Planning the Configuration

Before you create a multiplex, consider hardware and software requirements.

• Multiplex Storage Requirements
  Create multiplex stores on the appropriate device.
• Main Store Requirements
  Make sure that your main store meets prerequisites for multiplex operation.
• Hardware Requirements
  An SAP Sybase IQ multiplex requires shared storage for data on IQ_SYSTEM_MAIN, IQ_SHARED_TEMP, and user dbspaces.
• Java External Environment in a Multiplex
  Before you can use Java external environment UDFs in a multiplex configuration, install the Java class file or JAR files on each node of the multiplex that requires the UDF.
• Multiplex Planning Worksheet
  Before creating a multiplex, check that the paths of proposed objects meet requirements.
