DRS Synchronization Phase 2: Incremental Synchronization

  1. Locate the task paused in DRS Synchronization Phase 1: Full Synchronization and click Resume in the Operation column.

  2. The task enters the incremental synchronization phase. If the incremental synchronization delay is less than 30s, all data is about to be synchronized. Disconnect the service system of the source Oracle database to ensure that no data is written to the source Oracle database. Wait for about 1 minute after the disconnection.

  3. Compare data. Click the task name and choose Synchronization Comparison.

    1. On the Object-Level Comparison tab, click Compare to compare synchronization objects in the source Oracle database and destination GaussDB database.

    2. On the Data-Level Comparison tab, click Create Comparison Task, select the tables whose rows to be compared, and click OK.

    3. After the comparison task is complete, click View Results to view the row comparison details.

  4. After confirming that the data is consistent in the source and destination databases, locate the task and click Stop in the Operation column to stop the DRS task.
