ISSUE:“CMD.EXE was started with the above path as the current directory. UNC paths are not supported. Defaulting to Windows directory.” when running a Windows batch file as a pre or post command from a network drive (5233)

Article ID Reviewed AhsayOBM/AhsayACB Operating System
5233 10/03/2017 7.3.0.0 or above Windows

Problem Description:

When performing a backup job on AhsayOBM/AhsayACB the following error is shown in the backup log, if a Windows batch file is run as a pre or post command from a network drive or UNC path.

[YYYY/MM/DD HH:MM:SS] [info] [-] [Pre-Backup-1] xxxx.bat
[YYYY/MM/DD HH:MM:SS] [warn] [-] [Pre-Backup-1] '\\UNC_PATH\folder\'
[YYYY/MM/DD HH:MM:SS] [warn] [-] [Pre-Backup-1] CMD.EXE was started with the above path as the current directory.
[YYYY/MM/DD HH:MM:SS] [warn] [-] [Pre-Backup-1] UNC paths are not supported.  Defaulting to Windows directory.
[YYYY/MM/DD HH:MM:SS] [warn] [-] [Pre-Backup-1] 'xxxx.bat' is not recognized as an internal or external command,
[YYYY/MM/DD HH:MM:SS] [warn] [-] [Pre-Backup-1] operable program or batch file.

Cause:

Resolution:

A workaround for this Windows limitation is to use a batch file located on a local drive along with the pushd and popd commands to launch the batch file on the network drive.

Example:

Batch file : \\192.168.22.41\Production\current\shutdown_database.bat

1. Create an batch file and save on local machine to execute the batch file on UNC path or network drive.

2. Call the local batch file (localbatch.bat) in the pre or post command in AhsayOBM/AhsayACB.

localbatch.bat

echo on
pushd \\192.168.22.41\Production\current\
\\192.168.22.41\Production\current\shutdown_database.bat
popd
