Data replication domain settings
Use this page 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.

Environment | Replication domains | replication_domain_name
- Name
- Specify a name for the replication domain. The name must be unique within the cell.
- Request timeout
- Specify 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
Timeype of encryption to use when transferring replicated data to another area of the network. Select NONE if you don't want to use encryption, DES if you want to use data encryption standard, or 3DES if you want 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 you 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 console and click Regenerate encryption key to regenerate this key. Periodically regenerating the key enhances security.
Data type String Default NONE
- Number of replicas
- Specify the number of replicas that are created for every entry or piece of data that is replicated in the replication domain.
Single replica One replica is created. This is the default value. Full group replica Each object is replicated to every appserver that is configured as a consumer of the replication domain. Specific number of replicas A custom number of replicas for any entry that is created in the replication domain.
