Option Description
D
A file-based WorkSpace is used. The work files are deleted after a
map is executed. All work files are deleted, except those being saved
for reuse as specified on the input cards for each map.
U
A file-based WorkSpace is used. A unique name is generated for
each work file created and the files are automatically deleted after
the map is executed. Unique work file names are useful if you are
running more than one instance of the same map at the same time.
Each time a map is run, a work file is created with a unique name,
which eliminates any conflict between work files.
M
A memory-based WorkSpace is used. This may enhance
performance for specific maps depending on work file requirements
and the amount of available memory by keeping the work file
information in memory and eliminating the I/O necessary with file-
based work files. If there is insufficient memory available to build the
work file, the map returns a
Disk write error message.
Note When this option is used, none of the other work file options
may be used. For example, deleting work files, unique work
file names, or specifying the directory.
= dir
Specify the directory path in which you want the work files to be
created. By default, work files are created in the same directory as
the compiled map (.mmc) file.
Retry (-Y)
The Retry execution command (-Y) is used to specify the retry rate for non-data
files accessed during map execution. This includes the compiled map file, as well
as, work files, the trace file, and the audit log. If one of these files cannot be
accessed at execution time, an attempt is made to access the file as specified.
-Y
count : interval
Option Description
count
This is the number attempts to be made to access the file.
interval
This is the number of seconds to wait between each attempt.
