    Hello Team,

    There is new requirement to mask the Teradata, kindly let me know can we mask the Teradata using delphix?
    I could not see the inbuilt connector to mask the Teradata.
    Kindly let me know how to connect to Teradata using Delphix masking tool

    Hi Pankaj,
    Good to hear from you.
    The answer to your question is further expanded on here (https://support.delphix.com/Delphix_Masking_Engine/Delphix_Extensibility_Support_(KBA5571)#Extensible_Masking_Connectors), but the short answer is that the underlying framework and API used to support JDBC connectors is supported. There is an Oracle Teradata JDBC driver that you can find more information about here: https://docs.oracle.com/cd/E21454_01/html/821-2596/agqky.html.

    What is not supported are source-specific issues that arise while attempting to mask data using a connector (like the one above, available from Oracle).

    I should add that any Type 4 compliant JDBC driver can be used, and Delphix supports the internal logistics. Delphix does not support issues with the drivers.

    Hope that helps,
    Michael

    Delphix support Teradata masking via JDBC driver. You can configure teradata driver via Delphix Extended connector.(ensure to use correct driver class name and driver need to be uploaded as a zip file and not jar file) Please note only on the fly masking works for teradata and hence you will need source and target db for teradata masking.
    With in place masking, you will observe that job is getting stucked while issuing commit due to inherent table locking mechanism of teradata

    Hello Bhupinder, 

    Could you please send me Teradata JDBC driver version and download link.

    I am using "terajdbc-20.00.00.11.jar" version, while performing masking facing error.

    Hi Pankaj,

    Teradata JDBC driver can be downloaded from :

    https://downloads.teradata.com/download/connectivity/jdbc-driver

    We have performed Teradata masking successfully using 16 version (Don't remember the fully qualified version name).

    Also, can you let me know what error you are getting ?

    Regards,

    Bhupinder Kwatra

    Hello Bhupinder, 

    While performing masking i am facing "[Teradata JDBC Driver] [TeraJDBC 20.00.00.11] [Error 1536] [SQLState HY000] Invalid connection parameter name URL" (As per Support team)

    I have successfully created the connector, able to connect to databases and able to see the tables present from the configured database.

    Successfully created and executed Profiling job, its worked fine.

    While executing on the fly masking job, the masking job fails.

    I have also checked with delphix support team, as per support team it is issue of Teradata JDBC driver.

    Could you please help me to provide the same JDBC driver that you have used in Terdata?

    Hi Pankaj,

    As i mentioned earlier, we have masked data successfully on Teradata using JDBC 16 version. Download the driver from https://repo1.maven.org/maven2/com/teradata/jdbc/terajdbc/16.20.00.13/ and give a try.

    It seems that current error that you are getting with 20 version is caused by driver incompatibility.

    Also, while masking Teradata with Delphix; keep an eye on the cost.

    Regards,

    Bhupinder Kwatra

    Hello Bhupinder, 

    Thanks for providing URL for the JDBC driver..!
    I have downloaded and imported it to delphix masking engine.

    I have tried to execute the same ON THE FLY masking job that we had, After masking a few records in the table i could see the masking job failed for the below reasons.

    Kindly find the below logs and let me know if we have any solution to that

    Hi Pankaj,

    Pls confirm if the job errored out before the commit ?

    Additionally, it seems that below error are caused by constraint violation ( [Error 1338] [SQLState HY000])

    I will suggest create a small table and first test the compatibility of the driver.

    Regards,
    Bhupinder Kwatra

    Hello Bhupinder, 

    I have tested masking job with small table and I could see that when there is NULL value preset in table for the column data type INTEGER, DATE then below error message after executing masking job 

    2023/08/24 10:48:09 - DelphixTableInsert.0 - 
    2023/08/24 10:48:09 - DelphixTableInsert.0 - Error inserting/updating row

     --> Column number 15 have NULL value
    The masking job works fine by unchecking the batch update check box, but the masking speed will be very slow 6K/MIN which will take days to mask teradata.
    Also, I have tried to update the NULL column with dummy values and ran a masking job with the batch update, it worked fine.
    in practice we will have more than 100 tables and we could not find a NULL value in the individual table, could you provide any workaround for this problem?
