Access to your database must be made through a server, which provides a communications channel and a manipulation device for the database.
A Sybase IQ server can dynamically start and stop a database, and accept connections from applications or users running on the same machine or on other computers by means of the network that links the two machines. Users can have connection rights to a database, not to the server. Sybase strongly recommends that you manage only one database for each server.
You can use multiple Sybase IQ servers to combine the use of Sybase IQ, SQL Anywhere, and Enterprise databases. You can also use multiple Adaptive Server Enterprise servers to combine the use of Sybase IQand Adaptive Server Enterprise databases.
A Sybase IQ multiplex is anSybase IQ database spread across a shared disk array. Each server in a multiplex runs Sybase IQ. Each set of an Sybase IQ Temporary Store and Catalog Store make up one server, and the servers share a common Sybase IQ Store.Users with large query loads and shared disk arrays may create a Sybase IQ multiplex to gain additional CPU power and memory space. A Sybase IQ multiplex supports many users, each executing complex queries against the shared database.
You can manage all Sybase IQ servers using Sybase Central.
