Class GatewayPrms

java.lang.Object

hydra.BasePrms

hydra.GatewayPrms

public class GatewayPrms
extends BasePrms

A class used to store keys for gateway and gateway queue configuration settings. The settings are used to create instances of GatewayDescription, which are used to create gateway hubs.

The number of description instances is gated by names. For other parameters, if fewer values than names are given, the remaining instances will use the last value in the list. See $JTESTS/hydra/hydra.txt for more details.

Unused parameters default to null, except where noted. This uses the product default, except where noted.

Values of a parameter can be set to BasePrms.DEFAULT, except where noted. This uses the product default, except where noted.

Values and fields can be set to BasePrms.NONE where noted, with the documented effect.

Values of a parameter can use oneof, range, or robing except where noted, but each description created will use a fixed value chosen at test configuration time. Use as a task attribute is illegal.

Constant Field Values

names

public static java.lang.Long names

(String(s)) Logical names of the gateway descriptions. Each name must be unique. Defaults to null. Not for use with oneof, range, or robing.

alertThreshold

public static java.lang.Long alertThreshold

(int(s)) Alert threshold for each gateway queue, in milliseconds.

batchConflation

public static java.lang.Long batchConflation

(boolean(s)) Batch conflation for each gateway queue.

batchSize

public static java.lang.Long batchSize

(int(s)) Batch size for each gateway queue.

batchTimeInterval

public static java.lang.Long batchTimeInterval

(int(s)) Batch time interval for each gateway queue.

concurrencyLevel

public static java.lang.Long concurrencyLevel

(int(s)) Concurrency level for each gateway. See also orderPolicy, which can be set in the concurrent case.

diskStoreName

public static java.lang.Long diskStoreName

(String(s)) Name of logical disk store configuration (and actual disk store name) for each gateway queue, as found in DiskStorePrms.names. Required when enablePersistence is true. Can be specified as BasePrms.NONE (default).

enablePersistence

public static java.lang.Long enablePersistence

(boolean(s)) Enable persistence for each gateway queue. When true, requires setting a diskStoreName.

endpointNumPerDs

public static java.lang.Long endpointNumPerDs

(int(s)) Number of endpoints per distributed system for each gateway, chosen from available gateway hubs. Defaults to the total number of available gateway hubs outside of this hub's distributed system.

listeners

public static java.lang.Long listeners

(Comma-separated String(s)) Class names of listeners for each region. Can be specified as BasePrms.NONE. See listenersSingleton for control over instance creation.

Example: To use ClassA and ClassB for the first gateway, no listeners for the second gateway, and ClassC for the third gateway, specify: ClassA ClassB, none, ClassC

listenersSingleton

public static java.lang.Long listenersSingleton

(boolean(s)) Whether the listeners for each gateway are singletons across all actual gateways created with this description. Defaults to false.

maximumQueueMemory

public static java.lang.Long maximumQueueMemory

(int(s)) Maximum queue memory for each gateway.

orderPolicy

public static java.lang.Long orderPolicy

(String(s)) Order policy for each gateway. See concurrencyLevel.

socketBufferSize

public static java.lang.Long socketBufferSize

(int(s)) Socket buffer size for each gateway.
