• Rewind log-based capture to the beginning of currently active oldest transaction.
• Capture from tables with basic compression.
• Trigger-based capture (location property Capture_Method=DB_TRIGGER on the capture location).

Integrate

HVR supports the following capabilities on Sybase ASE:

• Integrate changes into location (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Burst integration (Integrate with parameter Method=BURST) (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Integrate with parameter BurstCommitFrequency (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Continuous integration (Integrate with parameter Method=CONTINUOUS) (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Tables without a key and without TableProperties with NoDuplicateRows for continuous integration (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Continuous integrate with parameter OnErrorSaveFailed (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• ColumnProperties with parameter SoftDelete (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Creation and update of HVR state tables (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).

HVR does not support the following capabilities on Sybase ASE:

• Integrate with parameter DbProc.

Bi-directional Replication

HVR supports the following capabilities on Sybase ASE:

• Detection of changes made by HVR in a bidirectional channel to prevent loop-back (Sybase ASE from version 16.0 SP00 to version 16.0 SP04, state table needs to be created before replication starts).
• CollisionDetect with parameter TimestampColumn (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).

HVR does not support the following capabilities on Sybase ASE:

• CollisionDetect with Log-based Capture (without parameter TimestampColumn).

Refresh and Compare

HVR supports the following capabilities on Sybase ASE:

• hvrrefresh or hvrcompare from source location (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• hvrrefresh into target location (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Row-wise hvrrefresh into target location (option -g) (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).

Other Capabilities

HVR supports the following capabilities on Sybase ASE:

• International table and column names where DBMS is not configured with UTF-8 encoding (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
