Deploying cluster servers

pf.operational.mode

Controls the operational mode of the PingFederate server. PingFederate supports the following modes:

pf.cluster.node.index

Defines a unique index number for the server in a cluster. The index number is used to identify peers and optimize inter-node communication. The allowed range is 0 to 65535.

If no value is set for the node index, the system assigns an auto-generated value in the range of 0 to 2147483647.

This property has no default value. If you specify an index number, you can configure instances of the Cluster Node Authentication Selector and place them in authentication policies to customize authentication requirements based on the runtime node servicing a request.

pf.cluster.auth.pwd

Sets the password that each node in the cluster must use to authenticate when joining the cluster. This prevents unauthorized nodes from joining a cluster. The value can be any string, or blank.

All nodes in a cluster must share the same value, blank or otherwise.

pf.cluster.encrypt

Indicates whether to encrypt network traffic sent between nodes in a cluster. The possible values are true or false (default).

When set to true, communication within the cluster is encrypted with a symmetric key derived from the value of the pf.cluster.auth.pwd property.

All nodes in a cluster must have the same value for this property.

pf.cluster.encryption.keysize

The length of the key that PingFederate takes into consideration when deriving the symmetric key from the value of the pf.cluster.auth.pwd property for the purpose of encrypting network traffic sent between nodes in a cluster. Required only when the pf.cluster.encrypt is set to true.

All nodes in a cluster must have the same value set for this property.

The default value is 128.

pf.cluster.bind.address

Defaults to NON_LOOPBACK, which leaves the system to choose an available non-loopback IP address. Alternatively, enter an IP address of the network interface to which the cluster communication should bind. For machines with more than one network interface, provide a specific IP address.

You can use this property to increase performance (particularly with UDP) and improve security by segmenting cluster-communication traffic onto a private network or VLAN.

pf.cluster.bind.port

Specifies the port associated with the pf.cluster.bind.address property or with the default network interface used.

This is the port used by other cluster members during their discovery process, usually via the pf.cluster.tcp.discovery.initial.hosts property.

The default value is 7600.

pf.cluster.failure.detection.bind.port

Indicates the bind port of a server socket that is opened on the given node and used by other nodes as part of the cluster’s failure-detection mechanisms. If set to 0 or unspecified, a random available port is used. The default value is 7700.

pf.cluster.transport.protocol

Indicates the transport protocol used for cluster communication. Values are udp or tcp. The default value is tcp. All nodes in a cluster must have the same value set for this property.

Use UDP when IP multicasting is enabled in the network environment and the majority of cluster traffic is point-to-full-group. You must also configure both the pf.cluster.mcast.group.address and pf.cluster.mcast.group.port properties.

Use TCP for geographically dispersed servers or when multicast is not available or disabled for some other reason. For example, when using routers that do not support multicast messaging. TCP may also be appropriate if your cluster configuration employs more point-to-point or point-to-few messaging than point-to-group.You must also configure the pf.cluster.tcp.discovery.inital.hosts property.

pf.cluster.mcast.group.address

Defines the IP address shared among nodes in the same cluster for UDP multicast communication; required when UDP is set as the transport protocol. The valid range is 224.0.0.0 to 239.255.255.255. Some addresses in this range are reserved for other purposes. This property is not used for TCP.

All nodes in a cluster must have the same value set for this property.

The default value is 239.16.96.69.

pf.cluster.mcast.group.port

Defines the port in conjunction with the pf.cluster.mcast.group.address property value. This property is not used for TCP configurations.

All nodes in a cluster must have the same value set for this property.

The default value is 7601.

pf.cluster.tcp.discovery.initial.hosts

Designates a static list of PingFederate servers to be contacted for cluster membership information when discovering, joining, and rejoining the cluster. This value is required when TCP is set as the transport protocol. The value is a comma-separated list of host names (or IP addresses) and their cluster bind ports, for example, host1[7600],10.0.1.4[7600],host7[1033],10.0.9.45[2231].

When using static discovery, add at least one node for the cluster to know in advance. This property should contain all nodes in the cluster (including itself) to increase the likelihood of new members finding and joining the cluster.

When using dynamic discovery, leave this property blank and enable dynamic discovery in the <pf_install>/pingfederate/server/default/conf/tcp.xml file. For more information, see Enabling dynamic discovery for clustering.

pf.cluster.adaptive

Indicates whether runtime state-management services should use the adaptive clustering architecture.

The default value is true for new installations and false for upgrades.

pf.cluster.diagnostics.enabled

false turns off JGroups diagnostics. true turns it on.

The default value is false.

pf.cluster.diagnostics.addr and pf.cluster.diagnostics.port

The multicast address and port this node listens on for diagnostic messages.

The default values are 224.0.75.75 and 7500, respectively. Do not change the default values.

node.tags

Defines the tags associated with this node.

Configuration is optional. When configured, PingFederate considers this property when processing requests. For example, you can use tags to determine the datastore location that this PingFederate node communicates with. You can also use tags in conjunction with authentication selectors and policies to define authentication requirements.

You can specify one tag.

You can also specify a list of prioritized, space-separated tags.

Tags cannot contain spaces.

pf.cluster.thread.pool.max.threads

The maximum number of threads in the JGroups thread pool responsible for processing received remote procedure calls (RCPs).

For this property to take effect, one of the following files must be up to date:

The default value is 40.
