• Populates column hvr_cap_user for use in ColumnProperties {hvr_cap_user} substitutions (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Log-based capture of truncate table statements (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Multiple log-based capture jobs can capture from same database (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Capture from tables with value compression (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Capture from tables with row compression (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Log-based capture checkpointing using location property Capture_Checkpoint_Frequency (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).

HVR does not support the following capabilities on Db2 for Linux, Unix and Windows:

• Capture from Archive log files only.
• Direct access to logs on a file system.
• Log-based capture from hidden rowid/RRN column (ColumnProperties with parameter CaptureFromRowId).
• Rewind log-based capture to the beginning of currently active oldest transaction.
• Read archives from an alternative directory (location property Archive_Log_Path on the capture location).
• Trigger-based capture (location property Capture_Method=DB_TRIGGER on the capture location).

Repository Database

HVR supports Repository database on Db2 for Linux, Unix and Windows.

Integrate

HVR supports the following capabilities on Db2 for Linux, Unix and Windows:

• Integrate changes into location (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Burst integration (Integrate with parameter Method=BURST) (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Integrate with parameter BurstCommitFrequency (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Continuous integration (Integrate with parameter Method=CONTINUOUS) (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Tables without a key and without TableProperties with NoDuplicateRows for continuous integration (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Continuous integrate with parameter OnErrorSaveFailed (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• ColumnProperties with parameter SoftDelete (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Creation and update of HVR state tables (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).

HVR does not support the following capabilities on Db2 for Linux, Unix and Windows:

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

Bi-directional Replication

HVR supports the following capabilities on Db2 for Linux, Unix and Windows:

• Detection of changes made by HVR in a bidirectional channel to prevent loop-back (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5, state table needs to be created before replication starts).
• CollisionDetect with parameter TimestampColumn (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).

HVR does not support the following capabilities on Db2 for Linux, Unix and Windows:

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

Refresh and Compare

HVR supports the following capabilities on Db2 for Linux, Unix and Windows:

• hvrrefresh or hvrcompare from source location (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• hvrrefresh into target location (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Row-wise hvrrefresh into target location (option -g) (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).

Other Capabilities

HVR supports the following capabilities on Db2 for Linux, Unix and Windows:

• Call database procedure dbproc during replication jobs (AgentPlugin with parameter DbProc) (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• DbObjectGeneration with parameter IncludeSQLFile (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• International table and column names where DBMS is not configured with UTF-8 encoding (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Treat DBMS table names and columns as case sensitive if configured (location property Case_Sensitive_Names) (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Treat DBMS schema names as case sensitive if configured (location property Case_Sensitive_Names) (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
• Distinguish and support capture from 'materialized views' (Db2 for Linux, Unix and Windows from version 10.5 to version 11.5).
