      • getTxOwnerDumpRequestsAllowed

        @MXBeanDescription("Shows if dump requests from local node to near node are allowed, when long running transaction  is found. If allowed, the compute request to near node will be made to get thread dump of transaction owner thread.")
boolean getTxOwnerDumpRequestsAllowed()
        Shows if dump requests from local node to near node are allowed, when long running transaction is found. If allowed, the compute request to near node will be made to get thread dump of transaction owner thread.
        Returns:
        true if allowed, false otherwise.

        Sets if dump requests from local node to near node are allowed, when long running transaction is found. If allowed, the compute request to near node will be made to get thread dump of transaction owner thread.
        Parameters:
        allowed - whether to allow
