Starting the Coordinator
Starting the multiplex coordinator in single-node mode (-iqmpx_sn) and read-only (-iqro) performs some initial database checks. For coordinators, the server must reset an identity cookie before you can use the multiplex.
Manually Synchronize the Secondary Nodes
To start the secondary nodes, install SAP Sybase IQ 16.0, then synchronize from the coordinator node. When you migrate a query node, it becomes a reader node.
