First, you need the RMOPARM SETCMD=YES. This enables the SET operator command.
To set an initialization parameter while the product is running, issue the following command:
F RMOSTC,SET initparm = operand
Where: RMOSTC represents your STC name
initparm represents the initialization parameter you want to set
operand represents the value to which you want to set the initialization parameter
Initialization parameters that you can set with this operator command are listed below and are described in the chapter "Initialization Parameters" in the CA View Reference Guide.
