Release 26ai - January 2026

Bug 38365169: Generic - Minimum shared pool memory setting needed to avoid job failing at later stages

Oracle GoldenGate doesn't allow updating or increasing the shared pool memory on runtime.

Workaround

To avoid this shared memory exhaustion, you can perform one of the following solutions:

  • Allocate certain fixed percentage of total database size as shared memory pool.

  • Decrease the parallelism while data is being processed in shared memory pool. However, this can reduce the performance of Extract.

Bug 38745592: Test connection fails for Oracle 19 Container Database connection

Test connection to Oracle 19c Container Database (CDB) fails with an error, while the same connection details function successfully with other database clients.

Workaround

Use a database user created by GoldenGate.

Bug 38848546: Clicking on save icon always required two times in Mapping Configuration page

The Save icon on the mapping page requires two clicks to update the target name; the first click has no effect.

Workaround

None

Bug 38750565: Scroll not working in Pipeline Configuration Mapping tab

Occasionally, scrolling in the Pipeline Configuration Mapping tab is unresponsive.

Workaround

Refresh the browser.

Bug 38855648: Oracle-to-Oracle Database Migration: Wait time for open transactions is not handled in offline migration

The configured wait time for open transactions is not applied during offline migrations; the pipeline continues without stopping when the wait time elapses.

Workaround

Ignore the Wait Time for Open Transactions option while using the offline migration use case.

Bug 38900081 - Pipeline configuration Initial Load options Data pump label needs modification

The Initial Load Data Pump label appears in MySQL migration and replication pipelines, reflecting Oracle-specific behavior. For MySQL, existing target tables are not skipped and only data differences are loaded. This is a cosmetic issue and does not affect the functionality.

Workaround

None

Bug 38833864 - Pipeline remain in ACCEPTED state during Oracle-to-Oracle Offline/Online Database Migration or One-Way Replication

When running online or offline database migration and One-way replication between Oracle OnPrem databases, the pipeline job remains in the ACCEPTED state and does not progress. This issue occurs in the initial run and resolves on subsequent re-runs.

Workaround

Re-run the pipeline.

Bug 38898013 - Intermittent - No stop button on CDC involved pipeline when is is successfully running.

Intermittently the stop button may not appear on CDC involved pipeline monitoring page. It corrects the state on reload.

Workaround

Reload the page.

Bug 38875701 - Pipeline main page not reflecting correct status for pipelines

The main pipeline page incorrectly displays the status as Not Started for all pipelines except those marked as Failed, even after successful completion.

Workaround

Click on Reload in browser.

Bug 38905451 - Offline Migration (non Autonomous AI Database to Autonomous AI Database): Pipeline do not fail if Private Network is not selected for Database Link

During offline migration from non Autonomous AI Database to Autonomous AI Database, the pipeline remains in the Accepted state and does not fail when Database on Private Network option is not selected with Database Link as the Initial Load transfer medium.

Workaround

Always select the Database on Private Network checkbox for this use case.

Bug 38908821 - In Pipeline monitoring, failed job keeps reloading API polling, which should have stopped once the job is failed

API polling and GoldenGate Studio interface refresh continues for failed jobs in pipeline monitoring, rather than ending after job failure.

Workaround

Ignore the GoldenGate Studio interface flashing due to polling.

Bug 38910713 - End user could not navigate to Running Jobs Detail page

Sometime selecting any running pipeline on the Runtime tab makes GoldenGate Studio interface unresponsive and prevents navigation to other pages, specially when many pipelines are running simultaneously.

Workaround

Refresh the browser.

Fixed an issue where step statuses in the UI are now updated to match the API

Workaround

None.

Note:

This issue is fixed in the 26ai (23.26.1.0.0) release.

Bug 38442543 - Certain special characters are not supported in SCHEMA or table name

If special characters are used in SCHEMA or table name then you will not able to edit or save the pipeline.

Workaround

Use asterisk (*) instead of using special characters when saving the mapping.

Bug 38425814 - Exclude disappears from Mapping rules if Include *.* is deleted

If the Include *.* option is deleted from the Mapping Rules table in the Pipeline Configuration Mapping Rules tab, the user interface deletes the Exclude option instead of the Include *.* option from the user interface.

Workaround

Delete *.* mapping first to avoid this issue.

Note:

This issue is fixed in the 26ai (23.26.1.0.0) release.

Bug 38415742 - Active-Active: Could not create pipeline with connection having period in the service name

If an Active-Active pipeline is created with a period in the service name, the pipeline creation fails.

Workaround

None.

Bug 38389703 - When re-running a pipeline, the Extract and Replicat processes are shown stopped though they are actually running in Oracle GoldenGate deployment

After a pipeline is restarted, the Extract and Replicat processes are shown in stopped state although they are running in the Oracle GoldenGate deployment.

Workaround

None.

Note:

This issue is fixed in the 26ai (23.26.1.0.0) release.

Bug 38384257 - Even after stopping a job , we see stop job option

Stop button is enabled in the GoldenGate Studio user interface even though the job is initializing and the Extract/Replicat processes are not running.

None.

Bug 38314733 - User interface inconsistent with backend status while monitoring Pipelines

Pipeline page in the user interface gets stuck sometimes.

Workaround

None.

Note:

Bug 38285621 - GoldenGate Studio pipeline configuration page is stuck when source or target Oracle Autonomous AI Database is not reachable

When there are a lot of connections to an Oracle Autonomous AI Database along with multiple pipelines, GoldenGate Studio keeps on polling the jobs status APIs even when they aren't responding. This creates slowness and the system may get stuck.

Workaround

Ensure that the Oracle Autonomous AI Database is running so that the pipeline configuration page shows valid data.

Note:

This issue is fixed in the 26ai (23.26.1.0.0) release.

Bug 35927051 - Incorrect Mapping Rules for a specific mapping pattern

Mapping rules are not saved correctly when a specific mapping pattern is selected in the Mapping Rules page.

Workaround

None.

Note:

This issue is fixed in the 26ai (23.26.1.0.0) release.

Schema Mapping and Configuration

When you finish creating a pipeline by clicking on the "Save & Configure" button, you are shown the Mappings section, where all the source's schemas are listed and they all come preselected. If you use accessibility keys such as tab, shift, return, then you can't select or deselect any of the mapping options, nor display all schemas/tables for the drop down list.

Workaround

Use the mouse instead of using the accessibility keys.

Database Version Mismatch

The Initial Load step may fail if the source database version is higher than the target database version causing errors similar to the following:

  • ORA-39059: Dump file set is incomplete.

  • ORA-39246: Cannot locate master table within provided dump files.

Workaround

Before initiating replication, ensure that the target database is upgraded to at least the same version as the source database.
