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 application servers in a cluster.
To view this administrative console page, click Environment > Replication domains > replication_domain_name.
Specifies a name for the replication domain. The name must be unique within the cell.
- Request timeout
Specifies 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
Specifies the type of encryption to use when transferring replicated data to another area of the network. The options are NONE, DES, and DES3. The default is NONE. The DES and DES3 options encrypt data sent between application server processes (for example, session manager and dynamic caching) to better secure the network joining the processes.
If you specify DES or DES3, a key for global data replication is generated after you click Apply or OK. If you use the DES or DES3 encryption type, click Regenerate encryption key at regular intervals, for example once each month. 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 One replica is created. This is the default value. Full group replica Each object is replicated to every application server 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.
Multi-broker replication domains
