Realm Properties Details Panel

The Realm Properties details panel presents the global values of realm properties. In edit mode, you can modify the property values.

Intervals

Several intervals affect the operation of the realm server and its interaction with clients.

GUI Parameter Description
Client to Realm Server Heartbeat The realm server instructs its clients to send it heartbeats at this interval, in seconds.

Zero is a special value, instructing the clients not to send heartbeats.

Client to Realm Server Timeout When a realm server does not receive client heartbeats for this interval, the server deletes the client from list of monitored clients.
Realm Server to Client Heartbeat The realm server sends heartbeats to its clients at this interval, in seconds.

Zero is a special value, instructing the realm server not to send heartbeats.

Realm Server to Client Timeout When a client does not receive server heartbeats for this interval, it actively attempts to reconnect to a server. If the server has a fault-tolerant partner, the client can failover to that partner.
Client Sampling Interval Clients sample their operating metrics at this interval, in seconds.

Zero is a special value, instructing all clients to disable the monitoring feature.

See TIBCO FTL Monitoring.

Dynamic Message Formats

Message formats can affect network bandwidth usage.

GUI Parameter Description
Dynamic Message Formats Restrict the formats available to applications.

When enabled, the only available formats are preload formats and built-in formats. For complete information, see Message Formats Administration.

Secure Communications

The realm server can enforce TLS security in its communications with clients.

If the realm server does not use secure communications, a warning appears at the top of this section.

GUI Parameter Description
Warn about insecure transports between clients When enabled, defining any transports that use non-secure protocols triggers a validation warning.

(This validation warning can trigger even if the realm server does not enforce TLS communications.)

TLS Cipher Suites Replace default ciphers and protocols.
Warning: Do not change these values unless explicitly instructed to do so by TIBCO.

In the event that a flaw is discovered in the default cipher suite or protocols, TIBCO will issue a security announcement, and indicate new values for these settings.

TLS Context Options

Persistence

Persistence operations

GUI Parameter Description
Persistence Retry Persistent publisher operations, subscriber operations, and map operations require access to the persistence server. When they cannot access the persistence server (usually because of network failure or quorum unavailability), they can automatically retry the interaction.
  • None The default behavior. Persistence operation calls that cannot access the persistence server raise an exception.
  • Unlimited Persistence operation calls retry the interaction indefinitely. Calls return only upon success.

Properties of individual publishers, subscribers, and map objects within application programs supersede this global setting.

Subscription Statistics

You can control whether clients and services collect fine-grained monitoring metrics about subscriptions and message substreams. These metrics produce a large volume of monitoring data.

GUI Parameter Description
Collect Subscription Statistics When enabled, clients gather monitoring metrics about subscriptions and message substreams, and send them to the realm server.

When disabled, clients do not gather these metrics.
