Distributing nonce caching to servers in a cluster

Distributed nonce caching enables you to distribute the cache for a nonce to different servers in a cluster.

Before you begin

Before configuring distributed nonce caching, configure cache replication.

About this task

In previous releases of WebSphere® Application Server, the nonce was cached locally. To use this feature, you must complete the following actions:

Procedure

  1. Verify that you created an appropriate domain setting when you form a cluster.
  2. Verify that replication domain is properly secured. The nonce cache is crucial to the integrity of the nonce validation process. If the nonce cache is compromised, then you cannot trust the result of the validation process.
  3. In the administrative console for the server level, select the Distribute nonce caching option. You can enable the option by completing the following steps:
    1. Click Security > Web services.
    2. Select the Distribute nonce caching option.
  4. Restart the servers within your cluster.

Results

When you select the Distribute nonce caching option in the administrative console, the nonce is propagated to other servers in your environment. However, the nonce might be subject to a one-second delay in propagation and subject to any network congestion.

What to do next
