This documentation is for an older version of HVR.
Capabilities for HANA
This section lists the Capabilities of HVR when using 'HANA'. For more information about the pre-requisites, access privileges, and other configuration requirements, see Requirements for HANA.
Capture
HVR supports the following capabilities on HANA:
- Capture changes from location (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Log-based capture (capture from DBMS logging system) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Capture from Archive log files only (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Log-based capture of tables without a primary key (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Direct access to logs on a file system (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Log-based capture of tables with LOB column (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Log-based capture from hidden rowid/RRN column (ColumnProperties /CaptureFromRowId) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Rewind log-based capture to specific time (Hvrinit option -i) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Online refresh using accurate LSN/SCN (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Multiple log-based capture jobs can capture from same database (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Read archives from an alternative directory (Capture /ArchiveLogPath) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
HVR does not support the following capabilities on HANA:
- Log-based capture of DDL statements using action AdaptDDL.
- Access to logs using SQL interface.
- Rewind log-based capture to the beginning of currently active oldest transaction.
- 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.
- Log-based capture checkpointing (action Capture /CheckpointingFrequency).
- Hvrlogrelease to preserve journal/archives.
- Trigger-based capture (action Capture /TriggerBased).
Hub Database
HVR does not support Hub database on HANA.
Integrate
HVR supports the following capabilities on HANA:
- Integrate changes into location (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Integrate with /Burst (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Integrate with /BurstCommitFrequency (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Continuous integration (Integrate without /Burst) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Action Transform /SoftDelete (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Bulk load requires a staging area (LocationProperties /StagingDirectoryHvr) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Creation and update of HVR state tables (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
HVR does not support the following capabilities on HANA:
- Action TableProperties with /DuplicateRows for continuous integration.
- Continuous Integrate with /OnErrorSaveFailed (without /Burst).
- Disable/enable database triggers during Integrate (/NoTriggerFiring).
- Integrate with /DbProc.
Bi-directional Replication
HVR supports the following capabilities on HANA:
- Detection of changes made by HVR in a bidirectional channel to prevent loop-back (HANA from version 1.0 SPS 11 to version 2.0 SPS 05, state table needs to be created before replication starts).
- CollisionDetect with /TimestampColumn (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
HVR does not support the following capabilities on HANA:
- CollisionDetect with Log-based Capture (without /TimestampColumn).
Refresh and Compare
HVR supports the following capabilities on HANA:
- Hvrrefresh or Hvrcompare from source location (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Hvrrefresh into target location (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Row-wise Hvrrefresh into target location (option -g) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
Other Capabilities
HVR supports the following capabilities on HANA:
- Call database procedure dbproc during replication jobs (action AgentPlugin /DbProc) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- International table and column names where DBMS is not configured with UTF-8 encoding (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
- Treat DBMS table names and columns as case sensitive if configured (action LocationProperties /CaseSensitiveNames defined) (HANA from version 1.0 SPS 11 to version 2.0 SPS 05, since HVR 5.6.5/1).
- Distinguish and support capture from 'column store tables' (HANA from version 1.0 SPS 11 to version 2.0 SPS 05).
HVR does not support the following capabilities on HANA:
- Use distribution key for parallelizing changes within a table (ColumnProperties /DistributionKey).
- Lossless binary float datatypes. No dataloss when transporting float values (because base 2 fractions are never converted to base 10).
- Distinguish and support capture from 'row store tables'.
