A server task is a
user kernel thread (UKT). The main purpose of server tasks is to parallelize database functions such as saving to a group of parallel media, restoring from a number of media in parallel, and index compilation.When the database parameters are being configured, the number of server tasks is determined automatically from the number of
data devspaces and the number of data backup devices in use. The maximum number of server tasks available is defined by the MAXUSERTASKS database parameter.
