Multiplex Server Architecture

Multiplex is multiple instances of SAP Sybase IQ servers running on multiple machines. SAP Sybase IQ supports read-write transactions from multiple servers in the multiplex.

Each server has its own temporary store and catalog store. The shared IQ Store is common to all servers. The primary server, or coordinator, manages all global read-write transactions and maintains the global catalog. The table version log (TLV log) stores information about DLL operations and communicates information about new table versions to the secondary servers.
