Set event 100183 & 10027 in Oracle 11g

Question

Hi
    I have upgraded the Oracle 10.2.0.4.0 to Oracle 11.2.0.2.0 . while running the script provided by SAP vide note no. 1171650 (Automated Oracle DB Parameter Check) , following recommendation comes after running the scripts
means change the event to values like 1or 2 or 1024 etc.
event (38087)     change value to "38087"                     1
event (10183)     change value to "10183"                     1
event (10027)     change value to "10027"                     2
event (10028)     change value to "10028"                     2
event (10142)     change value to "10142"                     2
event (38068)     change value to "38068 level 100"     2
event (38085)     change value to "38085"                     2
event (44951)     change value to "44951 level 1024"     2
event (10191)     change value to "10191"     
event (10995)     change value to "10995 level 2"     
when i executed the command on sqlplus / as sysdba level
ALTER SYSTEM SET EVENT=
'10027 trace name context forever, level 2',
'10028 trace name context forever, level 2',
'10191 trace name context forever, level 1',
'38087 trace name context forever, level 1',
'10183 trace name context forever, level 1',
'10142 trace name context forever, level 1',
'38068 trace name context forever, level 100',
'38085 trace name context forever, level 2',
'44951 trace name context forever, level 1024',
'10995 trace name context forever, level 2'
COMMENT='SAP RECOMMENDED SETTINGS - 201108' SCOPE=SPFILE;
thereafter i shutdown the oracle & restart it , it either comes instead of "change" to  "add". It also don't give any error.
Can anybody be help in sort out that why these are happening. why it is not changing the values.
Thanks
Regards

Hi,
I think this will be the first time I do not agree with you.
probably you have not read the note.
the script cannot diferenciate between OLTP and OLAP, it expects that YOU tell him what typwe is and adjust the recommendations to that.
You can execute the relevant statement without adjustments for OLTP systems. For OLAP systems, you need to replace the string '<OLAP System? [n]>' with 'y'. Depending on the statement, the string may occur several times.
Of course, as it is "automatic" you haqve to understand the recommendations.
But i do really think that from that to say that it is rubbish there is a long way
