A method and a system for the evacuation of buildings providing an elevator system includes at least one elevator car and an elevator shaft. The system includes a device to detect an incident or a device to receive an emergency signal in this regard, a device for determining the floor of this incident, and at least one sealing element (positioned in the elevator shaft and constructed to seal the elevator shaft, so that the elevator shaft is divided in at least two sections.

Embodiments relate to a method, system, and computer program product for data management. An aspect includes a search index that is created for a database. The search index has a reference value of a first or a second type associating data to a storage location in a first memory or a second memory respectively. Responsive to a data retrieval request, data is accessed using the reference value from the first or the second memory. If there is a data migration between the first and second memory storage, the reference values are then recalculated and altered in the search index accordingly.

A destination call-giving device for giving destination calls in an elevator system includes a device available to a user for selecting a destination floor from a plurality of floors that are in a certain sequence, and an output for communicating the selected destination floor to the control system of the elevator system. The device for selecting a destination floor includes a touch-sensitive display forming a user interface for presenting to the user information related to the selection of a destination floor and for receiving the input of the user. The destination floor is arranged to be selectable by the user from the aforementioned plurality of floors by moving a touch-sensitive point on a touch-sensitive display.

A method, and corresponding computer program product and computer system, for replicating a database image in a distributed database environment comprises: defining a checkpoint image of the primary node including a database structure and a plurality of database pages; creating a replica database by initiating a backup node and saving the defined structure on the initiated backup node; sending each database page of the checkpoint image for saving on the backup node; saving every transaction on the primary node and creating a corresponding REDO transaction; identifying each data page operated on by each REDO transaction; sending each created REDO transaction to the backup node in the order in which the corresponding transaction occurred, and prioritizing each identified database page so that it arrives at the backup node before or substantially at the same time as a corresponding REDO transaction.

Replication for on-line hot-standby database

Providing an index for a database table that includes a first portion of rows stored in a memory device and a second portion of rows stored in a disk device. A request is received relating to a specific row of the database table. An index that includes entries for each row of the database table stored in the memory device and entries for a subset of the rows of the database table stored in the disk device is accessed. A connection is made to the memory device if the specific row is stored in the memory device, and a connection is made to the disk device if the specific row is stored in the disk device. An action related to the specific row is performed based on the received request.

Index for hybrid database

A method for giving a destination call to the control system of an elevator system is provided, in which method one or more predetermined departure floor-destination floor pairs are presented on the touch-sensitive display of a destination call-giving device having a touch-sensitive display, in which each pair identifies for the user one predetermined departure floor and one predetermined destination floor, and the departure floor-destination floor pair selected by the user is determined on the basis of a touch detected with the touch-sensitive display, and a destination call signal is sent to the control system of the elevator system, which signal identifies the departure floor and the destination floor of the departure floor-destination floor pair selected by the user. A call-giving device, an elevator system and a computer program product are provided to implement the aforementioned method.

A method and arrangement for optimizing performance and data safety in a system includes first and second database servers coupled to a communication network. The first database server accepts transactions from a client application, stores them according to a data storage method, and sends them to the second database server via the communication network, whereupon the second database server also store the transactions. The first database server receives information about the server availability state of the second database server and detects changes in the availability state of the second database server in a such manner, that the data storage method of the first database server is changed according to the change in the availability state of the second database server.

The invention is in the area of distributed system and database security. The invention relates to a method and an arrangement for increasing the level of trust between a master and a replica database by allowing the master database to perform an 'unpredictable' audit of the replica database whenever deemed appropriate by the master database. The master database may for example define and generate an audit application and send it to at least one replica database using push synchronization and force the replica database to perform the audit application. The master database may also prepare expected results of the audit of the replica database and store them for later verification. After auditing the replica database may synchronize the results of the audit back to the master database for verification. The information flow between the master and replica databases is advantageously encrypted in a secure manner.

This invention relates generally to database servers and computer systems and, more particularly, describes the mechanism to run transaction operations originating from a primary server used to replicate data in parallel in a secondary server. Especially the invention relates to running concurrent or parallel operations in a secondary server for redundancy, recovery and propagated transactions. This invention describes how parallel operation in a secondary server improves performance and availability and how it maintains transaction order and output congruent with the primary server where transaction operations are originated.

A management of distributed databases, and a method and an arrangement associated with managing database schemas and configuration of software that uses those schemas. A method and a system, which allows managing database schemas and application software in large distributed multi-database systems and avoiding problems that are related to the prior art systems preferably by using a configuration manager apparatus (), which is external to the configuration and databases being managed () or by providing a mechanism for keeping multiple, possibly different database schemas and application software in synchronization. The external configuration management node () manages the configuration management replicas () in each part () of the distributed database system (). These synchronized configuration management replicas comprise scripts that are used for creating and/or updating the schemas of the database nodes and configuration of software that uses these database nodes ().

Method and arrangement for the management of database schemas

A plurality of steps, which are intended to modify the data in a transaction, form a transaction (40) comprising statements (41, 42, 43). In the method according to the invention there is formed a data exchange space (47) common to the transaction in order to make the parameters available to the statements belonging to the transaction and in order to transmit data between the statements belonging to the transaction. The system (30) maintaining the first version of the database is arranged to store the modifications to be made in the database as transactions, which comprise statements as well as parameters, both regarding the statements and regarding the transaction. The system (31) maintaining the second database version is arranged to form a transaction on the basis of the message it receives, whereby the transaction comprises statements, and to reserve an information exchange space (47) in the system memory in order to make the parameters available to the statements belonging to the transaction and in order to transmit data between the statements belonging to the transaction.
