Stop Validation (-V)
The Stop Validation execution command (-V) specifies to stop validation at the
card where the first error is detected. When this command is used, validation
occurs only through the input card where the first error is encountered. Map
execution is stopped after validating that input card, even if there are multiple
input cards.
Under certain circumstances, multiple errors are detected during validation. You
can stop (using -V) at the first error detected or continue (no -V) validating data
until all errors are found.
If you use the -V command, validation only occurs through the input card where
the first error occurred. It stops executing the map after validating that input
card, even if there are multiple input cards. If the -V command is not used, the
Validation > OnValidationError setting is used.
In all situations, if an error is found in the input, no output objects are built.
WorkSpace (-W)
When you run a map, the Command Server uses its own paging scheme to access
information about the data as efficiently as possible. Portions of both workspace
data and actual data are paged as needed. The workspace can be either a
combination of files and memory or memory-based. When file-based workspace is
used, the amount of memory accessed at a given time depends on the number of
pages and the count of pages configured for map execution.
When the WorkSpace execution command (-W) is used without other specified
options, a file-based WorkSpace is used and the work files are named using the
map name; they are placed in the same directory as the compiled map file. If the
-W command is used without a corresponding WorkSpace PageSize execution
command (-
P), the WorkSpace settings in the compiled map are used.
You can optimize the speed of map processing using the workspace configuration
setting. When processing a large amount of input data in a map, use the file-
based workspace with default paging. When small amounts of data are processed,
smaller page sizes and memory-based workspaces are recommended. When using
burst processing, adjust the workspace configuration for the size of burst data.
