Configuring memory-to-memory replication for the peer-to-peer function with a local replicator (default memory-to-memory replication)

Why and when to perform this task

To configure the session management facility for memory-to-memory session replication for peer-to-peer functions (both client and server function, or both mode) with a local replicator and no partitioning, complete the following steps:

Steps for this task

  1. Create an application cluster.
    This cluster is used to deploy the application.
    1. Go to the Server Cluster page. Click Servers > Clusters.
    2. Click New.
    3. Type a cluster name for this application cluster.
    4. Define a replication domain. Select the Create Replication Domain for this cluster check box.
    5. Click Next.
    6. Define each cluster member server. Type a cluster member name.
    7. Select the Create Replication Entry in this Server check box.
      This step adds a replicator into this new server.
    8. Click Apply.
      Repeat steps f through h for each server created in this cluster.
    9. Click Next and review the summary of changes.
    10. Click Finish to complete the configuration.
    You have now created a cluster that contains the deployed application and the replication domain.
  2. Enable memory-to-memory session replication for each server.
    1. Go to the appropriate level of session management for the Web container level. Click Application Servers > server_name > Web Container > Session Management
    2. Click Distributed Environment Settings under Additional Properties.
    3. If a replicator has been created and is associated with this or another server, select Memory to Memory Replication.
      If no replicator is already created for any server, a note appears stating this. In this case, click Memory to Memory Replication. The Internal Replication Domain panels appear. These panels lead you through the process of creating a replication domain and a replicator. After you create a replication domain and a replicator, begin again with step 2a.
    4. Click Apply.
    5. Repeat these steps for each server. Click OK.
  3. If you want to change the tuning parameters, click Custom Tuning Parameters and select a setting or customize one.

    Note: Using the default tuning parameter custom settings, which specifies time based write interval of 10 seconds, may result in data loss when an application server in your cluster fails. However, this is just a small opportunity for lost data when compared to the significant improvement in performance.

    1. Click Apply.
    2. Click Save.
