To answer this question, we need to understand the different profiles in SAP system administration.
The parameter rdisp/mshost refers to the message server host. The message server is responsible for communication between different SAP instances in a system landscape.
Now let's go through each option to determine in which profile the rdisp/mshost parameter is found:
Option A) Default - This option is correct. The rdisp/mshost parameter is found in the default profile. The default profile is the central profile used by all instances in the SAP system.
Option B) Start profile - The rdisp/mshost parameter is not found in the start profile. The start profile is used during the startup of the SAP system.
Option C) Central instance – instance profile - The rdisp/mshost parameter is not found in the central instance profile. The central instance profile is specific to the central instance of the SAP system.
Option D) Application Instance – instance profile - The rdisp/mshost parameter is not found in the application instance profile. The application instance profile is specific to the application instances in the SAP system.
Therefore, the correct answer is Option A) Default. The rdisp/mshost parameter is found in the default profile.
