IBM Spectrum LSF Data Manager 10.1 Fix 563618 Readme File
Abstract
P103914. This fix enables the user to choose whether or not perform a strict check when data manager tries to create a symbolic link if the source data file is accessible on the data server.
Description
Readme documentation for IBM Spectrum LSF Data Manager 10.1 including installation-related instructions, prerequisites and co-requisites, and list of fixes.
This fix introduces a new parameter to let the user choose if data manager needs to perform a strict check when creating a symbolic link for a source data file.
ACCESSIBLE_FILES_STRICT_CHECKING = Y | y | N n
This parameter takes effect only when CACHE_ACCESSIBLE_FILES=N (default).
If set to Y or y, when the data manager tries to create a symbolic link to a local accessible file, the data manager checks if the local accessible file and stage area are on the same NFS mount. If they are on the same NFS mount, the data manager creates a symbolic link to the accessible file. Otherwise, the transfer job is initiated.
If set to N or n, the data manager does not perform the check and directly makes the symbolic link if the data file is accessible on the data server. Make sure the file is also accessible on the job execution hosts.
For example, the source data file is on another NFS mount point instead of the stage area NFS mount point, while both data servers and execution hosts have the 2 mount points. The job fails to stage in the source data file if the file is not accessible on the execution hosts.
Default : Y - The data manager checks if the source file and stage area are on the same NFS mount points.
