Data base save fails after performing initial checks.
The save may just end after "Performing initial checks ..." or emit an error such as:
Error: The program Command failed moving /<SaveDirPath>/oracle_rman to /<SaveDirPath>/oracle_rman_prior failed
When performing a database save into a directory which has a previous save,
the save process renames the oracle_rman to oracle_rman_prior to preserve
the existing save in the case the new save fails.
Some of the reasons it may be unable to do:
1) There is a file open in the oracle_rman directory
2) The permissions on the oracle_rman directory have changed so it cannot be
renamed by the $NH_USER
The resolution depends on the root cause as noted above (correcting permissions,
making sure no program is holding files open in the oracle_rman directory).
The crux of the issue is the inability to rename oracle_rman to oracle_rman_prior
as the $NH_USER
