Examples of com.sun.sgs.impl.service.data.store.cache.server.CachingDataStoreServerImpl

• com.sun.sgs.impl.service.data.store.cache.server.CachingDataStoreServerImpl
  An implementation of {@code CachingDataStoreServer}.

  The {@link #CachingDataStoreServerImpl constructor} supports the followingconfiguration properties:

  Property: {@value #DIRECTORY_PROPERTY}
  Default: ${com.sun.sgs.app.root}/dsdb

  The directory in which to store database files.

  Property: {@value #LOCK_TIMEOUT_PROPERTY}
  Default: {@value #DEFAULT_LOCK_TIMEOUT_PROPORTION} times the transaction timeout

  The maximum amount of time in milliseconds that an attempt to obtain a lock will be allowed to continue before being aborted. The value must be greater than 0, and should be less than the transaction timeout.

  Property: {@value #MAX_RETRY_PROPERTY}
  Default: {@value #DEFAULT_MAX_RETRY}

  The number of milliseconds to continue retrying I/O operations before determining that the failure is permanent. The value must be non-negative.

  Property: {@value #NUM_CALLBACK_THREADS_PROPERTY}
  Default: {@value #DEFAULT_NUM_CALLBACK_THREADS}

  The number of threads to use for performing callbacks. The value must be greater than 0.

  Property: {@value #NUM_KEY_MAPS_PROPERTY}
  Default: {@value #DEFAULT_NUM_KEY_MAPS}

  The number of maps to use for associating keys and maps. The value must be greater than 0. The number of maps controls the amount of concurrency.

  Property: {@value #RETRY_WAIT_PROPERTY}
  Default: {@value #DEFAULT_RETRY_WAIT}

  The number of milliseconds to wait before retrying a failed I/O operation. The value must be non-negative.

  Property: {@value #SERVER_PORT_PROPERTY}
  Default: {@value #DEFAULT_SERVER_PORT}

  The network port used to accept server requests. The value should be a non-negative number less than 65536. If the value specified is 0, then an anonymous port will be chosen.

  Property: {@value #TXN_TIMEOUT_PROPERTY}
  Default: The value of the {@value com.sun.sgs.impl.service.transaction.TransactionCoordinator#TXN_TIMEOUT_PROPERTY} property, if specified, or else {@value com.sun.sgs.impl.service.transaction.TransactionCoordinatorImpl#BOUNDED_TIMEOUT_DEFAULT}

  The transaction timeout in milliseconds.

  Property: {@value #UPDATE_QUEUE_PORT_PROPERTY}
  Default: {@value #DEFAULT_UPDATE_QUEUE_PORT}

  The network port used to accept requests to the server's update queue. The value should be a non-negative number less than 65536. If the value specified is 0, then an anonymous port will be chosen.

  To avoid deadlocks, the implementation needs to insure that operations that obtain multiple locks from the lock manager grab the lowest key first. In particular, the methods that obtain multiple locks are {@link #getBindingForUpdate} and {@link #getBindingForRemove}.
