Abstract
General-purpose, high-availability database systems have lately proliferated to various network element platforms. In telecommunication, databases are expected to meet demanding availability levels while preserving the required throughput. However, so far, the effects of various high-availability configurations on overall database performance have not been analyzed. In this paper, the operation of a fully replicated, hot-standby database system is presented, together with some performance tuning possibilities. To study the effect of several database-tuning parameters, a telecom-oriented database benchmark, TM1, is used. The experiments involve varying of the read/write balance and various logging and replication parameters. It is shown that, by relaxing the reliability requirements, significant performance gains can be achieved. Also, it is demonstrated that a possibility to redirect the log writing from the local disk to the standby node is one of the most important benefits of a high-availability database system.
