Candido, thank you for your answer! But I need to clarify some points.

  Sorry, I did not understand that. After upgrading 8.1.5 to 8.1.7 I have a single instance 8.1.7
database. And I have no a 9.2 RAC database at this moment. Should I install a starter 9.2 RAC
database besides Oracle software before upgrading from 8.1.7 to 9.2? Or do you imply that I should move datafiles of 8.1.7 database to raw devices, rename them in control file and init.ora and 8.1.7 will work with these raw devices? And then I should do the upgrade to 9.2 RAC?

  Should I create additional redo logs for 8.1.7 and rename all redo logs to the
format which is recommended by Oracle for RAC? But 8.1.7 does not know about threads...
