Data replication domain settings
To configure a data replication domain. Use data replication domains to transfer data, objects, or events for session manager, dynamic cache, or stateful session beans among the appservers in a cluster.
To view this admin console page, click...
Environment | Replication domains | replication_domain_name
- Name
-
Name for the replication domain. The name must be unique within the cell.
- Request timeout
-
How long a replication domain consumer waits when requesting information from another replication domain consumer before it gives up and assumes the information does not exist.
Units seconds Default 5 seconds - Encryption type
-
Type of encryption to use when transferring replicated data to another area of the network.
Select NONE if we don't want to use encryption, DES to use data encryption standard, or 3DES to use triple DES. The default is NONE.
The DES and 3DES options encrypt data sent between appserver processes (for example, session manager and dynamic caching). Encrypting data improves the security of the network that joins the processes.
If we select DES or 3DES, after you click Apply or OK, a key for global data replication is generated. At regular intervals, for example once each month, you should navigate to this page in the admin console and click Regenerate encryption key to regenerate this key. Periodically regenerating the key enhances security.
Data type String Default NONE - Number of replicas
-
Number of replicas that are created for every entry or piece of data that is replicated in the replication domain.
Single replica Every HTTP session is replicated to exactly one other appserver. This is the default value. Entire domain Each object is replicated to every application server configured as a user of the replication domain. Specify Specify the number of replicas that to create for each HTTP session.
