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
- Verify that you created an appropriate domain setting when you
form a cluster.
- 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.
- In the administrative console for the server level, select the Distribute
nonce caching option. You can enable the option by completing
the following steps:
- Click Security > Web services.
- Select the Distribute nonce caching option.
- 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.
