ADM100 Lesson: How the System Evaluates its Parameters
There is only one default profile (DEFAULT.PFL) for each SAP system, and
it is read by all instances. It contains system-wide settings, such as the
system name, the name of the database server, the name of the enqueue
server, or also the default logon client.
The instance profile (__)
defines parameters that apply for one instance, such as the number
and type of work processes, or the definition of the size and allocation
of the main memory area used by the SAP system, and is therefore
instance-specific.
Figure 34: Viewing System Parameters
Demonstrate how transaction RZ11 can be used to display the values
and information for the individual system parameters. Execute report
RSPFPAR and restrict your search to rdisp*. Explain the meanings of the
System Default Value and User-Defined Value columns. Display the short
description and details for selected parameters (rdisp/wp_no_dia).
The current values of the system parameters can be displayed in the
system. There are two ways to do this. These are: report RSPFPAR and
transaction RZ11. Both functions display the system parameters for the
instance to which the user is currently logged on. Report RSPFPAR
displays a list of all instance-specific system parameters, along with the
parameters that apply system-wide. You can restrict this list to specific
parameters. A table displays the system default value for the individual
parameters, as it is defined in the program code of the kernel, and, if the
default value has been overridden by a profile parameter, the user-defined
value. A short description and, if required, documentation for the
parameters can also be displayed. Transaction RZ11 displays information
