Axxon PSIM™ software servers and Remote Admin Workstations configuration parameters are stored in the distributed database. Each server and Remote Admin Workstation store local copies of the distributed database. Local database copies should be synced to provide distributed operation of Axxon PSIM™ software and data replication (synchro alteration of local database copies).

The following synchronization mechanisms are used in Axxon PSIM:

  1. Internal synchronization. All changes are applied to computers automatically. This mechanism is used by default and does not require any further configuration. Internal synchronization can be disabled – see Configuring internal synchronization.
  2. DB synchronization of recipients with sources when starting Axxon PSIM:
    1. Configuration synchronization (see Configuring database synchronization).

    2. Configuration and protocol synchronization (see Configuring database synchronization and make changes to sync.xml file).

      Note.

      DB tables that are not synchronized during synchronization are in the sync.xml file. It is highly recommended not to change this file.
    3. Only protocol synchronization (see Configuring the Event Viewer databases synchronization).

In the simplest case, database synchronization is performed for all servers and Remote Admin Workstations with the database of the administering server.

Note.

The Remote Client has no database; therefore the administering server database should not be synced with it.

If any selected subnets are present in the system, the servers and Remote Admin Workstation databases should be synced with the node server or Remote Admin Workstation database (see, for example, figure below).

For example, to set up database synchronization for the servers of the distributed system shown in the figure, you need:

  1. to sync the databases of 1.2, 1.4, 1.5 servers with 1.1 Remote Admin Workstation database;
  2. to sync the databases of 2.2, 2.4 servers and 2.5 archiving server with 2.1 Remote Admin Workstation database;
  3. to sync databases of 3.2, 3.4 servers and 3.5 archiving server with 3.1 Remote Admin Workstation database;
  4. to sync databases of 3.1 and 2.1 and Remote Admin Workstations with 1.1 Remote Admin Workstation database.

For detailed instructions on database synchronization setup see Axxon PSIM™ software database management.
