IBM Db2 Database OCF Connector: Version 1.2.1¶
Fixed Issues¶
Connector Fails to Extract Foreign Keys After Metadata Extraction for Certain Schemas¶
Due to trailing white spaces in schema names, the connector fails to extract foreign keys after MDE. The issue occurs as the connector wasn’t able to resolve the referenced primary key schemas due to the schema name mismatch with foreign keys.
This issue is now resolved. (AL-165840)
CHAR(xx) Column Type from DB2 Appears As VARCHAR(xx) on Alation UI¶
The Alation user interface displays the CHAR(xx) column type from DB2 as VARCHAR(xx).
This issue is now resolved. (AL-173624)

Support for Authentication Based on AWS Secret Manager Credentials¶
When installed on an Alation Agent, the IBM Db2 OCF connector now supports authentication using credentials the Agent has fetched from AWS Secrets Manager. For more information, see AWS Secrets Manager for Data Source Authentication Using OCF Connector. (AL-166114)
Note
Support for authentication based on AWS Secret Manager is available for all installations (on-premise and Alation Cloud Service), however, integrating with AWS Secrets Manager through an Alation Agent applies only to cloud native architecture.
March 27, 2024¶
IBM Db2 Database OCF Connector: Version 2.0.3¶
Enhancements¶
Removal of ORDER BY Clause in Default Metadata Extraction Queries¶
The ORDER BY clause has now been removed from the default Metadata extraction queries.
Processes subsequent to MDE ensure the extracted objects (Schema, Table, and Column) are mapped to the correct hierarchy. Therefore, it is redundant for the connector to fetch ordered items from the data sources. (AL-149896)
Fixed Issues¶
Metadata Extraction Fails¶
Metadata extraction fails with the following redundant error message:
MissingFormatArgumentException: Format specifier ‘%s
The connector has now modified the error handling to display appropriate error messages during MDE failure. (AL-147543)
