• Log-based capture of tables with LOB column (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Rewind log-based capture to specific time (dssactivate option -i) (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Online refresh using accurate LSN/SCN (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Populates column dss_cap_user for use in ColumnProperties {dss_cap_user} substitutions (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Log-based capture of truncate table statements (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Multiple log-based capture jobs can capture from same database (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Log-based capture checkpointing using location property Capture_Checkpoint_Frequency (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Read archives from an alternative directory (location property Archive_Log_Path on the capture location) (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).

DSS does not support the following capabilities on Sybase ASE:

• Log-based capture from hidden rowid/RRN column (ColumnProperties with parameter CaptureFromRowId).
• Rewind log-based capture to specific time (dssactivate option -i) with Capture Method SQL.
• Rewind log-based capture to the beginning of currently active oldest transaction.
• Capture from tables with basic compression.
• Trigger-based capture (using the location property Capture_Method=DB_TRIGGER at the capture location). This method has been deprecated since 6.2.0/0..

Repository Database

DSS supports Repository database on Sybase ASE.

Integrate

DSS 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 DSS state tables (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).

DSS does not support the following capabilities on Sybase ASE:

• Append integration into TimeKey (Integrate with parameter Method=APPEND).
• Disable/enable database triggers during integrate (with parameter NoTriggerFiring).
• Integrate with parameter DbProc.

Bi-directional Replication

DSS supports the following capabilities on Sybase ASE:

• Detection of changes made by DSS 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).

DSS does not support the following capabilities on Sybase ASE:

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

Refresh and Compare

DSS supports the following capabilities on Sybase ASE:

• dssrefresh or dsscompare from source location (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• dssrefresh into target location (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Isolated table dssrefresh (option -i) into target location (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
• Row-wise dssrefresh into target location (option -g) (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).

DSS does not support the following capabilities on Sybase ASE:

• Select more than 4 billion rows during dssrefresh or dsscompare.

Other Capabilities

DSS 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).
• Treat DBMS table names and columns as case sensitive if configured (location property Case_Sensitive_Names) (Sybase ASE from version 16.0 SP00 to version 16.0 SP04).
