Optional Element Summary

Optional Elements

Modifier and Type	Optional Element and Description
boolean	copyOnRead Indicates whether the "copy on read" is enabled for this cache.
float	criticalHeapPercentage Configures the percentage of heap at or above which the cache is considered in danger of becoming inoperable.
boolean	enableAutoReconnect By default, a GemFire member (both locators and servers) will attempt to reconnect and reinitialize the cache after it has been forced out of the distributed system by a network partition event or has otherwise been shunned by other members.
float	evictionHeapPercentage Configures the percentage of heap at or above which the eviction should begin on Regions configured for HeapLRU eviction.
String	locators Configures the list of GemFire Locators defining the cluster to which this GemFire cache data node should connect.
int	lockLease Configures the length, in seconds, of distributed lock leases obtained by this cache.
int	lockTimeout Configures the number of seconds a cache operation will wait to obtain a distributed lock lease.
String	logLevel Configures the log level used to output log messages at GemFire cache runtime.
int	messageSyncInterval Configures the frequency (in seconds) at which a message will be sent by the primary cache-server to all the secondary cache-server nodes to remove the events which have already been dispatched from the queue.
String	name Configures the name of this GemFire member in the cluster (distributed system).
int	searchTimeout Configures the number of seconds a cache get operation can spend searching for a value before it times out.
boolean	useClusterConfiguration Configures whether this GemFire cache member node would pull it's configuration meta-data from the cluster-based Cluster Configuration service.

Element Detail

copyOnRead

public abstract boolean copyOnRead

Indicates whether the "copy on read" is enabled for this cache. Default is false.

Default:

false

criticalHeapPercentage

public abstract float criticalHeapPercentage

Configures the percentage of heap at or above which the cache is considered in danger of becoming inoperable.

See Also:

ResourceManager.DEFAULT_CRITICAL_HEAP_PERCENTAGE

Default:

0.0f

enableAutoReconnect

public abstract boolean enableAutoReconnect

By default, a GemFire member (both locators and servers) will attempt to reconnect and reinitialize the cache after it has been forced out of the distributed system by a network partition event or has otherwise been shunned by other members. Use this property to enable the auto-reconnect behavior. Default is false.

Default:

false

evictionHeapPercentage

public abstract float evictionHeapPercentage

Default:

"config"

messageSyncInterval

public abstract int messageSyncInterval

Configures the frequency (in seconds) at which a message will be sent by the primary cache-server to all the secondary cache-server nodes to remove the events which have already been dispatched from the queue. Default is 1 second.
