This option pertains to OEM-specific abilities to change the number of sessions under program control. The internal variable, ct_mxu1, which controls memory allocations and for loops was not properly handled when SESSVAL() and SESSINC() were used. This fix sets ct_mxu1 to the activation limit when SESSCHG_ENABLE YES is added to the server configuration file. If this entry is not in the configuration file, then calls to SESSVAL() and SESSINC() will return NSUP_ERR (454, not supported).
Note: SESSCHG_ENABLE should not be considered for general use.
