A Sybase IQ multiplex requires shared storage for data on IQ_SYSTEM_MAIN, IQ_SHARED_TEMP, and user dbspaces.
All machines running servers participating in the multiplex must have the current version of Sybase IQ installed. For upgrade instructions, see Installation and Configuration Guide > Planning Your Installation > Upgrading From an Earlier Version.
When you convert an existing simplex server to multiplex, it becomes the coordinator. For secondary servers, set up a computer with access to the shared IQ store using paths identical to those used by the coordinator.
Multiplexes of Sybase IQ servers at different release levels.
Heterogeneous multiplexes (UNIX and Windows servers in a mixed multiplex). Coordinator and secondary servers must be on the same operating system and hardware platform.
