The SAP system for the Oracle database comes with a standard initialization profile for the database parameters:
UNIX
OS> <ORACLE_HOME>/dbs/init<DBSID>.ora
Windows
OS> <ORACLE_HOME>\database\init<DBSID>.ora
For example (UNIX):
/oracle/C11/dbs/initC11.ora
This profile contains the default parameter settings recommended for the SAP system. Copy this standard profile so that you can access the original parameters, if necessary.
