IBM Enterprise Console manual GatewayQueueSize, GatewaySendInterval, GatewayTMEAckEnabled

acknowledgement from the event server. The default value is 30 seconds. This keyword works with the GatewayTMEAckEnabled keyword for event delivery.

GatewayQueueSize

Specifies, in bytes, the size for the buffers containing events waiting to be forwarded to event servers. If any of these buffers fill before the expiration of the GatewaySendInterval option, the waiting events are immediately sent.

The default is 40 000 bytes.

GatewaySendInterval

Specifies, in seconds, the interval to forward events to event servers. The gateway holds events when they are received, and then bundles them up and forwards them in a message to the appropriate event server when this interval expires.

The default is five seconds.

GatewayTMEAckEnabled

When set to YES, connection-oriented, TME connections expect an acknowledgement from the event server before the gateway discards the sent events. Use this keyword to ensure the event delivery. The default value is NO.

MaxGWCacheSizeMegs

Specifies the maximum size in megabytes that the cache file can grow to. By default, the maximum size of the cache is 1 MB. The keyword does not appear in the configuration file.

RetryInterval When events cannot be sent to an event server, the gateway waits the specified number of seconds before connecting to a secondary server. While the gateway is waiting for the expiration of this interval, new events continue to be received by the gateway and are buffered in memory (and cached to disk as necessary). You can adjust the size of the gateway memory queues for adapters with the GatewayQueueSize keyword.

The RetryInterval option allows adapters to send all events to the primary event server even if the primary event server is stopped briefly, such as when loading a new rule base. If you use this option to wait for the restarting of an event server, set the value for a period of time longer than needed for the event server to be stopped and restarted.

The RetryInterval keyword is optional.

ServerLocation

Specifies a default event server location to be used if adapters do not specify a server location in an event instance. If ServerLocation is specified in the configuration file for an adapter, that location is passed from the adapter to the gateway as part of the event, and the gateway forwards the event to the adapter-specified event server. If ServerLocation is not specified in an adapter configuration file, the gateway sends the events for that adapter to the event server specified with the ServerLocation keyword. If ServerLocation is not specified in the gateway configuration file, the gateway sends the event to the event server in the local Tivoli management region.
