摘要
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.
