Hi Salameh,
I'm writing the steps. If you can't set the parameter please ask to a DBA.
Cancel the SAP upgrade
in CMD screen
sqlplus "/ as sysdba" alter system set "_use_zero_copy_io" = false scope = spfile; shutdown immediate; startup; show paremeter _use_zero_copy_io;
After starting the Oracle, in same screen you must see the parameter value as FALSE.
Start the Upgrade again.
Regards
Tutku
