SAP R/3 System Profiles – Default Profile, Start Profile and Instance Profile

What are SAP Default, Start, Instance Profiles?

  • Profiles contain parameters that specify how to startup an instance and how to setup the various variables that define the way the SAP instances and system work.
  • Path: <SAPMNT>\<SID>\SYS\profile\
  • Example:D:\usr\sap\DEV\SYS\profile\
  • Only the Central Instance Host file system contains the profiles for all instances.
  • Dialog/regular instance hosts do not have any profiles stored on them.
  • If you have N instances on a SAP system (sharing the same SID) you will see 2*N+1 profiles files and their corresponding backup files if any in the SYS/profile folder.
