Load, Replicate, Stop, Suspend and Resume.
Before you select any application table, the initial load of the tables DD02L, DD02T & DD08L must be completed as they contain the metadata information.
Load:
Starts an initial load of replication data from the source system. The procedure is a one-time event. After it is completed, further changes to the source system database will not be replicated.
For the initial load procedure, neither database triggers nor logging tables are created in the source system. Default settings use reading type 3 (DB_SETGET) with up to 3 background jobs in parallel to load tables in parallel or subsequently into the HANA system.
Replicate:
Combines an initial load procedure and the subsequent replication procedure (real time or scheduled).
Before the initial load procedure will start, database trigger and related logging table are created for each table in the source system as well as in SLT replication server.
Stop Replication:
Stops any current load or replication process of a table.
The stop function will remove the database trigger and related logging tables completely. Only use this function if you do want to continue a selected table otherwise you must initially load the table again to ensure data consistency.
Suspend:
Pauses a table from a running replication. The database trigger will not be deleted from the source system. The recording of changes will continue and related information is stored in the related logging tables in the source system.
If you suspend tables for a long time the size of logging tables may increase and adjust the table space if required.
Resume:
Restarts the application for a suspended table. The previous suspended replication will be resumed (no new initial load required).
