ← MUST BE HERE!
-Position 3+: Other columns in any order
-```
-
-**Reason**: Oracle External Tables with CSV format use **positional mapping** (ignore header row). If source table has A_ETL_LOAD_SET_FK at position 72, but CSV puts it at position 72 while external table expects A_WORKFLOW_HISTORY_KEY at position 2, the external table will try to read position 2 (which might be a DATE column) as NUMBER → conversion fails → NULL value.
-
-**Solution**: Smart Column Mapping (v2.4.0) generates CSV columns in EXTERNAL TABLE order, ensuring position 2 has the correct NUMBER value.
-
-### **OPTIONAL for Parquet Tables** (ARCHIVE bucket):
-
-Parquet format uses **schema-based mapping** (column names). Column order doesn't matter, but Smart Column Mapping provides consistency.
-
----
-
-## Creation Script Example
-
-### CSV External Table (CRITICAL - Correct Column Order)
-
-```sql
--- Example: ODS.CSDB_DEBT_DATA_ODS
--- IMPORTANT: A_WORKFLOW_HISTORY_KEY must be at position 2!
-
-BEGIN
-    ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE(
-        pTableName => 'CSDB_DEBT_DATA_ODS',
-        pTemplateTableName => 'CT_ET_TEMPLATES.CSDB_DEBT_TEMPLATE',
-        pPrefix => 'ODS/CSDB/CSDB_DEBT',
-        pBucketUri => CT_MRDS.ENV_MANAGER.gvDataBucketUri,
-        pFormat => 'CSV'  -- Uses positional mapping!
-    );
-END;
-/
-
--- Verify column order (A_WORKFLOW_HISTORY_KEY should be position 2)
-SELECT column_id, column_name, data_type
-FROM all_tab_columns
-WHERE table_name = 'CSDB_DEBT_DATA_ODS'
-  AND owner = 'ODS'
-ORDER BY column_id;
-```
-
-### Parquet External Table (Optional Column Order)
-
-```sql
--- Example: ODS.CSDB_DEBT_ARCHIVE
--- Column order flexible (schema-based mapping)
-
-BEGIN
-    ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE(
-        pTableName => 'CSDB_DEBT_ARCHIVE',
-        pTemplateTableName => 'CT_ET_TEMPLATES.CSDB_DEBT_TEMPLATE',
-        pPrefix => 'ARCHIVE/CSDB/CSDB_DEBT',
-        pBucketUri => CT_MRDS.ENV_MANAGER.gvArchiveBucketUri,
-        pFormat => 'PARQUET'  -- Uses schema-based mapping
-    );
-END;
-/
-```
-
----
-
-## Template Tables Required
-
-All external tables require corresponding template tables in CT_ET_TEMPLATES schema:
-
-- `CT_ET_TEMPLATES.CSDB_DEBT_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_DEBT_DAILY_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_INSTR_RAT_FULL_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_INSTR_DESC_FULL_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_ISSUER_RAT_FULL_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_ISSUER_DESC_FULL_TEMPLATE`
-
-**Note**: Template tables must be created by ADMIN or CT_ET_TEMPLATES user (MRDS_LOADER cannot create them).
-
----
-
-## Verification Checklist
-
-Before running MARS-835 exports:
-
-- [ ] All 8 external tables exist in ODS schema
-- [ ] CSV tables (DATA bucket) have A_WORKFLOW_HISTORY_KEY at position 2
-- [ ] Template tables exist in CT_ET_TEMPLATES schema
-- [ ] MRDS_LOADER has EXECUTE privilege on ODS.FILE_MANAGER_ODS
-- [ ] ODS schema has access to CT_MRDS.ENV_MANAGER for logging
-- [ ] DATA_EXPORTER v2.4.0 deployed with Smart Column Mapping feature
-
----
-
-## Testing Verification
-
-After export, verify A_WORKFLOW_HISTORY_KEY is not NULL:
-
-```sql
--- CSV tables (should be 100% populated)
-SELECT 'CSDB_DEBT_DATA_ODS' AS TABLE_NAME,
-       COUNT(*) AS TOTAL_ROWS,
-       COUNT(A_WORKFLOW_HISTORY_KEY) AS NON_NULL_COUNT,
-       ROUND(COUNT(A_WORKFLOW_HISTORY_KEY) * 100.0 / NULLIF(COUNT(*), 0), 2) AS SUCCESS_RATE_PCT
-FROM ODS.CSDB_DEBT_DATA_ODS;
-
-SELECT 'CSDB_DEBT_DAILY_DATA_ODS' AS TABLE_NAME,
-       COUNT(*) AS TOTAL_ROWS,
-       COUNT(A_WORKFLOW_HISTORY_KEY) AS NON_NULL_COUNT,
-       ROUND(COUNT(A_WORKFLOW_HISTORY_KEY) * 100.0 / NULLIF(COUNT(*), 0), 2) AS SUCCESS_RATE_PCT
-FROM ODS.CSDB_DEBT_DAILY_DATA_ODS;
-
--- Parquet tables (should also be 100% populated)
-SELECT 'CSDB_DEBT_ARCHIVE' AS TABLE_NAME,
-       COUNT(*) AS TOTAL_ROWS,
-       COUNT(A_WORKFLOW_HISTORY_KEY) AS NON_NULL_COUNT,
-       ROUND(COUNT(A_WORKFLOW_HISTORY_KEY) * 100.0 / NULLIF(COUNT(*), 0), 2) AS SUCCESS_RATE_PCT
-FROM ODS.CSDB_DEBT_ARCHIVE;
-```
-
-**Expected Result**: SUCCESS_RATE_PCT = 100.00 for all tables
