Select the Options for Replication

After you select the source and target LUNs, you can set various options for the replication pairs that are controlled by the protection plan.

1. (Asynchronous replication) Click the Secure data transfer from Primary Replication Engine to Secondary Replication Engine checkbox.
2. Specify the number of concurrent pairs to resynchronize in the Batch Resync field.
3. To automatically resynchronize your protection plan, in the event that a resynchronization is necessary, set the time frame in the Start automatic resync field.
   Example: Choose a time that has minimal impact on system resources. For example, during off hours or after business hours.
   Note: Not setting a time frame will require manual intervention if the protection plan requires resynchronization.
4. Verify the Sync options.
   Depending on the type of replication, the system automatically selects the sync option:
   • Direct Copy for synchronous replication
   • Fast Copy for asynchronous replication
5. (Asynchronous replication) Select the Compression option.
   Valid options:

   • Disable

   • Enable

6. Set the Resync File Threshold. In most cases, the default setting of 16 GB (16,384 MB) is sufficient.
   Note: Setting the Resync File Threshold too high might have a negative impact on available Replication Engine resources. Setting the threshold too low might result in increased recovery point objective (RPO) times during high data loads.
7. Set the RPO Threshold to limit on how much data can be in the source Replication Engine cache before switching from data mode to metadata mode.
   When the pair falls behind synchronous mode, the Replication Engine starts sending alerts to the administrator.
8. (Optional) Set the Differential File Threshold as directed by Oracle Customer Support. In most cases, the default setting of 64 GB (65,536 MB) is sufficient.
