The SYS.TRANSPORTABLE_EXPORT_PATHS view in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 is a critical data dictionary object that provides metadata about transportable export paths used during database operations, particularly for transportable tablespaces (TTS) and data pump exports. This view is owned by the SYS schema and is primarily leveraged by DBAs and system administrators to manage and monitor export operations that involve moving data across Oracle databases while maintaining structural integrity.

Purpose and Functionality

The SYS.TRANSPORTABLE_EXPORT_PATHS view serves as a reference for identifying valid export paths configured for transportable operations. It contains metadata about directories, file paths, and associated database objects that are permitted for use in transportable exports. This view is essential for ensuring compliance with Oracle's transportable tablespace (TTS) requirements, which enable efficient data movement between databases without requiring full database exports.

Key Columns and Metadata

The view typically includes the following columns:

• PATH_ID: A unique identifier for the export path.
• DIRECTORY_NAME: The Oracle directory object associated with the export location.
• FILE_PATH: The physical file system path where export files are stored.
• STATUS: Indicates whether the path is active or inactive.
• CREATED_BY: The user who created the export path entry.
• CREATION_DATE: The timestamp when the path was defined.

Usage in Oracle EBS

In Oracle EBS environments, transportable tablespaces are often used for:

• Data Migration: Moving large volumes of data between EBS instances (e.g., from development to production).
• Patching and Upgrades: Transporting metadata and data during EBS upgrades.
• Disaster Recovery: Replicating critical tablespaces to standby databases.

The SYS.TRANSPORTABLE_EXPORT_PATHS view helps administrators verify configured paths before initiating transportable operations, ensuring compliance with Oracle's TTS prerequisites.

Integration with Data Pump

Oracle Data Pump (expdp/impdp) relies on this view to validate export directories during transportable operations. For example:

expdp system/password TRANSPORT_TABLESPACES=APPS_TS 
  TRANSPORT_FULL_CHECK=Y DIRECTORY=DATA_PUMP_DIR 
  DUMPFILE=tts_export.dmp LOGFILE=tts_export.log

The DIRECTORY parameter must reference a valid path listed in SYS.TRANSPORTABLE_EXPORT_PATHS.

Security Considerations

Access to this view is typically restricted to users with SELECT_CATALOG_ROLE or DBA privileges due to its sensitive nature. In EBS, the APPS schema may require read access for certain automated patching utilities.

Best Practices

1. Regularly audit export paths to ensure they point to valid storage locations.
2. Document all transportable export paths used in EBS environments.
3. Monitor for unauthorized modifications to prevent data exfiltration risks.

Conclusion

The SYS.TRANSPORTABLE_EXPORT_PATHS view is a foundational component for transportable operations in Oracle EBS 12.1.1 and 12.2.2. By providing visibility into configured export paths, it enables DBAs to execute efficient data transfers while maintaining system integrity. Proper management of this view is essential for successful TTS implementations in enterprise EBS environments.
