Are you running opreport on a different system than what you collected the profile data on? If so, you should check out the opimport function. If you do need to use opimport, see my posting from Nov 30, 2009, subject line "Re: question about oprofile on andriod mobile phone". -Maynard > > Regards, > > > ------------------------------------------------------------------------------ > SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, > Predictive Self Healing and Award Winning ZFS.
