we recently upgraded to 11g, after that in one of our system brconnect is getting failed with error as below when i run it using DB13
BR0252E Function GetDiskFreeSpaceEx() failed for 'O:\ORACLE\<SID>\SAPDATA1' at location BrDiskStatGet-5
BR0253E errno 5: Access is denied.
BR0277E Determination of disk volume status for O:\ORACLE\<SID>\SAPDATA1 failed
However, if a run it at os level command line, it runs fine, can anyone give me idea about this?
