Change SAP Profile Parameters

[Former Member]

The following three types of parameter files are defined in SAP system.

Usually at “/usr/sap/<SID>/SYS/profile” directory. 

1. Default –DEFAULT
2. Start profile - START_DVEBMGS00_
3. Instance profile - SID_DVEBMGS00_

These parameters change the system settings.  Those parameters can be changing though RZ10 transaction.

Changing Profile parameters can be done changing the parameters on DEFAULT and Instance profiles.  The profile type will be changed according to the system architecture. 

• Multiple application servers  : Use DEFAULT profile.
• Single Application servers : Use Instance Profile

After complete ring the parameter change the SAP instance should be restarted.

Ex: Removing multiple logon for sap system

Parameter:                         login/disable_multi_gui_login

Parameter values:           0 - allow, 1- not allowed multiple logon

Step By Step Procedure
