If SEC=NMSAF is in effect, there is an optional parameter file, accessed through DD SXCTL. You can use this file to customize the NMSAF facility to suit the security needs of your installation.
There is a sample SXCTL file in the PARMLIB member SXPARMS. For more information, see the comments in this sample file.
Note: If the SXCTL file is not allocated, then default settings are used for all parameters.
