Parameters maintenance for Oracle 10.2.0.4 on Solaris 10 zone

Question

Hi!
We use SAP Solution Manager 7.0 on Solaris 10 Zone with Oracle.
We have updated Oracle from 10.2.0.2 to 10.2.0.4.
What are the parameter recommendation for Oracle 10.2.4?
What is the approach to do this?
Thank you very much!
regards
Thom

> Does the SAP installation usually include the setup of oracle parameters?
partly.

No. Many of those parameters (the events mainly) depend on specific patches that need to be installed to activate them. Did you apply all the interim patches for 10.2.0.4 or just that patch?

all of them are more or less important. Oracle is a complex beast.

You can use brtools to change them one by one - or write a script like the following. However, this implies that all single/interim/cumulative patches are installed, not only 10.2.0.4.
Check note 1137346 - Oracle Database 10g: Patches for Release 10.2.0.4 for the single patches and read all the linked notes to the patches so you can built your own script to set the parameters.
This is an example script for HP-UX but you could use a likewise one for Solaris:
alter system set
event='10027 trace name context forever, level 1',
      '10028 trace name context forever, level 1',
      '10183 trace name context forever, level 1',
      '10191 trace name context forever, level 1',
      '10629 trace name context forever, level 32',
     '10891 trace name context forever, level 1',
      '14532 trace name context forever, level 1',
      '38068 trace name context forever, level 100',
     '38085 trace name context forever, level 1',
     '38087 trace name context forever, level 1',
     '38095 trace name context forever, level 1',
     '10411 trace name context forever, level 1',
     '44951 trace name context forever, level 1014',
