Nologo Option; O Option - IBM Cognos User Manual

In interactive mode, the Cognos Transformer application window opens and the
user is prompted for information, such as logon credentials, in the same way that
they are prompted when Cognos Transformer is opened directly. No information is
added to the log file when the supplied logon credentials are not valid. In batch
mode, the user is not prompted for information when Cognos Transformer runs,
even when the information is required. This is expected behavior.
The syntax for using the -n option is as follows:
cogtr -ndisplay_state -p
filename.py?|-mfilename.mdl
The following example opens the model file Roofing.mdl without displaying an
application window, and creates its defined cubes:
cogtr -n2 -mRoofing.mdl
The following example opens the model file Roofing.mdl displaying an application
window, creates its defined cubes, and then saves the model file.
cogtr -n -s Roofing.mdl

-nologo option

This Windows-only option prevents the display of the Cognos Transformer splash
screen.
The syntax for using the -nologo option is as follows:
cogtr -nologo -pfilename.py?|-m
filename.mdl
The following example opens the model Roofing.mdl without first showing the
splash screen:
cogtr -nologo -mRoofing.mdl

-o option

On Windows, this option regenerates the categories after a model load, but
disables cube creation. On UNIX and Linux, it loads the model file, but turns off
population of the model with data and cube creation.
On Windows, use this option in combination with -n to open Cognos Transformer,
perform the specified action in batch mode, and then close Cognos Transformer.
The syntax for using the -o option is as follows:
cogtr -o -pfilename.py?|-m
filename.mdl
The following example opens the model file, Roofing.mdl, saves any changes to
the structure, such as new categories, then closes Cognos Transformer without
creating any cubes defined in the model.
cogtr -s -n -o -mRoofing.mdl
The following UNIX/Linux example loads the file, go_sales.mdl, but disables both
population of the model and creation of cubes:
cogtr -o -mgo_sales.mdl
