Global Preference Settings

You can globally change the Cognos Transformer preference settings stored in the
cogtr.xml file from the command line or using the Preferences property sheet,
accessed from the File menu in Cognos Transformer. The cogtr.xml file is
automatically checked on startup for missing or invalid entries.
If you change the default selection for any option using the Preferences property
sheet, you must click OK.
AutoPartitionOff Setting
A setting of 2 ensures that model files imported into the current version of Cognos
Transformer switch to use the Auto-Partition feature, unless one or more cubes in
the model contain features that preclude use of this default optimization method.
A setting of 1 was used in previous versions of Cognos Transformer to signify that
Categories optimization was used.
MultiFileCubeThreshold Setting
The MultiFileCubeThreshold setting in the cogtr.xml file is used to enable creation
of multifile PowerCubes when your cubes exceed the 2 GB threshold. The default
value of 0 means that multifile cube generation is disabled. To test or use the
multifile feature on smaller cubes, we recommend that you specify a smaller
number for this setting, such as 1000000.
Cognos Transformer uses this setting to determine the number of output .mdp
(multidimensional partition) files that are needed to build the multifile cube. For
more information, see the section "Automatic Creation of Multifile Cubes" on page
170.
CenturyBreak Setting
Although this setting is not automatically created in the cogtr.xml file, you can
specify a CenturyBreak value to determine whether two-digit years (YY) in six-digit
dates are interpreted as dates in the 20th or 21st century. Cognos Transformer
stores values below the cut-off date as 21st century dates.
The default setting of CenturyBreak=20 signifies that dates 00 to 19 are interpreted
as the years 2000 to 2019, and 20 to 99 were interpreted as 1920 to 1999.
You can enter any value for this setting from 0 to 99. For example, for
CenturyBreak=10, all YY values between 00 and 09 are interpreted as 21st century
dates, and all YY values at or above the cut-off date are interpreted as 20th century
dates (that is, 1910 to 1999).
If your legacy data includes overlapping dates in two centuries (such as, 1900 to
1999 and 2000 to 2020), you must change your source data to use a 4-digit year
format (YYYY).
