The October 2026 release of Data Integration includes the following changed behaviors.
Fixed-width file formats
This release includes the following behavior changes for fixed-width file formats:
•When you configure column widths, you enter the width for each field that you add.
Previously, you specified the column boundaries as a comma separated list or marked column boundaries on a ruler.
•You configure the default date format in the Date Format dialog box where you select the field width type, enter the width, and enter the datetime format.
Previously, you entered the default date format as a single text string.
•You configure field metadata in the Fields section on the Fixed-Width File Format page.
Previously you configured field metadata in the Edit Columns dialog box.
•You configure additional attributes for the fixed-width file format in the Advanced Properties section on the Fixed-Width File Format page.
Previously you configured additional attributes in the Additional Attributes dialog box.
•Several advanced properties have been renamed:
- Line Sequential is now Process File Line-by-Line.
- Number of Rows to Skip is now Rows to Skip at Start
- Number of Bytes to Skip After Column Ending is now Bytes to Skip After Field
- Null Character Type is now Null Value Type
- Null Character is now Null Value Character
- Repeat Null Character is now Use Repeated Null Character
- Strip Trailing Blanks is now Remove Trailing Spaces
For more information, see Components.
Functions in advanced mode
This release includes the following behavior changes for functions in advanced mode:
MAKE_DATE_TIME
If you pass a null value to the MAKE_DATE_TIME function in advanced mode, the function returns NULL.
Previously, the function failed.
TO_DATE
If you pass an invalid date to the TO_DATE function in advanced mode, the function returns NULL.
Previously, the function returned the next valid date.
For more information about functions in advanced mode, see Function Reference.
Git repository verification
When you use GitHub, GitLab, or Bitbucket for source control, IDMC saves a local copy of the repository. To ensure that the correct repository is used, IDMC now verifies that the saved copy matches the repository that you request during a source control operation.
Previously, IDMC didn't perform verification, so IDMC could use a cached repository that didn't match your repository.
After the October 2026 upgrade, the first time you connect to a repository that was saved before the upgrade, IDMC creates a fresh copy instead of reusing the cached repository. This process can take extra time depending on the size of the repository and your network speed. Subsequent connections use the new copy as usual. IDMC doesn't delete the old saved copies automatically. Administrators can clear the old copies from the cache to free up disk space.
Intelligent Structure Models
When you create an intelligent structure model, Intelligent Structure Discovery generates normalized hierarchy relationships by default. This method generates output groups for each repeating element and provides faster performance and lower memory consumption. However, you can select a different option to generate output groups based on your requirement.
Previously, Intelligent Structure Discovery used the Default output groups option, which generated normalized or denormalized output groups.
For more information, see Components.
Taskflows
You can view the taskflow execution details on the Monitor page with read permission. You can view the history, run status, timestamps, duration, step-level breakdowns, error messages, logs, and statistics.
This change allows administrators to grant the permissions to operations teams, data governance officers, and auditors who need to monitor taskflows without the authority to trigger or modify them.
Previously, you needed the execute permission to view the taskflow execution details.
