Known Issues When Using Powercubes In The Ibm Cognos Studios; Not Yet Optimized Ibm Cognos Powercubes May Open Slowly In Ibm Cognos Bi - IBM Cognos User Manual

you want to use them as data sources to create content in the IBM Cognos BI
environment, you must generate the cubes and then publish the cube group.
Procedure
1. Open the Employee expenses model in IBM Cognos Transformer.
2. Generate the PowerCubes.
3. Publish the Employee cube group using the Publish PowerCube as Data

Known Issues When Using PowerCubes in the IBM Cognos Studios

Using Transformer, you can publish PowerCubes and their data sources directly to
IBM Cognos Connection, without using Framework Manager as an intermediary.
Documented in this section are known issues and limitations associated with using
PowerCubes in the IBM Cognos studios, such as Analysis Studio and Report
Studio.
Not Yet Optimized IBM Cognos PowerCubes May Open Slowly
in IBM Cognos BI
If PowerCubes created with previous versions of Transformer take too long to open
in the IBM Cognos studios, we recommend that you run a command line utility
named pcoptimizer, supplied with IBM Cognos BI, to improve run-time
performance.
This optimization utility is suitable for older PowerCubes when the model no
longer exists or the data used to build the PowerCube is no longer available. It is
not necessary to run this command line utility for cubes created in Transformer
version 8.x. and later versions.
Procedure
1. Back up your target PowerCube, then navigate to the c10_location/bin directory.
2. On Windows, open a command line window and run PCOptimizer.exe.
3. On UNIX/Linux, enter the following line to run the optimization command
All PowerCubes in the model are generated.
Source and Package option.
line utility:
pcoptimizer [-t] [-v] [-h]
cubename
where cubename is the fully qualified PowerCube or time-based partitioned
control cube name with the .mdc extension, if the PowerCube resides in the
same location as pcoptimizer. Otherwise, cubename is the full path with the
.mdc extension.
Note: This method only supports metadata extraction. To set up
user-configurable drill-through, you must use Transformer. Wildcard character
support is not currently available. You must therefore invoke the utility once
per PowerCube. If cubename is not provided, the program enters an interactive
mode, prompting you for a PowerCube name and accepting keyboard input.
The optional parameters are as follows:
-t or test mode; it tests whether the metadata was extracted and loaded into
v
the PowerCube. The return code indicates the status.
– 0 if the metadata was extracted and loaded
– 10 if the metadata was not loaded
