RMAN-00556: could not open CMDFILE "/usr/netvault/tmp/00156001560000000001"

This error happens when Oracle user can't write data to NetVault related files or read data from them. For example, this situation can happen when NetVault is installed with non-default umask such as "077".
Re-install NetVault with default umask of root user - "022".
