Table 24 lists the parameters in the ONCONFIG file that specify the configuration of the buffer pool and the internal tables in the resident portion of shared memory. Before any changes that you make to the configuration parameters take effect, you must shut down and restart the database server. For a description of the configuration parameters, refer to the IBM Informix Dynamic Server Administrator's Reference.
