Definition

The MULTIPROCESSOR parameter in the Informix ONCONFIG file specifies whether the database server performs locking in a way that is suitable for a single-processor computer or a multiprocessor computer.

With this parameter you can adapt the locking mechanism of the Informix database to your computer’s system architecture. For multiprocessor systems, make sure the parameter is not set to zero, since this causes the database to act as if there was only a single CPU.

Use

To determine how to set this parameter, you need to take account of a range of factors. For more information, see:
