      • ENDPOINT_GROUP_NUM_THREADS_PROPERTY

        public static final java.lang.String ENDPOINT_GROUP_NUM_THREADS_PROPERTY
        The name of the system property that can be set to specify the number of threads to use for the async endpoint group. The number should be an integer greater than zero. If this property is not set, the async endpoint group uses twice the number of available processors as determined by calling Runtime.availableProcessors().

      • getStore

        public static KVStore getStore​(KVStoreConfig config)
                                throws FaultException
        Get a handle to an existing KVStore. Note that the KVStore itself can only be created via the KV administration console or API. The application must invoke KVStore.close(), when it is done accessing the store, to free up resources associated with the handle.
        Parameters:
        config - the KVStore configuration parameters.
        Throws:
        java.lang.IllegalArgumentException - if an illegal configuration parameter is specified.
        FaultException

      • getStore

        public static KVStore getStore​(KVStoreConfig config,
                                       LoginCredentials creds,
                                       ReauthenticateHandler reauthHandler)
                                throws FaultException
        Get a handle to an existing KVStore, with optional authentication arguments for accessing a secure KVStore instance. Note that the KVStore itself can only be created via the KV administration console or API. The application must invoke KVStore.close(), when it is done accessing the store, to free up resources associated with the handle.

        If no LoginCredentials are provided in this call, this method will attempt to locate credentials through other sources, in the following search order.

        1. KVStoreConfig.getLoginProperties()
        2. A login file referenced by the oracle.kv.security Java system property.

        Parameters:
        config - the KVStore configuration parameters.
        creds - the KVStore user login credentials. If null, the KVStore client will attempt to locate credentials based on Java system properties.
        reauthHandler - an optional re-authentication handler to be used in the event a login session expires and must be renewed. If both creds and reauthHandler are null, but login information is located using either of the above lookup methods, an internally-supplied reauthentication handler is automatically provided which will re-read login credentials as needed for reauthentication. User passwords are not retained in memory by the KVStore client, so if you explicitly provide LoginCredentials, you are also responsible for supplying a reauthentication handler, if desired.
        Throws:
        java.lang.IllegalArgumentException - if an illegal configuration parameter is specified.
        FaultException
