Definitions

  • the invention relates to a device for monitoring and coordinating
  • computers are connected to one another, for example via cable or radio, in such a way that they can exchange data with one another. They have the advantage that different people can edit or process data in different places.
  • Two computers that are connected to each other for data exchange form a small network.
  • the data exchange takes place via suitable protocols for the data exchange.
  • security aspects often have to be considered during the transmission, for example to prevent unauthorized persons from accessing data in the network.
  • Computer networks based on the “client-server system” are known, each of which has a central computer (server) to which various workstations (clients), ie computers dependent on the central computer, can access.
  • the data is stored centrally on the central computer.
  • the central computer manages the data stored there and, if necessary, the corresponding access rights to this data.
  • Client-server system has the advantage that in principle all network participants can access the same database.
  • a second computer with a parallel database is often set up so that if one computer fails, the other is still available.
  • security measures are particularly important when the data is particularly sensitive, such as for billing, personal data and the like.
  • Database can take on different tasks. In such devices, only the other computer is used as data backup.
  • the computers connected in this way are often technically extremely strictly connected to each other (via heartbeat line) and monitor each other.
  • the individual computers are often physically housed in different buildings or rooms.
  • the central computers are also monitored by system controllers.
  • the individual computers normally work with less power (for example 70%) in order to take over the work of the neighboring computer if necessary. This happens, for example, when one
  • the status of the individual computers is currently monitored using scripts. These are sequences of instructions or commands that are executed by the computer. These scripts can monitor other software. If the computer reports a computer as defective, a so-called failover is triggered. Unfortunately, this often leads to misinterpretations. It can happen that one computer signals avoidable malfunctions to the other, although it is full is functional. The other computer then takes over the functions and tasks of the other computer. It happens that the same database is processed by two different computers. Organizationally, this leads to great chaos.
  • the object of the invention is to eliminate the disadvantages of the prior art and to provide increased reliability, it does not lead to misinterpretations
  • the object is achieved in that in a device for monitoring and coordinating computers in a computer network of the type mentioned at the outset, in which
  • Computers are provided to the central computer unit.
  • the object is achieved by a method for such a device for monitoring and coordinating computers in a computer network according to the type mentioned at the outset, in which a central computer unit as
  • Monitoring and coordination system is integrated in the computer network, status changes of the individual computers being transmitted to the central computer unit.
  • the invention is based on the principle of designing the computer network in such a way that a central computer unit initially monitors individual computers in the network. For this purpose, the status of the computer is constantly transmitted to the central computer unit. This then decides whether a computer in the network has failed or not. If the If the central computer unit detects a failure or a malfunction, it is only authorized to coordinate the individual computers with regard to the further procedure. With this facility for monitoring and coordinating computers in a computer network, one is no longer dependent on the unsafe scripts, in particular for coordinating the computers.
  • An advantageous embodiment of the invention results from the fact that the means for detecting and transmitting status changes are designed as a program module on the individual computers. It is often sufficient to run a program module on the individual computers, which first records the status and then transmits it to the central computer unit.
  • an advantageous alternative to the software solution results from the fact that the means for detecting and transmitting status changes are designed as hardware components in the individual computers. In principle, software and hardware solutions can also be present in parallel in the computers.
  • the central computer unit advantageously has means for assigning functions and / or tasks.
  • the tasks and / or functions of one computer e.g. in the event of a signaled malfunction, all or part of it can be assigned to another computer, which then takes over these tasks and / or functions accordingly.
  • the central computer unit has means for transferring functions and / or tasks of one computer to at least one other computer.
  • failure protection is provided in the individual computers of the computer network and transmits information about malfunctions to the central computer unit. If failures or even total failures occur in a computer, this measure is suitable for transmitting information regarding the malfunctions of the central computer unit.
  • the central computer unit has means which actively query the status of the individual computers. This allows the central computer unit to determine, for example, at what point in time it would like to process the status of an individual computer or which computer should be queried. It can also be easily prevented that all status messages arrive at the same time.
  • the central computer unit has a graphic operator unit. This makes it easier to operate such a unit.
  • the graphic operator unit is then preferably virtual, in particular as a web
  • An advantageous embodiment of the method according to the invention for a device for monitoring and coordinating computers in a computer network results accordingly in that the transmission and detection of the changes in status of the individual computers take place via a program module. The status is first recorded and then transmitted to the central computer unit.
  • An advantageous alternative to the software solution arises when the method according to the invention is designed if the detection and transmission of changes in status takes place via a hardware component in the individual computers.
  • a further preferred embodiment of the method according to the invention is that the central computer unit transfers the function and tasks of one computer, in particular in the event of malfunctions, to another computer.
  • the status changes are preferably transmitted in encrypted form or via secure channels. This prevents access to the status data and, for example, manipulation by unauthorized persons.
  • the status changes are transmitted via the intranet.
