Brtools is giving error

Hi

I have done Kernel upgrade.System is up and running.But Brtools is not working.

BR tools report the following types of errors:

BR252E Function fopen() failed for

'/oracle/DEV/sapcheck/avxserd.ext' at location main-8

BR121E Processing log file /oracle/DEV/sapcheck/avxserd.ext failed

BR252E Function mkdir() failed for '/oracle/DEV/sapbackup' at

location DirCreate-1

BR231E Backup utility call failed

BR253E errno 13: Permission denied

BR278E Command output of 'LANG=C dd obs=64k bs=64k

if=/oracle/DEV/sapbackup/cntrlC11.dbf of=/dev/rmt/1mn':

Please suggest.

Thanks,
