Post installation stpes after upgrading the patch 10.2.0.4

HI,

i am following the guide Oracle Upgrade 10g Release 2 on UNIX, and i have upgraded the Oracle patch from 10.2.0.2 to 10.2.0.4 after the SAP installation. But i am not sure about the post installation steps which i need to perform, becuase this guide describe the database upgrade from 9i to 10g, but i was already in 10g so i am not sure what exaclty i need to follow. Could you please suggest me.

Regards,

Subhash
