HVR does not support the following capabilities on Ingres:
- Capture from Archive log files only.
- Log-based capture of DDL statements using action AdaptDDL.

- Continuous integrate with parameter OnErrorSaveFailed (Ingres from version 10.0 to version 11.2).
- Disable/enable database triggers during integrate (with parameter NoTriggerFiring) (Ingres from version 10.0 to version 11.2).
- ColumnProperties with parameter SoftDelete (Ingres from version 10.0 to version 11.2).
- Creation and update of HVR state tables (Ingres from version 10.0 to version 11.2).
- Integrate with parameter DbProc (Ingres from version 10.0 to version 11.2).
Bi-directional Replication
HVR supports the following capabilities on Ingres:
- Detection of changes made by HVR in a bidirectional channel to prevent loop-back (Ingres from version 10.0 to version 11.2).
- CollisionDetect with Log-based Capture (without parameter TimestampColumn) (Ingres from version 10.0 to version 11.2).
- CollisionDetect with Trigger-based Capture (with location property Capture_Method=DB_TRIGGER on the capture location and CollisionDetect without parameter TimestampColumn) (Ingres from version 10.0 to version 11.2).
- CollisionDetect with parameter TimestampColumn (Ingres from version 10.0 to version 11.2).
Refresh and Compare
HVR supports the following capabilities on Ingres:
- hvrrefresh or hvrcompare from source location (Ingres from version 10.0 to version 11.2).
- hvrrefresh into target location (Ingres from version 10.0 to version 11.2).
- Row-wise hvrrefresh into target location (option -g) (Ingres from version 10.0 to version 11.2).
- Disable/enable foreign keys and secondary indices during hvrrefresh (option -F) (Ingres from version 10.0 to version 11.2).
- For a table: disable/enable journaling, disable/enable unique/primary constraints, disable/enable volatile secondary indices, support main storage structure during hvrrefresh (Ingres from version 10.0 to version 11.2).
