Configure cache replication

 

Overview

Cache replication leverages the WebSphere internal replication service that is also leveraged for HttpSession memory-to-memory replication for failover purposes. Hence, a replication domain with at least one replicator entry needs to exist in order to replicate the data. The dynamic cache service, in essence, connects to the replicator. See more information in the topic referring to managing internal replication.

To configure cache replication and its features:

  1. Click Servers > Application Servers in the administrative console navigation tree.

  2. Click server.

  3. Click Dynamic Cache Service.

  4. Select the Enable cache replication check box in the Cache replication field.

    To manage batch update or PUSH-PULL - PUSH/PULL, repeat steps 1-4, then click the Enable cache replication link to the right of the Enable cache replication check box. Batch update interval is set under push frequency. PUSH-PULL-PUSH/PULL is set through the runtime mode.

    You can also select which replication domain and initial replicator entry the dynamic cache will utilize (either those managed within the cell or across the cell).
