JDBC Connector Troubleshooting Data Truncation

moss_snake_01 · January 22, 2024, 8:49pm

Hello! I am trying to troubleshoot a JDBC connector that is invoking a single SPROC for both CREATE and MODIFY operations (only two we’re focused on at the moment).

I’ve pasted both the SPROC and the Java for reference.

I keep receiving [“java.sql.DataTruncation: Data truncation”] for the sync attributes operation.

I’ve turned on ccg debugging for the VAs, and noticed there was extra whitespace in the attribute values from the result for the provisioning plan, so I added a trim(); while that trimmed it, I still receive the same [“java.sql.DataTruncation: Data truncation”] error.

I’ve been able to call this procedure through the client with no issues; however when invoked through the provisioning rule, I have the issue.

When I use either a straight SQL DML statement such as update, rather than the sproc, it works as expected.

The only thing I can think of is that create requires 18 parameters, while modify requires 17. However, I am passing a static string to the 18th parameter and the [“java.sql.DataTruncation: Data truncation”] is not what I’d expect if it was simply just a attribute not being declared for the sproc.

    log.error(\"Exit iSeries JDBC Provisioning\");
    return result;

Also, the log.error messages are not making it to the ccg.log; previously I tried log.debug, log.warn and found : What is the correct way of debugging connector rules - #18 by chirag_patel – but no luck – I wasn’t sure if I needed to import any logger libraries as well. I’ve been using another established provisioning rule as my start point and it’s been a while since I touched Java.

Does the ccg.log at least tell you that the rule was invoked?

In general, The error message “java.sql.DataTruncation: Data truncation” indicates that there is an attempt to insert or update data in a database, and the data being provided is too large to fit into the specified column in the database table.

Here are some common causes for this error:

Column Size Mismatch: The size of the data being inserted or updated exceeds the maximum size allowed for the corresponding column in the database table. Check the column definitions in the database schema and ensure that the data being passed is within the allowed size limits.
Mismatched Data Types: Ensure that the data type of the Java object being passed for insertion or update matches the data type of the corresponding column in the database. If there is a mismatch, data truncation may occur.
String Length Exceeds Column Size: If the error is related to string data, make sure that the length of the string being inserted or updated is within the allowed length of the column.
Character Encoding Issues: If dealing with character data, ensure that the character encoding of the data being passed matches the character encoding expected by the database. Mismatched character encodings can lead to data truncation.

To resolve the issue, you may need to review the code that is performing the database operation and ensure that the data being passed aligns with the database schema. Check the sizes and types of the columns, and make any necessary adjustments to ensure that the data being inserted or updated conforms to the database constraints. If necessary, you may need to increase the size of the columns in the database or modify the data being passed to fit within the specified constraints.

Thank you both for your suggestions!

Yeah, the ccg.log was picking up the invocation of the rule, I was scratching my head trying to find the logger output from the java code though, as I suspected that would be captured there.

The data truncation error was due to a miscommunication with the developer, and I was provided the wrong sproc – everything is good now with the appropriate number of parms being requested. Appreciate the replies!
