This section lists the Capabilities of HVR when using 'Sybase ASE'. For more information about the pre-requisites, access privileges, and other configuration requirements, see Requirements for Sybase ASE.

Capture

HVR supports the following capabilities on Sybase ASE:

• Capture changes from location (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).

• Log-based capture of tables without a primary key (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Direct access to logs on a file system (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Online refresh using accurate LSN/SCN (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Multiple log-based capture jobs can capture from same database (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Log-based capture checkpointing (action Capture /CheckpointingFrequency) (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).

HVR does not support the following capabilities on Sybase ASE:

• Log-based capture of tables with LOB column.
• Log-based capture from hidden rowid/RRN column (ColumnProperties /CaptureFromRowId).
• Rewind log-based capture to specific time (Hvrinit option -i).
• Populates column hvr_cap_user for use in ColumnProperties {hvr_cap_user} substitutions.
• Log-based capture of truncate table statements.
• Capture from tables with basic compression.
• Hvrlogrelease to preserve journal/archives.
• Read archives from an alternative directory (Capture /ArchiveLogPath).
• Trigger-based capture (action Capture /TriggerBased).

Hub Database

HVR does not support Hub database on Sybase ASE.

Integrate

HVR supports the following capabilities on Sybase ASE:

• Integrate changes into location (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Integrate with /Burst (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Integrate with /BurstCommitFrequency (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Continuous integration (Integrate without /Burst) (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Action TableProperties with /DuplicateRows for continuous integration (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Continuous Integrate with /OnErrorSaveFailed (without /Burst) (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Action Transform /SoftDelete (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Creation and update of HVR state tables (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).

HVR does not support the following capabilities on Sybase ASE:

• Disable/enable database triggers during Integrate (/NoTriggerFiring).
• Integrate with /DbProc.

Bi-directional Replication

HVR does not support Detection of changes made by HVR in a bidirectional channel to prevent loop-back on Sybase ASE.

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 SP03).
• Hvrrefresh into target location (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Row-wise Hvrrefresh into target location (option -g) (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).
• Select data from each table from same consistent moment in time using a single transaction (and session) with 'serializable' SQL isolation level (Hvrrefresh option -Mserializable) (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).

HVR does not support the following capabilities on Sybase ASE:

• Select more than 4 billion rows during Hvrrefresh or Hvrcompare.

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 SP03).
• Treat DBMS table names and columns as case sensitive if configured (action LocationProperties /CaseSensitiveNames defined) (Sybase ASE from version 16.0 SP00 to version 16.0 SP03).

HVR does not support the following capabilities on Sybase ASE:

• Use distribution key for parallelizing changes within a table (ColumnProperties /DistributionKey).
• Distinguish and support capture from 'materialized views'.
