The following conditions are required for the use of the high availability mode:

 

- 2 serves with Windows server operating system

- 2 Enterprise servers

- Module network logon (suggested)

- Task service activated

 

In order to provide for a highest possible safety, it is suggested to install two Enterprise servers each on an own Windows server machine. One of the servers is used productively. On that machine the master database operates. The backup server makes the slave database available. Both servers have to be activated properly before the configuration.

 

With the  "network logon" a changeover can be made possible very quickly by means of the adaption of the profile. Alternatively the network logon file can also be created before, in order to be only allocated or copied to the accordant place in the case of disaster.
