Tandem Capacity Model (TCM) Manual

For example, the original file bank.HST is renamed _ank.HST, and the converted file is now named
bank.HST. A Microsoft Excel dialog box shows when the conversion is done.
• The Performance Models (the .SPM and .WPM files) created by pre-G06 TCM product versions
will not open (the Work with an Existing Model of the TCM Initial menu) in G06 TCM. To
migrate these old Performance Models to this RVU:
1. Select TCM Initial Create a new Performance Model.
2. Create the new Performance Model from the corresponding Workload Apportionment
model (.WWA file), or the CSV file and the Apportionment Method (.AWA file).
• The charts created in the pre-G06 product versions will not open in G06 TCM through the
Open option of the File menu. To regenerate these charts, use the Create Timeline Chart option
in the Chart menu of the TCM toolbar. Also, from the TCM G06 onwards, the charts are saved
along with the model, so saving the charts as a *.CPM file is no longer an option.
Loading Models From Other Folders
If you need to load a TCM model created by another user, or if you have renamed your distribution
or custom folder do not open the Workload Apportionment model (.WWA file) or the Performance
Model (.WPM file) as you would normally do.
The .WWA and WPM files are pointer files containing path names, and these files become invalid
when folder names or paths change.
To open a TCM model after such a change, use the .SWA or .SPM files the first time. Once you
open a .SWA or .SPM file, its new .WWA or .WPM file is created, and you can once again work
with the pointer files.
Other workspace files, such as .HST or .AWA files, can be opened as part of your normal session
activities and require no special handling.
To load a TCM model created in another folder:
1. From the “TCM Initial Menu” (page 66), select Work with an Existing WA Model or Work
with an Existing Performance Model and then click OK.
The Open PM Model or Open WA Model dialog box appears.
2. To view all possible Workload Apportionment models, type *.SWA in the Model to Open
field. Type *.SPM to see all possible Performance models.
3. Choose a file from the list or type the name of the file you want to open, including its .SWA
or .SPM extension.
4. Click OK. TCM loads the model file (rather than the Excel workspace file).
5. Click File Save to resave the model.
