need help on day light savings

Hi All,

i am working on UK based project and on 29th of March we are participtating in day-light savings activity.

Our OS provide will make the time settings and we will restart the servers.we are using AIX and DB2 combination.

As I am not aware of the process, I need an interesting doubt in my mind.

a. Do we need to applly any SAP NOTE to our application or Do we need to make any configuration settings?

b. Do the OS provider need to apply/upgrade any OS related patches as directed by SAP. if yes please let me know the SAP note number.

Thanks in Advance,

Mohan K
