Understanding Oracle Data Integrator Repository Architecture
Before diving into backup procedures, it’s important to understand that Oracle Data Integrator’s repository consists of two main components:
- Master Repository
- Work Repository
The Master Repository stores ODI security information, topology details, and version management data, while the Work Repository contains actual project implementations and execution information.
Key Components of ODI Repository Backup
When working with Oracle Business Intelligence Applications, the ODI repository backup process becomes more critical due to the tight integration between different components. Here are the essential elements:
– Master Repository backup procedures
– Work Repository synchronization
– OBIA-specific considerations
– Version management
– Security settings preservation
Oracle Data Integrator Backup Methods
Method 1: Database Export Approach
Sql
expdp system/password@database
DIRECTORY=backup_dir
DUMPFILE=odi_master_%DATE%.dmp
SCHEMAS=DEV_ODI_REPO
LOGFILE=odi_master_export_%DATE%.log
This method is particularly useful when working with Oracle Warehouse Builder migrations or when integrating with Oracle Business Intelligence systems.
Method 2: ODI Built-in Backup Features
The Oracle ODI 12C provides built-in functionality for repository backup through:
- ODI Studio interface
- Command-line utilities
- Scripted automation options
Environment-Specific Considerations
Development Environment Backup Strategy
For development environments, consider these specific approaches:
- More frequent code repository backups
- Integration with version control systems
- Developer-specific workspace preservation
- Test case retention
Sql
-- Development environment backup script
CREATE OR REPLACE PROCEDURE backup_dev_repository AS
BEGIN
-- Backup development-specific objects
FOR dev_workspace IN (SELECT * FROM dev_workspaces) LOOP
-- Custom backup logic
backup_workspace(dev_workspace.id);
END LOOP;
COMMIT;
END;
/

)
PARTITION BY RANGE (backup_date)
(
PARTITION backup_q1_2024 VALUES LESS THAN (TO_DATE('2024-04-01', 'YYYY-MM-DD')),
PARTITION backup_q2_2024 VALUES LESS THAN (TO_DATE('2024-07-01', 'YYYY-MM-DD')),
PARTITION backup_q3_2024 VALUES LESS THAN (TO_DATE('2024-10-01', 'YYYY-MM-DD')),
PARTITION backup_q4_2024 VALUES LESS THAN (TO_DATE('2025-01-01', 'YYYY-MM-DD'))
);
Automated Health Checks
Implement regular health checks:
Sql
-- Repository health check procedure
CREATE OR REPLACE PROCEDURE check_repository_health AS
BEGIN
-- Check for orphaned objects
DELETE FROM sns_objects
WHERE parent_id NOT IN (SELECT object_id FROM sns_objects);
-- Verify repository consistency
UPDATE sns_objects
SET last_check_date = SYSDATE
WHERE status = 'VALID';
COMMIT;
END;
/

INSERT /*+ PARALLEL(auto) */ INTO backup_work_objects
SELECT /*+ PARALLEL(auto) */ * FROM sns_objects
WHERE object_type = 'WORK';
COMMIT;
END;
/
Backup Size Optimization
Implement these compression techniques:
Sql
-- Create compressed backup tables
CREATE TABLE compressed_backup_store (
backup_id NUMBER,
backup_date DATE,
backup_content BLOB
) COMPRESS FOR OLTP
TABLESPACE backup_ts
STORAGE (COMPRESS HIGH);
-- Procedure to manage backup compression
CREATE OR REPLACE PROCEDURE compress_backup_content AS
BEGIN
