This article provides suggestions to troubleshoot common problems with the Oracle connector in Azure Data Factory and Azure Synapse.

Error code: ArgumentOutOfRangeException

  • Message: Hour, Minute, and Second parameters describe an un-representable DateTime.

  • Cause: In Azure Data Factory and Synapse pipelines, DateTime values are supported in the range from 0001-01-01 00:00:00 to 9999-12-31 23:59:59. However, Oracle supports a wider range of DateTime values, such as the BC century or min/sec>59, which leads to failure.

  • Recommendation:

    To see whether the value in Oracle is in the supported range of dates, run select dump(<column name>).

    To learn the byte sequence in the result, see How are dates stored in Oracle?.

Add secure algorithms when using the self-hosted integration runtime version 5.36.8726.3 or higher

  • Symptoms: When you use the self-hosted integration runtime version 5.36.8726.3 or higher, you meet this error message: [Oracle]ORA-12650: No common encryption or data integrity algorithm.

  • Cause: The secure algorithm is not added to your Oracle server.

  • Recommendation: Update your Oracle server settings to add these secure algorithms:

    • The following algorithms are deemed as secure by OpenSSL, and will be sent along to the server for OAS (Oracle Advanced Security) encryption.

      • AES256
      • AES192
      • 3DES168
      • AES128
      • 3DES112
      • DES

    • The following algorithms are deemed as secure by OpenSSL, and will be sent along to the server for OAS (Oracle Advanced Security) data integrity.

      • SHA256
      • SHA384
      • SHA512
