database if you want to run in a cluster. Please see the <<_database,database configuration>> section of this guide for more information.

be clustered without multicast, but this requires a bunch of configuration changes. Please see

|
|
|
the <<_clustering,clustering>> section of this guide for more information.

|
* On Linux, it is recommended to use `/dev/urandom` as a source of random data to prevent {project_name} hanging due to lack of available

entropy, unless `/dev/random` usage is mandated by your security policy. To achieve that on Oracle JDK 8 and OpenJDK 8, set the `java.security.egd`

system property on startup to `file:/dev/urandom`.
