CCF Extractor

Troubleshooting Common Issues in CCF Extractor

1. Extraction fails or produces no output

• Check input file integrity: Ensure the CCF file isn’t corrupted—open it with a hex editor or a known viewer.
• Verify file format/version: Confirm the extractor supports the CCF version. If not, convert or update the extractor.
• Insufficient permissions: Run the extractor with read access to the file and write access to the output directory.
• Memory limits: For very large files, increase available memory or use streaming mode if supported.

2. Partial or truncated output

• Interrupted processing: Look for process termination or timeout logs; increase timeout limits.
• Malformed archive sections: Identify damaged blocks and try repairing or extracting unaffected sections.
• Resource exhaustion: Monitor CPU/RAM/disk I/O; free resources or run on a machine with higher capacity.

3. Incorrectly parsed fields or data corruption in output

• Schema mismatch: Ensure the extractor’s parsing schema matches the CCF structure (field names, types, encoding).
• Encoding issues: Confirm character encodings (UTF-8 vs. UTF-16) and apply correct decoding.
• Endianess/byte-order errors: If binary fields look wrong, try swapping endianness in parsing settings.

4. Performance is too slow

• I/O bottleneck: Use faster disks (SSD), increase read buffer sizes, or process files locally instead of over network mounts.
• Single-threaded processing: Enable parallel extraction or shard the file if the extractor supports it.
• Unnecessary logging: Reduce log verbosity or disable synchronous logging during large jobs.

5. Dependency or environment errors

• Missing libraries: Confirm required runtime libraries and versions are installed (check docs or dependency manifest).
• Version conflicts: Use a virtual environment or container to isolate dependencies.
• Permissions for native modules: If native extensions are used, ensure they’re built for your OS/architecture.

6. Authentication or access errors (for remote CCF sources)

• Invalid credentials: Verify tokens/keys and refresh if expired.
• Network/firewall issues: Test connectivity to the source endpoint and open required ports.
• Rate limits: Check API rate limits and add retry/backoff logic.

7. Unexpected crashes or exceptions

• Collect logs and stack traces: Identify the failing module and line.
• Reproduce with minimal input: Isolate a small test file that triggers the crash.
• Update/patch: Apply vendor updates; check issue tracker for known bugs and workarounds.

8. Validation failures after extraction

• Schema validation: Run output against the expected schema and list failing fields.
• Data type coercion: Ensure numeric/date fields are parsed into correct types and normalized.
• Duplicates/missing records: Check source indices and extraction filters that might drop records.

Quick diagnostic checklist (ordered)

1. Confirm file validity and supported CCF version.
2. Check permissions and available resources.
3. Inspect logs for errors/stack traces.
4. Verify parsing schema and encodings.
5. Test on a smaller sample file.
6. Update extractor and dependencies.
7. Re-run with increased time/memory or in an isolated environment.
