Property

Value

ClusterType

DYNAMIC, REPOSITORY, or LEGACY.

DYNAMIC will use multicast messaging and automatically find other nodes in the cluster. REPOSITORY is an extension of DYNAMIC where multicast messaging doesn't work. LEGACY is the default, and will use web services to communicate with a defined list of cluster nodes.

BroadcastConfiguration

A JGroups configuration file. This allows for a custom Jgroups configuration to be used in environments where multicast networking is not available. This is for DYNAMIC mode only and is optional. By default, JGroups will use the configuration defined in udp.xml.

ServiceUser

User that will validate the web service connection to other nodes. For LEGACY mode only.

ServicePassword

Password for the ServiceUser. For LEGACY mode only.

ServicePasswordEncrypted

True/False.
Is the contents of the ServicePassword encrypted.

ServiceAddress

Address of the Yellowfin web service. For LEGACY mode only.

ServicePort

Port on which Yellowfin is running. For LEGACY mode only.

ClusterHosts

This is a comma-separated list of all nodes in the cluster. These can include IP addresses or hostnames. For LEGACY mode only.

SerialiseWebserviceSessions

True/False.

This is required if using single sign-on on the cluster. It can serialise tokens to the database so that the token can be accessed from any node.

CheckSumRows

True/False.

Security option to check sum the serialised web service session records in the database. This helps prevent modification to the table which could lead to the creation of unauthorized sessions in Yellowfin.

EncryptSessionId

True/False.

Security option to encrypt the serialised web service session id in the database. This helps prevent modification to the table which could lead to the creation of unauthorized sessions in Yellowfin.

EncryptSessionData

True/False.

Security option to encrypt the serialised web service session records in the database. This helps prevent modification to the table which could lead to the creation of unauthorized sessions in Yellowfin.

AutoTaskDelegation

True/False.

This is only for DYNAMIC and REPOSITORY mode and is optional.

When enabled, the cluster will automatically assign a “master” node which coordinates background task execution. When this is turned on, you do not need to manually configure a node to run background tasks. The master node also runs system tasks, provided they have not been explicitly disabled.

When AutoTaskDelegation is disabled, each node operates like a LEGACY node. A specific node has to be designated for background task execution. This mode is not recommended.

This option is only for DYNAMIC and REPOSITORY modes.

It is a comma-separated list of task types which can run on the node. If this is not specified, the node will not run any background tasks.

Available types are specified here.

This option is only for DYNAMIC and REPOSITORY modes.
It is a comma-separated list of numbers, which indicates how many tasks of each type (specified in TaskTypes), can concurrently run on the node. Each value specified in this list has a one-to-one mapping to values in the TaskTypes parameter. TaskTypes which do not have a corresponding count, are ignored.

SessionReplication

True/False.

Set this to true if container-level session replication is enabled. This will modify the logic used for destroying sessions in a cluster.

RepositoryDiscovery

True/False

This option is for DYNAMIC mode only. This enables RepositoryDiscovery on builds prior to the REPOSITORY mode being supported. REPOSITORY mode is an alias for DYNAMIC mode with RepositoryDiscovery enabled.
