Appendix B:
Timeout Configuration
Timeouts ensure that certain operations are carried out within a finite period of time, and the resources that they use
are returned for re-use. This document describes the various timeout parameters used by Equalizer, which can be
divided into two major groups:
•
connection timeouts
-- used by Equalizer to manage connections to the clients on the network and the
servers in clusters
•
probe timeouts
-- used by Equalizer to manage the various server health check mechanisms that assess
server availability
Most parameters are global and apply to all clusters; many can be overridden in the cluster settings.
